Interface Module Overview The DH-485/RS-232C Interface Module, catalog number 1747-KE, is a
communications interface module that acts as a bridge between
DH-485 networks and devices requiring DF1 protocol. The DF1 port
on the interface module can be configured for RS-232/423, RS-422, or
RS-485 devices. Residing in an SLC 500 chassis, the module is ideally
used as an interface module, linking remote DH-485 networks via a
modem to a central host.
