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 two slots are compatible with any EATON communication card (check www.eaton.com web site for the
complete list of compatible cards).
