The 7802ec low profile PCI Express serial interface provides eight serial ports, each individually field-configurable for RS-422 or RS-485 communications. 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 7802ec ideal for data-intensive applications that require reliable, ultra-fast throughput rates.
In RS-485 mode, the board provides automatic control of the RS-485 driver in hardware, eliminating the need for application software control. This allows the 7802ec to be used with standard serial communications applications and removes the risk of bus contention and data corruption. Additionally, RS-485 network termination, critical to robust multi-drop communication, can be selectively added to the circuit via DIP-switches.
The Sealevel SeaCOM software driver and utilities make installation and operation easy using Microsoft Windows operating systems.
The 7802ec is a PCI Express X1 board compatible with any PCI Express slot. If you have a standard size PCI Express slot, be sure to select the standard profile bracket. The board ships with a 36-inch spider-cable that terminates to eight DB9M (CA231) connectors.
