Thermotron 3800

[B-runner]

I am trying to build a application that I can set the Temperature on a Thermotron 3800 for a period of time.  I can't figure out how to set the temp in any of the vi's that are downloadable from Thermotron?  Has anyone done anything with these?

I've just been working on the Thermotron 7800 and had great success using simple VISA serial commands.  I don't have a manual for the 3800, but the folks at Thermotron responded quickly when I submitted a request for one on their website.  This is how I effected a Set Temperature command:

This doesn't look like you used any of the vi's that are available for download from Thermotron?  Is there a reason why?

Thermotron's Instrument Driver page says: "Thermotron recommends using the direct TCP connection approach when writing custom software applications to communicate with our chamber controllers." and "If you have considered the direct TCP approach and find that it will not meet your needs, you may download Thermotron's IVI and LabVIEW drivers" (seen here)  Even though I'm using Serial, not TCP, I figured I'd follow their recommendation.  It worked well for me.

I am trying to use GPIB to control the chamber.  I guess because it is VISA it should translate into GPIB for me.

Yes, like magic.

When trying to find the Thermotron Chamber MAX can't find it.  I believe that it is because MAX is sending the equipment the query *IDN? and the equipment wants IDEN? for a query.  Can this be changed in MAX or do I need to make a VI that will query it?

[jcarmody]

I don't know about getting MAX to automatically find it, but you can open a VISA Test Panel for your Serial port and query it manually.  Writing a VI is easier (I rarely use MAX).

Hi everybody,

Do you have the 3800 thermotron programmer controller, or do you know where can I get it? I need it but I cant find it 😕

Hi LuchoVan,

You may want to contact Thermotron directly (here's their contact link http://www.thermotron.com/contact-us). They will be better equipped to assist you with finding the 3800 programmer controller.
