Error Codes

Error codes are reported by the device firmware. For serial devices the come as ER=x and for HID as a number. These can be used for trouble shooting. Most Optec Software will report additional information based on the Error Code that is received.

Filter ID

Each filter slot has an ID magnet. These are used to position the wheel correctly.

Hand Controller

An external controller that allows the wheel to be controlled without a computer. Only supported by the IFW 2. Requires the internal hand controller power jumper to be set to on.

Homing

Optec Filter Wheels determine the number of filters and the wheel ID by homing the wheel. This is done automatically on power up and should be triggered manually by the user if a wheel is swapped or manually moved.

Sequencer

A part of the FW Control program that allows users to create simple sequences of filter moves.

USB CDC

USD CDC (communication device class) is a USB communication type that emulates serial. It operates driverless on Windows 10+, most modern Linux distributions, and macOS. The IFW 2 supports USB CDC on it’s USB port.

Wheel ID

The Filter Wheel identifies the wheel by reading the wheel ID off the magnets. The wheel ID tells the controller how many filters are available. The filter wheel stores a unique name for every filter and wheel id combination. Currently valid wheel IDs are A-K
