I have been bashing my head against the wall trying to control any of my 15 projectors via serial commands and my macbook pro. I am using a USB serial interface with CoolTerm and a cross over serial cable. I see the usb serial driver and looping back pin 2 & 3 shows the exact hex code that should work coming back from the pin. However it doesn't work to turn on the projector. Power on cmd is: 0x06 0x14 0x00 0x04 0x00 0x34 0x11 0x00 0x00 0x5D but tech support said to run it as: 06 14 00 04 00 34 11 00 00 5D Anyone doing this successfully on a Mac with any projector. View Sonic said they didn't have one to test it on!!! Help me Obewon Kanobee, you're my only hope!!!!
