Not exactly sure where to put this, so throwing it in here. I have a scrolling LED sign - it's either an Adaptive or Alpha brand (all the same). Model 320c. Some of these came in different flavors - specific to the application. These signs have an RS323 interface.
I have some of their other signs, models 4120c. With these, a couple of them had different ROM chips then the others, and I couldn't communicate with them So I copied the ROM from one, and burned another. Then they worked fine.
According to this site, http://alpha-american.com/epromlist.html
I can't communicate via RS232 with this sign. The current firmware is 1043-5001J. The letter changes for each new version. However, my version is 1043-5009. That's why I suspect the firmware isn't stock, and maybe isn't setup for the RS232 that I'm using.
So, I'm trying to find a more stock firmware. It doesn't even need to be the latest, but really just a stock version. I CAN buy a new replacement from Alpha for $120. I can buy a whole sign now for $300.
Any chance any one has this model of sign ?
