I solved now the power supply issues on my Ti45 thermal camera. :D :D
But now I need the content of the "internal SD-card" to boot the system up.
( I got the camera without the SD-card ..... |O )
Can somebody please help here ???
Thanks

I believe I have the files somewhere from when I had to replace a blown tantalum capacitor. Let me have a look. I assume it's for the SD card in the image attached?
-
I have attached what I think are the files I took off that internal SD card. This was back in 2015, so I don't know if this is all of the files. It is from a TiR3 I fixed.
-
Did this work?
-
Hi Chanc3
First of all BIG THANKS for your help. :) :)
I just copied the files on a SD-Drive an tired it on my Hardware.
unfortunately it did not work,.....
Do you possibly know if I should see any "boot activity on the screen" without the SD-Card.
Do I need a WIN-CE image on the SD-Card ???
Would be great if somebody can answer !

In your position I would ask FLUKE support if the SD card is available pre-programmed as a spare part. You could also ask if its presence is required for the camera to boot. FLUKE can be quite helpful if you get the right tech answering your questions.

I tried it at the Fluke support, but it seems, that I didn't get the right tech support, to help me. ... :-//

An issue that you may run into is the fact that FLUKE do not actually make the Thermal Cameras. They bought in the technology and also bought Raytek.
In such cases it can be hard to find the right person within a large organisation who has the required knowledge to help. With 'bought in' technology it is often not possible to obtain internal spare parts. I have a suspicion the Ti45 was a 'bought in' model.

Thanks all so far,
can anyone give me the the original “Fluke part #” of this SD-Card which I need for the TI-45
that I can try to get it via the original FLUKE service ! :-//
THANKS !! Max
-
i have the SD card content and i need part number of U7!
-
this file is true!
-
Good work Ali,
Hopefully Medmax can return the favour with the U7 identity information you need :-+
Fraser

Hi Ali,
did a short look yesterday into the electronic to identify the U7.
I found there the Marking AAY on the chip.
Then I found the following types with marking AAY in my SMD Marking list.
I hope this helps !!
( .... had no futher time to check the SD-content, will give you feedback on that later !! )

very very thank you! :-+ :-+

Hi Ali
Here the requested PIC of the U7 orientation !
-
thank you MedMax
:-+ :-+ :-+

Dear MedMax. Did you repaired your camera? Does it working now? Thanks
-
Dear mai pham,
yes,
after several deep investigations in the electronic, i got it repaired !

I saw a faulty camera like yours on eBay a while back and thought you had given up on it :) It was a Ti55 model though and sadly missing its lens :(

Glad you managed to get it repaired. Did the repair sheet say what they did to it ? Enjoy your camera :)

I have the opportunity to get a Fluke TiR4FT camera "like new" for pennies, but I understand it is limited to -4°F to 212°F (-20 to 100 °Celsius).
I was planning to use it in an industrial environment (electrical cabinets, motors, ball bearings etc.), can I use it for temperatures above 212°F?
I just want to get an estimate reading, I have no problem with it not being CALIBRATED outside of that range, but can it discern temperatures
outside that range?
Thank you!

Razvan_N,
I own a few Fluke thermal imaging cameras. Sadly the specified temperature boundaries are hard limits and temperatures above 100C will just show as the highest colour in the particular colour pallet that you are using. Thermal imaging cameras will normally have a “high sensitivity” range that extends from something like -20C to +120C. In order to measure higher than +120C (in this example) a lower sensitivity range is used. The lower sensitivity range uses different microbolometer bias settings and calibration tables to that of the high sensitivity range. The low sensitivity range is often able to cover 0C to 650C maximum but top ends are commonly less than this in budget cameras. +450C or +550C is not uncommon.
You cannot enable a low sensitivity range on a Fluke thermal imaging camera that has only the high sensitivity range, unless you hack it and create any missing calibration tables. Not something I can assist with as the fluke cameras have not been reverse engineered in the same way that FLIR cameras have.
There are tricks to lower a cameras sensitivity to enable it to image targets of higher temperature than would normally be possible, but that is very much a case of trial and error using different plastic films, thin glass, silicon windows or partially mirrored CO2 10.6um laser windows. Measurement accuracy of any sort is pretty much lost using this method however (you would need to know the attenuators transmission loss across the LWIR band to calculate the measurement correction required)
Hope this helps

Do you think this camera would be useful for my scope? Industrial machines, overheating bearings, motors, that kind of stuff?
Mostly in the ropeway industry. I believe I would be able to see a slightly warm sheave bearing on a tower (from the maintenance
platform near the sheave assembly), but what about overheating motors and so on?
Do you have experience with electrical things that would function normally above 100 deg Celsius? Because I won't be able to tell
if they work properly or are overheated.
-
Sorry, that is not my Industry so I cannot advise.

'For pennies' worth a punt.
It is a fairly narrow field (23° horizontal) 320x240 camera:
https://www.fluke.com/en-us/product/thermal-cameras/tir4ft. (https://www.fluke.com/en-us/product/thermal-cameras/tir4ft.)
You need to do the maths on whether the objects you want to look at will fill a couple of pixels from the distance you are at.
If so, then you would likely notice 'the left one is hotter than the right one', but I would not rely on measurements in absolute terms. You are looking at slightly shiny metals outdoors so emissivity comes in significantly.
There are electrical things that work over 100°C.... cookers and kettles :-DD
(sorry could not resit that one ;D )

Hello, I also encountered the same problem with my Fluke TI55, and also tried to replace the system board card to judge the system card protection. There is nothing wrong with the SD card :-//
-
Does TiR4 have an internal battery? Something like CR2032 to keep the clock running?
-
According to FLUKE, the TIR4 uses a battery backed real time clock so you are dealing with a battery, rather than a super-capacitor, but exactly what type and mounting is not known to me.
Some RTC backup batteries are Primary cells (normally a Lithium cell) but others are Secondary cells (normally Ni-Mh or rechargeable Lithium) charged by the host whilst in use. Be careful not to replace a rechargeable Lithium cell with a non rechargeable type. Check the cell type using the data sheet.

Hi
Can anybody provide the files on the Ti55 internal SD card, please?
I tried the ones from Ti45 posted here but it is stuck at the splash screen.
all power supplies and oscillators (there are many!) are good and I see activity on memory pins...
edit: the LogicPD CPU card and the whole digital board of the camera are exactly identical to
the pictures from Ti45 and TiR3 that were posted here on eevblog

Do you have the original SD Card or is that missing ?
A “Halt” at boot suggests the camera is failing its self test or file integrity check. If the SD card files contain a CRC or other feature that locks it to the particular camera hardware, you will likely have a problem getting it to boot with someone else’s SD Card file set. Some investigation of the firmware file set may be needed to discover whether this is your problem.
Fraser

You could gain greater insight into what is occurring at camera boot by monitoring the boot log that comes out of the Serial engineering port on the camera. You should see the progress of the boot and where it halts due to a problem.
Make sure that the SD Card is suitable for the role and not a higher capacity than the camera can handle or containing the wrong format.

I do have the SD card but it is not an original SD card. It must be a 2GB blue card made by Delkin but it is a 512MB SD by Sandisk. Therefore I think the card was prepared by previous owner and he didnt succeed. When I look at the contents of Ti45 and TiR3 posted here there are 4 files. One is the splash screen. One is the RBF file which is the Altera FPGA program on the main board (Ti45 and TiR3 are identical and also identical to what I have) and then there are two files DOAS.HEX and DOAS.KEY. I think these files make up the contents of either the MPS430F147 microcontroller or the TMS320VC5510A DSP processor on the main board.
Now I do have a DOAS.HEX file but I do not have DOAS.KEY file. My DOAS.HEX file is also different than the Ti45 and TiR3 posted by other users.
SO I think I might be missing that DOAS.KEY file. I am pretty sure the FPGA file must be the same. The SD card only contains these 4 files (I only have 3)
All the firmware including the bootloader and wince etc... are all stored in the FLASH memories residing on the LogicPD CPU card.
So if anyone has the contents of the Ti55 SD card, can you please contact me?
It might be so that my SD card does indeed have all the files for this model and the non-boot problem is somewhere else but at this point
I need to make sure it is not the SD card content

yes I tried in vain to find any sort of serial debug activity on the 3 pin headers on the board but all those pins are silent. I am 100% the debug info flows if either one pin is pulled low or perhaps a certain character is typed into the RX line (wherever that is) to enter the bootloader
I had a similar experience with another instrument using a LogicPD CPU board that only when you typed in a certain letter quickly at the start then it would stop the boot and take you to the bootloader otherwise there was no activity. However the good thing was that I was able to find the datasheet of that LogicPD CPU boad and trace its UART pins to a header on the board. Here in this camera unfortunately the LogicPD board is very very old and there is no mention of it anywhere let alone its datasheet...so I cannot know where the serial port might be
However, I have confirmed that there is activity going on all SDRAM memories so it is not dead or in reset...so something is happening but ....
EDIT: by the way the main board and the LogicPD CPU card in this unit looks identical to what was posted earlier in this thread from a Ti45 (or was it TiR3?)
anyways, they look exactly the same with same numbers on the parts.

Answering my own question from a while ago.
TiR4 uses a primary cell to retain time and date: CR2477, a thicker version of the typical coin cell.
