CAN Messages Received from Device- DBC v1.7

A DBC file for the below messages can be obtained by emailing support@cntrl.io

• TLM_Suppress_Transmit

  • This message allows the logger to suppress the transmission of data, typically to reduce telemetry running costs and provide certainty over data allocations. It is recommended to use a maths channel to allow some transmission when your transmission condition is not met, for example to transmit for 2 seconds and suppress for 18 seconds. This allows engineering team to validate that telemetry is primed and ready before the telemetry is required whilst saving 90% of data being transmitted. Control can provide sample maths channels if required.

• TLM_TargetIP

  • This message allows the logger to determine which of the target IP addresses in the modem is used for data transmission, using this message data can be sent to an alternate target, for example a backup VPN on a hot spare telemetry server or a receive modem instantly. It is also possible to send data to both primary and secondary targets at the same time however it should be noted that this will double the amount of data used by the modem during transmission.

• TLM_Transmit_Mode

  • This message allows the modem to control the transmission mode of the modem, it could for example be used to switch modes based on a driver rotary switch, or to dynamically switch between transmit modes based upon lap distance or other logger channel.

• TLM_TelemIO

  • This message allows the modem to control the IO mode of the modem (to switch between ethernet and serial telemetry), it could for example be used to switch modes based on a driver rotary switch, or to dynamically switch between transmit modes based upon lap distance or other logger channel.
