It's really easy and convenient to control your scope fan using the supplied cable and the Seletek Armadillo controller:

 With the controller unpowered, hook the cable at both the Armadillo's EXP port and your scope fan plug.


If you have never done so before, launch “Pin by Pin EXP” from your start menu:


Then go to the configuration window and, to avoid mistakes, label Pin 2 as “Scope fan”, then press OK.





Then go to the configuration window and, to avoid mistakes, label Pin 2 as “Scope fan”, then press OK.


You are done! Just selecting ON or OFF from the Pin By Pin main window you'll be able to switch the fan on and off from the comfort of your desk, maybe far away from the observatory.
