I am aware of RDM but are there any other types of control similar to this? I know that High End Systems create a Talkback system, but are there anyother types of bi-directional control?

Thanks

Thanks for the guide – So would DMX be something we could look at for our local highschool stage or is it a bit beyond basic stage lighting, more focused on professional setups?

Thanks for that, Callum. I love the fact that OSL readers feel that they can help each other out. Your info is spot on. Raghav got in touch via Facebook and I sent him the link to the DMX guide.

Not 100 percent sure about his but i’ve always been lead to believe that DMX means digital multiplex, also known as DMX512 owing to the fact that 512 channels of control can be achieved with a single control cable.

Most intelligent fixtures use more that one DMX channel for operation
e.g

Address 1 may control the horizontal movement on Wobbly Bucket 1
whereas Address 2 may control the vertical movement.

Usually it is only nessescary to set the DMX start address for each fixture (in the example above #1) as the assignment of each parameter to subsequent addresses is handled by the fixture parameter file.

Hope this helps. Rob can probably explain it better than me.
