BARCO projector Widget Control

Postby Sam Kriemelmeyer » Sat Sep 20, 2014 5:12 am

Here is the key to working with most Barco projectors and the new Widget Designer Projector Node. Barco is one of the harder projectors to remote because of the hex code needed to operate from Widget.

This new node makes a direct connection to each projector so the WD connection manager is not needed. In our case the Barco projector is set to 2.0.0.201 on port 43680.


Here is a screen shot of the new projector node in WD v821 RC

Each of the boxes has a small number to the right of it. Below is the number of the box and the command to be entered in the field.


box then command
5 [hfe h00 h00 h03 h02 h76 h1a h01 h96 hff]
6 [hfe h00 h00 h03 h02 h76 h1a h00 h95 hff]
7 [hfe h00 h22 h42 h00 h64 hff]
8 [hfe h00 h23 h42 h00 h65 hff]

13 [hfe h00 h76 h9a h10 hff]
15 [hfe h00 h76 h9a h01 h11 hff]
16 [hfe h00 h76 h9a h00 h10 hff]
17 [hfe h00 h2 h42 h63 hff]
19 [hfe h00 h21 h42 h01 h64 hff]
20 [hfe h00 h21 h42 h00 h63 hff]


Enjoy!

I'm new to the subject of projector control. Does the WD-node work for other projectors as well? I will have a Panasonci PT-DZ12000 projector in an unpcoming show and I would like to control the shutter through Widget Designer. The manual says about the PJLink protocol that "30" is "shutter mode off" and "31" is "shutter mode on". Or is there another solution? Thanks for helping.

Hi David
yes the node works for every projector that supports TCP communication

I worked with this projector lately. The easiest way I found is to transmit PJ Link commands. In that case its more comfortable to turn the password off first. You do that in the browser. In more detail:

using the remote, under Network > Network Control > "Web Control" Enable (and of course "PJ Link" Enable)
using a browser, connect to the IP address e.g. http://2.6.0.1

enter default login
Name: admin1
PW: panasonic

in web control > "change pw" > for Administrator (not User!)
in section "current" eingeben:
Name: admin1
PW: panasonic

in section "new"
Name: admin1
PW:
Retype PW:
only the user but leave the pw and retype pw field empty!!

OK -> Browser aks you for new pw that means that the old default pw has been changed successfully, close

if wanted, disable "web control" again

30 and 31 sound weird to me, I remember that PJ Link commands always start with a "%", I just looked it up what the coolux manual says, and for power off it is "%1POWR 1[CR]"
I think the shutter was
AVMT 30 = Shutter close
AVMT 31 = Shutter open

Hope that helps :)

How hard would it be to expand the projector control to poll for other readings and display the return if it was just a numerical value?
I'm thinking lamp hours, temperature, etc.

We could use algorithms to display warnings and so forth then...

Hi,
the upcoming Widget release, there is already a new function. You can send any command to the projector ("ASCII Request") and display the response in another control like a Label.

Despite of that, it is of course always a possibility to create a TCP connection in the Connection Manager, send commands like TCPSend,ID,message and retrieve the answer with a TCP Input node. This is the old workflow before the projector node was created. In fact, this is what I would still recommend when you deal with many projectors as the node sends the request in a dedicated interval. The command on the other hand, is only send when you execute it. So, for asking whether the projector is still functioning I would send requests with the node, every 5seconds lets say. But to ask for lamp hours I would only send the command once a day automatically, maybe on startup, and manually if somebody presses a button.

Afternoon All

Does anyone have the command structures for Barco HDQ-2K40's at all?

Currently looking for the control commands for power/shutter/test pattern and input if would be so kind as to provide them?

Many thanks

Matt
