2.4. Communication Port
2.4.1. The communication port on the UPS provides for USB communication with
the UPS software to remotely monitor the power and UPS status.
2.4.1.1. You may use optional interfaces cards for R2E (RS-232), RSE (RS-485),
USE (second USB), DCE (Dry Contact), and SNMP. However, the R2E
card, RSE card and USE card must not be used simultaneously.
2.4.1.2. The software bundled with the UPS is compatible with many operating
systems such as Windows 2000, XP, Server 2003, VISTA, Server 2008,
Win7 and Win8. For other applications such as Novell NetWare, Unix, or
Linux please contact your local distributor for a proper solution.
2.4.1.3. 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.

2.4.2.1. complies with USB version 1.0,1.5 Mbps
