[. . . ] Serial PCMCIA Cards RS-232 and RS-422/485 Quatech serial PCMCIA cards (PC Cards) provide a simple yet robust solution for adding multiple serial ports to laptops, notebooks, tablets, handhelds and embedded systems. [. . . ] For example: POS Systems Field data collection Quatech serial PCMCIA cards add one, two or four RS-232 or RS-422/485 ports to portable computers. Features and Benefits One, two or four independent serial ports RS-232 or RS-422/485 cards Speeds up to 921. 6 kbps Auto enable/disable feature for RS-422/485 transmitter Ruggedized case with removable cable standard Permanently attached ruggedized cable option for one and two port RS-232 cards 3. 3V and 5V compatible RoHS compatible Medical testing Kiosks GPS tracking The most complete serial PCMCIA product line available Quatech offers more choices in serial I/O PC cards than any other manufacturer, including several exclusive models. In addition, our PCMCIA cards use a single driver set for all models, making them an extremely practical choice for applications with multiple configurations that span several operating systems including Windows, Linux and OS/2. Quatech PC Cards are small, light and have low power requirements to reduce battery drain. They are available with one to four independent RS-232 or RS422/485 serial ports that share a single interrupt. The standard version comes with a convenient detachable cable. For extreme computing environments, permanently attached ruggedized cables are available. Mobile office Industrial monitoring & control Industry leading speeds mean exceptional performance Quatech serial PCMCIA cards provide industry leading speeds of up to 921. 6 kbps by employing a clock multiplying feature in conjunction with 16750 UARTs. [. . . ] To further increase performance, we have created an auto toggle feature for the RS-422/485 transmitter that permits the hardware itself to regulate data flow by only driving lines while actively transmitting--providing increased speed and convenience over the older software controlled method.
