Description

The 7204ec low-profile PCI Express serial interface provides two serial ports configurable for RS-422 or RS-485. Each serial port features an ultra high-speed UART, flexible clock prescalar, and large 256-byte Tx/Rx FIFOs allowing the adapter to support the widest range of standard and non-standard baud rates exceeding 1 Mbps. These features make the 7204ec ideal for data-intensive applications that require reliable, ultra-fast throughput rates.

In RS-485 mode, the transmitter is automatically enabled in hardware, eliminating the need for application software control. This allows the 7204ec to be used with standard serial communications applications and removes the risk of bus contention and data corruption.

The Sealevel SeaCOM software driver and utilities make installation and operation easy using Microsoft Windows operating systems.

The 7204ec is a PCI Express X1 board compatible with any low profile PCI Express slot. If you have a standard size PCI Express slot, be sure to select the standard profile bracket. The board includes a 36-inch cable that terminates to two DB9M connectors.
