Installed the fan kit as per instructions on this site.
It seems that the fan control board is a fraction if a millimetre too wide to not collide with the housing. Fixed it by de-soldering the control board and re-applying solder with the control board in an ever-so-slightly higher position to slide into a fin in the chassis.
Upon reassembly, nothing seems to work. When plugged into a high power USB port, the background light in the display turns on for a fraction of a second, and the device manager does not recognize the device.
I'm slightly frustrated, and unsure where things went wrong.
Sorry you're having trouble.
Do you have any way to measure current on the USB port?
Also, are you able to take a photo of the installed fan kit PCB?
I'm sorry for the delay.
You don't allow new users to dump photos.
I butchered an otherwise fine USB cable, googled the wires to connect to, verified with a continuity tester, set a power supply for 5V±0,01V and measured the current.
Checked that I connected the ribbon cable properly.
The Re:Load draws 4,74 mA, and the display is still off.
I desoldered the fan kit, assuming I did something wrong, yet to no avail.
If it's drawing that little current, it's likely that the FTDI IC thinks it shouldn't be enumerating because it's not connected to a valid host. The PWR pin on the connector will be high if that's the case. Pulling it low (say, with a bit of wire or a resistor) will turn the Re:load Pro on.
I've modified your account so you can post photos.
Can you be more specific on what the reload pro expects on the USB port to turn on ?
I have some USB ports where it works perfectly, some where it just doesn't turn on and then even one port where it will start and then periodically reset ever so often (self made power supply with resistor bridge allowing iPhone to recognize high speed charging) ......
Would be good to know what it expects on the datalines (besides good 5V power) to turn on without resetting.
The Re:load Pro relies on the FT230X's charger detection. It enables power if the device is enumerated by a USB host, or if the FTDI detects it's connected to a USB battery charging compliant device.
If you want, you can shot the 'pwr' pin on the expansion header in the Re:load Pro to GND, which will cause it to power up any time it has power. You could also do that by using ft_prog to adjust the CBUS pin settings on the FT230X to always turn it on. I didn't ship them like that because I wanted the Re:load Pro to be USB compliant.
That's useful info !
From the following link : http://www.ba0sh1.com/ft230x-charger-detection-investigation/
I now understand why an Apple ipad charger or equivalent is giving problems ! The chip doesn't detect it as a charger .........
Might be useful to indicate this for your users
So I'll add another USB socket to my power supply with just D+ and D- shorted and all should be OK !
I just finished installing my fan kit, and ran into a slightly different problem: The headers would not fit into the holes in the main PCB (the fit into the fan controller just fine.) Of course I only find this out after they are soldered into the fan controller. Some other headers I had here did fit, but not by much, so I think there are some tolerance issues on the holes in the PCB. Got it installed and it all works, although I also noticed that there is not much physical clearance between the
controller and the case.
Again, sorry for the delay.Work has been ridiculous.
It took me a while to parse your instructions, and as I shorted PWR to GND, it fired right up.
Shorting the data lines on the butchered USB cable did the same thing.
I'm going to work around the fan kit PCB collision issue with some ribbon cable and hot glue. (I have the same problem as royfranz). No biggie.
As of now I consider my issues resolved. Thanks.
Have a nice weekend,
