Hello everyone,

I recently got the Eurolite USB-DMX512-Pro interface and was able to use it in FreeStyler (Windows) successfully.

Seeing the great potential, I am trying to connect the adapter to ola, but I am struggling to do so at the moment even though it is suggested the device is supported by the framework (https://www.openlighting.org/ola/getting-started/device-specific-configuration/#Eurolite_USB_DMX512_PRO)

I installed ola from git as described here: https://www.openlighting.org/ola/linuxinstall/#Git

I was also able to start it and access via the localhost web admin. However when trying to define my first universe, the list of available ports remains empty.
Setting the stated udev rule and also adding my user to plugdev and dialout group did not help. (was suggested here: http://opendmx.net/index.php/The_Newbie_Guide_for_OLA_on_Ubuntu)

I honestly also lack some basic understanding of the plugins, too:

Does the visibility of the device depend on the plugin activated?
What plugins do I need to access my adapter?
I already tried all the different USB-plugins without any success.

Trying to avoid the web app did not work either. When trying to set up a universe via terminal as described here: https://www.openlighting.org/ola/getting-started/using-ola/

the command "ola_dev_info" returns:

common/network/TCPSocket.cpp:158: connect(127.0.0.1:9010): Connection refused

I find it hard to find the right approach on the website, can anyone help me please?

Thanks in advance and best regards,

Felix

Hi Felix,

There's another example udev rule here for this device (embarrassingly I didn't realise until recently that the other page existed; we need to work on improving our wiki/website links):

https://wiki.openlighting.org/index.php/OLA_Device_Specific_Configuration#Eurolite_USB_DMX512_PRO

The device is available via the usbdmx plugin:

http://docs.openlighting.org/ola/conf/ola-usbdmx.conf.html

You don't say explicitly, but I'm guessing you're on Ubuntu or Debian, if you're on a fairly recent one (18.04 onwards) I'd generally recommend just installing via apt ("sudo apt-get install ola") as it's a lot simpler, although you probably want to remove your local install first.

Does the visibility of the device depend on the plugin activated?

Yes, the plugin that controls that device needs enabling, and then (in the case of most USB ones) the device will be detected on the machine and listed as an available port.

What plugins do I need to access my adapter?

The usbdmx plugin.

I already tried all the different USB-plugins without any success.

That suggests another issue then.

Trying to avoid the web app did not work either. When trying to set up a universe via terminal as described here: https://www.openlighting.org/ola/getting-started/using-ola/

the command "ola_dev_info" returns:

common/network/TCPSocket.cpp:158: connect(127.0.0.1:9010): Connection refused

That's odd, that error suggests olad isn't running, had you started the olad daemon?

So the next steps in terms of troubleshooting will be lsusb output please and also olad -l 4 output:

Hi Peter,

Thanks for the quick response.

I work with Ubuntu 16.04.

There's another example udev rule here for this device https://wiki.openlighting.org/index.php/OLA_Device_Specific_Configuration#Eurolite_USB_DMX512_PRO

I am already using this one.

The device is available via the usbdmx plugin:
http://docs.openlighting.org/ola/conf/ola-usbdmx.conf.html

I was just trying to disable all plugins except the usbdmx one, but it is still not working.

You don't say explicitly, but I'm guessing you're on Ubuntu or Debian

Yes, I work on Ubuntu 16.04

the command "ola_dev_info" returns:
common/network/TCPSocket.cpp:158: connect(127.0.0.1:9010): Connection refused

That's odd, that error suggests olad isn't running, had you started the olad daemon?

My bad, the error only occurs when olad isn't running. When olad is running the terminal where i ran the "ola_dev_info" command in does not return anything, instead the olad terminal returns:

common/io/EPoller.cpp:82: EPOLL_CTL_ADD 31, events 2001, descriptor: 0x113f540

common/io/EPoller.cpp:116: EPOLL_CTL_DEL 31

So the next steps in terms of troubleshooting will be lsusb output please and also olad -l 4 output:
https://www.openlighting.org/ola/get-help/ola-faq/#How_do_I_get_olad_-l_4_logs

Below is the lsusb output:

This is the one which disappears when i unplug the usb-adapter:

Hi Felix,

This might sound a bit odd but are you sure that's the device you have? The ones we have seen before are vendor 0x04d8 and product 0xfa63, but what you've got is
0x0403 and 0x6001 which is a standard FTDI device.

Can we see "lsusb -v" for that device please?

This sounds like it may be relevant, I'd give the steps in that a go and post your latest olad -l 4 (with the USB Serial plugin instead):

Thanks Felix, your link jogged my memory a bit more. See here:

https://github.com/OpenLightingProject/ola/pull/1292

How's your C++, fancy cloning that and fixing the remaining comments so we can merge it into mainline?

Hi Peter,

My C++ is not great but not bad either.
The pull still did nothing for me though, so I do not really know where to start.

I pulled and ran the make commands again. Is there something else to do in order to apply the changes to the plugin?

That's potentially promising, but doesn't really prove anything until you sort the permissions issue.

What does ls -al of /dev/ show for your device, or try replugging/rebooting after you added the udev rule? Are you running olad as the same user you added the udev rule to give permissions to?

I solved the permission issue!!!

Setting the udev rule right did the trick (see below).

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0666"

In case I understood correctly, this basically allows each and everyone to access all usb_devices.

I might fix the security risk opened by this in the future though...

Some other rule (deleted now) was lying around in the same folder which seemed to have overwritten the rule above in some way.

Now the device gets listed as an output port and can be added to my very first ola universe :)

Fiddling with the sliders of the dmx console makes the status LED on the addapter turn green which indicates successfully incoming signals.

Hint for other newbs like me getting desperate in the wiki:

olad cannot be run as root, so the permissions of every new usb device, which is automatically only allowed to be accessed by root at first, need to be adapted.

Thanks so much for your time, patience and new ideas!!!

Would'nt have worked without you.

I will try to connect my actual light soon. Wish me luck :)

Glad you worked around it Felix. As you say, there's probably a more subtle option somewhere in between, or it ought to be possible to make our one listed on the wiki work (indeed it's probably as simple as changing the vendor and product ID's to match, although thinking about it, there's probably another parallel rule for AMA type interfaces or something that you can probably leverage, rather than needing to rewrite):

https://wiki.openlighting.org/index.php/OLA_Device_Specific_Configuration#Eurolite_USB_DMX512_PRO

That sounds rather promising, as you say, a light will be the proof, and the smoothness of fades is generally the acid test.

Assuming that all works, I'd really appreciate it if you wouldn't mind adding the default disable option to the Mk2, then we can merge the pull request and support for it will "just work" in future versions of OLA. If you look at the DMXCProjectsNodleU1 within the same plugin that shows some code for accessing our preferences from within a Factory, which is where the change needs to be made, I'm happy to help where I can. For why I haven't just done it myself see here:

https://www.openlighting.org/ola/get-help/ola-faq/#Can_you_add_support_for_the_ltinsert-name-heregt_device

And for the bitter proof, this Pull Request, which is still awaiting someone with a different device assisting troubleshooting:

Hi,

I tried for several hours to get the eurolite usb dmx512 pro mk2 working with no success. I tried the method described in the manual as a FTDI device, with udev rules etc, The device was ready to get plugged in into a universe in OLA, but desg showed me that the device was disconnected.

Second try was to install it as usbdmx plugin, as described in the openlighting docs (http://docs.openlighting.org/ola/conf/ola-usbdmx.conf.html). It didn't show up as a device in OLA.

Could somebody please summarize the correct method to get the eurolite usb dmx mk2 to work with OLA? Obviously I missed something essential...

(one thing that adds the confusion is when I search, I get results dated from 2011 to 2018, I'm not sure which one is still valid and which not)

Thanks, gunther (user of OLA since 5 years with enttec, dmxking and artnet)

Hi Gunther,

You'll need to add (or edit if already present) this line in your ola-usbdmx.conf:

enable_eurolite_mk2 = true

To get this to work you need OLA 0.11.0 which hasn't yet been released, so you'll need to build OLA from our master branch. You don't specify your OS, but you can install most of the dependencies using the package managers, so you just need to compile OLA itself.

If it's still not working, please can we have -l 4 logs:

Hi Peter,

thanks for your reply. I'm on the way to build OLA 0.11.0 on my fresh installed Raspberry Pi-4.

At the moment I hang at the configure error: cannot find the protoc header files

checking protoc version... 3.6.1
checking google/protobuf/compiler/command_line_interface.h usability... no
checking google/protobuf/compiler/command_line_interface.h presence... no
checking for google/protobuf/compiler/command_line_interface.h... no
configure: error: Cannot find the protoc header files

I found an issue (#1463) on Github/openlightingproject/ola, which seems to cover the same error, but I don't understand what I could possibly do???

If you're building master, then the issue you linked to is long gone.

Can you share your config.log?

Are you sure you've got libprotoc-dev installed?

Hello Peter,

libprotoc-dev was missing.

I used git clone https://github.com/OpenLightingProject/ola to get the project from Git. I suppose this should be the master branch.

I got compiled and installed OLA now. In the web page (127.0.0.1:9090) I get version number 0.10.7 ???

Other questions arise: I don't have ./ola/ola-osc.conf, ola-usbdmx.conf

Anyway, here is my log file...

That would indeed be!

Yeah we don't number the master branch so you just get the latest released version number.

Other questions arise: I don't have ./ola/ola-osc.conf, ola-usbdmx.conf

Can we see your config.log, it sounds like you didn't have dependencies for those plugins installed when building it. Try installing these packages too and recompiling "libftdi-dev libftdi1 libusb-1.0-0-dev liblo-dev libavahi-client-dev".

Anyway, here is my log file...

Can you just check you don't have another olad on your machine, what does "which olad" show? And "sudo updatedb && locate olad"? Did you do a make install?

Hi Peter,

thank you for taking me by the hand and guiding me through the make process! I finally got it working. Maybe it's helpful to others, if I sum up the steps I took?

So here are my notes during installation of OLA 0.11:

sudo apt-get install git

git clone https://github.com/OpenLightingProject/ola.git ola

cd ola

(Error: could not resolve host..., therfore:)

git config --global --unset http.proxy

sudo apt-get install autoconf libtool bison flex uuid-dev libcppunit-dev

sudo apt-get install libmicrohttpd-dev protobuf-compiler libprotobuf-dev python-protobuf

sudo apt-get install libftdi-dev liblo-dev libavahi-client-dev libprotoc-dev

sudo apt-get install libusb-1.0.0-dev libcurses5-dev pkg-config liblo

autoreconf -i

./configure (optionally: --enable-rdm-tests --enable-python-libs)

make
make check
sudo make install

sudo ldconfig

At this point OLA is ready to use. Next steps:

sudo nano /etc/rc.local:

insert before " exit 0 "-line:

su pi -c "olad -f"

sudo nano /etc/modprobe.d/eurolite-dmx.conf:

blacklist cdc_acm

check Vendor -ID and Product-ID, when Eurolite usb-dmx mk2 is plugged:

lsusb

sudo nano /etc/udev/rules.d/02-eurolite-dmx.rules:

(this is one line:)

SUBSYSTEM=="usb|usb_device", ACTION=="add", ATTRS{idVendor}=="0403",

ATTRS{idProduct}=="6001", GROUP="plugdev" MODE="660"

deactivate:

open with editor and change enabled = true to enabled = false

/home/pi/.ola/ola-opendmx.conf

/home/pi/.ola/ola-usbserial.conf

/home/pi/.ola/ola-stageprofi.conf

add this line in ola-usbdmx.conf:

enable_eurolite_mk2 = true

After restarting, EurolitePro USB Device shows up on OLA Admin page (127.0.0.1:9090) and can be patched.

I hope, I didn't forget something in the summary.

Thank you once again for your help, I couldn't succeed without your guidance!

Hi everybody,

I discovered this post for setting up an Eurolite USB DMX512 Mk2 with OLA.

Since this recipe seemed to work for everybody, I tried to follow it on my RPi with Rasbian 10. I successfully installed OLA but I am having trouble when trying to access the web app on 192.168.1.11:9090 I am getting a 404 (NOT FOUND). Maybe somebody know what is wrong when looking at my logs:

Hi James,

Did you follow Gunther's steps:

https://groups.google.com/g/open-lighting/c/rDIbzhqnWxQ/m/QTFLq7N-BAAJ

Your early line still says 0.10.7, it needs to say 0.10.8 or later to have that device support (but built from our master branch).

Try running this:

sudo apt-get purge ola libola

Then:

dpkg -l | grep -i ola

And share the output of the second command.

Then follow Gunther's steps again.

Hi James,

Please reply all rather than replying privately so others can benefit too.

From the output you can see that libola1 versions 0.10.7 is still installed.

Sorry it looks like you need to run:

sudo apt-get purge ola libola1

Please do that and then recompile OLA and you should be all good!

Hi Peter,

Yes, I followed Gunther's steps but it did not work. My only assumption would be that the Eurolite USB DMX512 Pro does not get enough power from the RPi4 Usb output to communicate properly. Here is the output of the second command you named:

ii fonts-inconsolata 001.010-5 all monospace font for pretty code listings and for the terminal
ii libccolamd2:armhf 1:5.4.0+dfsg-1 armhf constrained column approximate library for sparse matrices
ii libcolamd2:armhf 1:5.4.0+dfsg-1 armhf column approximate minimum degree ordering library for sparse matrices
ii libola1:armhf 0.10.7.nojsmin-1+b1 armhf Open Lighting Architecture - shared libraries
ii libtwolame0:armhf 0.3.13-4 armhf MPEG Audio Layer 2 encoding library
rc ola 0.10.7.nojsmin-1+b1 armhf Open Lighting Architecture

Hi Peter,

Thank you for the help. Unfortunately when I uninstall ola and libola and then reinstall from source, one test is not passed when running "make check":

FAIL: ola/OlaClientTester

I installed all dependencies, except for liblo and libcurses5-dev. For these, no distributions were found (Raspbian 10). I gues this should then be the problem, or what do you think? Kind regards

James

Hi,

Nevermind, it seems to work :) Thank you so much! Although, when I type in „olad status“, it says:

common/network/TCPSocket.cpp:235: bind to 127.0.0.1:9010 failed, Address is already in use

common/rpc/RpcServer.cpp:102: Could not listen to the RPC port 9010, you probably have another instance running.

olad/OlaServer.cpp:252: Failed to init RPC server

But if this is expected, everything works fine now. Have a good weekend.

Regards

James

Hi James,

i get the same message when I type 'olad status'. Since it works on my PI without any problems for months, I think you can safely ignore this message.

Regards,

Gunther

I thought it worked for me but now the USBDMX plugin isn't even existing. What happened?

So the ola/OlaClientTester test will have been failing because OLA was still running.

You'd probably want liblo-dev (for OSC) and libncurses6-dev now (for some of the CLI example tools).

Glad you fixed it anyway.

For both of you, olad is the OLA server, so typing olad foo means run olad with the argument foo, you need to use the control system that's running olad to find out if it's running.

E.g. "sudo service olad status" or "sudo /etc/init.d/olad status" will probably do what you actually want.

Hi Cyrill,

Did it work for you before, but doesn't now? Perhaps you've got two copies of OLA and running different ones at different times? I assume this is another Eurolite Pro again?
