2. Special command (Followed by #)
A Address assigned by pan/tilt/zoom configuration
X Acceleration rate selected by user
S x Checksum calculation method
x = 0 Sum of entire frame, size = 1byte
x = 1 Sum of entire frame, size = 2byte
x = 2 Sum of entire frame except first byte (sync), size = 1byte
x = 3 Sum of entire frame except first byte (STX) and last byte (ETX), size = 1byte
x = 4 Sum and one's complement of entire frame except first byte (STX) and last byte (ETX),
size = 1byte
x = 5 XOR sum of entire frame, size = 1byte
x = 6 XOR sum of entire frame, size = 2byte
x = 7 XOR sum of entire frame except first byte (sync), size = 1byte
x = 8 XOR sum of entire frame except first byte (STX) and last byte (ETX), size = 1byte
x = 9 XOR sum and one's complement of entire frame except first byte (STX) and last byte (ETX),
size = 1byte
3. Special Operation (Followed by &)
S x Delay about ( ([ acceleration rate ] + 1) * (100 * x ) ) ms
x 0 ~ 4
4. Exceptions
Normal character following Escape Sequence, must use break character for identifying the end of sequence
* Some protocols are not to be made command script with above method. It is because they use another
