What is the TSD data collection terminal and how to use it. Optimization of warehouse processes using data collection terminals Experience with TSD

As practice shows, many industrial and trading companies are characteristic of the inaccuracy and lack of efficiency in accounting of goods and materials in stock, and the inventory sometimes stops the workflow and takes too much time.

Warehouse problems that indicate that it is time to increase accounting accuracy:

a balance of goods;
irregular inventory that inhibits production or / and trade;
lack of control of the correctness of the placement of received goods in the warehouse, everything is placed on free spaces or at the discretion of the storekeners;
the search for goods in stock and the subsequent assembly of the order takes a lot of time.

All problems described can lead to a mess both in stock and in warehouse processes, possible damage to stored products and components, clients discontent due to long-term processing of orders, material costs in the event of the loss of goods and the difficulty of finding responsible for violations.

In particular, in the conditions of the crisis, when it is especially important to minimize losses and optimize business processes, such risks should be excluded. Therefore, management is especially important to formalize problems and allocate tasks and further steps to solve them.

And before your warehouse there are such tasks?

If the above problems are characteristic of your company, then it's time to think about solving the following business tasks:

Reducing time for the search and identification of goods in the warehouse;
Elimination of the balance of goods in the warehouse;
Minimization of the time of inventory in stock;
Reducing the human factor when performing warehouse operations (reception and shipment of goods, setting of orders, etc.).

A tool that will ensure accuracy of accounting in stock

There is a large selection of specialized equipment for automation of the warehouse and ensure the accuracy of accounting - data collection terminals (hereinafter referred to as the TSD).

TSD - These are portable devices equipped with a barcode scanner to read the codes of goods for their identification and accounting (Fig. 1).

When integrating the work of the TSD and the 1C accounting system, many problem areas of the warehouse can be closed.

Figure 1 - TSD in the work of the warehouse

Standard operations that are performed by TSD:

When taking goods. When the car brings the goods directly to the warehouse, the storekeeper loads the document to receive a reception on the TSD (at the same time it does not go to the computer, and the manager can reset the task to receive it directly on the CDS) and reads from the incoming barcode product. At the same time, all goods must be a barcode. If the incoming product has no barcodes, you can print them using a mobile label printer by sending a print command directly from the TSD. If the declared product does not correspond to the actual, then the data on the discrepancy of the storekeeper will see immediately on the TSD. After unloading data in 1C, you can reflect the actual arrival of the goods if you use the order.
When carrying out an inventory.The inventory process can be performed in two different ways. The first - the storekeeper reads the barcode and the actual residue and discrepancy immediately appear on the TSD. Thus, the storekeeper can immediately search the missing goods, or evaluate the reasons for the shortage or excess TMC. The second - the storekeeper itself turns the document on the inventory on the CDS and reads the position. After data synchronization, the actual information about the quantity can be downloaded to the inventory document to make a reference. Based on the received inventory statement already in 1C, the manager can automatically form the certification and write-off documents on the basis of discrepancies.
When shipping goods.When selecting the goods, the storekeeper also unloads orders on the TSD to assemble and reads the barcode from the selected goods. If the goods, the bar code from which is read, does not correspond to the order or diverge in quantity, the order for the CDS cannot be carried out, and the TCD issues an error.
When moving goods within a single warehouse.

Why for many companies, the acquisition of TSD turns into cash losses, and not in profitable investments?

Many owners, making a decision on the acquisition of TSD or charging this task with their subordinates, do not take into account or do not control the accounting of many factors that affect the efficiency of the use of equipment.

Based on our experience in the introduction of TSD in enterprises of different fields of activity, typical user errors can be divided into such groups:

There is no clearly built algorithm for using barcticing and storage of goods in stock. The use of a barcoding technique in a warehouse is possible with two ways to account for goods in stock:
- Address storage. With this method, the accounting system stores data on how much and what product is stored in each specific cell. At the same time, the employee must clearly comply with the recommendations of the system, in which cell the product is putting and from what to take. All operations for placement and selection of goods are performed using a TSD, which is read by the barcode of the product code and barcode code.
- Information accounting. Information is entered into the system where the goods should be stored approximately, but there is no data which product and in what amount lies in the specific cell at the moment. Employees can place and select the goods in one of the recommended cells of the cells, independently analyzing the availability of free space. It is not necessary to reflect in the system with the help of a TSD, which cell the product is laid or from what is selected. The system controls the correctness of the selected and placed goods, as well as its number.
There is no formalization of tasks that the TSD should solve and understand the necessary requirements for functionality.
The conditions in which the TSD will be used are not taken into account.

Thus, the acquired equipment or does not completely solve all the tasks, or vice versa, the functions in excess, which creates an impression of empty spending of money and the high costs used by software.

Recommendations that will make the process of implementing and using the TSD effective

Selection of model TSD
- Data collection: The ability to scan barcodes (both linear and two-dimensional) and radio labels (RFID). Everything will depend on the product labeling technology chosen.
- Screen features. What information and in what volume you want to see on the TSD screen.
- Memory amount - how many information about commodity units can store the terminal before transferring to the system. The choice will depend on the turnover of goods.
- Battery level - how much battery life can withstand the terminal. How many shifts of the storekeners are in the enterprise, how much TSD are you planning to buy, and do not forget that the TSD will also be used daily at acceptance, shipment of goods and collect orders.
- Communication method with accounting system (docking station, Bluetooth or Wi-Fi).
- Impact resistance, heat resistance and other characteristics of the terminal, which indicate its perception to external factors, which will allow you to determine how long the device will last. Your warehouse is warm or cold, dusty or sterile, is outdoors or indoors, where bad ventilation - in what conditions will the TSD be used?
- Price and supplier guarantee. The purchase of the terminal is a significant investment, where the ratio of price-quality is directly proportional, so pay attention to the warranty that the supplier gives, as well as additional installation conditions, connecting and testing performance.

The process of introducing TSD.

An integrated approach to the beginning of the use of the CDS, in particular, competent integration with the accounting system is important. The implementation process itself is recommended to split into the steps presented in Table 1. This approach will allow to evaluate the intermediate results and adjust its actions.

Stage of implementation	The result of a successful implementation
Installing and configuring driver	Installing software on TSD. The driver is connected and configured to work with a remote connection.
Connecting the TSD to the 1C and Wi-Fi network, if there is a need	TSD is connected to the 1C system. Connected processing for sharing information with TSD. Customized warehouse accounting operations on TSD: when collecting barcodes, scanning and product recognition occurs, their number is introduced; when shipping goods, checks and recalculate goods shipped from the warehouse; there is a viewing of real balance of goods from 1C, viewing real prices from 1C, printing actual price tags for the goods; when reassessing, it is possible to assign new prices, or identify existing; when accepting goods and coming to the warehouse, their check is performed and recalculated; inventory, data on the inventory statement in the database 1c with the real availability of goods in the warehouse is required. The test sharing of documents 1C and TSD.
Connecting printer printing labels for barcoding goods to the 1C system	Printers are connected. A label print template has been developed (if it differs from type). The customer determines the type of label

The table for visibility describes the integration of the TSD from 1C. If the company uses another accounting system, then for efficient work, it should provide: acceptance of the TMC to the warehouse, the placement of TMC on storage cells, shipment of TMC counterparties, Vacation of TMTs in the request of the requirement, inventory of the TMC on the respective warehouses, the movement of the TMC between various warehouses premises.

Selection of model TSD
Very often, the storekeners and other employees who will encounter TSD daily in their work can purposefully or unintently sabotage the implementation process. Therefore, it is very important to provide for the preparation of instructions, user training, as well as explanatory work and recycling of the system of motivation and demotivation (if such is used in the company).

Effect and benefits for the company from the introduction of the TSD

The consistent implementation of the TSD, as well as following the recommendations given in the article, will allow you to get the following benefits for business:

the ability to track the effectiveness of the storekeepers and other warehouse staff, increase productivity;
effective management of employees by integration with the accounting system - the ability to "transfer" people from order to order, track the speed and quality of tasks and other;
reducing theft, losses and errors due to the human factor;
increase the speed of work of warehouse processes (reception, placement and shipment of goods, inventory);
improving the quality of customer service primarily by increasing the rate of target collection.

The most important advantage for business owner is an increase in warehouse manageability.

The data acquisition terminal (TSD) is offline devices that can be read by barcodes and save information about them. This equipment is an indispensable tool in the work of shops, warehouses, logistics centers and other enterprises where automatic product identification is required.

You can buy a data acquisition terminal to solve such tasks as:

inventory;
mobile trade;
accounting of fixed assets;
transport logistics;
assembly, reception and shipment of goods;
mobile printing;
revaluation and many others.

Why buy TSD?

Available at the price of the model and expensive data collection terminals allow:

simplify administration in the company;
increase staff productivity;
improve the accuracy and reliability of operations produced;
accelerate the procedures performed;
reduce the number of allowed errors.

What to buy a data acquisition terminal?

If you want to buy a data acquisition terminal, it is worth paying attention to the simplest models. But at the same time it is necessary to take into account that they provide only reading and accumulation of information without further processing.
Of course, the price of more functional TSD will be higher. Mobile data collection terminals go with advanced features, which allows them to use them almost like full-fledged pocket personal computers (PDAs). They can be easily integrated into any account. The scope of this technique is very extensive.

The development of any business entity, whether it is an industrial enterprise or a service organization, is impossible without the introduction of modern technologies that help improve the processes of accounting and controlling the movement of goods, storing and analyzing information. For this, a number of special devices have been developed, which belongs to the electronic data acquisition terminal. It helps effectively solve issues of fast and accurate traffic, control and data processing, minimizing the influence of the human factor. What is the TSD how to use such an appliance? The answers to these and other questions can be found in the article below.

What is TSD?

Data collection terminal is a modern specialized mini-computer, which is designed to automate trading, accounting in stock and other processes. The electronic TSD consists of a processor, RAM, keyboard or sensory display. A device for reading a barcode is built into such a device. It can function in because it has its own operating system.

The operation of this device is based on reading barcodes. Warehouse farms, restaurants, pharmacies, small shops and large mega marketers are increasingly using electronic TSD in their activities.

Data Collection Terminal: How to use?

The photo below demonstrates the ease of use of the TSD. To introduce information, you just need to direct the laser beam scanner on the barcode. The built-in processor recognizes the code and automatically make further necessary operations. You can also enter data using the keyboard or touchscreen. This is necessary if any error occurred when scanning.

Such terminals can work both indoors and on the street. Industrial orientability devices are successfully functioning under negative temperatures, in conditions of high humidity or strong dustiness. High impact resistance and waterproof housing is a distinctive feature of such TSD. Motorola data collection terminal, for example, is equipped with a scanning head that can be rotated. This allows you to read the data at any angle of inclination.

Information from the terminal to the accounting system of the business entity is transferred through various communication channels. It can be an IR port, Bluetooth, Wi-Fi or USB. It depends on which model of the TSD (data acquisition terminal).

How to use this device? It all depends on the type of terminal used. There are six main types of TSD: the initial class, pocket PCs, full-size, with a pistol handle, wearable, transport. Each of these types of devices is described in detail below, and recommendations are given on the use of a terminal.

TSD of the initial class

This is the easiest view of data collection terminals. Such devices do not support WAN or Wi-Fi. All results obtained as a result of scanning or entering information from the keyboard are saved as a text file. To transfer data to the account, you need to connect to a CDD to a computer (data acquisition terminal) using a cord.

How to use this type of devices? Most of all, they are suitable for inventorying warehouse residues and fixed assets or collect data without connecting real-time to the account.

Pocket PC

Such terminals are miniature, but at the same time powerful devices. With their help, mobile employees can get full access to the information contained in the remotely posted database. PDAs are equipped with additional features such as Wi-Fi, GPS, Bluetooth, WAN (GPRS and 3G).

Laptop, telephone and scanner - all these devices can successfully replace such a TSD (data collection terminal). How to use the PDA? Ideally, it will come true for such employees who are often in the duty. These may be land leaders, freight forwarders drivers, delivery service staff.

Full-size TSD

Full-size terminals are like pocket computers. Their main advantage is the high efficiency of working with a wireless connection to the database. Such devices are equipped with a full-fledged keyboard. Also in full-size TSD embedding various types of scanners. It helps in solving all sorts of tasks.

Such devices can be used both inside or the distribution center and on the street, for example, on construction sites, or in truckers trucks. Some models of these terminals can function under water.

TSD with a pistol handle

The purpose of data collection terminals with a pistol handle is work in hard conditions with a connection to Wi-Fi. Such devices most often do not have the ability to connect to mobile networks. If there is no connection to Wi-Fi at some point, the terminal can be used as a data storage.

There are many diverse models of built-in devices for reading barcodes. Among them there are long-range scanners that can be equipped with TSD. The data acquisition terminal with a pistol handle, which built in such a powerful device, can count barcode from a distance of more than 9 meters.

The operation of these devices is characterized by high performance, they are durable and easy to use. Thanks to these qualities, the TSD with a pistol handle often use workers of warehouses or drivers of loaders. More terminals are widely used in retail. After all, with such an intensive use, simpler devices are quickly broken and fail, and the TSD with a pistol handle does not require repair and replacement.

Wearable TSD

The wearable terminals are able to perform the same functions as the TSD with a pistol handle, however, when working with them, the user's hand remains free. Such a device is attached to the wrist of the employee, the compact scanner is made in the form of a ring that should be put on the finger. The instrument management is performed using voice.

Wearable TSD are not too common, but with proper use they are able to significantly increase the efficiency of work.

Transport TSD.

Transport TSD has a solid construction, which allows them to withstand sufficiently strong vibration on the loading platforms and various vehicles. Such devices are not equipped with a built-in scanner. For more efficient operation, you need to connect a manual barcode reader to the TSD.

Most often, such devices operate on the basis of Windows Mobile, but there are models that function based on Linux or Windows XP. It provides a high computing power indicator that the electronic terminal has. The TSD of this type is used in the receiving goods, shipment or configuration. This accelerates the workflow and reduces the number of errors that arise due to the human factor.

Conclusion

TSD is a modern specialized mini-computer. It is designed to automate trading, accounting in stock and other processes. How to use the data acquisition terminal? It's not hard. You just need to direct the laser beam scanner on the barcode. After the code recognition, the processor built into the device will automatically make the necessary operations. The main purpose of using the TSD is to increase the performance of work to reduce the cost of time on the implementation of monotonous operations to collect and process information and to reduce the number of errors caused by the human factor.

Modern logistics and trade processes are difficult to submit without various automated devices and systems, whether it is a WMS system to control the warehouse or various automated racks. A variety of equipment and device manufacturers provides a large selection and the ability to choose the equipment under its specific needs. One such device is a data acquisition terminal (TSD). There are many different types of TSD from different manufacturers of equipment. Below we will look at what the TSD is, their types and their appointment.

What is a data acquisition terminal (TSD)

TSD is a specialized laptop computer intended for data collection, their processing and interaction with the information system in the organization. This is a type of equipment for

The simplest modification is a device size with a cell phone, with a built-in barcode scanner. The most complex models can work under water or at temperatures up to -50 ° C. With the help of the TSD warehouse workers handle trade turnover, shipping expenditure orders or make an inventory.

Principle of operation of the TSD.

The principle of operation of the TSD is reading information by scanning a barcode and further transmitting this information to the information system.

Also, the TSD screen may be given the tasks of the warehouse workers, and if additional functions, the TSD can be used as a printer or a negotiation device.

Transferring information to the information system is possible on wireless communication or when connecting the TSD to a computer through the cable.
Some TSD can be attached to the hand, and some are equipped with a pistol handle to relieve work.
There are also industrial data collection terminals scanning specialized types of codes or working in difficult external conditions.

How to use data collection terminal

It is enough to use the TSD, it is necessary to send a laser scanner to the barcode so that the terminal consider encrypted information. Next, this information is stored on the domestic drive, for subsequent transmission to the information system or is transmitted immediately over a wireless connection. The terminal itself is usually installed a special program for the TSD, which processes the scanned information.

Also, the terminal screen may issue tasks to warehouse workers, and if additional functions, the TSD can be used as a thermal printer or a negotiation device.

With the help of the terminal, you can carry out an inventory, to receive and ship goods, check the shelf life of the goods, check the correctness of the price tags in the trading room. When barcoding documents, the terminals can be used in document flow.

How does the data acquisition terminal

Transferring data to the information system:

After reading information from the barcode, the data then must be transmitted to the organization's information system. To do this, data acquisition terminals are equipped with various data interfaces.

Some terminals are connected to the information system in real time and data exchange occurs by wirelessly,
and some scan information to the internal drive and in the future transmit it when connected through the wire.
It is also possible to transmit information through memory cards.

Main ways to transfer TSD data:

Connecting a TSD through a wired connection. Connection Interfaces: RS232, USB. Sometimes the so-called cast stand is used (stand for the TSD connected to the PC). Perhaps several options for the installation of the CRED-stand is one-to-one (one basic stand + one data collection terminal) and multi-point (one stand + several scanners). The advantage of the wired compound can be calculated long time of autonomous work, because No need to spend energy to maintain communication channel. The disadvantage is the lack of permanent communication with the information system and feedback.
Connecting a TSD through a wireless connection. Connection Interfaces: Bluetooth, Wi-Fi, IrDA (IR port), GSM. There are restrictions on the working distance of the terminals: with a Bluetooth connection operates at a distance of 15 meters, Wi-Fi is up to 100 meters. IRDA is an infrared port, it works close up to 10 cm. To connect via GSM, information systems must have a modem for making a signal, it works in the zone of a stable signal of the cellular communication. Advantages in a permanent connection and feedback with the information system, always relevant information on the TSD. The disadvantages include a slightly large price than the conducted terminals.

Scanner work:

Modern barcode scanners have differences on the type of reader, decoded codesThe possibilities are read QR - codes and RFIDs - tags.

The reader device may be laser or LED.

Laser TSD are most common and used red diode laser. Scans a standard linear (1d) barcode of various sizes (up to several decimeters).
The LED scanner (image scanner) takes a snapshot of the barcode, and after analyzes and extracts information.
The image scanner can scan more complex barcodes (1D, 2D, mixed, damaged, QR-codes) and work at a distance of up to 15 meters.
RFID scanner - labels are not yet strongly distributed, but successfully combine several technologies (bar coding and radio frequency identification). Can be applied when labeling expensive products.

There are also specialized scanners for identifying codes made using direct labeling technology (DPM). Barcode application is possible by drilling, laser engraving, etching chemical reagents, extrusion (Perm-code) and other methods, depending on the type of surface. Such coding is often used in industrial production. The work of a simple scanner is hampered by the fact that the barcode is made on the surface itself, be it metal or polyethylene. Therefore, a special DPM scanner was developed.

Operating system

The data acquisition terminal is a specialized mini computer, with its processor, operational and long-term memory, and any computer should be managed by the operating system. For the TSD of such operating systems, several:

Old operating systems are found mainly on old models and has a number of restrictions. On DOS - the system mainly works only a specific software developed by the manufacturer of the device. You can also possibly software developed in such programming languages \u200b\u200bas C ++ or Visual Basic.

DOS - Terminals have a monochrome display, small computing power and an internal memory storage. It would seem that such terminals are not in demand and are already out of use, but with all disadvantages, such TSDs have several advantages over more complex terminals. Low power consumption and as a result, more work hours from one charge, system reliability, affordable price, which still allows you to compete in the equipment market.

Windows

This is the most common and flexible operating system for the data acquisition terminal. Windows Mobile is a more versatile system, can be used in various modern terminals, but for this operating system, increased system requirements. Considered a more popular operating system, because It has developed a lot of applications for all areas of trade and logistics. Windows CE does not require serious computing capacities and is flexible to use.

Android OS.

A newly new operating system that has recently appeared in the data collection terminal market. It is easy to use a smaller cost of developing applications for the terminal (compared to Win applications), the absence of complex software licensing. Interesting to small and medium businesses.

WMS relationship (thin client, thick)

To work on the data acquisition terminal of one device, there is still a little appropriate software. This software (TSD driver) is developed under the operating system installed on the terminal. Large developers of their own corporate information systems, develop their programs for TSD. Some equipment suppliers offer comprehensive solutions of TSD + drivers for popular IP (for example, under 1C). There are two approaches to the organization of the workplace.

Based on the "thin" client

For devices on the Windows operating system, Remote Desktop Protocol can be used, or Citrix MetaFrame Client. With their help, you can remotely display the contents of the desktop server. Also, to create a "fine" client, you can develop Web applications. In this case, the "thin" client will perform any supported web browser on the TSD. For terminals on the DOS operating system, it is possible to use Telnet. In this case, the application running on the Telnet server will be displayed on the TLC screen via Telnet-Client. The wireless connection mode provides an uninterrupted TSD connection with an information system. Such an approach is considered obsolete, because Equipment running DOS systems is becoming less and less.

Organization of a workplace based on the "Tolstoy" client

"Fat" client is an application designed specifically for a specific data collection terminal. The application can be designed for both offline mode and online. Modern operating systems in TSD (Windows, Android) allow you to develop various applications for the operation of the terminal. Cons "Tolstoy Customer" - this is a binding to the operating system, which the application was developed. There are risk of data loss if for some reason the data has not been transferred to the information system.

Interface (sensor, buttons)

In various terminals, various ways of entering information are used. It can be a keyboard with a different number of keys or a touch screen, a combination of a touch screen can also be combined with function buttons. The number of buttons will be varied both in the types of TSD and in models. The advantages of the touch screen can be attributed to the fact that the screen can output any number of buttons and their combination. For disadvantages - it is not always convenient to press the buttons on a small screen, it may suffer the accuracy of the input of information. The keyboard in the terminals are also different. In the simplest version, it will be the keys only with numbers. Some models have keys with numbers, each of which is assigned to your set of letters for the busting, and there are keyboards with a complete set of letters and numbers necessary for full input of information. The number of buttons in such terminals is different (12, 32, 53, etc.). Convenient is the terminal with function keys, up to 8 pieces. There are terminals with a full-fledged QWERTY-keyboard, but these are already specialized industrial models.

Additional features of TSD

There are models of terminals, with their own characteristics.
To some TSD models, you can connect an additional printer for printing barcodes, which allows you to print and replace the labels if an error is found in them.
It is also possible to have a camera, for additional shooting of objects and making information into the database.
Some TSDs in the form of a PDA have a GSM module and can be used as a cell phone.
Sometimes the TSD is completed with the backup batteries of a small container and size. In the case of the discharge of the main battery, the backup allows you to save the data and, if possible, transfer them to the IP.
There are models with an adjustable angle of inclination of the laser to scan the barcodes, which reduces the muscle load on workers, and this affects labor productivity.

Battery, autonomy

One of the main characteristics of the TSD is the battery life. Naturally, the more, the better. At a minimum of the TSD should be enough for one 8-hour working shift, and some models, with a large amount of battery, work up to 24 hours without recharging. Most models of data collection terminals are powered by Li-ion or Li-Pol batteries. The remaining from ordinary alkaline batteries or batteries of other types. Some TSD models complete there are removable batteries that can be replaced in "hot" mode. The advantage of this is to ensure the continuity of operation, but as a result of the price of such models above.

Temperature, protection

There are specialized scanners that can operate in a large temperature range, from -50 ° C to + 50 ° C. They have enhanced protection from the external environment, a solid housing, sealed connectors, shock-resistant glass. The TSD is also equipped with enhanced sound and light indication, to work in conditions of increased noise and limited visibility. Scanners have a rubberized case and withstand multiple drops from a height of up to 2 meters. Such scanners have a security class, which is determined by the international IEC standard 60529, is indicated by IPXY (X is the degree of protection against the penetration of foreign objects, dust. Y is the degree of protection against moisture).

TYPTS TSD brief overview

Data collection terminals can be divided into several generally accepted categories. There are also many different firms producing TSD. There are also separate services that produce TSD repair.

TSD of the initial classequipped with a simple barcode scanner and a small number of function keys. Intended for small organizations. The data obtained as a result of reading barcodes is stored on the device, and later transmitted to the information system by means of a wired connection. Setting up such TSD is minimal.

Benefits: Low price, ease of use, reliability.

Disadvantages: Lack of computing power with complex warehouse operations, little functionality, the need to connect to a computer for data transmission.

Many firms produce the TSD of the primary class

TSD with handle - A special type of terminals that are characterized by the attached pistol handle for ease of use. The TSD with a handle often has a long-range barcode reader, operating at a distance of 9 meters and allows you to scan through the glass, which allows employees on the loading technique to read codes without getting off.

Benefits: Ease of use, protection against the external environment, the entire functionality of full-sized TSD.

Disadvantages: price.

TSD with handle

Wearable TSD are attached to the wrist, Leaving the hands with free, and the laser scanner in the shape of a ring is dressed on the finger. Possible voice control. A very convenient device when employees need to have loose hands during scanning.

Benefits: Ease of use, protection against the external environment, the entire functionality of full-size TSD.

Disadvantages: price.

Now for the effective development of business, data collection terminals are actively used (abbreviated - TSD). They are specialized computers of ergonomic design and compact sizes. Devices are used to automate trading, accurate product accounting, control of goods and other processes. They are mainly acquired for warehouses, manufacturing enterprises, outlets. The largest instrument manufacturers are companies like Motorolla (Symbol), Datalogic, Cipherlab, Unitech and Honeywell. In this article, we will describe in detail about the operational purpose of the TSD, about their appearance and the features of the work, how to use the terminals correctly.

Why use TSD?

A specialized computer is able to read bar codes, store and process information according to specified algorithms. As a rule, the data acquisition terminal is equipped with a processor defined by the amount of RAM, a display and a keyboard. The device is also equipped with a scanner that allows you to read bar codes.

TSD operate under the control of various operating systems, for example:

DOS - as a rule, installed on computers equipped with a monochrome screen (text information is displayed);
Windows Mobile - the operating system is put on devices with a touchscreen display, which displays both graphic images and texts;
Palm OS;
Linux.

In the standard configuration, the batteries (batteries) and the communication stand are also supplied together with the terminal. All terminals operate offline. The devices often install professional software, which allows to integrate the device into the commodity system and increase the performance of personnel.

Now you can, restaurant, cafes, pharmacies, food store, hypermarket, enterprises. Modern computers make it possible to effectively solve various tasks:

Devices read product barcodes.
With the help of terminals, you can monitor the price tags.
The devices allow to take products, with high accuracy to control the receipts and movement of various goods inside the warehouse, as well as monitor their expiration and residues. With the help of devices quickly select the desired products on the overhead.
TSD make it possible to carry out inventory, control goods and fixed assets of the enterprise.

Acquaintance with the terminal and its configuration

Before buying a specialized computer, it is important to learn about all the important operational advantages and disadvantages of the selected terminal. It is necessary to understand how to configure it correctly and integrate into an existing accounting system. Usually, additional information about setting up the data collection terminal can be found on thematic sites or forums created by the manufacturer. His representative provides consultations and responds to current issues. Many useful videos are posted on the YouTube resource.

After purchase, as a rule, the drivers are installed and adjust the device. If necessary, the device is connected to the 1C system. If you connect a printer to a computer and install special software on PC, you can print labels.

After setting up the terminal with him, personnel introduce. Employees teach how to properly use the device how to enter information. They are told about the functionality of the TSD.

Features of the scanner: What do you need to know the user?

To read the information, you need to bring a laser beam that emits the scanner on any barcode. The processor recognizes barcode and automatically performs the necessary (programmed) actions. During information transfer, the device makes a characteristic beep indicating that the data is recorded in memory. If for some reason it is not possible to scan code or an error appears, then the data into the terminal is administered using a keyboard or touchscreen. As a rule, the user presses the sensitive color screen using the stylus.

The TSD can be equipped with a Wi-Fi module that opens Internet access or in a local warehouse network, a trading point, restaurant. Almost all modern models function and outdoors, and indoors. Special data collection terminals that are intended for operation in an industrial environment can operate at low temperatures, dust, or high humidity level. Such devices are equipped with a shockproof case, which does not pass inside moisture.

Some models are equipped with a rotating scanning head. With its help, the user's barcode scans at any angle of inclination.

The accounting system data listed in the terminal is transferred in various ways. For example, information can be transmitted via USB, Wi-Fi, Bluetooth, IR port.

Features of design TSD

Functional models are equipped with additional useful buttons. During operation, the user often has to manually enter information (for example, the party number), select the desired item from the list, refuse various actions.
