Our Grass Valley Ignite suddenly and without warning quit working with the Chyron Hyper-X. It turned out to be the Telnet was disabled on the Hyper-X. There is a way to see if this is correct. Look down int he bottom right corner of Lyris and on the staus bar it should say "II T" and if you do not see that then it is not enabled.
To fix this go to the Lyric program and go to Config > Intelligent Interface.
After about 5 seconds the status in Ignite changed to green and everything was working properly.
