True Technology Custom Wheel

For this driver, select TrueTech on the Setup tab.

True Technology Custom Wheels come in two versions.

  1. The normal version uses a serial port interface. This driver is intended for operating a serial port True Technology wheel only.

  2. The other version is designed for SBIG camera compatibility; it connects directly to the SBIG camera and emulates an SBIG CFW8. You must use the SBIG Universal filter wheel driver with this wheel.

Select TrueTech to use the normal serial port version of the True Technology Custom Wheel. To configure this driver for a serial port wheel, select the correct COM 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.
