Interface Configuration Commands
See also "Configuring the Remote Interface" in chapter 3 starting on page 50.
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.
