6.1 Troubleshooting/FAQ
Installation and connection
Installation of the Thorlabs camera software fails.
You need administrator privileges to install the software. Operating the cameras, however, does
not require administrator privileges.
The camera is connected to the PC, but cannot be opened in Thorcam
Check the LED on the camera:
LED is red: Camera detection failed. Check whether the TSI driver software has been installed.
Disconnect and reconnect the camera to the USB cable. The camera should then be correctly
recognized.
If the camera is still not listed in the uc480 Camera Manager, open the Windows Device
Manager to check whether the camera has been correctly recognized. If recognition was
successful, you will find an entry in the format “uc480......cameras” under “Universal Serial Bus
Controllers.” A question mark or exclamation mark before the entry indicates that camera was not
correctly recognized. You can remove the entry using the shortcut menu (right-click). Disconnect
and reconnect the camera. The Found New Hardware Wizard will detect it as a new device and
install the appropriate drivers. The camera should then be correctly recognized.
LED is green: The camera is fully operational. Check whether the camera has been opened in a
different application.
LED is off: No power supply to the camera. Check the cable, the connectors and, if applicable,
the power supply to the hubs. In case of a DCU22xX or DC1240X camera, check whether any
pins of the micro D-sub connector have been bent.
LED flashes: A fault has occurred in the camera hardware. Please contact the Thorlabs.
USB DCx camera operation
The camera can be opened in the software, but captures images sporadically or not at all.
Check for dropped frames in the settings window of the ThorCam software. If significant
percentage of dropped frames are reported, the camera speed settings are too high for the system
you are using. Check the following:
Use only USB 2.0 (USB 3 in case of DCC3240x) certified cables and hubs.
Do not use any passive extension cables.
Do not connect the camera to the USB ports on the front of the PC, but to the ones directly on the
main board. You will find those USB ports at the back of the PC.
In addition, check the following camera settings in the software:
