For this driver, select SBIG Parallel on the Setup tab.
Important note: If the filter wheel is connected via an SBIG camera, you must select SBIG Universal, not SBIG Parallel.
Using this driver requires special wiring. Please see Notes on Direct Parallel Port Connection for information on wiring connections.
The SBIG Universal filter wheel driver allows direct control of SBIG CFW-8 compatible filter wheels from the PC’s parallel port. This is useful when running these filter wheels in conjunction with non-SBIG cameras.
This driver will run SBIG CFW-8, Optec MaxFilter, Homeyer, and True Technology Custom Wheels with the SBIG compatibility option (use the TrueTech driver for serial interface wheels).
Select the Parallel Port address in Port. In most cases, if a parallel port camera is used, this must be a different parallel port.
The user can assign names for each of the color filter slots, under Filter Name. If your filter wheel has fewer slots than allowed for by this driver, simply leave the Filter Name in the extra slots blank; they will not appear in the drop-list filter selectors. If the filters vary in thickness, a Focus Offset can be entered for each filter. This causes the focus position to be offset appropriately every time an exposure is taken with a new filter position. If this feature is used, absolute positioning focusers are strongly recommended to ensure repeatability.
