firmware upgrades?


Dunno. where did you get the command list from? (Stuff like <CR>*pow=on#<CR>)

It should work. You could try using a terminal program to manually connect. 
From skimming the manual for that projector it says the RS-232 is for firmware 
upgrades only...

Hi

With the recent talk about comport I have tried to use it to control a
BenQ MX660P Projector and I am having no response from the machine.

RS-232 protocol

Baud Rate



115200 bps (default)

Changeable(2400/4800/9600/14400/19200/38400/57600/115200)

Setting in OSD menu

Data Length



8 bit

Parity Check



None

Stop Bit



1 bit

The command to turn it on is:

<CR>*pow=on#<CR>

But I am getting no response from the machine.

I am using the ascii list of bites to send the message, maybe this is
incorrect?

Perhaps someone may shed some light upon this for me?

I am on Windows7, pd 42-5 extended
