Hi All

looking to pick someones brain, I purchased a 6x64 led sign recently made by Rainbow Computer Periphials model RH-612RSB. have no information on this and have searched the internet far and wide for help with no luck. All I can find is a link to there web site for a catalog and there tech support team will not give me any information on this at all.
Apparently this unit takes a special driver to read and write to it. I can get software to communicate with it, it sees the sign but will not write to it. It has the RJ12 Connector in the back for serial interface and a remote led on front but to this point can not get any information on the cable, driver, or software to program it. Any information you can give me on this.?

Thanks
Tom
