Was wondering if you could give us a quick answer on sending a HEX code with the serial.

Trying to turn on a Optima projector via serial and have not found a solution to send the on or off command successfully. We have all the ports set up and can control the projector with a different piece of software but not MAX. the on code we need to send is

And for off we just change the 31 to a 30…

That should be possible "by patching" , but you may also try to handle serial port from within [jweb] object, which is based on the Chromium browser (works with serial if I'm not wrong...).

To turn it on, you need to send the byte sequence "126 48 48 48 48 32 49 13" to turn it off, it's "126 48 48 48 48 32 48 13"

YES!!! Thank you sir... how did you get those number?

The decimal value of 0x7E is 126 .. etc etc.

You can do it in a patch, number boxes support hex (and binary and MIDI among others). Change the type in the inspector. See below for an example.
