Control Board Interface

[thinkl33t]

Connector

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
• Home
• P2
• P1
• Z0
• Z1

  BUTTON 2

This is a single Parallel In, Serial Out shift register. It has 8 buttons connected:

• X+
• X-
• Y+
