TM1804 Chip string not lighting up

So I'm trying to transition off of some of the old DIYLA equipment.  I have a set of pixels that have a TM1804 chip in them.  My old smart string controller (falcon firmware) controlled them.  I tried to hook up to F16v2R, set the port the TM18xx, tried test mode but can't get them to light up.

This is the old string.

Any ideas/suggestions?


I am still using mine on a F48 and they are working just fine.  Make sure that you have them hooked up correctly and that the controller is supplying them with 12V.  


@tbone321 Thanks.  That was it.  Apparently I decided to use a different wiring configuration on the connectors some 7+ years ago.  Didn't even think to check that.


I'm still using Tm1804s with Falcon controllers.  And I vowed that this year I would finally convert all of them from the old DLA wiring scheme to the current EU wiring that all the vendors use.  Still got a bunch of props to do before Christmas.  I got all my gutter lights done and put up for Halloween then converted my verticals that connect to the ends of some of the gutter lights and realized I had not converted the ends.  And the gutter lights are all up and working.  Guess who will have to take them down after Haalloween and fix them before Christmas.  sigh.

@jnealand I went back to the DIYLA wiki and then realized what the problem was based on tbones suggestion.  I only converted 1 string for Halloween.  My strips in my tombstones are too much of a pain, so I pulled out the old smart hub and am using that and will continue to use that I guess.  I haven't decided on Christmas props yet.  Luckily it is only 5 strings and 1 strip of of the hub which I could run off of my existing falcon16.  My megatree is powered by a zeus that I don't have a replacement for yet.  Guess that will be next years project.  While my Zeus still works, starting to get flaky.  Once in a while I need to go unplug/plug a string back in to get it to "unlock".  Still not bad for 10 year old DIY soldered equipment.

Anyone know what happened to RJ?
