4.9 Remote Inhibit Function
The remote inhibit input available on the high density D-sub 15 connector at the rear panel can be
used to disable the output of the AC source. This input takes either a low level TTL signal or a contact
closure. The mode of operation can be programmed over the remote control interface using the
OUTP:RI:MODE command. See 6005-961 programming manual for details.
The following modes are supported.
MODE
OPERATION
LATCHING
A TTL low at the RI input latches the output in the
protection shutdown state, which can only be cleared
by an OUTPut:PROTection:CLEar command or by
manually resetting the output.
LIVE
The output state follows the state of the RI input. A TTL
low at the RI input turns the output off; a TTL high turns
the output on. This mode is equivalent to using the
Output On/Off button on the front panel.
Default mode. This mode is active at power up.
OFF
The instrument ignores the RI input.
Table 4-4: Remote Inhibit Modes.
The RI output state is saved as part of an instrument setup using the REGISTERS menu. It can be
made part of the power on setting if needed. The default state is LIVE.
