*******************************************************
Command code => 141(8Dh) = EXT_TRANSITION_SPEED_CMD
Parameter #1 = > Get/Set: 30h=get, 31h=set (or 00h=get/01h=set)
Parameter #2 = > 30h=reset to default, 31h=+1 frame, 32h= -1 frame, 33h=set by parameter#4
Parameter #3 = > Speed key No.: 31h~36h: Speed#1~Speed#6
When (para#1=31h and papa#2=33h)
--- Answer ---
Parameter #4 = > Transition duration: 1~90(5Ah) frames
Parameter #1 = > Get/Set: 30h=get, 31h=set (or 00h=get/01h=set)
Parameter #2 = > 30h=reset to default, 31h=+1 frame, 32h= -1 frame, 33h=set by parameter#4
Parameter #3 = > Speed key No.: 31h~36h: Speed#1~Speed#6
Parameter #4 = > Transition duration: 1~90(5Ah) frames
Example: Set the speed#2 to 10 frames.
The control data stream: F0h,5Ah,0Dh,05h,01h,8Dh,01h,33h,32h,0Ah,3ah,35h,FFh
F0h, ID(5Ah) , Length(0Dh), 05h, 01h, Command code(8Dh),para#1(01h),para#2(33h), para#3(32h)
, para#4(0Ah),checksum_L(3ah), checksum_M(35h), FFh
Checksum=F0h+5Ah+0Dh+05h+01h+8Dh+01h+33h+32h+0Ah=5ah
The Answer from SE900 = FCh,5Ah,0Dh,05h,01h,8Dh,01h,33h,32h,0Ah,36h,36h,FFh
