Remote Mode While in remote mode, use the interface commands to control the output of the Operation power supply from a computer. See Section 3 for a complete list of

device-dependent commands available with this interface.

From remote mode, change to local mode operation by pressing the front panel LOCAL button or by sending either the GTL (Go to Local) command or the REN (Remote Enable) OFF command. You can disable the LOCAL button by using the LLO (Local Lockout) command. For an example of how to use Local Lockout, see “Local Lockout (LLO) Command” on page 30.

To return to remote mode, ensure that the REN command is set to ON and then send any valid device-dependent command. Since the remote mode output settings may be different from the local mode settings, the output is programmed to protect the load by turning off when you toggle from local to remote mode during a session. Check your remote settings and then send OUT ON to restore the output.
