SightLine Applications Command and Control

Summary

This document describes the packet-based messaging command and control protocol used by the

SightLine Applications video embedded stabilization and tracking systems.

IMPORTANT NOTIFICATON!

Individual “Getter” commands have been replaced with a single generic getter command Get

Parameters Function (0x28) which takes as an input the corresponding “Setter” command type id.

For Example:

Becomes...

Get Version Number GetParameter( GetVersionNumber )

51,AC,02,00,5E 51,AC,03,28,00,<KK>

Get Ethernet Video Parameters GetParameters( SetEthernetVideoParameters )

51,AC,02,1b,e3 51,AC,03,1a,<KK>

The objective in making this change is to reduce the number of new command types required in the

future. Currently, when a new feature is implemented, three new commands are implemented: a setter,

getter, and a results reply. With 2.17 and future releases, only a new setter and result reply will be

needed. Most of the Getter function did not require any additional parameters, so a single generic

getter has been implemented, which takes the Setter command ID as its parameter.

Sample Code

SightLine provides sample C/C++ code for writing applications that implement our protocol. This is

primarily seen in slfip.h and slfip.cpp. This code can be used as a starting point for writing your own

application and is also useful for conforming to any changes to the protocol that may take place over

time. Sample code can be downloaded from our web site (http://sightlineapplications.com).
