M800 To CDL3 CAN Communication Not Established
Posted: Sun Apr 14, 2024 6:13 am
For our Formula SAE race car, we have an M800 ecu, PDM15 power distribution module, and a CDL3 dashboard set up within a working CAN network with terminating resistors on both ends.
We have a successful CAN communication established from the M800 to PDM15 via a template (280 Decimal / 0x118 Hex) but cannot successfully establish a CAN communication from the M800 to the CDL3.
There is a working M800 data set template (front brakes, rear brakes, engine temp, oil pressure) exported to the PDM15 successfully.
Our current M800 (Transmit) --> PDM15 (Receive) connection is as follows :
Parameter Value
CAN 0 Data 8
CAN 0 Address 280
CAN 0 Trans Rate 50
Device Data Size CAN Address Offset
Front Brake Pressure (psi divided by 100) "16bit (signed) " 118 hex Byte 0
Rear Brake Pressue (psi divided by 100) "16bit (signed) " 118 hex Byte 2
Engine Temp (degC) "16bit (signed) " 118 hex Byte 4
CDL Brake Pressure (psi divided by 10) "16bit (signed) " 119 hex Byte 0
I keep getting conflicting directions on what to do to establish CAN communication from the M800 to the CDL3. The old Youtube video for the older version ADL dashboard states to export a template (520 Decimal / 5F0 Hex) from the M800 to the CDL3 but this does not work and also knocks out the M800 to PDM15 CAN communication and it needs to be re-established.
We would like to establish the following M800 inputs to be transmitted to the CDL3 dashboard for display:
Engine Temp (degC)
Engine RPM
Gear Position
Oil Pressure
Oil Temp
Attached are the configuration summaries for the PDM15 and the CDL3 devices. In addition the default M800 CAN Data Set Up screenshots are available just in case.

It would be much appreciated if someone would please advise ASAP if possible. My contact email is makpe@ltu.edu.
