Just giving an update - I replaced the L13 inductor and our DAQ board is up and running! I am definitely going to be much more careful about checking the coax cables for shorts from here on out. Thanks again for all of your help  :)

Yay! Thank you so much  :)

Hi Kyrollos and Daniel,

It appears I have also damaged the L13 inductor of my DAQ with a shorted coax cable. We have the DAQ V3_2. Is it possible to replace the inductor ourselves? I tried looking for the part in the BOM but was unable to find it. Thank you for your help!!

Hi Daniel,

The new USB cable solved the issue for our new PCB, but our old PCB still isn't connecting. I'm thinking the possibilities are either that the USB port was damaged due to a really stiff USB cable we were using previously, or the board was damaged by a shorted coax cable. I tested the coax cables for shorts, but this is the only other possibility I can think of. Any tips for how to distinguish if the board was damaged? I am posting a picture of the non functioning board below. Thanks again!

It appears to be due to a physical connection of the USB cable with the DAQ USB connector. We are going to test out some different USB cables.

DAQ Software/Firmware / MSCam Frame Retrieve Error

We are having a problem with our system. All 3 leds on the data acquisition box light up when plugged in and the red CMOS light and LED also light up when the scopes are plugged in, however we get the MSCam frame retrieve error across 3 different scopes and multiple DAQ boards (one of which is brand new). The boards show up as MINISCOPE consistently in the computer "devices" window. We have tried multiple computers (Macbook air running windows 10 via bootcamp and a Dell desktop, both of which have worked previously) multiple USB connectors, two from digikey and two from external hard drives. We have tried disconnecting the scope with the DAQ connected, then reconnecting the DAQ with the scope connected first.

The scopes and DAQ have been working perfectly until today. It also seems like there is a great deal of lag in initiating the scope - when we plug it in there is lag for the computer to recognize it, and in the software once we click "connect" there seems to be a lag in connecting -> led power update -> mscam frame grab error.

Any suggestions are greatly appreciated!

Hi Daniel,

It turned out to be that our LED wasn't soldered to the LED PCB correctly so we think it may have been shorting where the wires connect. After straightening the LED and building up the solder on the wires we are in business! Thanks for all of your help  :)

We have our system set up but are having issues with the excitation LED not powering on.

All LEDs on the DAQ box light up and the red LED on the CMOS sensor light up when connected to the computer. We are also able to obtain an image using the software. However, when we connect the scope the blue excitation LED does not come on and doesn't come on when we change the intensity. The half circles on our CMOS sensor have been soldered together.

We thought it may have been an issue with damage to the LED, but we soldered a new LED onto a new LED PCB with no success. Any insight would be appreciated!
