content: Hello.I am about to receive from a deal a Thermal Core FLIR Indigo/Micro A10 "drone" (160x120).I was trying to do my homework and i found this very interesting thread here:https://www.eevblog.com/forum/thermal-imaging/flir-micron-a10-160-x-120-hiding-in-disguise-bought-for-$100-)/And also, this documentation (localised on the page dedicated to the pin-out of the main connector:https://www.manualslib.com/manual/757364/Flir-Thermovision-Micron.html?page=39#manualNevertheless, i am a bit still confused with the wiring of this unit. I would like simply to use it in the "power input -Video output".It is my first core i will have, and i would not like to mess it up with it because of silly connections mistakes.I would be grateful to the community if someone could "light my bulb" by explaining to me the precise wiring and what wires to use in this basic mode.In case i would have missed in the forum an obvious bunch of past posts dealing about this thema, in advance my apologizes for the potential doublon.In advance, thank you for your help.Best regard.Stéphaneps: i attached a photo of my coming unit with some "hypothesis"/guesses concerning the wiring...

content: For power in, video out, you'd need connected:PWR is positive inputPWR RTN is the power connection's groundVIDEO is the analog video output (composite)VIDEO RTN is the ground for the analog video connectionDGND is the ground for the three differential data lines and the RS232 comms.You can see on the next page that there are different connectors that actually have these connections functionally grouped, which may be easy to interface with depending on whether they're exposed or not on your core.

content: Thank you a lot for your input, DajMasta.I read carefully this part of the documentation indeed...Sorry, my English is sometimes inaccurate....More precisely, i fully inderstand the legend and meaning of each pin from the 18 pin-connector.... My problem is in fact the following:- I do not know the correspondance between each of the bunch of wires coming out from the black connector and each of the 18 pins described in the diagram (table A1 from the FLIR document.At least,if i would know the reference pin from the slot of the PCB(where is the pin number 1 ? at which end of said PCB slot ?), i could try to find with a multimeter, by testing pin after pin, what are the respective good wire.But again, i would need to know at least, at which end is the starting pin "1"....I try to put a small drawing for compensating my hesitating English...Again thank you for your advice.Best regards.Stéphane

content: PCB silkscreens often have something, but the connectors themselves usually have an indicator of what pin one is. I'd either look up the connector datasheet to see how it indicates polarity or just wait until it arrives and try to deduce what side it is from the silkscreen.Trying to guess from the external connector is probably not worth it because they can put the pins that connect to external hardware at whatever they want, so if the connector doesn't indicate and the board doesn't indicate, maybe then you can try to deduce wire color from the given pinout and their arrangement at the connector on the board.Not that you should use this is a primary indicator, but if I had to guess from the wires alone, the twisted pairs are differential digital data lines, and the thickest wires in the bunch are power and ground.

content: Ok DajMasta.Your guidance is clear and it makes really sense.Thanks to the elements you gave to me, i will establish a small "algorithm" for "decoding" each wire....Easily, everything related to ground should be already labelled.For instance, i see that pin 2 and 4 are ground for the DC supply.Therefore, starting from the wrong end, when testing with a multimeter should bring me to 17 and 15 corresponding to "Digital output channel clock" and "Digital data output channel", which i guess would not be especially grounded....And adding some additional clues step by step should confirm the "map" of the PCB connectorI will investigate also the connector datasheet.Thank you for the good practices.Best regards.Stéphane

content: The connector and cable looks like mine from the MSA Evolution 5000.Power are the red/black twisted pairs, video out is the blue/black pair.I marked pin 1 on every connector.

content: Cat! Marvelous!(I saw you were involved in the thread created by Fraser concerning this type of Core...)Thank you a lot for these very explicit photos!In combination with the indications given by DajMasta, to be applied for a double checking.I think i can breathe now and wait with serenity my core.Best regards.Stéphane
