RCP 6x64 Led Scrolling Sign

[kellyseye]

Quite often these displays are fitted with EPROMS for the function they are intended (caller display, counter, people-waiting etc) and to 'enable' them for free-running text this EPROM has to be swapped out for the appropriately coded version. If you can get hold of the IR remote control you stand a better chance of getting this working - else resort to taking it apart and finding the serial data pins right at the LED panel.

Scrap it, keep the lightning and roll your own... then sell it without any information

Well I have a IR Remote for a betabrite that will flash the sign when I push the program button. can't I flash another program to the eprom? What does
that require? I was really hoping someone who had sold these at 1 time had the info and drivers I needed, Its a 3 color sign I hate to just scrap it. The eprom is under
a door on the back of the sign. what eprom could a swap it with?

Thanks

Even if you swap the EEPROM, you<ll need to know how it is implemented in.

What I meant by "Scrap it" was just to remove the controller board inside, access the friver and plug your homebrew thing... after all...it's a Microcontroller forum here

I had a similar panel a few years ago and dismantled it for the parts - the tri-colour (red/green) LED matrix displays are very sort after on eBay - by the time I'd stripped it and sold it for the bits I got more than 6 times what I paid for it originally!
