Communication Port Explanation
The UPS is equipped with a USB communication port as standard to provide communication with bundled
UPS monitoring software for remote monitoring of the UPS status using a PC.
You may use optional interfaces cards for R2E (RS-232), RSE (RS-485), USE (second USB), DCE (Dry Con-
tact), and SNMP. However, the R2E card, RSE card and USE card cannot be used simultaneously.
When the optional interface cards are used together with the onboard USB 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 USB port gets the lowest priority.
