Communicaon Port
The communicaon port on the UPS provides for RS-232 communicaon with the UPS soware to remotely moni-
tor the power and UPS status.
You may use oponal interface cards for Relay (Dry Contact) and SNMP. These cards may be used simultaneously.
The soware bundled with the UPS is compable with many operang systems such as Windows 98, 2000, ME,
NT and XP. For other applicaons such as Novell NetWare, Unix, or Linux please contact your local distributor for
a proper soluon.
When the oponal interface cards are used together with the onboard RS-232 port the EPO signals will get highest
priority, then the SNMP/WEB card, then the shutdown command at the relay card, and then nally the onboard
RS-232 port gets the lowest priority.
