OUTPut?
This query returns the output state of the power supply. The
returned value is 0 (OFF) or 1 (ON).
OUTPut:RELay {OFF|ON}
This command sets the state of two TTL signals on the
RS- 232 connector. These signals are intended for use with
an external relay and relay driver. The TTL output is
available on the RS- 232 connector pin 1 and pin 9. When
the OUTPut:RELay state is ON, the TTL output of pin 1 is
high (4.5 V) and pin 9 is low (0.5 V). The levels are reversed
when the OUTPut:RELay state is OFF. At *RST, the
OUTPut:RELay state is OFF.
TTL output of pin 1 or pin 9 of the RS- 232 connector is
available only after installing two jumpers inside the power
supply. Refer to the Service Guide for more information.

Do not use the RS-232 interface if you have configured the power supply to
output relay control signals. Internal components on the RS-232 circuitry
may be damaged.
