Frustrated to say the least....
« on: January 21, 2012, »
O.K. I know I'm a little late in the game of RGB but it's down time right now and I can play around with it and experiment.  Well I spent the last 2 hours doing just that and go no where.    Once I finally found the information in regards to the power supply for the pixelnet hub I got that powered up.  Although if I had seen the 12 v when ordering my parts I would have just used my 40 amp regulated power supply I use for HAM radio but I didn't see that until I was putting the parts on the board.  go figure my luck....

So I spent the last 2 hours like I said...  I changed both by lynx dongle and etherdongle over to pixel net and gave it a whirl.  yup fast spiral downwards I went.  Can't get DMX out of that thing to save my life.  Re-flashed both numerous times just to make sure.  Re-flashed the hub just to make sure.  NOTHING.....  Finally threw it all in a box and gave up....  I was so hoping this was going to work for me.  Now I'm stuck with some samples from HolidayCoro (yes I know now that they are dumb modules and basically DMX only - NOW.  Took me foever to find that thread to read and I think I found it on another forum).

Anyone else having these issues?  It's suppose to send out DMX with PixelNet but mine isn't.  If I had some smart strings I'd attempt my SSC's to see how those go but I just can't justify the cost of shipping.  That is just unacceptable in my book.  Esp. to China.  Won't do it.  Someone here in the U.S. must be doing these.  Can't believe no one is.  Just giving China a tighter grip on us than what's already there.

My suggestion....  a wiki update that has all the information in one spot so it's easier to find.  That was more than half my time today searching through all of the threads and reading the wrong stuff before the right stuff presented itself.  It took me forever to find how to setup the EtherDongle with DMX initially.  That info. was also buried deep in threads.  Just don't have the patience today to mess with this anymore.  Frustrated doesn't help either.  I'm not an idiot but this can't be that hard to do.  I've already done two complete shows with DMX now... :(

Dean,

Sorry to hear about the problem.  It's probably best to step away for awhile and then pick it back up later.

First I have a few questions about what you know works and what is new and being tested for the first time and take things one step at a time.  Probably elementary questions but we need to start somewhere.

1. Was the Lynx USB dongle used in your show and was it flashed with DMX; i.e. you know the dongle hardware is good with DMX?

2. Do you know if the Etherdongle works with DMX?

3. If the answer to both of the above is yes, then you know the hardware is OK.

4. I'm assuming that you are using cables, USB and cat5 that you know are good and you used previous then the cables are good also.

5. After you flashed the Lynx USB dongle with PixelNet and you get it connected back up to the computer does the red LED light up?

6. If you start up the software and transmit some data to the USB dongle, can you see the green LED flicker?  The green LED might be very faint so look carefully.  I could only see mine in near darkness.

7. If you can see both LED's then the data is probable being sent to the PixelNet active hub.  Thus the data is getting to the PixelNet active hub.

8. Is this the first time you have done any testing of the PixelNet active hub?

9. I'm going to assume that the answer to question 8 is yes based on your comments.

10.  You said you flashed the hub with the PixelNet firmware.  Did the checksum match what's in the Wiki?

11. I believe one of the main purposes of the PIC on the active hub is to do the conversion of the PixelNet protocol to DMX so getting the PIC flashed is paramount to getting DMX out of the active hub.

12.  Are all 3 jumpers on the active hub set to 1?  Both PixelNet pins and the DMX pin.

13.  Does the green LED on the active hub light when power is applied to the board?

13.  Double check the direction of the 485 chips because one of them is used to transmit data to the DMX RJ45 plug.

14.  If the PixelNet active hub is new and being tested the first time then pictures of both side of the board would be a next step.

Once we get these answers we can then move to the next step.  Hang in there there are lots of people to help out.

Yes it was.  both used and flashed with DMX.  Was used for both my Halloween display and Christmas one.  It is good.

All three (3) jumpers are on 1.  Green light on the hub does come on.  I have over 11 volts on the 12v option side too.  So power isn't a problem from what I can tell.

Chips have been verified.  I've checked for solder bridges and cold solder joints too.

what are you using as the power source of the active hub?

An older AT style computer power supply.  I don't have the 12 volt option yet otherwise I'd be using my bench power supply of 35 or so amps.  I'm not running any smart strings so the 250 watt should be enough.  Or I'd think so anyway.

how are you plugging in the connections, just using the 4pin hard drive connectors?

Just curious since I didn't see it mention but did you change the software package to send out the pixelnet data ?

Example you can't use DMX Deck with a dongle programmed with pixelnet while it works fine when the dongle is program for dmx.

Using the 20 pin connector plus the 4 pins like it stated in the wiki.

Yes I changed vixen and xlights both for pixelnet.

ok, when you said AT power supply, it threw me off, they had a different connector than atx.

when was the last time the power suplly worked?  something those things can have a good feed on one voltage rail, and then a bad feed on another voltage rail.
yellow 12v+
red 5v+
black -
i forget the color for the other voltage...

You might want to try the test feature of xLights. It was a big help to me when I was struggling getting DMX out on my SS Hub
80 Channels LOR, 112 Channels Lynx Express
16 Channels MR16 with 5 Mighty Mini's
2 SmartString HUBs
LedTriks
5,000 LEDs lights, 50,000 incandescent lights, 3,600 RGBs
30 Strobes
15 Snow Lights

I'll check the power at each wire tomorrow after I get some sleep.

I've done the test feature out of it.  Funny thing is that when I go and plug the cat 5 cable into a pixelnet jack the lights respond.  not fully but they act differently so there is something coming out of the board.  Just not DMX.

So z327 I'm not the only one having issues.  Makes me feel better...

I think this power supply is labeled for each color.  I'll take a look at it closer tomorrow though.  I'm not sure when the power supply was running last.  I'll have to do some checking and see.  If I had the 12 v kit I could just by pass all this and have one less thing to troubleshoot.

I was in your shoes. Was beginning to think I was too "dumb" to use "smart" strings.   ;D  To me the frustration stemmed from needing to glean all over this place to find essential snippets of ss tips.  One day later after a breather I had blinky.  You'll get it give it time.
Sam, who is happy he flashed his etherdongle with newest firmware!

Well I think that is the problem.  There is so much spread out everywhere on here that it's tough.  All of this info. needs to be located in a central location that's for sure.  Don't always have time nor do I always want to read 60 posts in a single thread.  Just poor time management IMO.  And it drives me nuts that I can't pull up the same info again when I need it.  Have to sift through those posts again to find it.  So frustrating.

Today I've been working on my sample packs I recv'd from Holiday Coro and discovered issues with them.  So maybe I can get back to the hub now and see what I can see. :)

the wiki is available for anyone to setup this stuff. just let Rick know. its too much for one person to update everyone. I'be helped out myself on things in there.

chrisatpsu:  good to know..  I'll have to see about that then..  Wasn't fully aware we could do the wiki.  As I get answers I'll have to jot 'em down and get organized.  Thanks!


O.K. UPDATE:  reflashed checked voltages etc.  Here is what I came up with. No DMX out.  NONE!!  Hooked up an LE and no data to the LE.  Not until I plugged the LE into a pixel jack.  Then the data light flashes like wildfire...

And to answer a question I'm currently us a Lynx Dongle (not ED) flashed to pixelnet.  Gonna re-download the hub hex and relash again just for grins and giggles....

So now what?  Oh yeah the voltage on the board is just over 11 volts.  Not sure how critical this 12 volts is but I'm above 11 but less than 11.5 and I'd say average 11.2 VDC.
