Communication Options
The UPS has serial communication capabilities through the USB and
RS-232 communication ports or through a connectivity card in the
available communication bay. The UPS supports two serial
communication devices according to the following table:
NOTE
：
The communication speed of the RS232 port is fixed at 2400
bps.
RS-232 and USB Communication Ports
To establish communication between the UPS and a computer,
connect your computer to one of the UPS communication ports
using an appropriate communication cable (not supplied). See
Figure 20, 21 for the communication port locations.
When the communication cable is installed, power management
software can exchange data with the UPS. The software polls the UPS
for detailed information on the status of the power environment. If a
power emergency occurs, the software initiates the saving of all data
and an orderly shutdown of the equipment. The cable pins for the
RS-232 communication port are identified in Figure 22 and the pin
functions are described in Table 9.
