(A) Entering procedure: Except in WRAP mode, while EKM8022 received the following consecutive command. i. F3 C8 ---- set sampling rate 200/sec ii. F3 64 ---- set sampling rate 100/sec iii. F3 50 ---- set sampling rate 80/sec (B) Operating: a. All of the commands in legacy mode still be valid. b. The ID code of read device type command (F2) will changed from "00" to be "03". c. Data report will be four bytes format:

(C) Exiting Microsoft scrolling mode: There are two ways to exit: a. Power off. b. Reset command (FF). Z-axis Input Function : The Z0-Z7 limit value is 7 Z-axis counter accumulates the Z1, Z2 phase changed by movement. This mode includes noise immunity. Z/2 : 2 dot per count. The wheel should stay at Z1=0, Z2=0 or Z1=1, Z2=1 Phase Z/4 : 4 dots per count. the wheel should stay at Z1=0, Z2=0 phase.
