G3 and G4 CCD Camera Driver for SIPS
SIPS is designed to work with any CCD camera, providing the driver for the
particular camera is installed. The driver for G3 CCD camera is include into
the basic SIPS package and is not necessary to install it separately.
All Gx cameras use common driver 'gxusb.dll' when connected directly to
the host computer or 'gxeth.dll' when connected trough the Gx Camera
Ethernet Adapter.
Common drivers for all Gx cameras were introduced in SIPS version 2.3,
previous SIPS versions used different drivers for G0/G1 and for G2/G3/G4
cameras. G3 and G4 cameras used the 'g3ccd.dll' driver, but it was replaced
with the 'gxusb.dll' common driver.
Every CCD camera driver for SIPS (including the G3 and G4 CCD drivers)
is required to provide information about available filters (if the particular
camera has the integrated filter wheel, of course). But the user can order
camera with various filters, or he or she can change individual filters or the
whole filter wheel etc. There is no way how to determine the actual filters in
the filter wheel automatically. This is why the G3 and G4 CCD camera
driver for SIPS reads the 'gxusb.ini' file to determine actual configuration of
filters, which will be then reported to SIPS.
Let us note that G3 and G4 CCD cameras are software compatible so they
use the same driver 'gxusb.dll' as well as driver initialization file.
The 'gusb.ini' file is placed in the same directory where the camera driver
and the SIPS itself is installed. This file is ordinary text file following the
.INI files conventions. Here is the example of the 'gxusb.ini':
[filters]
Luminance, Gray
Red, LRed
Green, LGreen
Blue, LBlue
Clear, 0
