SYST:LOC (RS232C, USB and LAN only)
Sets the PAT-T to local mode (Remote Disable; the RMT LED turns off). This is a substitute command for the IEEE488.1 REN (Remote Disable) command. The Remote Disable state enables both panel operations and commands. Use SYST:REM or SYST:RWL to switch to remote mode (Remote Enable; the RMT LED lights).
