Auxiliary User Lines connector, located on the
rear panel, provides several signals to increase your operating control of
the supply. These signals are dependent on the operator's design and uses.
The operation of the user lines connector signal requires that you provide
external Vcc and ground. Use a standard 8-position telephone jack and
data cable to connect to the user lines connector. To locate the connector,
refer to the Ethernet/RS-232 Interface
