FW8-STL Operating Manual
April 3rd, 2007
Introduction
The FW8-STL (External Filter Wheel) is an 8-position Color Filter Wheel for use with SBIG and third-
party CCD Cameras. It accepts up to eight 50 mm or 2 inch filters. It interfaces to SBIG STL USB Port
based cameras through the camera’s I2C port, obtaining power and control from the camera. For SBIG
Parallel Port based cameras or for cameras from other manufacturers power is obtained from a separate
12V DC power source and control is through a Serial Port (RS-232).
