2.4. Communication Port Explanation
The Communication port on the UPS provides RS232 protocol to communicate
with UPS software for remote monitoring.
Available optional interfaces cards, which contains R2E (2
(RS485), USE (USB), DCE (Dry Contact), as well as SNMP/ card, can be added
according to need. However, the R2E card, RSE card and USE card cannot be
used simultaneously.
The bundled software of the UPS is compatible with many operating systems
such as Windows 98, & 2000, ME, NT and XP. For other applications like Novell,
NetWare, Unix, Linux, please contact your local distributor.
When the optional interface cards are used together with the onboard RS232 port,
during communication the EPO signals will get the highest priority in control
command, then the SNMP/WEB card, then the shutdown command at the DCE
card, R2E, RSE and USE. Finally the onboard RS232 port will get the lowest
priority.
