[opendmxusb] Open DMX auto detection

[Gary H. <car...@ho...>]

Hello.  First post here.  I am adding support for Open DMX to my
application.  There are several code samples for interfacing with it so that
is no problem.  But all that I have seen simply assume that if the FTDI Open
command succeeds that it is communicating with an Open DMX device.  In my
case, my application may be connected to multiple devices that use FTDI
chips for USB.  So, does anyone know how I would be able to determine when I
am actually communicating with an Open DMX and not something else?  I looked
up the default FTDI VID/PID and they are 0x0403 and 0x6001.   Are these what
Open DMX uses?  

 

Thanks,

Gary

Re: [opendmxusb] DMX USB Pro under Linux

[Zac S. <zs...@gm...>]

Hi Ronen,

I have had a look through the code on those pages in particular the Linux
sample code and couldn't find anything that looked like it was for
outputting to the USB DMX Pro.

Could you possibly point me in the right direction?

Hi All,


I am interested in using a DMX USB Pro for a project I am working on that will be running on Linux.

 I have tried compiling dmx4linux 2.6.1 under Ubuntu 8.10 with Kernel 2.6.27-9, so far I have not had any success in compiling it, it also looks like the project hasn't been updated in a while.

Are there any open source projects that you could recommend for working with the DMX USB Pro under Linux?

Hi there!  

            After two years of having no problems at all with the PRO, I
went to use 4 mac 250+ units on the weekend, and strange things were
happening…

 

First the macs indicated DMX was present, but did not “home” the stayed a
0,0 and did not respond,  looking in the mac’s menus, it was receiving a
start code of 200 ?!?!? 

WTF, thinking my box was stuffed, I went home and got another PRO,  same
story!

 

Im not an idiot, the macs were set up and addressed correctly in dmx mode
and on personality 4, as was my software correctly set up…

 

I have done this before successfully before on many occasions, just not with
these macs but entours and other macs..

 

I discovered that, even though the macs were already on “dmx 4”, if I went
into pers/dmx4 and press enter they started to work!

This was the same for all four macs…

 

So they were already on dmx4 from powerup, but to make them respond, I still
had to go into the menu, and hit enter on dmx4 even though it was already
there!!!

 

Any ideas, because if I lost power, I would have to scale the trusses during
show to tell the macs to do what they are already set for!?!?!?!?

 

I wasted and hour and a drive to figure this out, it’s really bizarre..

[opendmxusb] New DMX USB Pro software for Mac and Windows

[Glenn M. <gl...@ch...>]

I just released new beta test software for both Mac and Windows that uses
the Enttec DMX USB Pro interface box.

miniStageConsole is an extremely simple, 24 channel, unlimited cue, light
board with MIDI input so you can control it with a MIDI control surface such
as a Behringer BCF2000. It is currently running lights for a show controlled
by QLab showcontrol software.

This software is designed for small theaters using conventional dimmers and
fixtures. No moving light features or fancy DJ/nightclub features.

Hi! Recently I purchased a USB dmx pro as well as a 4 channel dimmer
pack. Everything works great i've been able to use various control
software to get everything working in a standard way and so far I'm
pretty happy with everything. However, my intent when buying the DMX
usb pro was to use it to integrate lighting VIA c++ into a specific
application that would then control the lights based on
whatever/whenever I sent instructions through the USB pro through code
I hope to integrate into the application. I do know BASIC C++, but
i've been searching around and looking at some of the DMX pro source
offered on the official site, and I havn't been able to get anywhere.

Would anyone be willing to work with me to just get the basics
running? For now all I want to do is to set the intensity of the
individual channels on my dimmer pack in a standard C++ program - no
fancy gui's no fancy slider bars, just a simple instruction "Set
channel 3 to 30%" or something of that nature. From there I hope to
understand the code enough to experiment and do various effects with
it - and hopefully learn enough to work with RGB Led lights when I do
manage to purchase some.

Thanks in advance for any help anyone can give me - just shoot me an
email back if you'd be willing to help.

[opendmxusb] Vocus 2 Beta testers? Also new app...

[Rowan M. <row...@in...>]

Hi All,

            Im looking for volunteer’s to beta test Vocus 2. :-)  

 

Vocus 2 has had a complete disconnection from previous code and uses
advanced filtering and detection methods to improve accuracy and ‘real
world’ sensibility.

It also includes some extra functionality with the implementation of a
fixture control module and pre-heating capabilities.

 

http://users.on.net/ Vocus2.0-0208-upgrade.rar   

 

This requires you have SAPI installed on your machine, in case you don’t,
obtain and install the “full installer” of Vocus 1 before running Vocus 2. 

 

For DMX transmission to occur, you need a key, and an Enttec DMX USB PRO or
ESP-NET supporting device.

 

 

I am offering 5 keys to the first English-speaking people to send me a
sample (in 128kbs MP3 please) of their voice saying in their natural voice… 

“Channel One Hundred At Forty Three Percent“ followed by a silence of 2
seconds in length, then “ AND    GO NEXT     GO BACK     MASTER”  and then
some random whatever sentences for about 20 seconds.

AND a detailed account of their experiences or suggestions you might have
with Vocus2.

 

If It’s all too hard….  And by the way, your voice won’t be used for
terrorist purposes. :-)

 

Interested parties please contact rowanmac  _@_  internode.on.net 

 

Cheers,

   Hippy

Thanks heaps guys, so the haze switch off and short 2+3....=20

  Hippy.

[opendmxusb] Le Maitre Neutron Hazer

[C S T. <cst...@on...>]

Hi all
Sorry to advise that the Neutron Hazer does not have variable output =
even with the DMX interface.
Once DMX has gone above 56%, the Neutron starts it's output cycle. The =
Haze switch is a local control of the same. You have not seen an =
immediate response because there is a pause before output gets going and =
also after the 'switch' is released, haze continues.  I seem to remember =
about a 20 sec delay.=20

Also for those like myself who constructed a DMX interface for it, the =
power available on Pin 3 is very limited - it is controlled by a FET.
My solution was to increase the size of the Voltage reg to feed the =
interface, insert a fuse in the line and only use a opto isolator to =
generate the switching signal.

Even more important,  despite the LeMaitre manuals, the pin out IS :
Pin 1 GND
Pin 2 Control (ie +10)
Pin 3 12v source.

Hi guys,
   Not really dmx question, but i need a quick answer :)
some of the smartest people i know read this list,

Friend (my best man, oh yeah btw im getting married) has a la maitre =
hazer
and no dmx interface to go with... the hazer has 3-pin cannon 10v input=20
and a 'haze on/off' switch..

pin 1.. gnd
pin 2.. (10v input i think)
pin 3.. +11.8 volts

he needs a way to control haze level, i figure a pot/switch between
pins 2 and 3 should work, but he put a button on there and says
its fanning/heating but no output..

how can i get him going? he leaves on tour in two days...
should the haze switch play a part in this?

any ideas? please!?!?

Actually, that's incorrect. A well-written application
is 100% reliable on OS X, as long as you're careful
not to cut power to your USB hub. Just use a UPS like
you would on any other console. A few polite
complaints to FTDI would certainly result in a bugfix.
We use the Pro (often many of them at once) for every
one of our shows, and we've never had a show fail
because we relied on it.

Some Windows boxes reportedly also have trouble
starting the Enttec widget without help from a powered
hub.

In response to your other question, you can, in fact,
run various Windows apps under Parallels (e.g. hog 3),
assuming your peripherals support it. We've done it.

Re: [opendmxusb] Open USB DMX on Mac

[Rowan M. <row...@in...>]

The pro should be fine shouldn't it? timing not so critical and baudrate 
ignored anyway...
all thats needed is ftdi drivers?!

Re: [opendmxusb] Open USB DMX on Mac

[Zac S. <za...@el...>]

So sounds like Mac isn't the most reliable platform to use any of the Enttec
widgets with for a show. Has anyone tried running windows through Parallels,
what are the results with that?

Zac

Happily, they fixed this a long time ago -- in 10.4.0,
in fact. (See example below.)

Although we did manage to use it in several shows, we
never managed to get a full universe of output from
the Open DMX device. It would corrupt the frame
starting about halfway through, and then of course
break time was extremely jittery. We switched to the
Pro device as soon as we had our hands on one. Its
only drawback on the Mac is that it requires a powered
USB hub to start up (though not always to run after
startup). Oh, and FTDI's drivers occasionally trigger
a kernel panic when the device is unplugged (either
from USB or from its power source) while in use.
That's rare, though, and hard to reproduce
predictably. If it weren't for that quirk, we wouldn't
absolutely need to bring a UPS for our console.

Here's a snippet of dead code for driving the Open.
This is part of the stuff that never worked beyond the
first ~half of each frame on OS X. We abandoned it
because the Pro is well-behaved. You can see from it
how to set the speed in 10.4+.

It would be lovely to figure out how to drive a whole
universe from the Open with relative stability. There
are a few experimental effects that depend on
frame-by-frame synchronization. I'd love to try them.

// Open DMX output setup (half-working, abandoned).
const char *path = [_devicePath cString];
int ret = -1;
int fd = -1;

Happily, they fixed this a long time ago -- in 10.4.0,
in fact. (See example below.)

Although we did manage to use it in several shows, we
never managed to get a full universe of output from
the Open DMX device. It would corrupt the frame
starting about halfway through, and then of course
break time was extremely jittery. We switched to the
Pro device as soon as we had our hands on one. Its
only drawback on the Mac is that it requires a powered
USB hub to start up (though not always to run after
startup). Oh, and FTDI's drivers occasionally trigger
a kernel panic when the device is unplugged (either
from USB or from its power source) while in use.
That's rare, though, and hard to reproduce
predictably. If it weren't for that quirk, we wouldn't
absolutely need to bring a UPS for our console.

Here's a snippet of dead code for driving the Open.
This is part of the stuff that never worked beyond the
first ~half of each frame on OS X. We abandoned it
because the Pro is well-behaved. You can see from it
how to set the speed in 10.4+.

It would be lovely to figure out how to drive a whole
universe from the Open with relative stability. There
are a few experimental effects that depend on
frame-by-frame synchronization. I'd love to try them.

// Open DMX output setup (half-working, abandoned).
const char *path = [_devicePath cString];
int ret = -1;
int fd = -1;

// Note: O_DSYNC not recognized by compiler
if( path && (fd=open(path, O_WRONLY | O_NOCTTY))>=0 ) 
{
  _open = YES;
  struct termios oldOptions;
    
  if( ioctl(fd, TIOCEXCL) == 0 ) { 
    
    ret = tcgetattr(fd, &oldOptions);
      
    // set options
    speed_t speed = 250000;
    struct termios options = oldOptions;
    options.c_cflag = (CS8 | CSTOPB | CLOCAL | CREAD);
    options.c_lflag &= ~(ICANON | ECHO | ECHOE |
ISIG);
    options.c_oflag &= ~OPOST;
    options.c_cc[ VMIN ] = 1;
    options.c_cc[ VTIME ] = 0;

    ret = tcsetattr(fd, TCSANOW, &options);

    // starting in os x 10.4, you can actually set the
speed for real:
    ret = ioctl(fd, IOSSIOSPEED, &speed); 

    // clear tx

I believe there is all sorts of problems with the mac, like unable to =
set non-standard baud rates, as is required by dmx protocol.
Pls correct me if im wrong..
