STX 2000

Industrial RFID reader

RFID reader for vehicle weighing system

  • Clear display showing messages for a driver
  • Numeric pad and RFID display
  • 4 digital inputs, 4 digital outputs to control external devices (e.g. traffic lights, traffic gates)
  • Transmission protocol allowing to, among others: read a particular RFID number, read the keypad, control texts displayed on the display, display bitmaps, identify the current state of digital inputs, control digital outputs, control the additional serial port, e.g. to operate an external display, a printer or a scale meter
  • The RFID transponder read-out is signalled by a beep
  • Serial port allowing to connect an additional device (e.g. scales, a LED display, a serial printer)
  • Robust casing made of aluminium
  • Integrated heating diodes to allow for operation in sub-zero conditions

An example weighing system with STX 2000

WEIGHING SYSTEM WITH STX 2000

The system includes:

  • GSW Automat software
  • 2 x STX-2000 reader

Weighing operation schedule:

  1. A vehicle enters the weighbridge.
  2. A driver put RFID card on STX-2000.
  3. The system checks data. Upon successful verification, the display shows the vehicle’s registration number and a product assigned to the card.
  4. The driver can change on the keypad the number of the product being weighed.
  5. Upon stabilisation, the weighing result is saved in database.
  6. The reader displays “OK” which means that weighing operation has been successfully completed.

Comparison of STX readers

Advantages of the STX 2000 reader

The reader is located in an aluminium box of 160x100x80 mm. The reader allows to display any words on the screen (Unicode) as well as bitmaps. It is possible to control digital outputs. It is possible to read the state of the digital inputs, the state of the RFID transponder or the condition of the device. The sound level and the brightness of the "OK" sign can be adjusted by the user. It is possible to control an additional serial port, e.g. to operate an external display, printer or weighing metre.

1. CLEAR GRAPHIC DISPLAY
2. ALPHANUMERIC KEYPAD TO LOG IN BY MEANS OF A PIN CODE AND/OR TO SELECT A VEHICLE TO BE WEIGHED UP
3. A BEEP SIGNALS THE READING-OUT OF THE RFID TRANSPONDER
4. ADDITIONAL SERIAL PORT, AVAILABLE ON THE EXTENSION CARD, TO CONTROL, E.G. AN EXTERNAL LED DISPLAY
5. RS232/RS 485 2W WITH 2 KV OPTOISOLATION, 6 DIGITAL INPUTS, 4 DIGITAL OUTPUTS
6. ROBUST CASING MADE OF ALUMINIUM

Software

Readers of STX series natively co-operate with the software created by our company. However, it is possible to purchase only the readers – in such a case we make the reader’s communication protocol available.
