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 Figure 10. 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 Interface Port)
on the Main PCB Control Board in the door (refer to Figure 10) of the Emergency Lighting Inverter Sys-
tem.
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!
