¶ General Description
¶ Features
The device can display the following information on the Omnicomm ICON display:
- Current date and time;
- Fuel level from LLS sensors (up to 6 sensors);
- Vehicle speed;
- Temperature from 1-Wire sensors;
- Text messages sent to the display via SMS or the Internet.
This feature is supported only on older Omnicomm ICON firmware versions. It has been removed from newer firmware. Please contact the display manufacturer for details.
The device can also receive the following information from the display:
- Driver card ID;
- Driver status changes.
¶ Operating Principles
In an equipment setup consisting of ICON + Device + LLS, the Device is always the master.
¶ Fuel Level, Temperature, and Speed
The ICON display must be configured in Terminal mode. In this mode, ICON does not poll the fuel level sensors itself. Instead, it receives values (0–4095 units) from the device.
The device sends the same fuel level values to the monitoring server as those displayed on the ICON.
To display fuel level in liters correctly, the ICON must have a calibration table loaded for one or more Tanks.
The sensor number configured in ICON must match the sensor number configured in the device.
The sensor number refers to the position of the sensor in the device telemetry and the number under which it is transmitted to the monitoring server.
Do not confuse the sensor number with the sensor network address.
If the calculated fuel level exceeds the maximum value defined by the calibration table, the display will show Err. For example, if the fuel level sensors are disconnected, the device transmits an error code, which is displayed as Err.
If more than two disconnected or faulty fuel level sensors are configured in the device, other displayed parameters (such as speed or temperature) may briefly disappear.
This happens because the device spends additional time repeatedly polling unavailable sensors and cannot update the display quickly enough.
¶ Driver Cards
The device supports only 6-byte driver key/card IDs.
Omnicomm cards use 8-byte card IDs. To ensure compatibility, the device discards the first (leftmost) 2 bytes of the card ID received from the display.
The device transmits the processed card ID to the monitoring server in the same format as a 1-Wire Touch Memory key (for example, in Wialon this is the touch_key parameter).
¶ Text Messages
Text messages are sent from the server to the display using the DV command.
Example Internet command:
*!DV0000 Hello
The display will show the text "Hello".
A detailed description of this command is available in the article "Device Command List".
¶ Driver Status
When transmitting data to the server, the device uses the standard protocol parameter No. 104 - Current Driver Status Received from the Display Module (in Wialon this corresponds to the dm_status parameter).
A description of this parameter is available in the FLEX Protocol Parameter Table.
A link to the table can be found here.
¶ Configuration
¶ Device
On the "RS-232 / RS-485" tab, configure Driver Display and Fuel Level Sensor (LLS).
-
For the display:
- Display Type =
Omnicomm ICON - Network Address = the driver display address configured in the display settings.
- Display Type =
-
For the fuel level sensors:
- Sensor Type =
LLS Compatible - Select the required number of fuel level sensors.
- Sensor Type =
To use temperature sensors, configure the required sensors on the "Temperature Sensors" and "Bluetooth" tabs.
To enable driver card support, configure the "Touch Memory Keys" tab.
If you only need to display the card ID on the display and associate the driver with an object in the monitoring system, you do not need to register the card IDs in the device.
If you want to use output activation based on specific driver cards appearing or disappearing, the card IDs must be registered in the device.
Finally, on the "Protocol Settings" tab, enable the required protocol fields:
- For fuel level sensors
- For temperature sensors
- For driver status
¶ Display
Open the configurator, connect the display, and select Indicator as the device type.
For detailed information about the display features and configuration, refer to the manufacturer's documentation:
https://doc.omnicomm.ru/ru/omnicomm_icon-manual/settingThis article provides a quick-start configuration example for use with Navtelecom devices.
Select Terminal as the connection type.
Set the ICON network address to the same value that was configured in the device.
To display fuel level information, create one or more Tanks by clicking Add Tank.
After creating the tanks, assign the configured sensors to them using the calibration tables. Click Calibration Tables.
After configuring the tanks and calibration tables, configure the display layout, for example as shown below.
When configuration is complete, write the configuration to the display.
