RS-232 Interface Commands
Use the front-panel “I/O configuration” key to select the baud rate, parity,
and the number of data bits (See chapter 3 “Remote Interface Configuration”, starting
on page 50).
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 SYSTem:REMote 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 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 SYSTem:REMote 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.
