When this function is enabled, you can trigger the power supply by sending a *TRG or TRIgger
command to the power supply
Remote Inhibit (RI) - Input
Used to turn off the output of the power supply. Can be used to turn off several power supplies simultaneously.

19
The RI input has 3 modes: LATCHING, LIVE and OFF
LATCHING When the TTL signal at the RI port transitions from TTL High to Low, the output of the power
supply will turn off.
LIVE The output state of the power supply changes according to the signal level applied to the RI port.
If the level is TTL high, the power supply output is on; if the level at the RI port is TTL Low,
the output of the power supply is off.
OFF The signal applied to the RI port does not affect the output state of the power supply.
Discrete Fault Interupt (DFI) - Output
NOTE:Available for models 9120A, 9121A, 9122A, 9123A, and 9124A only.
Used to indicate that a fault has occurred in power supply.
The DFI function can be activated by state changes of the QUES, OPER, ESB, RQS bits
QUES: The output level of DFI reflects the state of the QUES bit. When the QUES bit is 1, the DFI output
goes to a low level. When QUES bit is 0, DFI output goes High
OPER: The output level of DFI reflects the state of the OPER bit.
ESB: The output level of DFI reflects the state of the ESB bit.
RQS: The output level of DFI reflects the state of the RQS bit.
OFF: The output level of the DFI port remains high.
KEY LOCK
It is possible to set a password to lock the function keys. After setting the password, all the function keys on the
front panel will be locked except the OUT On/Off key. You must enter the correct password to enable the keys
again. If you don’t want to lock the function keys and you selected the “>KEY LOCK” menu, simply press the
“Enter” key. Do NOT enter any numbers.
When shipped from the factory, no password is set and the function keys are unlocked. The start bit of your
desired password should not be 0.
List Set
This mode allows you to create a sequence of steps, store it into the power supply’s non volatile memory and
execute it. The input parameters for generating a list include the name of the list file, the input steps (no more
