TV One 1T-SX-644 HDMI Switcher


 

Has anyone had any luck controlling this via RS232? I am almost to the point of beating my head against my laptop because I can't get it to work. Any assistance on this would be greatly appreciated. It's a very simple configuration. Multiple HDMI sources into the switcher and out to a display. C2N-FTB buttons being used to drive this switcher to select the input. Each button press hits a MOS which then drives the SIO which SHOULD trigger the switch. I have checked all my settings and rechecked the 232 cable to the switcher and it still won't work. HELP PLEASE!!!


 

I have a tvone c26104 that I am using in a current system. After about 2 mins of looking at it not working over 232, I switched to IP. I don't know if the cable was pinned wrong or what, but I have always controlled tvone's over IP before this and it is just easier for me because it works. 232 will work too, I am just to lazy to figure out why it is not working. :)

If it's like any of the other TVOne horribleness, pressing buttons on the unit itself should generate strings that appear coming in to your com port. Other dreck I've worked with from these folks (IIRC) have been 57k 8N1, just pins 2, 3 & 5.

So... After calling TV1 support, I finally found why my programming wasn't working.

Even though it is not in their documentation ANYWHERE, you are supposed to send a CR at the end of each command. The response I got, "We just assume that you know to send one at the end of the string..." NOT IF IT ISN'T IN YOUR DOCUMENTATION THAT I NEED TO DO SO!!! Vent over. Have a great weekend everyone!

This ^^^ is the super Chip tip of the day!!! I was working with a 1T-C2-750 and couldn't get the strings right. Just push the button you want to push, take the string it spits out, change the beginning F44 to a F04 and put a ?? in the checksum and you are good!


 

More devices need to support setting the checksum to "??". The TVOne
protocol is a disaster, but that is one redeeming feature -- B&K receivers
also implement an optional checksum I believe.

FYI. One thing that got me on my last tvone job is that the IP had been set to "on" and that killed the com port. I think if it set to "auto" or "off" the com port works without issue.
