Re: TV One 1T-SX-644 HDMI Switcher


 

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.

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.

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!
