N4-G4-MP3 Director

Recommended Posts

Hi! 

I have a question about N4-G4:

I have about 10000 pixel tree and i want to control it with N4-G4. If i set all 4 ports to "regular" network (not AUX A, AUX B etc.), will it work proper with controllers in my network? Or i should set up each port to it's own network (regular for port 1, aux a for port 2 etc.)

If you are going to get a multi port Director ... it'd make sense (to me) to utilize the features of it. Personally, I'd be splitting into as many networks as possible, just to keep the overhead to a minimum.

Do you *have* to use multiple networks .. no. You could make them all a single network. (*disclaimer: unless they've really, really changed things in the N4)

Thanks. But it’s interesting for me and i want to know:

will the pixels work faster in case of using 4 ports all set up to regular network for 4 pixcon16, instead of using one port for 4 pixcons?

If all 4 ports are on a single network ... then your display will run just as fast (or slow) as if you had it on a single connection.

Why? All 4 ports would be sending out data for ALL controllers on the network. Same amount of data goes out over every port.

If you want to reduce the amount of data going out over the ports (or for those on desktops the USB adapter) then you have to switch over to multiple networks.

10,000 pixels on a single network is way too many.  Split into four networks with all running at 1000k speed, and you are right at Max recommended for those network speeds.  With that many pixels, I would recommend using a computer so you could run as many as 16 networks (if needed).  This is particularly true if there are other things that can't run at 1000k speed.

With the N4G4, you can run up to 16 networks with multiple units.

Remember that the N4G4 has 'Director Link'.  Each director is daisy chained together, so with 5 N4G4 MP3 directors, you can run 15 separate unique networks.  Adding a 6th would allow all 16, as well as 2 additional ports that could be used as 'repeaters'.

We will also have a 2 port G4 director that can be used in Director Link mode (so 1 network is director link, the other is for some LOR network)

Good point Mike.  You could, but at $300 each that would be $1,800 for 16 networks vs $100 - 200 for a show computer plus $512 for 16 USB adapters and less than $50 for some USB port expansion.  I would rather spend the kilobuck on lights or controllers.

Personally I have never understood the appeal of ever using a director.  Using a computer costs less and gives far more capability and less hassle.  About the only place I can see a Director as preferred is if you are running a show in something like a public park there is no practical way to secure a computer (although with micro sized computers, even that is not much of an issue).

What is the speed of 'Director Link"?  Could these be connected together over a ELL?  That would be a BIG + for a neighborhood show

I have an issue with my N4-G4:

I tryed to run my lights using director (made the SD card via HUB etc). And when i put it to N4-G4, it shows "init", during this pixcons stop flashing red (so they have get the network from N4-G4), then director start the show, but the lights doesn't flash. The status led on the director doesn't flash too. The network settings are the same, like on the PC during writing SD card. And playing sequence through PC (via USB-LOR adapters) goes fine. Could it be broken N4-G4? Or i do something wrong?

3 hours before i've created SD card for other N4-G4, but in simple mode (with 1 network on the board). So, i know how to make SD card via LOR HUB. Maybe i've made any mistake during creating SD card in advanced mode...

By the way: I have 4 pixcons with 1820-1860 pixels in each, 1 pixcon with about 800 pixels and the globe with 2000 pixels. Totally about 10000 pixels. And it goes well in four networks (1 of my networks has 3800 pixels).

YES.  Director link will run perfectly fine over ELLs and is one of their main selling points.  I always forget to point that out.

I never said it was cheap :)

I really think it just comes down to personal preference.  Directors make it easy to run 'headless'.  Many commercial customers like them because it is a set it and forget it kind of thing - they stuff the SD card in and at the end of the season just take it all down and put it away.  

It also does take some of the 'geek' away.  It's easier to create an SD card for multiple ports than it is to set up multiple USBs/etc.  

But between you and I, I too would only run from a computer - especially if I had one that is already running 24/7 (like my file server) :)

Yes, there are many commercial customers who would like this. There are times when setting up a computer onsite would be a logistical nightmare. Let's not even talk about getting the network cable back to home base.... :)

I use a G3_MP3 Director to run the display at a local church.  The building that we use to house the equipment is not heated.  December nights in Minnesota can get to -20F.  I feel the Director is a better choice for that environment.

If I get a new N4-G4-MP3 director can I use my existing G3-MP3 (2 port) as a slave?

Right now I would say "no." My guess is there is firmware/hardware involved on the new boards that would make them incompatible with each other.

I could be wrong. Maybe @DevMike will comment later in the week.

It would not gain you anything.  You would tie up one port on each director for the link between them, leaving 3 + 1 equals the same four that you would have with the N4. The only way you would gain is if you used an ELL link for the sync to get across the street for example and then you would have a real high speed source across the street.

I think that is what he is looking for. If not, I am. Can a G3 be used as a slave (ie. connected via ELL link).

From what I'm gathering, the ELL link between N4's is more of a timing signal. Each N4 will have a SD card in it (From what I can tell/recall) that they are playing from. The link between them would be to keep timing in sync so they are all playing the same thing.

I wouldn't think would could do that with an N4 and G3, just based on how I think it works.

That was my initial thoughts also, but I wanted to check.

What is the "recommended" maximum number of pixels that can run on each network of the N4-G4-MP3?

Only Pixcon16's can run at 1,000K at this time correct? Pixies can only run at 500K?

Nope.  According to the LOR network speed page, all the Pixie controllers can handle 1000K speed.
