Computer communication with a temperature controller
If you are using a cryostat, a displex, or some other device that uses a temperature controller that can be interfaced to the instrument computer, you should first ensure that the serial line is connected. You should then specify the type of controller in order to establish the communication. To do so, click the Settings menu ans select temperature:
The Temperature Control window has two sections. The lower section (including and below the word "Configuration") is used to define the type of controller. The upper section (above "Configuration") defines the set point.
To define the controller (in doubt ask your local contact), click on the button opposite "Select Controller:" and pick from the list. Select "lk340" if the controller is a Lakeshore model 331 or 340. Be sure to click the "Accept" button to commit your choice. You should see a confirmation message in the top section of the main dcsgui window.
If you have changed the set point you should also look at the temperature controller set point display to satisfy yourself that you have established communication. As further confirmation go to the main dcsgui window, clik "Status" and select "Temperature".
To close the dcsgui temperature window click the "Dismiss" button.
Normally the sample and control sensors are channels A and B respectively.
