I’m looking to hook up a blink marine 8 button key pad, and I want to make sure I’m doing the cam bus correctly. The two can Hi/Lo need to be wired to the cam spot on the PDM 25, do I need to add a resistor inline or does the key pad have one already and the PDM 25 has one and I just need to hook up wires?
thanks
Best practices is a resistor at both ends of your CANbus. If you only have keypad and PdM you’d put one at each end.
PDM25+ has user selectable terminating resistors, all other is need resistors wired. You may be able to get away with one if the bus is short. You also may have other devices like ecu or dash with resistors built in. I find in/out method works best and it is easy to double crimp in DT Socketa
