Sealevel Systems, Inc. announces the introduction of the COMM+16.PCI, a 16-port, PCI bus serial I/O adapter that offers the highest serial port count available in a PCI format.

The COMM+16.PCI provides 16 RS-232 ports, allowing connection to PLC's, bar code readers, scales and other data acquisition/control devices.

Designed using the XR16C850 UART, the COMM+16.PCI supports standard PC data rates and boasts a top speed of 460.8K bps. The board provides a 128-byte FIFO, 16 times larger than boards designed with 16C550 parts, to allow error free operation even in high-speed applications.

Connection to the board is made through two high-density 68-pin connectors. Two single fan-out cables provide connection to each serial port through individual DB-25 male connectors for a total of 16 ports. The COMM+16.PCI also features a Universal Bus as required by PCISIG specification 2.3, allowing compatibility with today?s new 3.3V computers as well as older 5V systems.
