Dmx In Slow with Enttec Pro?

newton2013 · May 16th 2012

Using 2 Enttec Pros and a Madrix Neo.
Tried a bunch of configurations, the DMX Input is way slow either way.

Madrix Neo (out) to Enttec Pro #1 (in) to DMXC to Enttec Pro #2 (Out)

DMXC to Enttec Pro #2 (out) to Enttec pro #1 (in) to Madrix to- Neo (out)

With both programs, Dmx Input (and throughput) is slow.
Enttec pro's are both set to highest frame rate via ProUtility.

Anyone know if there is a specific frame rate that I need to set the Enttecs to?
I've searched the net but have found no information.
I'm guessing I must be missing something simple...

I don't think that the problem is the framerate.

I think because you use Madrix many channels change at one time.
Everytime the interface sends a packet over usb to the pc I'm telling DMXControl what channels have changed.
So the Plugin don't accepts any new packet until this is finished.
Because you change alot of channels at one time, it takes "some time".

I will try to make a new version wher the input is written into a buffer and a timer pereodically tells DMXControl what changed.
This is maybe a bit faster.

Try this version and tell me if the speed is better.

Swapped in the new drivers, looks about the same. Hard to tell.
For use of 2 enttec pro drivers, I am supposed to slightly rename a copy of the file and load it into the same folder, correct?

DMXC generated levels are fluid, Dmx thru is maybe around 4-5hz/4-5 changes a second

This is also occurring when I put dmx in to madrix though, madrix also displays DMX In at same 4-5hz-ish rate.

Both madrix and DMXC output straight at a perfect fluid rate on their own Via neo and enttec pros.

Although Cpu and Memory on the computer are fine while running, Should I not be running both programs from the same computer?

Also, should the enttec drivers 'UBSSERIALPORT' remain at 9600,N,8,1 in computer's settings?

Thanks for your time!

Could you make a small video where I can see the problem?

Do you mean with slow that the sample rate is to low or do you mean that there is a delay between change and display in DMXControl.

The sample rate. Here is a shaky video showing madrix out (3hz purple strobe w/fade effect), DMXC with some red and blue channels thruputting from madrix, and DMXC controlling pan and tilt.

I cut back the number of DMX IN channels for troubleshooting.

No commands are missing, I just took a bunch of channels out of the softpatch.

Same rate occurs when the DMXC Effect that is running pan and tilt is Off, although it is on in the video.

This is really a bit slow.
The version I posted here should be able to take 20 samples per second.
I will try to find out where the problem is.
In my tests with a small lightning desk looked a lot better

I don't know where I could improve the outputplugin.
The only way where the performance could be better is to use the direct FTDI API.
But for this I have to completely rewrite the outputplugin.
Because I have to use VB6 its not so easy as in C# for example.

When I have sometime maybe I will try to rewrite it.
