In API documentation setatate is listed, however I would like to run a script that cycles contact quickly on off. Has anyone had success with this?

Matthew Official comment Hello Daren. I'm very sorry you've experienced these issues with the product thus far. I will say, based on a very large number of other users who have had successful use of the product, I think this is likely a solvable problem if you would still like our help? I would be happy to help diagnose the overcurrent/power issue, and also find a solution to the momentary requirement, if you are interested. I understand your current iTach has some or all damaged relays, so if I could gather some more info about that, I can consult with the engineers. As you may know already, the solid-state relays on the IP2CC are rated at 0.5A/24V. As for the momentary switching requirement, it is very likely that we can devise a solution even with the Zoom Rooms scripting you have described. For example, if that Zoom Rooms script is sending an ASCII string "setstate,1:1,1\r" to close a relay, then it should just as easily be able to send a similar ASCII string "setstate,1:1,1\rgetversion\rsetstate,1:1,0\r" to create a close/open 'pulse'. (The "getversion\r" between "setstate" commands is an idempotent way to effect a delay. And, if you need longer delay/pulse you can simply add a few more "getversion\r" commands until your pulsewidth is adequate.)
Let me know if that helps at all, and we can also look into the overcurrent relay-fusing situation.
Thank you! -
Brian Kerth Hello Nathan,
We have seen scripts like this in the past. The device is only looking for the command itself. If you create a script that includes a brief pause, it should execute and give the momentary contact.

Noe, Daren Do you have a sample script you can share?

Noe, Daren My control Application is Zoom Rooms which used JSON scripting so there is no way to insert a pause between commands. I bought a dual external timer relay that could create the momentary closure I need. Unfortunately it worked great for 10 minutes then the relays on the Itach fused closed. I even had a reverse polarity protection diode to protect the relay, but they still fused closed. The Itach relays apparently can't handle any current at all without fusing closed. Very disappointed that Global Cache doesnt have any interest in adding a momentary closure option to their Itach IP2CC. Its a neat product that falls short of what is needed for screen controls in a classroom. Looking for a new product that will work.

Garybixler The point is not having to send two commands to accomplish a momentary relay closure. If the second command does not get through for whatever reason the relay may remain closed causing unexpected problems. I have never seen a relay unit that doesn't allow for momentary closures which usually has a configurable timer. I have moved on to a cheap two relay ethernet unit that has an adjustable jog timer. Not in a nice case like the iTech unit but works perfectly.

Noe, Daren Thanks for adding support to my request Garybixler. I did sort of the same thing. I added a seperate 2 relay unit ($20 on amazon) that has an adjustable timer. I am still using the Itach for the ethernet connection, and using the Itach to activate the timer relays. It would be so easy for Itach to add a momentary command and maybe a potentiometer to set the momentary time. But, it seems they are not interested in improving the product.
