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 |
