SOLVED!! - no results with Vixen->ED->LE

[mmorlan62]

Can anyone comment on the E1.31 packets I've posted to this thread?  If Vixen is outputting E1.31, I'm not sure how I could be failing with my setup.  It's not that complex.

Michael, when I get a chance this weekend I will capture and post the data packets of Vixen communicating with my ED controlling a Lynx Express

[mmorlan62]

caretaker,

Excellent.  Then we can compare yours against the ones I've posted here and against the E1.31 spec.

Best,

Michael

Ok below is a packet capture from Vixen 2.1.10 to the Etherdongle: I was running the attached sequence which is 2048 channels of which I have 16 set up randomly flashing. My Lynx Express picked up the data and flashed it 16 led's in the random pattern. I am running this on my show computer (Windows XP - Athalon XP 1800+ 768GB Ram) to a NetGear FS105 fast switch (which the ED is connected to) which is connected to a Net Gear RT311 router which is multicast capable.  If you PM me I will give you the complete wireshark capture and the vixen file if you want them.
Some notes in setting up Vixen with the ED, make sure the ED is plugged in and connected before opening Vixen and setting up the the output plugin in your profile. It should look like this:

Jeff,

I'm not sure what the pixelnet.dll plugin you linked to in a previous post is about.  It was seeking a COM port and was definitely not talking to Ethernet.

Here are the E1.31 headers from your EtherDongle packet and mine.  Why, I wonder, do they bear absolutely no relation to each other?

According to the draft E.131 standard (E1-31r3.pdf) your header isn't formatted correctly.  How is your EtherDongle even working?  (For instance, the ACN Packet Identifier "ASC-E1.17" should run from bytes 4 through 15, and the Source Name should run from byte 44 through 107.

Even weirder:  Why does the About dialogue of my Vixen read as version 2.1.4.0 but the latest version available on the website is 2.1.1.0?

Hi Michael,

Have you tried the old version of the output plugin yet?

[mmorlan62]

I've tried ver 1 and ver 2.

You probably updated, that's the latest update, why it isn't shown on the website, I don't know,

Bill

[mmorlan62]

Okay, I've shipped my ETD and LE off to Rick Perry aka. rmp2917, who is being kind enough to scope and probe my boards.

I'll report back his findings (if he doesn't himself.)

Regards,

Michael

[mmorlan62]

SOLVED!!

Rick aka rmp2917 discovered a solder bridge between pins 40 & 41 of the Ethernet chip. A little flux and solder braid and the bridge was removed and the board functional.

Here's Rick's troubleshooting procedure in his own words:

"To start with, I setup my equipment to provide a known working test bed. Since I have 2 ED’s, I have one setup for PixelNet connected to a smart string and one for DMX connected to a Lynx Express. I used xLights to test the units. It was easier to setup and use the test panel instead of using Vixen.

"I connected your LE in place of mine and everything was working fine. Each of the channel LEDs responded according to values I was sending from xLights. I connected a string of lights to all 16 outputs to verify that they actually lit.

"Now that I knew the LE was OK, I moved on to the EtherDongle. I placed your ED in place of mine. Everything appeared to be working. However, there was no response from the LE. At first I thought there may be an issue on the output side, so, I made an adapter that allowed me to connect the LE on universe 4. I got the same result.

"The Ethernet chip seemed to be receiving data from the PC since the LEDs on the jack were responding appropriately. Also, the PIC seemed to be sending data to the LE since the data LED on the LE was lit. Also, after removing my ED, the channels were still on and as soon as I plugged yours in all channels turned off. This led me to believe that there was an issue with communication between the PIC and the Ethernet chip. So, I started checking those connections.

"I found that pins 40 and 41 of the Ethernet chip seemed to be shorted. The resistance on yours was 0.9 Ω while the resistance on both of mine was 6 point something MΩ. I looked for possible shorts on the board, but could not find any. So, I started looking at the chip itself. It looked like there might have been a little solder between the pins, but it was really hard to tell. I used a flux pen to add some flux to the pins. Then, I used solder braid with a fine tip on the soldering iron to remove the solder. The resistance between the two pins was now 6 point something MΩ.

"I reconnected the ED and ran through the test again. Everything was now working and the LE was responding as expected."

So, there ya go.

A big huge shout out to Rick aka rmp2917 for his most excellent service, not only to me, but to the DLA community.  If it would serve the site, I'll write an ETD troubleshooting guide based on the experiences of this thread and Rick's work.

Best to all,

Michael

[urthegman]

Glad to see you got it working! I was following the thread and hoping you would get the problem resolved!

[rm357]

Congratulations! I'm glad you got it fixed.

Was your etherdongle from the first coop (last year) or the recent one?
There was some trouble with the SMDs from the first coop, but I was thinking those problems were eliminated in the second coop.

Also I feel compelled to give the general warning - messing with the surface mount components should be the last resort when all other possibilities have been eliminated. Most of us do not have the proper tools and it is really easy to damage the chip such that it cannot be repaired.

While it seems like the SMD is the major issue, it really is not - It just gets the most discussion. For every SMD related problem, I would be willing to bet that there are 50 other issues that are resolved by the individual without ever posting. Things like solder bridges, chips in backwards, cold solder joints, wrong component, etc.

RM

[mmorlan62]

Thanks RM.

This ETD was from the most recent coop.

That's a good point regarding frequency of SMD soldering issues.  There are so many tests we tried as part of this thread before resorting to suspecting the SMD.  Anyone troubleshooting a board should start with a thorough review of their build, assuring they have everything soldered in the right place and orientation and that all soldering is clean.  (For example, I had soldered sixteen resistors on the LE board before realizing they were in the wrong place.  So, check and check again during your build.  Then check again afterwards.

I think this thread is a great encapsulation of the ETD troubleshooting process and should serve as a fine source for a troubleshooting manual page in the Wiki.  Would it be of value for me to format a troubleshooting doc from this thread?

Michael
