My Problem:

I have some older serial numeric keypads that are getting hard to replace. I tried a USB keypad but the distance of the cord wasn't long enough, so I tried using a USB to ethernet and ethernet to USB extension. It works, but has intermittent problems. Sometimes it requires a reboot to get the system to respond.

My Questions:

  1. Where can I get a variety of industrial grade devices?
  2. Are there other alternatives to a USB keypad?
  3. Can anyone give other suggestions to a solution. E.g. I thought of adding an LCD touch screen in place of the Keypad...

Does using a separately powered USB-hub give you any better success with the USB solution? – uSlackr Oct 11 '11 at 17:12
Have you tried a USB extension cable? – CharlieRB Oct 11 '11 at 17:49

Here is "the highest quality serial numeric keypad on the market"

The keys are rated for 50 million cycles, and the company seems to be an industrial product manufacturer.

Believe it or not, Wal-Mart sells these for $50

What's the distance that you need these to be from the PC they are connected to?

You can also consider They also sell USB extensions that use RJ-45: – user 99572 is fine Oct 11 '11 at 21:08
