Programming over RS-232-C

Lockout Command

To lockout the front panel controls use the system command LOCK. When this

function is on, all controls (except the power switch) are entirely locked out.

Local control can only be restored by sending the command :SYSTEM:LOCK

OFF.

Restoring Local Control

Cycling the power will also restore local control, but this will also reset certain

RS-232-C states.
