Geotab Support Forum

The attached document can be used to send 3rd party data to the GO unit. The document applies to GO2/GO3 and GO4 units. A separate harness is required that connects to the GO3/GO4 external UART, and provides a RS232 connection. The harness is sold separately. The attached document also includes the schematic for GO3/GO4 units. There is an option in Checkmate under the logging parameters tab to "beep on custom data". When this option is enabled, the unit will beep every time it receives a valid RS232 message. The logging parameters tab can be found by editing a device in the Setup-Devices window.

Once the data is delivered to checkmate, the RS232 data will be stored in the "CustomData" table in the SQL database.

I understand that the data is in the database table "CustomData", but is the custom data available in Checkmate some how?

You can access the data from the "CustomData" table or write an application to interpret the bytes as Checkmate would not know how to interpret it. It will just receive the data from the GO device and store it in the table.

Hello tonypartheniou,is it possible to connect my improvise harness direct to pin connector configuration as per your attachment.

Hello,

We offer an optional RS232 harness for GO2 and GO3/GO4 units. if you have the proper connector, you can create your own harness - however we recommend ordering the optional harness from your local dealer since it is built in a production environment.
