Hello, thanks for your reply. Yes, sure.

JVC projectors can be controlled by lan, with TCP/IP protocol, but ask for a specific 3-way handshaking. In particular, the sequence as for JVC instructions must be:

Contoller -> connection request
JVC -> PJ_OK
Controller -> PJREQ
JVC -> PJACK
Controller -> Command you need to be executed

Here more detail (see from page 22) : [Link: support.jvc.com]

They call this as "3-way handshake" but it seems they require also the data sent as Syn and as Ack is customized (PJREQ). I tried to use normal TCP socket to send JVC command i need to execute, but projector is not executing them.

I'm not able to receive the PJ_OK from JVC after trying a TCP socket, it reports always "socket error". JVC is working correctly, because if try connection by Telnet, i obtain the PJ_OK answer.

Is there any way to enter in this 3-way handshaking somehow?

Thanks!
