Pin 3 can be configured as a remote inhibit input. The Inhibit In
function lets an external input signal control the output state of all of
the outputs in the mainframe. The input is level-triggered. The signal
latency is 5 microseconds. Pin 8 is common for pin 3.
When an Inhibit signal turns off the outputs, the front panel INH
indicator comes on and the INH bit is set in the Questionable Status
Event register. To re-enable the outputs if the inhibit signal was
latched, you must clear the protection function as explained in
chapter 3.
Outputs can only be controlled by the inhibit signal if they have
previously been turned on by the front panel On key or a remote
command. If an output is turned on while the Inhibit input is true,
the output will remain off.
