CHAPTER 4    COMMUNICATION INTERFACE 

 

The UPS provides RS-232 and Dry contact protocols in one D-sub 9 connector. 

Using proper UPS management software and cable, the UPS can be managed 

in LAN/ Intranet/ Internet environment. The pin assignment of the D-sub 9 

connector is defined as follows: 

 
 

 

 

 

Figure 4-1 Pin Assignment            Figure 4-2 Open Collector Circuit 

Maximum voltage and current on pin 1, 8 is 30VDC, 10mA.
