Looking to make PIXELNET wireless work.
I don't know that much about pixelnet or wireless systems and how they work.
But I would like to look into it. Maybe find some thing that would work.
I put in a call to this company. There going to have some one call me back.
I think this is the company that came up with PIXELNET.

Does any one know of information centers or companies that could help.
Thanks

it's not related,
RJ came up with the pixelnet protocol for smart strings. they don't do wireless...
-
All the PixelNet controllers need 12v and it was designed to use network wire which only need to use 6 of the 8 for voltage. That leaves the other 2 for PixelNet. I think the conductor talking to a slave which can be across the street will use wireless, at least that's my understanding. But it won't be sending Pixelnet only a sync signal.
-
conductor and slave send pixelnet out the rj45 jack, this can't be sent via wireless.
they receive the sync signal via the magjack which is regular ethernet networking
-
OK. Thanks for the information.

i know the discussion about wireless pixelnet comes up often, and i agree that pixelnet protocol will not go over wireless unless RH creates a new device with that purpose.
BUT... I don't understand why you couldn't use a wireless hub and wireless switch to transmit the E1.31 packets from the computer (through wireless) to the EtherDongle. The EtD would then be located in the yard, across the street, etc.
Similarly, maybe (has anyone tried?) the wireless interface that is used to connect conductor/slave [ASUS 802.11b/g/n Portable Wireless Router (WL-330N)] could be used to connect computer/EtD. (The MagJack is compatible with that interface.)
-
i tested the etherdongle receiving E1.31 packets from the pc via a linksys wireless router / Linksys Wireless Bridge. It worked, but i didn't try 1000's of channels.
but in all honesty, the more these channel counts keep going up, the more likely you're going to flood the network anyways...
at least with a conductor / slave, you wont flood the network, and can theoretically run millions of channels. (just in 16k chunks here and there)
-
Now that's a start.
Some questions.
What is the E1.31 packets? Is that the pixelnet information before it is decode to pixelnet coming from the PC to the ETD?
If that is right that is sending e1.31 threw the wireless router to the ETD.
Can that work with the basic pixelnet dongle? That can use 4096 channels. If I read the pixelnet dongle right you can add on to ss hubs with 16 smart strings and keep going on.
Just have to know how much channels your can send.
And if it is limited then maybe you can just copy of the same sequence to other shows. A repeat.
Like other houses. Or people. Cars or horses like I do. Maybe people.
This may be a dumb question but why can't you send the data information coming out of the dongle threw wireless?
-
Wireless Ethernet works great as long as you have a good wifi signal.
This is going to be a lot of hardware for sittinguphigh's application...
You need a small PC running your scheduler, a wireless wifi hub, etherdongle, pixelnet hub, SSCs, and smartstrings on the lead horse.
An wifi unit set up as a bridge, etherdongle, pixelnet hub, SSCs, and strings on each of the other horses.
You also need lots of batteries...
Based on his earlier posts, this is going to be way over budget as well.
-
Why can't you send the data coming out of the dongle through the wireless?
Currently there is no device that we know of that is compatible with the data being sent out.
The wireless device would have to be capable of handling a 1Mbps data stream with 8 bit serial words.

This device does Wireless Serial data, and almost reaches 1Mbps speed, but it costs much more than I'd be willing to spend for something that still might not work:

Using a true serial device then brings up the complication of using multicast. to reach all of the horses, you need multicast. Multicast is used by RJ's E1.31 protocol to reach the EtD, but downstream from the EtD the protocol is NOT multicast.

Wireless Serial data what would that compute in channels?
I did see some of these with board only for 11.00 to 25.00 dollars on ebay.
If these are the same ones. Not multicast but it's a option.
http://compare.ebay.com/like/321051817034?var=lv<yp=AllFixedPriceItemTypes&var=sbar
This could work for multicast to houses next to you. All one show.
If your neighbors have Christmas lights your just add them on.
With very little cost to them. Just extra wire and a wireless board. You may need a hub.
But keep the cost down for them. Be more willing to join in.
Or have the whole show with people walking. Wow that would be cool.
You could do caroling this way.
With Cars the same way. The car music people would love this.
A mobile Christmas show. Go were the people are.
Your children would love it to use this for school or church Christmas functions.

The linked product can only handle 1/10th the data rate needed for a wireless Pixelnet. The conductor/slave is the envisioned solution. If you do not like that method maybe use E131 with routers but that defeats the purpose of minimizing the network traffic to just a sync packet with conductor/slave.

Lead horse: EtD with Conductor-daughter board, active smart hub, power suppply, ASUS wireless router, SSCs and strings.
Partner horses: EtD with Slave-daughter board, active smart hub, power suppply, ASUS wireless router, SSCs and strings.
With this, each horse has 4096 channels and all horses are coordinated with the others. You are limited only by the amount of battery you can carry. Heck, add more hubs... or even double up the entire setup to get 32,768 on a horse. ;)

each horse has 16384 channels (4096 per leg, er.. i mean universe)

I found some zig bee modules that come close (921 Kbps), but they still won't carry a single pixnet universe at full speed.
Most of the stuff I've looked at so far only supports serial protocols to 115 Kbps.
How to relate bps to #of channels?
It takes 10 bits to represent one byte of pixelnet type data (1 start, 8 data, no parity, 1 stop). This is 1 channel, but it takes 3 channels to control 1 node.
There is also a synchronization sequence that has to be sent so that all of the SSCs know to reset their channel counter for the first channel of data. After that the counter is incremented by one for each byte of data received...

if you had (4) smart hubs, (4) power supplies, etc. then you'd have 16,384 channels.

OK then I can use as many daughter boards as I wish with the conductor as main data.
And if I'm not using more then four SSC then I only need one 4 port hub.
Look back on the conductor coop the daughter board complete was only 39.95.
ETD 94.00
CONDUCTOR DAUTHER BOARD 40.00
HUB if more then one SSC 12.00
TWO STRINGS of 100 nodes 80.00
WIRELESS UNITS 20.00
12V 9AMP BATTERY 19.00
Total being 265.00
Not included tax and shipping
Using only one SS of 128 nodes would be 232.00
I will have to see if I can sell that to my riding friends.
I think it will help to build a demo on my horse.
If any one thinks another way.
Considering cost and space let me know.
-
You should check to see if everything will run from 12v. The EtD and wireless could run in different voltages.
I was assuming that you'd have a computer battery UPS with 110v to run everything.
-
Just spitballing here...
If the issue is that you don't have enough bandwidth to carry pixelnet outright because of flooding the network, what if the pixelnet were converted back to E1.31, sent over a wireless, and decoded at the other end.
Would that make a difference in the amount of data, or at least the packaging of the data, being sent?
Latency might be an issue with the conversions...
Cost Issues? A conductor/slave setup vs a reverse-EtD/EtD?
Other Thoughts?

I think the question would be is there a different between the DMX and PIXALNET E1.31
that you could not send the PIXALNET E1.31 threw wireless before the dongle.
I would think if that could be done RJ wouldn't have to made the CONDUCTOR DAUGHTER BOARD.
But maybe some one else could explain that in more depth.
-
Each EtherDongle has an RJ45 jack (plastic), and a MagJack (metal)
the plastic jack connects to your lighting hardware, and with pixelnet, this will not do wireless.
the metal jack will work with wireless (it's a regular network connection) and can be used to send a sync timing signal between a conductor and one or more slaves.
your problem is powering all of this gear on a horse.
-
I could use a portable unit but It's the cost fact that I'm trying to fix.
The daughter conductor would be close to same price as the portable wireless unit.
The deal would be to not need a ETD or the cost factor for the other horses.
