Chapter 4 Remote Interface Reference

Interface Configuration Commands

See also "Configuring the Remote Interface" in chapter 3 starting on page 46.

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.
