I have been looking for simple low cost Keypads w/RS-232 output. What are some
good manufacturers? Looking on the Web I keep ending up at Amazon or Ebay, but I
want to call up (someone who knows the product) before buying. I need to have at
least 3 keys but more, say digits 0-9, would not hurt. Needs to have 9 pin
serial output. (Or 24 but pref. 9. Or I could use an adapter it it came with a
USB connector.)
Use is for part of a Statistical Process Control system that is already set up
w/RS-232. Presently this is set up for digital measuring instruments using the
smart switch 232BBS4 from B&B Electronics (they don't have anything like I
describe above, I asked.). In any case not all measurements are suited for
micrometers or calipers, in some cases gage pins are used. The keypad would be a
convenient way to capture the results. Machine operators would press one key for
a good component, another for undersize, and another for oversize.
I would greatly appreciate any leads.
Thank You,
