Desk-top Tutor Keyboard
Posted: Sat 01 Apr , 2017 20:37 pm
Hi
I'm wanting to use one of the (physical) milling tutor keyboards with LinuxCNC...
First question, what is the pinout of the serial port/DB25? Does it emulate a keyboard etc or some other type of serial device etc? From what I understand the pinout is straight, and then a regular DB25-DB9 adaptor can be used.
Second, depending on the first, how does it interface/communicate?
Third, are there any wiring diagrams or circuit diagrams?
Worst case I'll just hack the PCB and use a keypad matrix IO board, but best case all the electronics are there and it's just writing some code for the Linux machine to read the inputs via serial...
Thanks!
