A: AC INPUT - Primary power input for power supply.
B: AC INPUT - Power input here is switched by relay to the (C) ROUTER output.
C: ROUTER - Connect to the green power cable from the machine harness. On-screen spindle controls, as well as M3/M5 g-codes will control this output.
D: USB - Connect to USB connector on PC. Powers the logic supply of the board.
E: PARALLEL PORT - Connect to the primary (built onto the motherboard) DB-25 connector on the PC.
F, G, H, I: MOTOR CONNECTIONS - Connect to each of the labeled motor connections from the machine harness.
J:
K: LIMITS - Connect to the 8-pin limit switch connector from the machine harness.
L: E-STOP - Connect to the 2-pin e-stop connector from the machine harness.
M: AUX - This is a 5V logic level signal that can be connected to a PowerSwitch Tail or other 5V@20mA relay circuit. This signal is controlled by the flood coolant controls in the software (M8/M9).
N: EARTH GND - It is recommended that the machine is grounded to earth. Connect the two black wires from the machine harness to this connection. Additional earth grounding may be necessary when working with certain spindles or certain types of materials that may cause excess EMI or static electricity.
