PCI Serial I/O Adapter Provides 16 RS-232 Ports

The COMM+16.PCI, a PCI bus serial I/O adapter, provides users with 16 RS-232 ports for connection to PLCs, bar code readers, scales, and other data acquisition and control devices. Employing an XR16C850 UART, the adapter supports both standard data rates and a maximum speed up to 460.8 Kb/s. A 128-byte FIFO, claimed as 16 times larger than boards designed with 16C550 devices, is included to promote error-free operation in high-speed tasks. Connection to the board is via two 68-pin connectors. Two single fan-out cables are included for connection to each serial port through DB-25 male connectors. Other adapter features include a USB interface to satisfy the PCISIG specification 2.3 for compatibility with 3.3V and 5V systems. The adapter (product number 7161) is available from stock and is priced at $599 each. SEALEVEL SYSTEMS INC., Liberty, SC. (864) 843-4343.
