Well, here I am again, what is this the third time? I last took this up in the blog Nexgen: CANaerospace: RSS: C-3436A Radio: Build i. So this is part II of the build, covering the hardware, 2x RS232 cutouts, securing the CAN interface, as well as the relay for the panel lights. I will also wire the DIN-5 power connector to the rear of the unit.
Also, please note below the new wiring guide!
After that, I will have to test the Radio Head with the Slave. The output frequency will be converted into two 4-bytes with an additional two bits in the LSB for power and lights. , so I have to get creative on how to compose the message:
