Here are the Default I/O Mappings for the Barra range of devices:

  • Barra Core
  • Barra Edge
  • Barra GPS 

You can change some of these mappings on Device Manager however, our default settings have been designed to prevent the need for making changes. 

This mapping can be very handy to identify and debug issues, and when integrating the device data. 

For example, if the device is connecting to the server/platform intermittently, this may be a coverage issue which can be confirmed by analyzing/plotting Analogue 4 (Cellular Signal Strength).

Analogue Mapping Description
1 Battery Voltage
3 Temperature
4 Cellular Signal Strength
5 Loaded Voltage
Digital Mapping Description
0 Ignition
1 'Battery Good' Flag
1 = Good
0 = Low
2 'Battery Critical' Flag
1 = Critical

For information on the battery flags, see Battery Level Monitoring.

All Digital Matter devices have 'status flags'. The status flags are sent in Field 2 to 3rd party servers. However, in Telematics Guru, they are remapped to the following Digital Inputs. 

Digital Mapping Description
24 Trip State
1 = in trip
25  Battery Good
1 = good
0 = low
29 Battery Critical
1 = critical
