(C) Exiting Microsoft scrolling mode:
There are two ways to exit:
(a) Power off.
(b)Reset command (FF).
3. Z-AXIS INPUT FUNTION: The Z0 ~ Z7 limit value is ±7
(A) Photo couples input: Z-axis counter accumulates the Z1, Z2 phase changed by movement. This mode
includes noise immunity.
Z/1: 1 dot per count.
Z/4: 4 dots per count. Counted by Z1=1, Z2=1 phase, the wheel should stay at Z1=0, Z2=0 phase.
(B) Key-switches input: Pressing Z1, Z2 will start to fill the Z-axis counter with the value beginning at one.
Toggling “M” key can increase the value any time by one. The limit value is ±7.
The relationship between the value and the transmission rate as follow:

(C) Voltage-sensing mode: There are 7 voltage levels in Z1, Z2 input. The transmission table is the same as key-
switch mode. The relationship between the value of Z-axis counter and the voltage as follows:
Value

Under VDD = 5V condition
Voltage
1V ↓
1.0V – 1.6V
1.6V – 2.2V
2.2V - 2.8V
2.8V – 3.4V
3.4V – 4.0V
4.0V – 4.6V
4.6V ↑
(D) Mechanical mode: The function is the same as photo couples input mode, except there is no noise immunity.
Z/1: 1 dot per count.
Z/2: 2 dots per count. Counted by Z2 changing phase.
