Looking for keypad + LCD display with RS-232 link.

How many?

I know, but I currently do not have the time, and I need a stopgap solution in the mean time. If I can get a product at a reasonable price. i.e. MUCH less than US$200, I would just stick with the bought out unit. If I can for US$200, I will use them until I have time to build my own. I of course would rather chew glass than build this using a PIC. :)

Thanks, but they have a full qwerty keyboard. I have found many products with full or nearly full keyboards, but are battleing to find something with only 11 upto 20 keys. I can find keyboards alone, but not the display/keyboard combination. It is hard to believe there is no requirement for such a product.

Your best bet is the Mega32 Control Board from Futurlec (~ 45 USD). It has interfaces for RS232 and a character LCD (such as Powertip PC2004) and plenty of extra I/O for any keypad you choose.

I have loads of C code for it.

Several possibilities here:

You could allways just pay someone to write the code for a pic, or whatever, and then put it together yourself.

How about using the cheapest Palm pilot

No "real" keyboard of course.

Anton,

Send me a message offline. We just developed something that should fit the bill perfectly for you and be considerably cheaper than your spec. Send an email to ceiboss at hotmail dot com.
