Quatech SSP-200/300 - Serial adapter - PC Card - RS-422, RS-485

Quatech SSP-200/300 - Serial adapter - PC Card - RS-422, RS-485
Add reliable, high-speed serial ports for connecting card readers, barcode scanners and other serial devices to laptop, tablet and handheld PCs. Available in 1, 2 and 4 ports for RS-232 or RS-422/485, and ruggedized (permanently attached cable) for 1 and 2 port RS-232. One of the most complete and robust Serial PCMCIA cards in the marketplace, Quatech PCMCIA cards can expand a mobile system’s capabilities while taking up minimal system resources. Because they share electronic fundamentals with native bus architectures such as PCI and ISA, they function exactly like standard COM ports and can be addressed as such by most application software. In addition, their small size and the fact that the card itself can be left inside the computer at all times, make them practical choices for the ‘most mobile’ portable systems.Quatech Serial PCMCIA cards are designed to provide maximum performance while taking up minimal system resources. For high performance in heavy multitasking environments, the cards are implemented with 16750 UARTs containing 64-byte FIFOs. This along with Quatech’s special clock-multiplying feature enables data transfer rates as high as 921.6 kbps. (4-port cards still use 16550 UARTs for standard 115.2 kbps speeds, but are due for an upgrade soon.) The cards also conserve system resources with their low power requirements that maximize battery life. They also have selectable and shareable interrupts, further extending a portable or handheld system’s limited resources. And their multi-platform operating support makes them the single practical choice for a diverse fleet of portable systems.Synchronous Serial PCMCIA Cards are also available (RS-232 and RS-422/485).PRODUCT FEATURES: 3.3V and 5V compatible; Fastest data rates; Lower power requirements.
