Reference Manual
8-336 2461-901-01 A/November 2015
Details
The tspnet.write() function sends inputString to the remote instrument. It does not wait for
command completion on the remote instrument.
The Model 2461 sends inputString to the remote instrument exactly as indicated. The
inputString must contain any necessary new lines, termination, or other syntax elements needed
to complete properly.
Because tspnet.write() does not process output from the remote instrument, do not send
commands that generate too much output without processing the output. This command can stop
executing if there is too much unprocessed output from previous commands.
Example
tspnet.write(myID, "runscript()\r\n")
Commands the remote instrument to execute
a command or script named runscript() on
a remote device identified in the system as
myID
.

upgrade.previous()
Details
This function allows you to revert to an earlier version of the firmware.
When you send this function, the instrument searches the USB flash drive that is inserted in the
front-panel USB port for an upgrade file. If the file is found, the instrument performs the upgrade. An
error is returned if an upgrade file is not found.
Use this command with caution. Make sure your instrument can support the earlier version and that
there are no compatibility issues. Check with Keithley Instruments before using this command if you
have questions.
