The OptoSpin25 and OptoSpin32 are fully supported in the following software packages via USB control:

  • MicroManager

  • MetaMorph / MetaFluor

  • NIS Elements


For other software packages, the OptoSpin position can be controlled externally using TTL high signals from an appropriate data interface. 

Alternative Control Method (TTL)

We provide a breakout cable with BNC connections, which requires:

  • 3 TTL highs to encode the stepping position (via encoded bits)

  • 1 TTL high to step the wheel (labeled GO)


This configuration allows control of two filter wheels from one power supply using 7 TTL highs (as the GO command is for both wheels simultaneously). 

The control lines are identical for both OptoSpin25 and OptoSpin32.


Additional Hardware Support

We commonly use a NIDAQ (National Instruments) card and driver to generate these signals.

Any Dig I/O interface that is compatible with your imaging software can also be used.

We can supply the National Instruments interface if required.
