Looking for LED Ticker Sign with Serial Input

Greetings,

Could anyone suggest a source for inexpensive LED "Ticker" signs with serial inputs?

I need a few do do some basic message display from a control system.

Thanks!

    Check out the BetaBrite

    Hi TurnipTruck,

    I?ve got just the ticket for you. It?s called the BetaBrite and you can pick them up at most Sam?s Clubs for about $160. It comes with an IR remote control, some messaging software, and a 25 ft. serial cable but the real power comes from the ability to control it yourself via the Alpha Sign Communications Protocol.

    The 123 page protocol document can be daunting at first glance and it took me several reads to get the hang of it but it?s not as bad as it looks. The feature set is incredible. There are quite a few special effects and animations built into the protocol and you can program your own custom animations also.

    One thing to note is that the sign will keep accurate time once the time is set unless it loses power, however, the sign will not change the date automatically. If you want to use the date function you?ll have to set the date each day.

    Here is a link to the BetaBrite and a link to the protocol.

    I bought my BetaBrite a couple of years ago and it?s one of the best $160 toys I?ve ever invested in. If you do decide to pick one of these puppies up, let me know and I?d be happy to post a few lines of code that will get you up and running.

    Hope this helps,
    Joe

    I will go buy one this afternoon. Any jump start that you could give on the protocol would be appreciated.

    Hi TurnipTruck.

    As promised, here is the code with a few examples on how to manipulate the BetaBrite. Just plug in the supplied cable directly into port 1 of an NI series serial port, no crossover or adapter is needed.

    This only scratches the surface but hopefully this will help you hit the ground running. The BetaBrite can hold multiple text files (messages) and you can schedule when you want them to run and what sequence to run in along with an assortment of other options.

    I use mine to display the current time and temp, daily trivia, today?s events (Jimmy is 16 today. Happy Birthday!), upcoming events (It?s a full moon next Monday. Beware!), stock quotes, and caller ID. I?m a geek, I know. What can I say? :)

    What type of application are you looking at for the ticker?
