Native DMX Devices

Top  Previous  Next

In addition to Light-O-Rama controllers and various other types of controllers, Light-O-Rama can control native DMX devices.

 

To set a channel to use DMX protocol, set its device type to "DMX Universe".  You can then set its universe and address (similarly to setting up an LOR controller's network, unit, and circuit).  This can be done in the Sequence Editor's Channel Configuration Screen or in the channel's Channel Settings dialog.

 

Up to sixteen DMX universes can be used.  Each should be assigned a separate DMX adapter (such as an ENTTEC Open DMX USB adapter).  You can assign adapters to universes via the Sequence Editor's Network Preferences dialog.

 

Unlike other protocols (such as LOR or X10), the DMX protocol requires that the LOR Control Panel be running in order to actually control the devices.  The LOR Control Panel will, in turn, start up the LOR Comm Listener.  When a program such as the Sequence Editor or Show Player wants to send a command to a DMX device, it actually sends the command to the LOR Comm Listener, which in turn sends it out over the adapter assigned to the device's specified universe.

 

Note that you do not have to use the "DMX Intensity" effect on DMX channels.  You can, but you can also use any other effect (such as Fade Up or Twinkle).  If you use a DMX Intensity effect, it will have a natural DMX intensity range of 0 to 255.  If you use any other effect, it will have a range of 0 to 100, but Light-O-Rama will automatically scale it to DMX's 0 to 255 range immediately before sending it out to the actual DMX device.
