Native DMX Devices

In addition to Light-O-Rama controllers and various other types of controllers, Light-O-Rama can control native DMX devices, either directly over a serial port and adapter or over ethernet via E1.31.


When you add a DMX device to your display, you add the controller's channels as props in your preview using the Preview Design window.


Several DMX universes can be used, each having a unique universe number from 1 to 999.  Each should be assigned a separate DMX adapter (such as an ENTTEC Open DMX USB adapter) or else E1.31 settings (such as IP address and port).  You can assign adapters or E1.31 settings to universes via the Network Preferences program.


Unlike other protocols (such as LOR), 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 Sequencer 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 or E1.31 address 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.
