20 Stepping Motor Phase Control
There is 8 output control pins to control stepping motor.mtr_ph0~7 for bi-polar and mtr_ph0~3 for uni-polar.
A. bi-polar:
a. Support 2916 motor driver timing and 2916 compatible driver IC, such as L6219.
Include full, half and quarter step control.
b. Support 3955 motor driver timing.
Include full, half, quarter and eighth step control.
c. Support LB1939,LB1940 motor driver timing.
Include full and half step control.
B. uni-polar:
a. Support 2003 motor driver timing and 2003 compatible driver IC.
b. Include full step two phases on, full step single phase on and half step.
c. PWM control, include frequency and duty control.

21 Watch-Dog Protection
This function can automatically reset the system to initial state, whenever the system is held (no access signal)
beyond the time limit. Be able to enable or disable this function by S/W.
This function can protect motor power, lamp power and ASIC system.
Calculation formula: (30sec.) * (times setting) * (setting no.).
The range of setting no. is 1~15; the range of times setting is 0~1.
22 Lamp Timeout Control
This circuitry can automatically reset the lamp power, whenever the system is setting. Be able to enable or
disable this function by S/W.
Calculation formula: (60sec.) x (times setting) x (setting no.).
The range of setting no. is 1~7;the range of times setting is 0~3.
23 Lamp Power Control
These are two power control ports for lamp. One is for Flatbed and the other is for XPA (Transparency or film).
The resolution of it’s PWM type is 8 bits. Duty range is 1/256~256/256.
Note: carrier frequency is (system clock)/256.
24 Sensor Input
The system support home sensor input port.
