RS-232 Interface Commands
Use the front-panel ‘‘I/O Config’’ key to select the baud rate, parity, and the number
of data bits (see chapter 3 ‘‘Remote Interface Configuration’’, starting on
page 46).
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
This command places the power supply in the remote mode for RS-232 operation.
All keys on the front panel, except the ‘‘
Local’’ key, are disabled.
SYSTem:RWLock
This command places 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
This command clears 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.
