Control board connects to an 8 pin RJ45 connector. Its pinout is as follows:
1 - +5V
2 - BUTTON CLOCK 1
3 - BUTTON DATA 1
4 - BUTTON CLOCK 2
5 - BUTTON DATA 2
6 - LED CLOCK
7 - LED DATA
8 - GND
LEDs
LEDs are on a Serial In, Parallel Out shift register. They are connected as follows:
A - MOTOR ON
B - SENSOR (used for external probe sensor?)
C - TEACHING MODE (?)
D - OVER (?)
F - MANUAL (controls active)
G - PAUSE (Program Paused)
BUTTON 1
This has 3 Parallel In, Serial Out shift registers attached. It is only used in Manual Mode:
IC4
X, Y and Z jog handles - Think these are quadrature encoders, being converted to STEP / DIR by MSM5210 chips
IC1
write
run
feed rate
motor toggle
reset
sensor buttons
IC2
Enter
