==Dali D8X3N Thermal Camera Reverse Engineering==
Then download the '''rawviewer.zip''' from [https://archive.org/details/rawviewer_202508 here] (rev3 with histogram, javascript)
unpack the web folder into '''/app''' and '''restart''' your camera.<blockquote>
It should be accessible now trough '''http://<camera ip>/raw.html''' in the browser and click '''Start Stream'''
<br /><blockquote>performance may need improvement.</blockquote>
====to permanently enable Telnet, go to '''/etc/init.d''' and edit '''S90app'''====
======Bad Pixel and Flatframe Maps 0x280000 and 0x4C0000======
There still needs to be work done ''See "Automatic Dead Pixels and Flatmap Correction" below how to create own maps new dead pixel and flatfields but flatmaps using the cameras are still very capable and useable with fully cleared mapssystem menu. To clear the maps, just go to these offsets and fill with values around 0x3F or 0x0 for total length of X Resolution x Y Resolution x 2 bytes (0x96000 for 640x480)''
The breakout board files can be found [https://oshwlab*FPGA JTAG*UART 3.com/gamerpaddy/d8x3c3V with pin compatible FT232 socket*Power 5V over USB-backpack-usb here] but may be still work in progressC*5 Button inputs*Buffered video output and socket for USB Videograbber*Digital 14 bit video out header with hsync vsync and clk.*
added professional pcb adapter

==Viewing the Video Stream==
[[File:Onvif Device Manager ODM.png|thumb|ODM streaming the Thermal view]]
when first connecting it to power and Ethernet, the camera will have 192.168.1.102 as a Static ip.
*<code>Snap=[Yes/No]</code> - Enable snapshot mode
<br />
====Raw Viewer for PC (Python)====
[[File:Dali D8X3N Raw Thermal viewer.png|thumb|Raw Data Viewer in python]]
rev2 with temperature readout https://pastebin.com/u107Q85w
rev3 and onward will only be available directly as a Webpage on the Device (see below).
====Raw Viewer for the internal Webserver (recommended)====
[[File:Dali D8X3N Webviewer.png|thumb|Web Raw Viewer with histogram (rev3)]]
Create the files and the code inside.
'''/app/web/webpages/raw.html''' https://pastebin.com/kaiXwAgD
and
'''/app/web/webpages/cgi-bin/proxy.cgi''' https://pastebin.com/vii1HXcU
then run
chmod +x /app/web/webpages/cgi-bin/proxy.cgi
'''restart''' your camera.
It should be accessible now trough '''http://<camera ip>/raw.html''' in the browser and click Start Stream
'''NOTE''': ''<u>If it does not work</u>'', check the contents of both files. FTP sometimes messes them up.
also run
dos2unix /app/web/webpages/cgi-bin/proxy.cgi
because linux <> windows difficulties that couldnt be resolved in over 30 years.
performance may need improvement.</blockquote>
==Getting Root Terminal Access==
To access the Terminal you need to solder or plug in a UART connection to Connector J7 on the "Glue" board.
This only works if you also patch the Thermal Camera module flash!
vi S90app
in vi, move your cursor to the '''#''' at '''#telnetd''' and press x<blockquote>optional: enable ftp by removing the '''#''' at '''ftpd''' and adjust the path to / </blockquote>now press ''':''' and type '''wq''' and hit '''enter'''. this should be it.
== Hardware Hacking ==
<br />
Thermal cameras require a bad pixel and flat frame map to compensate for manufacturing inconsistencies.
The [https://2477569.playcode.io/ Viewer Page] is written in JS and does not require any special dependencies, it can run as a plain html file offline.

=====Dead pixels:=====
In the secret menu "System", navigate to Debug Area - DeadPixelModel and set the AutoBP (sensitivity for auto bad pixel finding) to 50 or so. Then press C Button
This can take a while.

==Using the Thermal module without Webserver==[[File:Dali D8X3C Breakout boardBreakoutboard d8x3c dali v1.1.png|alt=|thumb|Breakout board for D8X3C ]]
to use it, you need to interface it directly.
To interface, you need to make have a adapter board with a DF12-50DS-0.5V(86) Docking socket.
A open source project can be found here, it includes pin access to:
the pcb layout has been tested and seems to work.

==Sending Serial Commands directly over UART==
Sending Serial commands directly over UART to the core requires some additional bytes.
The packet structure is as follows (Strip spaces, commands are allways uppercase and 3 chars)
<STX> <LENGTH1> <LENGTH2> Command, Value, Checksum <ETX>
Pseudocode to craft a command packet may look like this<syntaxhighlight lang="c">
//cmd is allways 3 byte uppercase chars
//values can be multiple comma seperated like 320,240
function make_packet(cmd, values):
payload = cmd + "," + join(values, ",") + ","
bytes = ascii(payload)
length = len(bytes)
checksum = sum(bytes) mod 256
return [0x02, length&0xFF, length>>8] + bytes + [checksum, 0x03]
</syntaxhighlight>

==Sensor Pinout==
[[File:Dali DLD384 Sensor pinout basic.png|thumb|basic pinout of a DLD384]]
the pinout of the thermal sensor havent been analyzes much.
