I have a benq w100 projector which has performed great for me. I am looking to control it via serial communication through my PC. Just the basic stuff.

The projector has a 8 pin mini din port, so I bought an 8 pin mini din male to DB9 female for connection to my PC. Benq don't have any information on their website so I email them and they sent me the code spreadsheet (attached).

I've tried setting up bacth files to transmit the codes, but i can't even guarantee that my connection settings are correct.
Code:
MODE COM1:19200,N,8,1
ECHO ^x06^x14^x00^x03^x00^x34^x11^x00^x5C >COM1

Can anyone tell me the connection settings for the benq W100 or point me in the right direction please?

Thanks for code table :)

I tried to use different speed and when I use 115200 b/s,8,N,1 it works fine!
 
Can you tell me the pin outs on the projector
We have a Sp830 Proj with a 8Pin mini din
:lease:
 
Hi! The pinout is:
TX (DB 9 pin 2) = 8 pin mini DIN pin 7
RX (DB 9 pin 3) = 8 pin mini DIN pin 1
GND (DB 9 pin 5) = 8 pin mini DIN pin 4

Hope that helps!
For the layout of 8 pin mini DIN pins, do a google search on:

Hey!

Thanks for the code table, just what I needed. However, having a little trouble reading in information:

SENT>07 14 00 05 00 34 00 00 15 01 63 (to get lamp life)
RECV<05 14 00 06 00 00 00 DF
RECV<03 00 00 FC

Any idea how to convert that hex into decimal?


Cheers

Nate

Multiply the first digit by 16 then add the second digit. So Hex "34" is 3*16=48 + 4 = 52.

For letters, A=10, B=11, C=12, D=13, E=14, F=15 etc. so "DF" = 223 (13*16 + 15).
 
Thanks for the excel spreadsheet - most of it makes good sense. There were a couple of things that I had questions about. I will note here that I'm writing code for this and the unit is in another state so I don't have it in person to work with.

This document does not have a "blank off" command. There is a "blank on" so it seems odd that you can turn picture mute on but never turn it off. Does doing something else like giving it a power on or input select turn the blanking function off?

Also I noticed that it has a command to request power status and lamp hours, but does not give any detail about what comes back from the projector? Does anyone have the format of the data for the lamp poll and power status?
 
Will these codes work with other BenQ projectors like the W5000, W10000, and W20000? BenQ can't see to find the codes for us - great projectors though... any feedback is appreciated.
