7205ec ULTRA COMM+2.PCIe Low Profile PCI Express 2-Port RS-232, RS-422, RS-485 Serial Interface

Description

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 ratesexceeding

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 devicedriver. Additionally, the Windows driver provides a software-selectable

Slew Rate Limiting feature to minimize electromagnetic interference where high baud ratesare 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, be sure to select the standard profile bracket. The 7205ec is RoHS compliant and meets the

requirements of RoHS (2011/65/EU) directive.
