Camera LED state indicator
There is a two-color LED on the camera body, close to the USB connector. 
The LED is functional only upon camera startup not to influence 
observations.
The LED starts blinking orange when the camera starts to initialize filter 
wheel. Orange blinks are not always the same – they depend on the filter 
position when the camera is powered up.
If the case the camera control unit cannot find the filter wheel origin, the 
camera notifies the user by 2 s long red flash immediately after filter 
initialization failed (orange blinking terminates). Please note the while filter 
wheel initialization is skipped by the firmware when the camera is supplied 
without the filter wheel. So if you notice orange blinks followed by 2 s red 
blink, the filter wheel failed to initialize. Although the camera continues 
operation like the model without filter wheel, it is not recommended to start 
work with such camera – it is not clear which filter is behind the CCD or the 
wheel can be in the inter-filter position. Return the camera to manufacturer 
for maintenance in such case.
Camera firmware finishes initialization by signaling the USB speed, on 
which it is currently operating.
● USB 2.0 High Speed (480 Mbps) is signalized by 4 short green 
blinks.
● USB 1.1 Full Speed (12 Mbps) is signalized by 4 short red blinks.
Working with Multiple Cameras
It is possible to connect multiple CCD cameras to single computer, be it 
directly to USB ports available on the computer I/O panel or through the 
USB hub. The operating system assigns unique name to every connected 
USB device. The name is rather complex string derived from the device 
driver GUID, USB hub identifiers, USB port number on the particular hub 
etc. Simply put, these identifiers are intended for distinguishing USB 
devices within operating system, not to be used by computer users.
