Visa light programming with USB DMX Interface

[MAGI2]

Hello!

We are students from Sweden and we are working on a project. We are using 4 RGB COB LED spotlights (programmable with 3 or 5 channel DMX512) in serial connection and these lights are connected to an USB DMX Pro Interface from Enttec. We run the driver from FTDI (its now a COM Port) and we want to program the lights (turn on/off and color selection in fast speed). The programming should be done in LabVIEW (version 2013). We know that we  have to use Visa to communicate with the USB Interface.

1. We want to start and we want to know the basic idea and structure of programming lights using LabView and Visa. How can this be done?

2. When using Visa how we communicate with DMX channels?

Any answere will be helpful to start.

Thank you!

I never used the emttec but other dmx controllers.
Build a string in labview and sent it to the dmx controller.
In essence each led is a 8bit value, and all values are sent after each other as one character.
The best is to use a byte array of values and to convert it to a string before sending.

Duplicate thread.  I think this is the appropriate place so continue here.
