Dmx pinout - update

[michaelc]

I don't have access to the wiki, but I updated the DMX pinout table and thought I would share it. I know I was originally very confused when all the different boards say they send out "DMX".

I hope this helps and if so, feel free to update the WIKI protocol page.

Would you like a a wiki account to upload your chart Michael? If so send me a pm and I will make an account for you.

Nice job on the chart!!!

I've updated it on the wiki, enjoy.

Pretty sure the JEC pixel pinouts and the Renard pinouts are inverted on this chart...

For a triksc its definitely the wrong way around. Data+ is pin5 Data- is pin 4.

[michaelc]

Timw, I've confirmed all but the REN and PIXEL. The pixel layout was just copied from the original chart on the wiki and I have no experience with it. (Note, I did update the 5pin std to correct the channel 2- pin as well as add the LOR +9V pin)

As to the REN, depending on which board you have the pins are flipped. I'll add a second column for another set of REN boards and footnote which board is in each. I think this is probably the source of much confusion for those trying to learn. Here is an excerpt I found in one of the REN wiki documents:

"This cable will work with Renard16 and Ren-C, but will not work with Renard8 or Renard24, because pins 4 and 5 on the RJ45 are transposed on those two boards. "

also,

"PC to Renard24 LV Cable
PC DB9 Pin 3 to RJ45-pin 4
PC DB9 Pin 5 to RJ45-pins 1,2,5 (pins 1 and 5 are required, pin 2 is optional)."

BUT 2 lines later:
If you are using a RS-232 to RS-485 converter, the pinout is Pin 5 to A+ and Pin 4 to B-. This is the same as for the Ren 16.


It's about as clear as mud. If one of the more seasoned folks would like to jump in and clarify, I'd appreciate it. I think once this chart is complete, it will be very helpful to all.

I know for sure Renard (at least Ren24/24LV, RenxxSS and Ren48LSD) and LOR are swapped between Data+ and Data- lines.

[TimW]

Yep I think for most Renard boards its Data+ to pin 5 on the RJ45.

BUT... the wiki... ( source of all truth... and all versions of the truth... :) ) does suggest that Franks Renard24 is wired the other way.... (http://www.christmasinshirley.com/wiki/index.php?title=Renard_Standard_Setup) I think this is the problem because it looks like it changed from Version 2.5 to version 3 (http://www.christmasinshirley.com/wiki/index.php?title=24_Channel_Renard_with_SSR_Assembl y_Instructions) by the looks of things...

Yep.. its still confusing even after all this time.... The challenge of DIY I guess!

Going way back in time the JEC pixel pinouts are outlined in the schematic here (http://www.doityourselfchristmas.com/forums/showpost.php?p=4419&postcount=5) and here (http://www.doityourselfchristmas.com/forums/showpost.php?p=7972&postcount=2) .. although in this crazy RGB pixel world this maybe only of historical relevance !!

I agree michaelc looks like there are a couple of errors in the stuff thats out there... has the source where you got the pixel and Ren pinouts been updated as well?

Budude,

The LOR info is right out of their DMX Doc.

"Connecting the LOR Unit to the DMX Universe
Light-O-Rama networks are usually wired using standard CAT5 (CAT5e) patch
cables. The cables are wired straight through. To connect a LOR Unit to a DMX
universe you will need an adapter. Most commonly, DMX hardware uses XLR
connectors.
LOR / DMX Adapter Pin Connections

RJ-45 Pin => XLR Pin
4 => 3
5 => 2
6 =>1
A more detailed explanation follows."


see: http://www.lightorama.com/Documents/DMX-DOC.pdf

[TimW]

I think that is consistent with what budude is saying... that LOR pinout is the opposite to Renard.

Renard
RJ-45 Pin => XLR Pin
5 => 3 Data+
4 => 2 Data-
1 =>1 Gnd

[mschell]

And having wired up some Renard and LOR controllers in the same "cabinet" for the 2010 display, I can confirm that Pins 4 and 5 are definitely opposite between those boards as far as D+ and D-.

[michaelc]

Ok, folks, I've checked out ALL the schematics for the listed boards and updated the table. I'll add to the wiki but let me know if I'm still missing anything.9387

Updated image on WIKI, I did have to resize it by 20% which makes it a touch blurry but it's still readable.
