Window Protocol
Both RS232 and the RS485 interfaces are available on the 9-pin D-
type serial input/output connector. The communications protocol is
the same (see the structure below), but only the RS485 handles the
address field. Therefore, to enable the RS485, you need to select both
the type of communication and the device address using the front
panel menu or the Navigator software.
