The GT Series UPS is equipped with a communications interface, providing RS232 and dry 
contact protocols in one sub -D 9-pin female connector located at the rear of the unit. The 

communication port on the UPS can be connected to a computer. This port allows the 
computer to monitor the UPS status and control the operation of the UPS in some conditions. 
Using proper UPS management software and cable, the UPS can be managed in 
LAN/intranet/internet environments.  
Some computers may have a special connector to link this communication port, or require a 
special plug -in card, or need a special UPS monitoring software. For specific information on

The dry contacts (4.3) and (optional) SNMP plug -in card (4.4) can be connected at the same 
time. However, if both are operating simultaneously the remote shutdown facility for the dry 
contacts will not be available. Battery low and AC failure functions remain unaffected. 
 

The pin assignment of the interface connector is defined as follows:
