# Special command

@ Hexadecimal character

% Decimal character

^ Character

, Break character

; End of current packet

& Special operation

2. Special command (Followed by #)

A Address assigned by PTZ configuration

X Acceleration rate selected by user

Sx 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 &)

Sx Delay about ( ([acceleration rate] + 1) * (100 * x) ) ms

x 0 ~ 4

4. Exceptions

Normal character following Escape Sequence, must use break character for identify end of sequence

Some protocols are not to be made command script with above method. It is bec

ause they have another

method of checksum calculation. If your protocol does not use above checksum calculation method, please

inquire Philips through its Internet homepage. In the case, it is necessary to send the protocol together.
