Control Interface Details
Control Cable Connections
There are two high-density (three-row) DB15 connectors located on the rear panel of the UPS:
The User I/O female DB15 connector on the left is for an optional connection to a host/system
computer so that it can control the UPS and receive information regarding the status of the UPS.
The Configuration male DB15 connector on the right is for a connection between SynQor UPS
units in standard and expanded paralleling configurations. The port is used in conjunction with
the paralleling CONFIGURATION cables to exchange load sharing information and coordinate
startup/shutdown operations between parallel UPS units.
The designation/location of the pins for the User I/O female high-density DB15 connector are
