I have an application where I need to use an external numeric keypad to send values to a Click PLC. Finding an ASCII keypad is harder than I expected so I found a USB keyboard to RS232 ASCII interface. My question is they offer the interface in both DCE and DTE versions. Which should I use and/or other sources for an ASCII keypad that would be easier to interface (without spending a couple hundred $ on an antique keyboard/keypad) Thanks for the help! Jeffrey

100% what kewakl posted. Do not waste your time on an ASCII keypad. There's no reason to unless you just looking to make something more difficult than it has to be.

Thanks, guys. I have numerous c-more micros, c-mores, etc. in applications. I don't need/want a touchscreen with a small keypad in this case. For this application, I NEED a tactile numeric keypad.
