Canbus stream not sending voltage values



I have a project that im working on that im looking to stream all of the voltages from the inputs directly to another canbus device and it looks like nothing is coming in on the input #6 and 7 which are setup as temperature sensors (and are at 2.3v in the first input picture) Kvaser on the same bus is capturing that 00xx data is coming through even though there is definitely voltages on this input. This specifically seems to only affect the inputs, the outputs do output the proper voltage all the way down to 0v atleast on the HS, not sure about the LS. This isnt a major issue on this project, just wanted to bring it up to the developer for fixing in the future.

PDM25 V1 CAN Stream

I have a PDM25 V1 and a PDM25 V2.


The V2 exposes the hardwire can stream contents in the configurator and I'm good with that, but the V1 doesn't.


I hoped that, by ticking the enable stream checkbox and selecting the Hardwire option, it would output a similar stream.


That doesn't seem to be the case and you can't load a config file in either.


I've looked at the hwpdm file (JSON) in the hope that I could just paste in the file from the V2, but the properties are different.


Also, the v2 stream uses 40 frames, which would use all of the available frames in the V1, which isn't ideal.

PDM25v2 FW 1.3.0 CAN IMU output

I would like to stream IMU angle over CAN with my PDM25v2 on FW1.3.0. I have enable the can stream and is able to monitor the CAN message coming out. What I am concerned about is that all the value for angles are exactly zero while variable monitor is showing small angle of +-0.05 so I would expect to see some values in the CAN stream. The module is already mounted so tilting it to check might be harder to do so I would like to check if I am missing anything before diving more. Additional information is that the IMU is shown to be uncalibrated in the IMU tab so I'm not sure if that would gate the CAN output although it is showing on variable monitor. If IMU needs calibration, what is the process as I do not see the necessary GUI element for calibrating the IMU.

pdm can issue

i have a pdm15 was working just fine and now it won't work at all. keypad turns on but when buttons are pressed nothing happens. Dash turns on, windows work. no keypad functions work. firmware wont update and can't program. keypad and dash are very slow to turn on as well. Takes a lot longer than it used to for it to wake up. nothing has changed.

Hi, Please send your config to contact@hardwire-electronics.co.uk It sounds like a CAN bus issue. check the CAN wiring and check the termination resistors.
