Keyspan USB twin serial adaptor (MAC ONLY)

Connect two mini Din-8 serial devices to a USB port

Capable of RS-232 and RS-422

There's a good reason why we sell more Mac USB serial adapters than any other company. Our years of experience in making PCI serial cards for Macintosh make us much more knowledgeable about Macintosh serial technology.

We applied this expertise to produced the first USB serial adapter for Mac OS in October 1998. As Apple released Mac OS X, we added Mac OS X drivers for the Twin Serial Adapter.
This adapter is recommended by dozens of serial devices manufacturers and this adapter has been certified by Apple for use with Final Cut Pro (to connect to external video decks).
