Ethernet communication using Keithley 2701 in NI MAX

[jseele69]

I'm trying to set up my Keithley 2701 in NI MAX so I can use it in LabVIEW but no matter what I do, NI MAX does not recognize it.  I have the Keithley driver installed as well as VISA.  I've also verified communication in the command prompt using ping, so I know it's communicating.  I've also used kickstart on this computer, so I don't understand why it isn't working.  Someone please help.

Hi jseele,

do you know the rules on how to define IP addresses and the usage of leading zeros for such addresses?

I guess you missed something like this!

[jseele69]

Yes, I know about leading zeros.  I've tried with and without them.  Like I said, I've set up the IP to work with kickstart just fine.  So that isn't the problem.

Just use the raw VISA Resource name. You don't need to set up anything in NI Max to use VISA Ethernet Devices in LabVIEW.

Use something like "TCPIP0::169.254.248.70::inst0::INSTR" (replace with IP Address) instead of creating a VISA Alias.

Using what Shockhouse suggested should get you mostly there, but I feel it important to mention that it's likely the reason it's failing is that you put the instrument name in the VISA string as "Keith" instead of "inst0".  99%+ of the time, that portion of the string needs to be "inst0".

Also, I note that you're using the 169.254 address range for your IP addresses.  This can work for a while, but that range is the "I looked for a DHCP server and didn't find one, so I randomly picked one" range.  If this is meant to be a permanent connection, it's probably best to set up a local 192.168 range with static IPs.

I tried that and it did not work.  I was able to get response by changing the port number in NI MAX, however.
