Appendix C: Troubleshooting 

If you experience problems with the STC camera operations, check the 
following areas: 

Check the power: 

 

Ensure that your camera’s power cabling is undamaged and securely 

attached. 

 

If you are using a portable power supply such as a 12V battery, check 

the voltage to ensure that it is operating at a proper level. 

 

Ensure that the camera is receiving power. The STC-428-OEM camera 
employs thermoelectric cooling and a fan to remove heat. When your 
camera is powered up, you should hear the fan operating. 

Check the USB interface: 

Follow these recommendations to ensure good USB connectivity: 

 

Use only good quality USB cables. 

 

Ensure that the USB cable is undamaged and securely attached. 

 

Avoid using a USB hub if possible.  If you do need a hub, try to avoid 
putting two cameras on the same hub. 

 

If you are operating in outdoor ambient temperatures, be aware that 
commercial-quality hubs often do not work well in freezing 

temperatures. You should use an industrial-quality USB hub in such 
conditions. 

 

Avoid using front panel USB ports on desktop computers.  They have 
internal wiring that will degrade USB signal quality. 

 

Diffraction Limited suggests tie wrapping the USB cable and power 
cable together near the camera in order to minimize risk of the USB 
connector coming loose or being pulling out. 

Check the firmware and SBIG drivers: 

Use the 

DL Config

 utility program to ensure th

e camera’s firmware is up to date

 

and that the latest drivers are installed. Refer to 

Appendix B-3  Updating the 

camera drivers and firmware.
