Benq MX850UST Control

CedricCedric Junior MemberPosts: 32
Hi,

I'm trying to control from RS232 a Benq MX850UST
On the RS232 control documentation from Benq
- Baud Rate Default in 115200 bps
- Data Length 8 bit
- Parity Check None
- Stop Bit 1 bit
- Flow Control None
Power ON ASCII command : *pow=on#

the code is :
dvProj_RS232 = 5001:1:0
DATA_EVENT[dvProj_RS232]
{
online:
{
send_command data.device,'SET BAUD 115200,N,8,1 485 DISABLE'
}
}

SEND_STRING dvProj_RS232,"*pow=on#"


I had try the different hexa command on the forum, but doesn't seem to work.

If anyone have any suggestion or any other protocol, thanks.

    In Netlinx you use single quotes for ASCII strings

    SEND_STRING dvProj_RS232,"*pow=on#"
    Should be
    SEND_STRING dvProj_RS232,'*pow=on#'

    Hi,

    Thanks, had try both in fact (with single and double quote)
    I just receive a file from benq with all the rs232 general protocol, if someone need this file, just contact me.
    Also on this file for the power on the ASCII command is :
    <CR>*pow=on#<CR> so
    SEND_STRING dvProj_RS232,'<CR>*pow=on#<CR>'
    and on Hexa:
    SEND_STRING dvProj_RS232,"$0D,$2A,$70,$6F,$77,$3D,$6F,$6E,$23,$0D"
    Steel not working

    I will try to make an other rs232 cable, just to be sure, had take one already made.

    Ummm.. The <CR> is a $0D hex.

    So, you have to make a hybrid string

    SEND_STRING dvProj_RS232,"$0d,'*pow=on#',$0d"

    They really should have covered this in Programmer 1 class.

    Yes, we had covered this in programmer1
    the problem was coming from the wire
    The one I was using for the test was working on other device but not the benq

    Had to make a ''special one'' for this connection
    Master -- Benq
    1--1
    2--3
    3--2
    4--4
    5--5
    6--6
    7--7
    8--8
    9--9

    on the other cable only RX TX and GnD are connect
    Now it's working can turn on/off from ASCII or hex

    Thanks for your help
