2.4 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 two slots are compatible with any MGE UPS SYSTEMS communication card (check www.mgeups.com web site for
the complete list of compatible cards).
