Can anyone tell me how I can read .mxd files and extract the relevant discrete codes. I am trying to get the discrete on and off codes for my Hitatchi projector. I'm pretty sure they will be the same as the PJ-TX100's. Someone has posted a .mxd file with the discretes inside but I am not sure how to read or extract them...

the file is here:

Can someone help me out....?

Thanks

Paul.

I don't know any generally available way to extract codes from an .mxd file. I have a couple ways I can extract individual codes from an .mxd file, but those depend on special hardware (the easy way I just did it) or lots of effort plus special knowledge.

I looked at the signals in that .mxd file. The protocol is NEC1, the device is 135.69

As described in other threads, you can use MakeHex to generate the full set of 256 signals.

The On command is function 29 and the off command is function 30.

In condensed Pronto Hex, those are:

900A 006D 0000 0001 8745 1DE2

900A 006D 0000 0001 8745 1EE1

Do you have any learned signals for your projector? Rather than guess a model to get discretes from by similar model number, you should look at models that have the same ordinary signals as your model.

Those look correct - the model is dec 135.69 which equates to 8745 I think.

Those codes work perfectly.

Thanks - I think the Hitachi PJ-TX300 is just a revamped PJ-TX200 which is based on the PJ-TX100 .. so the remotes are pretty much the same.

Thanks again for you help.

Paul.
