Thanks for checking your stock.? I will let Lee contact you off line, since he's the one who stocks and kits the kits.
I believe I can say "kits the kits"... both a verb and noun right?? LIke who's gonna kid a kid?
If you need any help or advice on RS-485, please don't hesitate to ask me.? I'm practically an expert on that subject!
Isolating the RS-485 is definitely a good plan.? I hope you are using 3 wires for the bus (A, B and Ground).
Cheers,
Josh

Actually, I'm already doing a re-spin of the product, to make it more environmentally robust, use a better A-D converter (the one I'm using now has caused many problems), and fully isolate an RS-485 interface.? I'll still need to produce a limited number of my existing design, in order to support spares for existing installations, but in the future I'll "mass"-produce only the newer version.
So, although it wasn't my original intention, I'll see what I can do about changing to a more off-the-shelf display.? A quick perusal of DigiKey doesn't turn up *any* 7- or 8-digit displays, and the 4-digit ones start at about twice the size (and twice the price, and I'd need two), but I'll keep looking.
In the meantime, if a smaller quantity would help out, I'm sure I can spare a few (or a few dozen, probably - I'll check my stock the next time i get to my warehouse). Contact me off-list and we can work out the details. ~~
