Lynx Combiner

[RJ]

This is the little pcb I did to let me hook up to 4 dongles together and make a pixelnet feed for all 16,384 channels of a pixelnet multiverse.

I am going to have a little coop for them soon and get some made. They cost little and only take five rj45 jacks for parts. I am doing this since some users are going to use multiple dongles this year and it will help them get them out in one cat cable to the hubs.

Wow thinking of everything.

Nice RJ

RJ;

When will the PCB's be available?   or  better yet

When will a CoOp be starting?

Thanks Much

I'm confused - I thought the Ethernet Dongle was going to handle 16k channels?

[batdive]

TNG -

Your right, but since that will probably not be ready until next year, RJ made the combiner so you can take 4 regular Lynx dongles (reprogrammed with PixalNet) and combine them into 1 CAT cable instead of having 4.

This looks to be in lieu of a pixel net dongle (no release date yet).  The purpose is to take the output from four regular dmx dongles and combine the signals to be carried from the combiner on one cat5 cable to the daisied pixlenet hubs.   Without this, you'd have to have individual cat5 cables running from each dmx dongle all the way to individual hubs, none of which could handle more than the 4064  channels (1354 nodes)  a single dmx dongle can output.  

Ethernet dongle will make this superfluous.... once it hits the streets.

the output of 4 Lynx Dongles (with upgraded firmware for Pixelnet)  supporting 4096 channels

I will coop the pcb as soon as the new passive 4 port hub prototype pcb is here and tested. They will be on the same coop.

woot! woot!

I know how this combiner works with pixelnet by taking 4 - 4000 channel networks and combining them into one 16000 network. My question is can this combiner be used to combine DMX universes so you have 4 dongles with 512 channels each go in to the combiner to make 2000 channels of DMX. Thank you in advance for thinking over my question.

Hi Adam

The combiner really is designed for the Lynx USB Dongle. The dongle firmware determines if its using pixelnet or DMX.  The only gotcha is the other end of the cat5 cable which is suppose to be connected to the 16 port SS Hub. Just thinking out loud you will have to split the 4 pairs of the cat5 cable for each dmx universe.

Or I could be totally wrong

I see where this is going - if you used 2 combiner's so dongle 1,2,3,4 => combiner => CAT5 => combiner = Unv 1, Unv 2, Unv 3, Unv 4

All it is doing is utilizing the wiring ... it is the same theory the SS-Hub is using.  But I may be WAY off but makes since as I type.

Each connector on the combiner connects its pins 1 & 2 to a different pair of wires in the combined cat5 cable. If you put a combiner on each end, you should be able to trunk 4 dmx universes over 1 cat5 using the second combiner as a splitter. The only question is whether or not crosstalk between the pairs could become a problem on a very long run... (like across the street or down the block)

I doubt that cross talk is going to be much of an issue with CAT5.  If it were CAT3 or flat phone wire then I would be concerned but not with CAT5.

[RJ]

Cross talk will not be an issue as they are each on their own intact pair.

I love seeing you guys start seeing the big picture!
