Hardware requirements
For most situation you would want to use the optical/infrared interface. For that, you will need an IR optical read-out head with serial (or serial-to-USB) interface.
Using Ali-Express: 'USB to optical interface IrDA near-infrared magnetic adapter' this is confirmed working with the MULTICAL® 403 (IR head positioned upside down).
Note that a magnet is required to enable the IR circuit, but it's not strong enough to maintain the position of the head on its own. You would still want to find a way to mount the head for a permanent installation.
