6.4. COMMUNICATIONS INTERFACE

Software interface kits can be used with this Emergency Lighting Inverter System. The RS-232 inter-

face uses a 9-pin female D-sub connector. The information provided to the connector consists of data

about utility, load, and the Emergency Lighting Inverter System. The interface port pins and their func-

tions are identified in the Figure 12. Contact the factory for optional kits supplied or approved by

DSPM. If used, connect the interface cable to the 9-pin computer interface port (RS-232 Standard In-

terface Port) on the Main PCB Control Board in the door (refer to Figure 12) of the Emergency Lighting

Inverter System.

NOTE: Software Interface Kit’s connection is optional. The Emergency Lighting Inverter System works

properly without an optional interface connection. Use only factory supplied or authorized Emergency

Lighting Inverter System monitoring cable!

CAUTION: Use only factory supplied or authorized Emergency Lighting Inverter System monitoring cable!
