VRS Terminal

The VRS Terminal was developed for diagnostics and control of automated industrial machines that can be operated with specialized terminal equipment in case of failures. Such terminal equipment is usually expensive, hard to replace, difficult to use and carry and completely incomparable to modern technology we carry in our pockets today

The VRS Terminal replaces currently used terminal equipment with two devices: a com­mu­ni­ca­tion module that enables connectivity between the machine we want to control and a mobile phone or tablet computer with the VRS Terminal software.

The VRS Terminal is and Android application that translates messages and signals between an Android device and the industrial machine we want to diagnose or control.

Depending on the com­mu­ni­ca­tion port (type and connector), a generic Bluetooth serial adapter can be used as the com­mu­ni­ca­tion module to connect the industrial machine and the mobile device running VRS Terminal. If a generic Bluetooth adapter can not be used, the KoMnA com­mu­ni­ca­tion module is used. The KoMnA com­mu­ni­ca­tion module is developed for use in industrial conditions: it offers a wide range of options regarding connectors, power source, mounting and environment conditions.

The combination of an Android mobile device and Bluetooth com­mu­ni­ca­tion was used to achieve a wide range of possibilities regarding the available hardware solutions on the market. An Android mobile device enables the use of mobile phones already used by the service crews. Considering that a failure rarely happens in an area that is easily accessible, that allows a lot of movement (hight or narrow corridors) or use of large, heavy and clumsy equipment, a mobile phone with Bluetooth connectivity can be considered a better option than a com­mu­ni­ca­tion cable. Also, Bluetooth com­mu­ni­ca­tion is standard for all Android devices with a Bluetooth module, while cable com­mu­ni­ca­tion is not.

VRS Terminal software

System requi­re­ments for the VRS Terminal are Android 4.0 or higher, screen resolution of at least 800x480, Bluetooth 2.1. and 200MB of free space.

The cha­rac­te­ris­tics of the VRS Terminal software are:

  • runs on a wide range of Android devices,
  • connectivity with any Bluetooth device compatible with the SPP standard,
  • support for different com­mu­ni­ca­tion profiles for different machines,
  • emulation of a physical keyboard with an adjustable key repeat rate,
  • custom keyboard layout and number of keys on the keyboard,
  • adjustable keyboard and screen size,
  • adjustable screen orientation (landscape or portrait),
  • adjustable keyboard position (top/bottom),
  • option to record all com­mu­ni­ca­tion between the controlled machine and the mobile device on the device,
  • recording extensive logs for diagnostic purposes.


The VRS Terminal is typically used in two ways:

On locations where we want to control multiple identical machines that have few failures and are easily accessible, a portable com­mu­ni­ca­tion module is used. The module is in a small housing with a magnetic side and a short com­mu­ni­ca­tion cable. The module is attached to the machine with the magnet and connected with the com­mu­ni­ca­tion cable. The machine is then switched to manual ope­ra­tion. The maintenance crew connects to the machine with the mobile device trough the VRS Terminal.

On locations where the machines we want to control require frequent interactions or are not easily accessible, the com­mu­ni­ca­tion module is fixed to the machine. The most optimal localtion and housing is used for the module, so that the movement of the machine is not obstructed in any way and the easiest and best connectivity with the mobile device is assured.

Since mobile screens can be small to use, the use of a 7" tablet computer is recommended. We recommend a rugged tablet computer or at least the use of a good screen protector and case (such as BobjGear).

KoMnA com­mu­ni­ca­tion module

The com­mu­ni­ca­tion module was developed for use in industrial conditions. The Bluetooth connectivity enables com­mu­ni­ca­tion with an Android device and other Bluetooth enabled devices. A PC can be used for analysis and diagnostics of a problematic industrial machine from a safe distance, together with other diagnostic software.

The com­mu­ni­ca­tion module is customizable and enables:

  • Bluetooth 2.1, 3.0, 4.0 com­mu­ni­ca­tion,

  • replacing Bluetooth with WiFi or ZigBee com­mu­ni­ca­tion,

  • connectivity with RS-232, RS-422 or RS-485,
  • 9 - 30 VDC,
  • adjustable connection cable (length and connector),
  • powered trough the connection cable or by a separate source,
  • custom size of housing and method of attachment (screws, holders, magnet).


Verify all routes are free of obstacles before use. Verify you or anyone else is not in danger in case of sudden and unexpected moves of the controlled machine. When using the terminal equipment you must be standing on the location, designated for use of the terminal. Usage of the terminal equipment outside of designated locations is not recommended, since com­mu­ni­ca­tion errors can occur that can cause sudden and unexpected moves of the controlled machine.


Some major facilities that use VRS Terminal:

  • Lek d.d., Prevalje (automated VNA ware­house for raw materials),
  • Steklarna Hrastnik d.d., Hrastnik (automated VNA ware­house for finished and semi-finished goods).

VRS Terminal is aslo compatible with the automated lifts and trucks at the following locations:

  • AERO Celje (automated VNA ware­house for paper rolls),
  • Iskraemeco (automated VNA ware­house of finished goods and repro material),
  • KRKA Novo mesto (automated VNA ware­house for packaging),
  • Merkur (Lesnina) Ljubljana (automated VNA ware­house for furniture),
  • LIV Postojna (automated VNA ware­house for finished and semi-finished goods).

and other systems based on GESPAC, BINAR and SIEMENS computer systems.
