3.2 Communication Port

The communication port on the UPS provides for RS-232 communication with the UPS software to remotely monitor the power and UPS
status.
You may use optional interfaces cards for R2E (second RS-232), RSE (RS-485), USE (USB), DCE (Dry Contact), and SNMP. However,
the R2E card, RSE card and USE card must not be used simultaneously.
The software bundled with the UPS is compatible with many operating systems such as Windows 98, 2000, ME, NT and XP. For other
applications such as Novell NetWare, Unix, or Linux please contact your local distributor for a proper solution.
When the optional 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 DCE, R2E, RSE, and USE cards, and then finally the onboard RS-232 port gets the
lowest priority.
