The BBV Star Card command string uses

8 hexadecimal bytes; that is, each data byte is in

hexadecimal format. For example, Hex 06 and 12

represents decimal numbers 06 and 22

respectively.

 Byte 1 (BBV STX) – is always 0xB0

 Byte 2 (Camera Address) - logical address of the

camera being controlled (Address 1 is 01)

 Byte 3 & 4 (Command 1 & 2) – see Table 4

 Byte 5 (Data 1) – pan speed, range from 00 (stop) to

0x40 (maximum speed)

 Byte 6 (Data 2) – tilt speed, range from 00 (stop) to

0x3F (maximum speed)

 Byte 7 (BBV ETX) – is always 0xBF

 Byte 8 (Checksum) – sum of bytes (excluding the

synchronization byte), then mod 100 (Decimal code:

256)
