I’m using a National Control Devices ProXR_USB relay board and I’m having trouble receiving a response.
I’m able to control the relays but I’m not having much luck with receiving reply’s from the board, Vee errors out -118.
Control
If i send bytes 170 2 254 108 1 24 the relay i want closes so I know im talking to the board
Responding
If i send the bytes to request the a/d status, then set a read command i Vee errors out.
If I send bytes 170 2 254 166 80
Expected reply is 170 8 255 255 255 255 255 255 255 255 170
Can someone give me a little guidance?
