The displayed text can contain digits and letters/characters from the following alphabets:

  • EN, PL, RU, DE, CZ, SK, HU, UA, LT, LV, NO, SE, FR, NL
  • the set of special characters (for example % @ ° $ € < > + – = etc.)


Content, depending on the version of the device, can be transmitted by the following interfaces:

  • Ethernet (two-way communication)
  • RS485 (two-way communication)
  • RS422
  • RS232 (with optical isolation)
  • CL 20mA current loop (with optical isolation)


Displays communicate with the host system using one of the two protocols:

  • MODBUS RTU (RS485 interface only)
  • Simple R004 protocol developed by RGB Technology (included in the price of the device at purchase)

Both interfaces with two-way communication requiring acknowledgment of the receipt of the data by the display.
