  • Position indicator 15*7 dots
  • selectable orientation: horizontal or vertical
  • Standard colour red, optional in green and blue
  • PIC18 microcontroller with internal Flash (32kByte), RAM (1536 Byte) and EEPROM (256 Byte)
  • integrated CAN controller
  • CAN interface with high-speed driver according to ISO11898 with galvanic isolation
  • ICSP interface for In-Circuit-Programming (Software download)
  • 8 inputs and 8 outputs, always 1 input and 1 output onboard connected (lowside switching)
  • Even if always 1 input and 1 output are connected together the may be used for different functions at the same time, because every active output is switched off every 9ms for 3ms (pulsed output) to enable reading of the input in this time. Example: Input used as car call, output used as level indicator.
