N4DIG08 FAQ
N4DIG08 I tried it with "Modbus Poll". The communication works - see screenshot below. But I cannot change the output. It always stays at 5V (high) no matter what I send.
Same is true for the input - they read 0 but are all 5V (high).
Can you please help me?
Answer
N4DIG08 is in input mode by default.
1 Please short the M0 jumper to change to output mode.
2 Operate according to the instructions in the document "N4DIG08 Modbus RTU Protocol (8 Output)". The OPEN instruction is 0X0100, and the CLOSE instruction is 0X0200
Question
one more question: is it possible to change the output behaviour at power-up? Currently the outputs are high by default when I power-up the device.
Can this be changed?
