Interface Configuration Commands
Refer to also “Configuring the Remote Interface” on page 66 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
This command places 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 discards 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.
