Martin,

I meant RJ45, through a local area network :)

I sent the [devices( message but nothing came back. I guess the projector has to be connected to the router not directly to the computer. Unfortunately, on the list of devices on the router's interface the projector does not appear.

Will try your advice, especially useful the non-hexa code. Thanks

Popesz

Dear List,

did anyone on this list try to control a projector via LAN?
I guess comport works only for COM1 controller.
It should work with any serial device your OS knows about. You can specify it by name or use the [devices{ message to get a list of what's available on your machine. (And dont't forget to set the correct baud rate)

I plan to use RJ-45, but not sure if the comport external can handle it.
Do you mean RS485 hardware or RJ45 connector? RS485 should work the same as an ordinary serial port, except for the bus direction signal, which has to come from somewhere.

E.g. a message [02h 00h 00h 00h 00h 02h( could turn on a projector, in my case it is NEC.
You would just send [2 0 0 0 0 2{ in that case, since Pd doesn't interpret hexadecimal notation.

Any hints are welcome.

Best,

Popesz
