Written by Thomas Hinterberger.
This HOWTO outlines a method for creating an ArtNetNode on an Intel/AMD32 Computer (minmum proved: PI/200 32 MB Ram/400MB Harddisk ) using an Enttec Open DMX USB Interface (not the Pro). For instructions on how to install on to a USB stick see http://d-i.pascal.at/
This howto uses the Debian Sarge Netinstall-CD-Image (100 Mb) - http://www.debian.org/releases/sarge/debian-installer/
The computer must be connected to the Internet to download the packages. Its easiest iy you have a DHCP server on your network (most routers come with this feature)
Contents
Initial Install
For installation follow: http://www.howtoforge.com/perfect_setup_debian_sarge (enter linux26 at the boot prompt to install a 2.6 kernel)
choose Node1 as hostname and ArtNet as Domainname
on page 2 of the installation guide "debian software configuration" you choose manual package selection by going there with the courser and use the space tab to select it.
On the Configuration Exim v4 you choose no configuration on this time and you will end up with aptitude
close aptitude with :q
log in with your username and password
now you typ to the console with the following convention:
- command Type command as root- to get root type 'su' followed by the root password
$ command Type command as user - to get user type exit
$:su #:nano /etc/apt/sources.list
You add the following line:
deb http://www.nomis52.net/data/debian ./
ctrl (strg) o + enter to save ctrl x to exit nano
#:apt-get update #:apt-get install kernel-headers-$(uname -r) g++ make libartnet1 artnet-examples
before you say yes note the version of your kernel-headers
#:exit $:wget http://www.erwinrol.com/downloads/software/dmx_usb_module-20040914.tar.gz $:tar -zxf dmx_usb_module-20040914.tar.gz $:cd dmx_usb_module $:make $:cd .. $:su #:cp dmx_usb_module/dmx_usb.ko /lib/modules/2.6.x-x-386/kernel/drivers/usb/serial/dmx_usb.ko (x-use the noted version of your kernel headers) #:rm /lib/modules/2.6.x-x-386/kernel/drivers/usb/serial/ftdi_sio.ko #:cd /dev #:mknod -m 666 dmx0 c 180 192 #:nano /etc/modules
you ad now the following line:
dmx_usb.ko
ctrl (strg) o + enter to save ctrl x to exit nano
Reboot the machine
#:reboot
Starting the Node
Login to the machine with your username and password
Check that the dmx_usb module is loaded:
$ lsmod | grep dmx_usb dmx_usb 11012 0 usbcore 114176 8 dmx_usb,ftdi_sio,usbserial,usb_storage,usbhid,uhci_hcd,ehci_hcd
You should see two lines like above. This shows that the driver has been loaded correctly.
Plug in the Enttec Open DMX USB Interface. Run dmesg and check that the device was initialized corrected:
$ dmesg ... heaps of output ... usb 3-1: new full speed USB device using uhci_hcd and address 5 usb 3-1: configuration #1 chosen from 1 choice /home/simon/dmx_usb_module/dmx_usb.c: DMX USB device now attached to dmx192
Right at the end you should see something like the 3 lines above. This means that the widget has been recognised by the dmx_usb driver.
Start the artnet node by running:
$ artnet_usb
By default the node starts up using ArtNet subnet 0 and port 0, this corresponds to Universe 0 in Magic Q PC
Running artnet_usb with the -v option gives you debug information. The following arguments are supported:
Usage: artnet-usb [OPTIONS]
Acts as an ArtNet to DMX node using the Enttec Open Usb Interface
-a <ip-address> IP address to listen on (defaults to the address
of the first non loopback interface)
-c <config_file> Config file to use for node name and port settings
-d <dmx-device> device for dmx output (default /dev/dmx0)
-p <port-address> port address for output universe (default 0)
-s <subnet-address> subnet address for output universe (default 0)
-v be verbose (prints data for first four channels)
-z Run in a new process (handles widget disconnects cleanly)
The universe address of the port is made up from the ArtNet subnet address and the ArtNet port address. The four least significant bits are the port address, the four most significant are the subnet address.
For example :
$ artnet-usb -p 3 -s 2
sets the universe address to 0x23
Testing with DMX Workshop
Start DMX Workshop and verify that the node appears in the connected devices list.
Using the node with Magic Q PC
If you enable now Artnet Universe 0 in Magic Q from ChamSys, you have a fully functioning one universe DMX512 interface. This works much better than MagicQ alone with the Open DMX USB Windows drivers. You can also use as many universes as ArtNet supports (but at the moment only one Open DMX USB device per node is supported)
