RS-485 and RS-232 Interfaces
Connection of auxiliary equipment (CAN-Log, PP-01 passenger 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:
For RS-485 and RS-232 interfaces choose the setting:
- “Disabled” – interface is not used
- “Omnicomm LLS” – use to connect Omnicomm LLS fuel level sensors

- “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 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
- “Tachograph VDO” (only in Omnicomm Configurator) – use for Continental tachograph connection
“Frequency of data transmission to server” – select the number of days for the DDD files transmission to the communication server. Possible options: from 1 to 28 days.
“Delete personal data before transmission” – if necessary, enable deleting the driver's personal data prior to data submission to the server.
- “iQFreeze” – use for connection of the refrigerator control device
- “Modbus (Struna +, PMP-201)” – use for connection to the level gauge PMP-201 or the Struna + system
- “TPMS Pressure Pro” (only for RS-232 interface) – use for connection of the tire pressure sensors though TPMS Pressure Pro protocol
- “Truck-TPMS” (only for RS-232 interface) – use for connection of the tire pressure sensors though Truck-TPMS protocol
- “TPMS 6-13” (only for RS-232 interface) – use for connection of the tire pressure sensors though TPMS 6-13 protocol
Fuel Level Sensors
In the “Settings” tab select the “Inputs” section from the list.
In the “Fuel Level Sensors” section:
“Data source” – select the type of fuel level sensors. Possible options:
- “Digital LLS” – when connecting fuel level sensors Omnicomm LLS
LLS-AF” – when connecting fuel level sensor Omnicomm LLS-AF
- “Vehicle sensor” – when connecting the vehicle standard fuel sensor
- “CAN Bus” – when connecting to the CAN bus
- “Struna +” – when connecting to the “Struna +” system
- “PMP-201” – when connecting the level gauge PMP-201
- “Disabled” – in case fuel level control is not required.
When Omnicomm LLS and Omnicomm
“Number of connected sensors” – specify the number of sensors connected to the terminal.
When choosing LLS fuel level sensors connected to a universal input, you need to configure the universal input. For automatic configuration of the universal input in Omnicomm Configurator press the “Configure UI” button.
“Filtration” – enter the size of inner filter. Possible options of filtration:
- “None” – filtration is performed only according to the settings in the Omnicomm LLS sensor
- “Low” – used in case of product installation in stationary fuel storages and non-mobile machinery
- “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
Connection of Omnicomm LLS fuel level sensor should be performed according to the diagram:
Connect Omnicomm LLS fuel level sensor according to the diagram:
Connect several Omnicomm
When connecting the video terminals to the “Struna +” system or the “PMP-201” sensor:
- “Fuel tank volume, L” – enter the fuel tank volume. Possible values: from 0 to 65,000
- “Current fuel volume, L” – displays the current volume according to
the “Struna +” system or the “PMP-201” sensor
Connect the “PMP-201” sensor and the “Struna +” system according to the documentation on these devices. You may connect only one “Struna +” system. The network address, by default, is 80.
Omnicomm LLD Indicator
In the “Settings” tab select the “Auxiliary equipment” section from the list.
In the “Data transmission to Omnicomm LLD indicator” section:
“Data source” – select the data source to display the value on the Omnicomm LLD indicator. Possible options:
- “GPS speed” – displays the vehicle speed
- “Universal input“ – displays the status or values on the terminal universal input depending on the connected auxiliary equipment
- “Engine hours by RPM” – displays vehicle engine hours
When selecting “Engine hours by RPM”, fill in the table of RPM recalculation to engine hours as follows:
In the field “Revolutions per minute” enter the value of RPM, in the field “Factor” enter the value of conversion factor to calculate the engine hours value.
The conversion factors are determined based on the operating conditions of the vehicle. Maximum number of rows – 5.
Engine hours are displayed on the LLD indicator as hour values with a fractional part (1.50 means 1 hour 30 minutes) in the format HH.XX in the range of up to 100 hours and HHH.X in the range of 100.0 to 999.9 engine hours. If the number of engine hours is more than 1000, the last three significant figures are displayed and one symbol after the decimal point.
Engine hours are fully recorded in the terminal and sent to the CS on a continuous accrual basis.
Connect the Continental tachograph to the OKO video terminal via RS-232 and RS-485 interfaces according to the diagram:
Power connections of the terminal and the tachograph must be made similarly: both after the vehicle ground disconnect switch.
When needed, it is recommended to use the RS-232 to RS-485 converter.
To read the DDD files from the Continental tachograph, in Omnicomm Configurator configure the RS-232 or RS-485 interface of the terminal.
