Interface Configuration Commands
Refer to also “Configuring the Remote Interface” on page 42
for more information.
SYSTem:INTerface {GPIB|RS232}
Select the remote interface. Only one interface can be
enabled at a time. The GPIB interface is selected when the
power supply is shipped from the factory.
SYSTem:LOCal
Place the power supply in the local mode during RS- 232
operation. All keys on the front panel are fully functional.
SYSTem:REMote
Place the power supply in the remote mode for RS- 232
operation. All keys on the front panel, except the Local key,
are disabled while in the remote mode.
SYSTem:RWLock
Place the power supply in the remote mode for RS- 232
operation. This command is the same as the SYST:REM
command except that all keys on the front panel are
disabled, including the Local key.
<Ctrl-C>
Clear the operation in progress over the RS- 232 interface
and discard any pending output data. This is equivalent to
the IEEE- 488 device clear action over the GPIB interface.
It is very important that you send the SYST:REM command to place the
power supply in the remote mode. Sending or receiving data over the
RS-232 interface when not configured for remote operation can cause
unpredictable results.
