7.3.2 RS232 Port.RS232 and USB Communication options
Figure 7.4 RS232 Pin assignment
To establish a communication link between the UPS and a computer, connect one end of the serial communication cable
that is supplied with the UPS to the RS-232 port on the UPS and the other end to the RS- 232 port on a computer. The
cable pins for the RS-232 communication port are described in Figure 7.4.

Serial Network Management (SNMP) card
Figure 7.5 SNMP connection options
Simple Network Management Protocol (SNMP) is a world-wide, standardised communication protocol that can be used to
monitor any network-connected device via a simple control language and display the results in an application running
within a standard web browser. The SNMP adaptor requires a PC with terminal connections, and least one Ethernet
network connection.
The optional SNMP card fits into the ‘Intelligent Slot’ located on the back of the PowerWave PW3000/TP, as shown in
Figure 7.5. Alternatively, SNMP connectivity can be implemented using an external SNMP adapter connected to the UPS
RS232 output, as shown.
An SNMP/Ethernet adapter contains an RJ-45 connector which allows it to be connected to the network using a standard
network cable. Once connected, the UPS-Management software agent, which is already installed in the SNMP adapter,
then monitors the UPS operating parameters and outputs its data in SNMP format to the connected network. In a multi-
module UPS system the SNMP interface can communicate ‘system-wide’ data or data for an individual UPS module.
SNMP card installation
The UPS does not have to be shutdown before installing a communication card:
1. Remove the two screws that protect the Intelligent Slot of the UPS.
2. Insert the SNMP card into the slot.
3. Secure the SNMP card in position using the screws removed in step 1.
Note:
For more information on the SNMP Cards, see the SNMP User's Manual.
