SOFTWARE CONTROL FUNCTIONS

9.1 Software Interface Description

The Sensor software interface is accomplished across a single hardware communications channel.
This channel is factory selectable to be either RS-422 or RS-232. The channel baud rate is set at
2400k, 9600k. This channel carries command/status data for all three devices; IR Imager, visible
imager and the pan/tilt mechanism.
The RS-232 configuration is as follows:
Baud Rate
Data Bits
Parity
Stop Bits
Flow Control None

9.2 IR Imager

This section describes the structure of the commands of the IR imager on the PTZ-35 MS / PTZ-50
MS. Note that all data values are called out in hexadecimal. The command and response strings of
the IR imager interface are of variable length, ranging from 10 bytes to 32 bytes. The byte
descriptions are as follows:
Byte 1
Byte 2
Byte 3
Byte 4
Byte 5
Byte 6
Byte 7
Byte 8
