Hi all

Just wondering if any of my Australian counterparts have ever managed to get RS232 control working on Australian shipped LCDs? Ive got a Samsung UA55ES8000 which has no ex-link port on it, only a service port. Have measured voltage and get back around 3v (TTL) which leads me to believe its not an rs232 port. Have tried getting comms through my crestron system and im 100% im doing eveything right in terms of code/serial settings/pinouts etc. Just no comms.

Is it possible that samasung australia dont utilise this port? It does have the options for RS232(UART) in the service menu. Just no talky! Have a mate who is a samsung service tech and even he cant get an answer for me!!! His boss actually had to ask him what RS232 was. lol
