Byte4	(ID low byte)
Byte5	(data1)
Byte6	(Keyboard-ID)
Byte7	(checksum)

Byte4	(ID low byte)
Byte5	(data1)
Byte6	(Keyboard-ID)
Byte7	(data2)
Byte8	(checksum)

1-2. checksum calculation

1.Address = IDH*32 + IDL

2.Movement Speed: 01-EF ==> begin speed value (01:Slow, EF:Fast)

00 ==> stop

3.checksum ==> B7=(B1+B2+B3+B4+B5+B6)&0x7f
