As far as we can tell everything is as you say, we have the module in slot 4 and are attemting to get the state of the input directly from the module itself not the dashboard. We simply created an object called Dig4 and set it equal to DigitalInput(1), here's the code.

We have also used our multimeter to check the limit switch and the digital side car works for everything else we have used (motors, compressor, gyro and so on). We also found out earlier that this year it is illegal to connect the limit switch directly to the jaguar in accordance to R<54>.

Soo, we are still stuck.
