2.5 Communication ports

Pulsar MX RT provides 3 communication methods that can be used simultaneously:

◗2 COM ports provide RS232 or USB communications using MGE UPS SYSTEMS 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 MGE UPS SYSTEMS communication card (check www.mgeups.com web site for the complete list of compatible cards).
