PCMCIA is the classic way of adding serial connectivity to laptops. Increasingly new laptops are coming without PCMCIA slots and using the new ExpressCard slots instead.

The PCMCIA range includes 1 or 2 ports in either RS232 or RS422/485 serial connectivity. As standard most PCMCIA cards have removable cables terminating in a 9 pin D connector. Ruggedised PCMCIA cards have permanently attached cables for increased security.


ExpressCard dimensions

PCMCIA stands for Personal Computer Memory Card International Association, the group of companies that defined and developed the standard. While this acronym did clearly describe the original intentions of the organization's standard, it was difficult to say and remember, and was sometimes jokingly referred to as "People Can't Memorize Computer Industry Acronyms". Later PCMCIA was rebranded to simply PC-Card. PC-Cards were superseded by ExpressCards in 2003, laptops manufactured after this time are more likely to have ExpressCards.
