Mon, 09/26/2011 - 7:41am

Sealevel Systems, Inc. (Liberty, SC) has introduced the COMM+4 PCIe serial interface, for expanding serial communications in a variety of test and measurement, process control, and point-of-sale applications. The interface provides four multifunction serial ports, each individually field-configurable for RS-232, RS-422, or RS-485. Each serial port utilizes a 16C954 UART with 128-byte Tx/Rx FIFOs that enables data rates to 921.6K bps for reliable high-speed communications. This UART includes 9-bit framing support and is register compatible with legacy software applications designed for 16C550 UARTs. In addition, the board derives a 62.5 MHz clock from the PCI Express bus.
