RS-485 and RS-232 Interfaces

Connection of auxiliary equipment (CAN-Log, PP-01 passenger throughput sensors, DV-1 driver display, JPEG camera, data reception from vehicle J1708 data bus, reception and transmission of navigation data as per NMEA standard) is carried out through RS-485 and RS-232 interfaces. When needed, it is recommended to use the RS-232 to RS-485 converter.

In the “Settings” window open the “Inputs” tab:

Omnicomm Configurator Remote configuration server

For Omnicomm Smart terminal you may only configure interface RS-485.

For RS-485 and RS-232 interfaces choose the setting:

  • “Disabled” – interface is not used
  • “CAN-Log” – connection to a CAN-log device
  • “J1708” – connection to the vehicle J1708 data bus
  • “NMEA reception” – use of navigation data from an external device. If you select this option, you must specify the data port bit rate. “RS port bit rate for NMEA data” – select the data port bit rate for reception of navigation data from an external device
  • “NMEA transmission” – use of the terminal navigation data in an external device
  • “PP-01” – use for connection of the passenger throughput sensor
  • “Camera” – use for the digital camera connection
  • “DV-01” – use for the driver display connection
  • “LLS / LLD” – use for connecting fuel level sensors Omnicomm LLS, Omnicomm LLD indicator
  • “Tachograph VDO” (only in Omnicomm Configurator) – use for Continental tachograph connection

“Frequency of data transfer to the server” – select the number of days for the DDD files transmission to the communication server. Possible options: from 1 to 28 days.

“Remove private data before transmission” - if necessary, enable deleting the driver's personal data prior to data submission to the server.

  • “iQFreeze” (except for Omnicomm Smart) – use for connection of the refrigerator control device
  • “ALM Weight Indicator” – use for connection to the axle load monitoring device
  • “Modbus (Struna +, PMP-201)” – use for connection to the level gauge PMP-201 or the Struna + system
  • “TPMS Pressure Pro” (ony for RS-232 interface) – use for connection of the tire pressure sensors though TPMS Pressure Pro protocol
  • “Truck-TPMS” (ony for RS-232 interface) – use for connection of the tire pressure sensors though Truck-TPMS protocol
  • “TPMS 6-13” (ony for RS-232 interface) – use for connection of the tire pressure sensors though TPMS 6-13 protocol. The terminal transmits temperature data with an interval of 20 degrees: -40,-20, 0, +20,…, +100. The frequency and transmission depend on the energy-saving settings of the wireless pressure sensors configured in accordance with the TPMS user manual.

  • “Medium” – used in case of vehicle's operation in normal road conditions
  • “Strong” – used in case of vehicle's operation in normal and severe road conditions
  • “Maximum” – used in case of vehicle's operation in severe road conditions and when connecting a standard fuel sensor with analog output

When connecting to the “Struna +” system or the “PMP-201” sensor:

  • “Fuel tank volume, L” – enter the fuel tank volume. Possible values: 0 to 65,000
