essb00 Posted October 2, 2023 Report Share Posted October 2, 2023 Hi... First time setting up ECUMaster CAN Switch Board V3. I just finished all the soldering and have tried to connect and test. All 8 CAN Analog Inputs and all 8 CAN Digital Inputs have been tested working. However, all 4 CAN Auxes do not work -- they constantly read +12V even with the CAN Aux Tests. Did I miss anything?

koracing Posted October 2, 2023 Report Share Posted October 2, 2023 Try chaning from Transmit User Stream 1 to Transmit User Stream 4 on Channel 4. Quote Link to comment Share on other sites More sharing options...

Now it is constant 0V on all 4 of them even with 'Test'. Quote Link to comment Share on other sites More sharing options...
essb00 Posted October 3, 2023 Author Report Share Posted October 3, 2023 CAN Aux 1 works as it should with this setup - has 'High' at inactive state, 'Low' in active state, ....but not CAN Aux 2, 3, 4 (inactive states are in 'Low' --- quite complicated, more described below). Some combinations I've tried and the outcomes: CAN Aux 2, 3, 4 (inactive states are in 'Low') Whenever CAN Aux 2 'Test' is turned to 'On", CAN Aux 3 turns 'High'. Whenever CAN Aux 3 'Test' is turned to 'On', CAN Aux 4 turns 'High' --- and CAN Aux 3 turns 'Low' (when is already on 'High'). Whenever CAN Aux 4 'Test' is turned to 'On', CAN Aux 3 turns 'Low' (when is already on 'High') Confusing, isn't it? Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 3, 2023 Report Share Posted October 3, 2023 Put stream 4 back to MS byte order, you can see in the visual frame at the bottom of your setup screen all the start positions are now messed up. The stream was set up correctly before, all you needed to change was channel 4 to transmit user stream 4 as Kris suggested. If it didnt work like that then your problem is elsewhere. I would turn off the OBD2 also while you are testing. Quote Link to comment Share on other sites More sharing options...
essb00 Posted October 3, 2023 Author Report Share Posted October 3, 2023 Have put Transmit Stream 4 from the stream template, have turned off OBD2, and the OBD2 device disconnected. Again, all 4 CAN Auxes not working. Quote Link to comment Share on other sites More sharing options...

Adamw Posted October 4, 2023 Report Share Posted October 4, 2023 You dont have CAN Aux 1-4 assigned to anything in your map so they will be outputting a "2" via CAN. When you set it to test they will be outputting a 1. So most likely the ECU master device considers anything >0 to be "on", so you wont see any difference between the two states that the ecu is sending and the switchboard wont handle "Off" or "Fault" statuses correctly. If you actually assign CAN aux 1-4 to the function you want to use them for then the inactive/active states will at least work correctly.

After I assigned a function and did the test from there, all 4 CAN Auxiliaries worked as they should. Thanks! Quote Link to comment Share on other sites More sharing options...
