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 “Remote Interface Configuration” on page 79).
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.
NOTE
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.
