Has ethernet magnetics so clearly a hardwired ethernet port on the 17 pin docking connector to try poking at.
Main FPGA is Spartan 6SLX45
Main CPU is TI AM335Z Sitara,
ADCs are AD9240A 14 bit, 10MSPS

Also what I thought were glass pet type RFID tags, but I think shock sensors, visible through slots in the rear panel.
I suspect red is bad..

A new tear down video? Kapton tape!

They are definitely shock indicators.  All 4 red on one, 2 of 4 in the other.

Just put some charge in the battery, and "Power" and "busy" light for about 10 secs (e.g. small linux boot time), then busy goes out.
I would expect that if it was not in a state to start an x-ray, there would be some clear visible indication.
Thinking more about it - you never want to x-ray someone more than necessary, so I can't see any reason why it would not always take and store an image if x-rays are detected - you wouldn't want to have to re-expose the patient if teh operator forgot to set up the plate.
Too tired to play ATM, and probably too busy for the next few days.

What was disappointing was the lack of an obvious seperate x-ray sensor that coule be used to fake triggering, tough I wouldn't be surprised if one of thise buttons does it for testing. I've not had the PCBs out yet - could be a photodiode on the underside.

The last time I saw those Shockguards was on removable disk platters.  :D

Edit: Oops, it was 'ShockWatch', not Shockguard. http://shockwatch.com/products/impact-and-tilt/impact-indicators.

@Mike,

Damn, with those shock detectors indicating red I suppose the warranty on the imaging array is void  :)

But seriously, these plates endure quite a rough life so I am surprised that there are shock sensors needed. The plate should be adequately buffered to protect it. Sounds like a manufacturer keen to have a reason to refuse warranty service ! IIRC the smaller plates cost £10K and the larger ones, a lot more. Imagine breaking one that you had bought with your own hard earned money (people like VET's also use them)

Many OEMs of these plates sell the end user a support contract at great annual cost. I can now see why the end users have to cough up that money as these plates are a serious investment and you do not want the OEM declining service due to 'abuse' by your staff.

I hope these plates give you some enjoyment Mike. They were way too large for my needs and hacking them to operate is beyond my skill set. It would be great if you could source the PC software for the Canon plates, or even an engineering test software. Worth contacting Canon ? From what I understand, the PC just connects to the plate via Wi-Fi and whenever an X-Ray is taken, it parcels the image up and sends it automatically. If another download of the data is needed it may be requested.

It may well be a FIFO system where a new exposure pushes the old one out of the memory ?

By the way, I am impressed with the image coming out of the Fire FLIR camera. Love it. It has gone to a good home with me :)
Thank you for your kindness and generosity today.

All the Best

Fraser

Gumbysauce:
Any one know what the imaging array is made with? I feel like I read somewhere that some are being built with organic semiconductors.
