The ideal solution for adding serial connectivity to a wide variety of desktop, server and embedded systems, Quatech Serial PCI and Low Profile Serial UniversalPCI Boards are the most reliable in the industry. Quatech Serial PCI boards utilize a single PCI slot to provide two independent asynchronous serial ports that share a single interrupt. Multi port versions available, two, four, and eight ports, require only one slot to connect to additional serial devices. The cards include a fan out cable with independent DB-9 male connectors. All PCI registers are properly implemented, so you can be assured that Quatech boards will be good citizens on the PCI bus. Serial port connections are made via DB-9 male connectors. The boards are implemented with 16550 UARTs containing 16-byte FIFOs and data rates up to 115.2 kbps. To maintain maximum signal integrity, Quatech uses a four-layer board design to insure maximum protection versus noise propagation throughout the communication lines. The Quatech DSLP-PCI-100 is configured to fit into low profile systems utilizing only one PC slot with a fanout cable to connect two serial devices. An optional bracket is available to allow the card to fit into standard height machines.
