previous operating state.
From the remote interface:
To select the Inhibit function:
DIG:PIN3:FUNC INH
To select the pin polarity:
DIG:PIN3:POL POS
DIG:PIN3:POL NEG
To set Inhibit mode to Latching:
OUTP:INH:MODE LATC
To set Inhibit mode to Live:

Fault/inhibit system protection
The following figure illustrates some ways that you can connect the Fault/Inhibit pins of the connector.
As shown in the figure, when the Fault outputs and Inhibit inputs of several instruments are daisy-chained, an
internal fault condition in one of the units will disable all load inputs without intervention by either the controller or
external circuitry. Note that when using the Fault/Inhibit signals in this manner, both signals must be set to the
same polarity.
