9.4 Pan/Tilt Mechanism

This section describes the structure of the commands for the Pan/Tilt on the PTZ-35 MS / PTZ-50
MS Sensor. Note that all data values are called out in hexadecimal. The command and response
strings of the Pan / Tilt Mechanism interface are of variable length, ranging from 5 to 32 bytes. The
format for these command / response strings differs from the IR Imager in that the number of data
bytes is not included in the string. Rather the word is terminated by an "End-Of-Word" byte. The
byte descriptions are as follows:
Byte 1
Byte 2
Byte 3
Byte 4
