Hello everyone,
I would like to create a system to control three identical Benq projectors with a single arduino via RS 232.
(only the turn ON/OFF command needed)
Benq gives the following command and settings :
Write Power On *pow=on#
Write Power off *pow=off#
Baud Rate:
Default in 115200 bps, but changeable in OSD menu :(2400/4800/9600/14400/19200/38400/57600/115200)
Data Length:8 bit
Parity Check:None
Stop Bit:1 bit
Flow Control:None
Is it possible to wire only the TX after a MAX 232 to the RX of the 3 projectors?
Or is it possible to build 3 full 232 links ?
Hardware wise I was thinking about these :
