SYST:REN (PLZ-4W only) (RS232C and USB only)
Sets the PLZ-4W operation to remote mode. All panel keys except the LOCAL key are locked. This is a substitute command for the IEEE488.1 REN message (Remote Enable) and address designation.
SYST:GTL is used to return to local mode.
The power-on default is ON for the RS232C and OFF for the USB. Omitting the parameter is equivalent to ON (1).
