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