Controling a Samsung 460MX-2 with RS232
Hello! Im trying to get a Brightsign HD1010 to change the input on a Samsung-screen over RS232 with a GPIO-action. I have tried a couple of different ways of writing the string, but i can't get it to work. According to the samsung manual the command should be in hex and what I can find is that power on (just for easy-testing) should be: 0xAA 0x11 0xFF 1 1 12 AA is the header, 11 the command, FF is ID, 1 is datalenght, 1 is "power on" and 12 is the sum of every number exept the header. (accualy 112, but for 3 digit sums, remove the first digit) How im I supposed to write the command in BrightAuthor? Thanx! //Dan
