Communication Port Explanation
The Communication port on the UPS provides true RS232 type to
communicate with UPS software to remote monitoring the power and UPS status.
With optional interfaces cards, which contains R2E(2
nd
RS232), RSE(RS485),
USE(USB), DCE(Dry Contact), as well as SNMP/ card, you may combine them
according to your demand. However, the R2E card, RSE card and USE card are
prohibited to 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 for a proper solution.
When the optional interface cards are used together with onboard RS232 port
in 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 & also
R2E, RSE and USE, then onboard RS232 port get the lowest priority.
