    Hi all,
    I have happened upon a surplus video projector (NEC M260W) and am going to use it for a virtual Santa display between light sequences. Have it networked and have tested control with the PJLink test software successfully. I seem to be struggling to get xSchedule to talk to the projector though. IP address is correct, as is the password, but no reaction from the projector... I would appreciate anyone pointing out where I may have skipped a step ??

    I know nothing about it specifically, but is it the right protocol (tcp / udp) and port number?

    Thanks David, port number was my first thought but other than IP and password I couldn't locate anywhere to configure them.

    I did see a reference in the NEC docs: The TCP port number used is "7142".

    I've never used the projector plugin so can't help much there.

    Thanks again - the port for this model is 4352. PJLink test tool operates it fine, just can't figure out if and where any advanced config in xSchedule is...

    Pjlink has been implemented as best I could to the spec but I can't test because I don't have a projector. If you could do a packet capture of the exchange between your software and projector vs the scheduler and the projector I would be happy to investigate and fix.

    Sorry Keith, did the bolt on reply and missed your offer ;-(

    Here is the logs from thew PJLink text software with a power on, video mute on, video mute off:-
    [2017.10.31 07:37:55.777] Connect TCP

    [2017.10.31 07:39:49.454] Close TCP socket(every time).

    The xSchedule logs show:-
    2017-10-30 10:54:12,507 7280 log_base [INFO] PJLink logging into 10.7.10.11.
    2017-10-30 10:54:12,507 7280 log_base [ERROR] PJLink refused connection.
    So are not even getting to send the commands. I removed the password in case that was why the connection was refused but same error.

    It does and it doesn't. Can you put the traces in a Dropbox and send them to me.
