I'm also on the hunt for the Flir PathfindIR commands
This is all I've been able to gather;
The Full Feature PathFindIR camera is provided for OEMs and installers who want to utilize custom features for their applications. The additional features available on the Full Feature PathFindIR camera are selected and set via a LIN (local interconnect network) communications channel. The white wire in the standard PathFindIR System Cable (308-0159-00) provides the means to send the LIN commands to the PathFindIR camera.
The additional custom features provided by the Full Feature PathFindIR camera include the following:
• Selectable color palettes—white hot, black hot, sepia, and rainbow
• Selectable automatic gain control (AGC)—four AGC settings can be selected
• Additional signal outputs for 8-bit digital video data, clock signal, and sync signal requires OEM cable 308-0152-00.
• 2× Zoom—The central part of the image is magnified twice its normal size.
• LIN command to restore factory defaults
If you have purchased the Full Feature PathFindIR camera and need information on these functions, contact your FLIR representative and request the Electrical Interface Control Document (ICD) that describes the connector interface and the proper formatting of the commands controlling these additional functions. A non-disclosure agreement (NDA) is required in order for FLIR to provide this document.
