This adapter controls the Thorlabs FilterWheel FW102B and FW212B. A manual can be found here. Note that the filter wheel has a USB connection. The software that comes with the filterwheel will install a driver for USB to serial converter that appears as a serial port in Micro-Manager. If such a driver can be found on Mac or Linux, this adapter will work on those platforms too (please share experiences here).
