8. COMMUNICATION INTERFACE
The UPS provides RS-232 protocols in one D-sub 9 connector. Using proper
UPS management software and cable, the UPS can be managed over
LAN/intranet/internet environment.
UPS can be also managed through IE / network management software when
it’s installed an external SNMP card .The detail install method reference to
the“SNMP card user’s manual”
The pin assignment of the D-sub 9 connector is defined as follows:
8-1 RS-232
Pin 2 : PC receives line
RS-232
data from UPS.
Pin 3 : PC transmits line RS-232 data to UPS.
Pin 5 : Signal ground.
Pin 7 : Reversed for plug and play function.
The
RS-232
communication port provides the following functions:
1) Monitoring charger status
2) Monitoring battery status and condition
3) Monitoring inverter status
4) Monitoring UPS status
5) Monitoring the utility status
6) Providing the power switch function for computer to turn on/off the utility
on schedule for power saving
7) Adjustable Transfer voltage
The UPS data is provided at 2400 bps baud rate and made up of 8-bit, 1
stop-bit and no parity bit. All information is encoded in ASCII format.
HARDWARE:
- BAUD RATE--------------2400 bps - DATA LENGTH----------8 bits
