2.5 Communication ports
MX RT
provides 3 communication methods that can be used simultaneously:
◗
2 COM ports provide RS232 or USB communications using EATON SHUT protocol. Compatible with most power
management software applications available into the enclosed
Solution Pac
CD-Rom. Please, note that both ports
cannot be used at the same time.
◗
The output contact port is used for basic signaling or for protection of IT systems like IBM iSeries (formerly AS400)
and more.
◗
The slot is compatible with any EATON communication card (check
www.eaton.com
web site for the complete list
of compatible cards).
Connection to the RS 232 communication port
