This guide covers how to configure the G120 or Remora2 so that it can read temperature readings transmitted by the SensorNode Bluetooth.
Getting Set Up
- Please review the Getting Started - SensorNode Bluetooth article on our knowledge base
- Please review the Updating firmware and updating Bluetooth firmware articles on our knowledge base
OEM Server System Parameters
Navigate to oemserver.com/Device and search for your device. Then select the device checkbox on the left and click 'Parameters' >> Edit System parameters (single device)
The first parameter tab you'll need to enable is the Bluetooth Global Settings. Simple change this value to Yes to enable Bluetooth Scanning on your device.
The next parameter tab you'll need to enabled is a tag scanning parameter tab. For the Remora 2, this is the "BLE Tag Scanning" paramter tab, and for the G120 this is either the "BLE Periodic Scanning" or "BLE Continuous Scanning". These parameters control when and for how long the device scans for.
Note: The SensorNode will send a Bluetooth 'beacon' every 2 seconds, containing data it's inputs (I2C, Analogue, Digital Inputs)
The BLE SensorNode 1 tab includes the following parameters:
Note: you can pair two SensorNodes to each Device with tab 1 and tab 2
- Serial Number: Insert the six digit serial number of the SensorNode here
- Enable Logging: YES or NO. Set to yes if you want the device to scan for the sensor node.
- Upload on log (continuous scans only): YES or NO.
- Log Interval (continuous scans only): This is the period between sensor reading logs in a continuous scan.
- Battery Analogue: select a Digital Input to write the voltage to
- Temperature Probe 1 Analogue: (Default value is Analogue 8)
- Temperature Probe 2 Analogue: (Default value is Analogue 9)
Up to 2 DM Temperature Probes can be connected to each SensorNode Bluetooth - as per this wiring guide: Falcon - Wiring In Sensors (the wiring is the same for both devices)
In the above example - the temperature value will be logged and uploaded by the device every hour while out of trip, while in trip the these values will be logged every 5 minutes.
Displaying Temperature Data in Telematics Guru
Once you have set up the OEM Server parameters and wired in your sensors, you can start viewing the data collected in Telematics Guru.
1) Create an I/O Mapping for the sensor value
Go to Manage Assets >> Edit >> I/O Mappings and click Add
2) Once you pick the Analogue number as per your OEM Server parameters you can set up the measurement configuration. There are a selection of preset Types available, or you can use a general number and conversion,
Note: if your number appears in Telemetry IO as an incorrect value, e.g. 250.0%, try changing the Conversion factor, this will change the converted figure in Telemetry IO but not the raw data in Telemetry.
3) Save, here you can also select whether the readings will appear in Trip view and Live view.
4) Navigate to Assets >> Telemetry I/O and you can see the final converted readings. You can also graph the analogue values for custom time periods by going to Reports >> Fleet Reports >> Asset Analogue Graph.
