What to do if Apollo Computer Hardware controller cannot communicate with the programming host?
If the Apollo Computer Hardware controller cannot communicate with the programming host, verify the RS-485 or network communication. Also, observe the port activity LED (D15); it should blink when communication is active. Try to ping the device from the host to see if the network has been configured correctly.
