CH1-OUTPUT-
ON-OFF
DIGITAL
INPUT
Remote-control input for output on/off with a logic signal: a logic-high, will
enable (turn-on) the output of the supply, and a logic-low signal disables (turns
off) the output.

CH1-Remote
Inhibit
Input
Switch/
Relay
Contact
Switch/Relay contact closure or direct short from this terminal to signal return
is required to enable/disable the output of the power supply. Opening the
contact would disable the output. Upon contact closure, if remote inhibit is
selected as live mode, the fault would be cleared, and output could be
enabled from the front panel or by issuing the SCPI command.
If remote inhibit is selected as Latch mode, the output will be disabled, Output
could not be enabled upon the contact closure. Fault should be cleared by
