7205ec overview

Description
Downloads

The 7205ec low-profile PCI Express serial interface provides two serial ports configurable for RS-232, 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 7205ec ideal for data intensive applications that require reliable, ultra-fast throughput rates.

The electrical interface, echo suppression and line termination are set via convenient on-board DIP switches, which can be overridden by the Windows device driver. Additionally, the Windows driver provides a software-selectable Slew Rate Limiting feature to minimise electromagnetic interference where high baud rates are not required. For rapid troubleshooting, on-board LEDs display the board heartbeat, electrical interface selection and line termination state.

In RS-485 mode, the transmitter is automatically enabled in hardware for Windows applications, eliminating the need for software control. This allows the 7205ec to be used with standard serial communications applications and removes the risk of bus contention and data corruption. In RS-232 mode, all modem control signals are implemented for maximum compatibility with a wide range of serial peripherals.

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

The 7205ec is a PCI Express [x1] board compatible with any low profile PCI Express slot. If you have a standard size PCI Express slot, please request the 7205ecS-ROHS version. The 7205ec is RoHS compliant and meets the requirements of RoHS (2011/65/EU) directive.

The board ships with a 36" cable that terminates to two DB9M connectors.
