Matt,

Did you ever get your LED mis-fire problem fixed?

David,

RS232 is a serial port. Phil is correct in that there is not enough current to run the system from any rs232 port either old or new. As far as logic signal levels the LedTriks is strickly a lpt setup it does not use a rs232 port at all. It is the lpt port that we are concerned about the signal voltage on. You should not have an issue on any lpt port if using the allegro chips I have been recommening for quite a long time now. by using the correct componets there should be no problem with any port that is functioning correctly. The next Ledtriks setup I am working on for next christmas will be on a different setup all together so it will not need the lpt port but will be more expensive to build as it will be full color.

Hope this helps.

Wiki Notes
Now that the Wiki is here, building / Updating an external doc is no long needed. Also you don't have to ask permission to add / update the wiki. The wiki is owned by everyone that contributes to it. Also if someone doesn't like your changes, they will update your work. Thats where the wiki power comes in.

Cable Notes
You mentioned that you were building the cable. I hope you aren't spending much time on it (maybe you are already doing this?). This is how can build the cable in 30 seconds:

Mouser #601-40-9588M

Use a DB25 Male to RJ45 Connector. I didn't use this exact one, I have a pile of them from various other project. All you do is push the pins from the RJ45 plug through the holes of the DB25 plug (based on the wire pin out on the PCB) and you are done. A normal cat-5 patch cable is then used between the connector and the LedTricks board. Easy Easy!

Matt,

I ordered this part and have been trying to integrate it into the design as you proposed. The problem is that the pins out on page 9 of the .pdf draft version list NINE connections ... the CAT-5 cable only has eight (as well as the modular plug on the afore-mentioned product you listed as a link). So, I contacted one of the tech guys at Allied Electronics, showed him the .pdf draft manual, and this was his response:

"After reading your PDF file this goes to the Parallel printer port on a PC and that is a 25 pin female (on the PC itself) which requires a 25 pin male connector

The part you've asked about is a female
The Allied number 510-3161 is the male version

But there is a problem I don't understand how to get around

The RJ-45 connector uses 8 pins
looking at your DB25 connector pin-out on page 8 it uses 9 pins
I can't get 9 wires into a 8 wire connector.

You might want to ask the group that's doing this project how they accomplish this.

ANY HELP AND/OR FEEDBACK WOULD BE APPRECIATED!!!

I WAS ABLE TO GET A HOLD OF THE DATA SHEET FOR THIS PRODUCT (WHICH SHOWED THE PINS-OUT), SO WE'RE IN BUSINESS! A BIG THANKS GOES OUT TO JIM BEARD FROM ALLIED ELECTRONICS FOR RESEARCHING THIS PRODUCT AND ACQUIRING ITS DATA SHEET FOR ME!

A MUCH CLEANER LOOKING INTERFACE CABLE IS IN THE WORKS ... WILL UPDATE THE WIKI FILE AS SOON AS IT IS COMPLETED AND TESTED.

Not yet. I moved it around a little while working on something else then discovered some other issues. I am sure I have a couple bad solder joints. Will throw some more time at it soon.
