Keithley 230 driver?

[dukeA]

I hvae labview 8.5. I want to control keithley 230 prog voltage source. I found only on

the driver under InstrumentI/O but there is only one single vi to program level.

I need to do stuffs like initialize, read status, turn on off ouput and program voltage/current level.

I got one link from NI application download and try it out but it does not work. Attached is the VI.

I verified that the gbib address is correct and this unit has been working with other system.

Thanks

Hey dukeA,

The drivers you found on our website are not NI authorized or supported. They are provided by customers and people who feel like developing them, hence the existence of only one vi in the library.

If you check the 230's programming manual you'll find the needed strings to be sent to accomplish your initialize, read status, power on or off, etc...  That manual is attached and i read some of it. DCL is the generic clear command that will initialize the device.  Try passing this as the string into the GPIB Write.vi instead of the string coming out of the line select vi.  Let me know if this command and the others that are found in the manual work for you.  Once we get response from your GPIB device we can easily develop your Vi to make it an easy selection to send commands without changing the block diagram everytime.

Thanks,
