for reference the diyla smartstring controllers use a 120ohm resistor

What happens if you sacrify the first chip 1804 placing him the shortest as possible after the output of the PixAd8 (2/3cm not more)?
Don't each module regenerates the clock and data from one to the next one?
I remember i do that with the 2801chips, where i had similar problems rear the TP last year
This solves the problem and found i can reach maximum 6 meters from 1st module to next one and so on.
But the first one direct attached to the TP for clock and data regeneration

Yes, this definately works, and will probably be the solution for now. I just think that Ed would prefer it to get a bit more than 3-4cm to the first pixel!riri7707 said:Hi Kane,

Just a quick followup for anyone that is interested.Kane said:Yes, this definately works, and will probably be the solution for now. I just think that Ed would prefer it to get a bit more than 3-4cm to the first pixel!
I've actually worked out that I haven't broken the outputs my modifying them with a 120ohm resistor - they actually still work, but instead of working at any speed (1600,2000,2400), they only work at 2000 (which is actually the correct speed for 1804)
To be honest, easiest option would be for anyone here that needs them (which doesn't seem like there's a huge amount of us that are using TM180x), can just grab a couple online from RS Components:j1sys said:I will be sending out replacement chips to all past purchasers in the USA and Canada and will work with someone in Aussie land to drop a set in the mail to all Aussies at our expense.
I'm pretty sure Ed found that his test 6803 and 2801 lights all worked fine with either chip - the main difference was just for tm180x - it seems to require the ACT to work properly (I think in part due to being 12v)Mike said:So what chip does the 6803 and the 2801 like better then?
