Sorry about your motor, Logan.
I believe they removed the front cover to fit the iris control motor and to mount their own overlay camera. I think they should have implemented this without having to butcher the 300A cover
I found an S300A core in my Vision 3. Would anyone know why the colors of my orange and black wires are "reversed" on my S300A core in my Vision 3? Take a real close look at my pictures. I haven't tested the polarity of the two wires with a volt meter yet, but I believe ISI may have switched the wiring color around by accident? Does anyone else have this 7 Pin wiring layout in their ISI Vision 3 S300A core?
Compare my 7 pin wiring with Frasher's 300A core and the wiring diagram posted here:
https://www.eevblog.com/forum/projects/thermal-camera-raytheon-l3-spi-300d-information/msg930673/#msg930673 and you may notice my orange and black wires are switched.
Also, from the ISI Vision 3 operator's manual, Gain changes the output for both the internal LCD display and Video out (I know brightness only changes the internal LCD brightness, but not for video out). Is the gain knob/pot changing the resistance of wires directly connected to the S300A core? If so, which wires of the 7 pins is the gain pot connected to?
Also, would anyone know which wires enable reverse image polarity switching (Black Hot / White Cold) in the S300A core? According to the Operator's manual for the ISI Surveyor, it has a black top button option to enable reverse image polarity to make Black Hot (if this feature is installed). Would anyone know where the reverse image polarity switch wires connect to inside the ISI Board or S300A Core?
Thanks for your help.
Also, this information is not found in the Vision 3 manual. If it matters to you, this is how you change Temperature units from Celsius to Fahrenheit:
Changing Temperature Display for ISI Vision 3
You must use the video out cable as these steps only appear through video out only.
1.) Connect the video output jack on the camera to a video monitor the display that you will be looking at when making the following changes.
2.) Apply power to camera This can be accomplished by laying the camera on it's back and placing battery on the contacts.
3.) Press and hold both and SW-1 and SW-2 until "Select Crosshair" appears in the upper left comer of the display.
4.) press SW-1 two times. "Select Temp Scale" should now be displayed in the upper left corner. Then press SW-2 one time to select the temperature scale. Press SW-1 to toggle between Fahrenheit and Celsius.
After the change has been made, Wait a few seconds. Do not turn the camera off until the temp scale display disappears.
