Ah, my mistake- I misread the original post. Probably the reason you're seeing 28ms instead of 20ms period is because there is some overhead when switching the relay on and off. The API call has to create a packet that is sent down via USB and then a VINT packet is sent from the HUB to the relay Phi...

Have you tried controlling the on/off time with setDutyCycle and setFrequency? You should be able to get more accurate control using these library properties.

If you still have the old program, you may need to download the old version of our drivers to get it working. You can have both Phidget21 and Phidget22 installed on the same computer, so no need to uninstall.

You need to update the Phidget drivers on your SBC to a newer version, since the MOT0110 is a relatively new product.

Go to System -> Packages in the web interface, click on "Refresh Available Packages" and then click "Upgrade all Packages".

We just tested it in-house with a copy of Artisan and it recognizes it just fine.

Yes, those devices will allow you to use your thermocouple with Artisan software. However, it's worth mentioning that the HUB0007 just came out this week, so Artisan software might have some issues with it (e.g. if any part of their code assumes a hub always has six ports, which has been true up unt...

This could be caused by a mismatch in library versions- are both the computer running the code and the computer with the Phidgets connected running the same version?

The inputs on the DAQ1300 are all isolated individually through optocouplers, and they're all individually current-limited.

Phidget21 is no longer active, and it does not support the 16x Solid State Relay Phidget or any VINT devices.

It may fix it. There are a lot of things that can cause webcam issues (out of date drivers for example) but the first thing to check on the SBC4 is which port you're using.
