Motec C185 Integration Troubles
Posted: Tue Mar 12, 2019 5:58 pm
I hope all is well.
I am attempting to integrate an AnalogX with a Motec C185 Dash on hand. Any insight or direction would be greatly appreciated. I believe I have a comms setup issue on hand. The "received" can data values are fixed and unrealistic voltages(all 4 inputs are different) and do not vary even if I disconnect the 6 pin connector removing all the analog sensors from the equation. These values are not the default values set by the Motec software ie. in case a sensor is missing. The defaults are all set to zero. No can-bus errors are present in the Motec. I have included a URL to pdf containing screenshots of Motec settings.
Hardware Checks Performed:
-Motec Hardware/loom in proper working order, confirmed by using can bus channel to receive IR Temp can data
-AnalogX Baud rate set to 1M (jumper removed and verified the bridge is open with a multimeter)
-AnalogX default termination is intact
-12v supply at AnalogX w/ good ground
-5v reference out of AnalogX
-With 6pin connector discounted 0.2v at signal pins 1-4 (using grd at 6pin)
-6pin connected, measure at 6pin, each analog pin sensor voltage is appropriate (ie manually referencing to sensor calibration curves each is within reason)
Programming Checks:
-Motec Communications setup Mode: "CAN"
-Motec Communication setup Parameters: "receive message", "fixed binary", "Wordswap"(tried "normal"), "receive timeout"=2200ms, "Extended Address"=000E4600
-Motec Channel Settings: Input1=offset 0, length 2...Input2=offset 2, length 2...Input3=offset 4, length 2...Input4=offset 6, length 2.
-Motec settings: multiplier=1, divisor=1, adder=0, (note changing these settings does change the displayed channel data but the data is still fixed and unrealistic voltages, no change with analog sensors connected/disconnected.[/b]
