Keyspan USB to Serial Adapter 2 Port RS-422 Mac
There's a good reason why Keyspan's Mac USB serial adapters outsell those of other companies. Their years of experience making PCI serial cards for Macintosh make them more knowledgeable about Macintosh serial technology. Keyspan applied their expertise to produced the first USB serial adapter for MacOS in October 1998. Now, as others introduce their initial solutions, Keyspan is leading the way with a second generation adapter which delivers faster speeds and broader compatibility! The new USB Twin Serial Adapter supports all Apple StyleWriters, Apple Personal LaserWriters, Epson Stylus Color Printers, HP DeskWriters and serial HP DeskJets! Expanded compatibility is just one of enhancements included in the new USB Twin Serial Adapter. This new model also delivers faster performance -- allowing HP printers, for example, to print 4 times faster than the previous adapter. Backed by Synchrotech's one year limited warranty and highly trained technical support, the only thing you will have to worry about is finding new uses for the card!
