serial control with projector (optoma)
Posted: Saturday 14 October 2017 23:03
hi, all
i want to conect domoticz with my optoma HD25e with serial conection (should be similar for other projectors with com too), to switch on switch off, but still cant figure out how to do it right (i miss propablly something stupid
).
here is manual with described pins and commands (https://www.optomausa.com/uploads/manua ... -en-US.pdf)
- Figured out pins on serial for TX, RX with tester (2,3 on serial port)
- used FTDI conector conected to USB port (attached rx and tx and gnd to pins from cutted serial cable)
Configured screen to right setting, (baud rate 9600, bits 8 parity none stop bits 1). But when i send command to switch on or off command serial answer only some garbage characters message (but it answer when i send some command)
Any idea what could be wrong ? Could it be because wrong woltage between USB and serial port ?
thanks for any ideas
