3.3 Communication Port Explanation
The UPS is equipped with a true RS-232 communication port as standard to
provide communication with bundled UPS monitoring software for remote
monitoring of the UPS status using a PC.
In addition, there are six optional interface cards available to meet various
communication needs: USB, EPO/ROO, DCE (dry contact relay card), R2E, USE,
and an SNMP/Web card. (Please see Chapter 8.)
The software bundled with the UPS is compatible with many operating systems,
including Windows 98 / Me / NT / 2000 / 2003 / XP / Vista / 2008 / 7 / 8 , Novell,
NetWare, Unix, Linux 2.6.x, Mac OS X v10.5 Leopard, Mac OS X v10.6 Snow
Leopard please contact your local dealer for suitable software.
All communication ports including optional cards can be active and used
simultaneously to monitor the UPS status. However, only one communication
interface at a time (the one with the highest priority) can control the UPS. The
priorities of these communication interfaces are as follows (highest priority first).
1) EPO/ROO input port
2) Optional interface card
3) USB
4) RJ11/RJ45 Communication surge protection
5) RS-232
