RS-232 Interface Commands

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 58).

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.

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.

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.
