2.5 Communication ports

 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).
