3. Connect to the serial devices. You can also connect the serial devices after you finish the configuration.
The GT200-DP-RS is able to connect with RS-485 devices. When using multi-point connection, to prevent
the reflection and obstruction of signal, it’s suggested to connect the terminal resistor (120Ohm, 1/2W)
parallel with the 2 data wires at both end of the network.
