Quatech Serial PCMCIA To RS-232 2 Port Card Quatech RS-232 and RS-422/485 asynchronous serial PCMCIA cards are an ideal solution for adding additional ports to a wide variety of portable systems. 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. 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...

UPCI 8 Port Low Profile RS-232 DB9 Low Profile Universal PCI cards add serial connectivity to a variety of desktop, thin client, embedded systems, and server environments. These boards provide true universal connectivity, enabling a single product to be used to implement systems with dramatically different resource requirements. This makes Quatech boards the most robust, flexible, and economical choice for any application requiring multiple serial ports. These cards are mechanically similar to standard PCI cards, but use a shorter board and a different mounting bracket. These Low Profile Universal PCI Serial Cards utilise a single PCI slot to provide two independent asynchronous serial ports sharing a single interrupt. Multi-port versions require only one slot to connect. The cards... Less
