RS-485 interface

By default, the interface is laid out as RS422 full duplex interface.

By connecting RX and TX lines the interface can be used as RS-485 bus interface. This can be done at the screw terminal or with the solder bridges (“Duplex”) on the back of ZSOM-Control.

To add a 120Om termination resistor between the data lines mount the Jumper (“Termination”).
