AZD-AD 84:RS-485 communication error

Post by ernesto.martinez » Wed Sep 23, 2020 2:37 pm

Hello,
I am trying to communicate with a controller AZD-AD using RS-485 communication, but I am getting the error code 84.
I am attaching the cable pinout.

I am configuring the COM6 (BAUD 19200, DATA BITS 8, PARITY EVEN, STOP BITS ONE, HANDSHAKE NONE)

This is the frame:
serialPort1.Write("0106 007D 0008 1814")

Hope somebody can help me.
