70 WARNING: the way of connection for this chassis is different compared to the other Q52x chassis!
LVDS
TRANSMITTER
This chassis uses UART communication instead of RS232. The voltage levels are different.
When you connect this chassis with the ComPair RS232 cable this might result in damage of the TV set.
Use cable 3138 188 75051.
