SEA-7106e

7106e ULTRA530.LPCIe Low Profile PCI Express 1-Port RS-232, RS-422, RS-485, RS-530 Serial Interface

Description

The 7106e low-profile PCI Express serial interface provides a single serial port configurable for RS-232, RS-422, RS-485 or RS-530. The ultra high-speed UART, flexible clock prescalar, and large 256-byte Tx/Rx FIFOs allows the adapter to support the widest range of standard and non-standard baud rates exceeding 921.6 K bps. These features make the 7106e 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 7106e 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 7106e 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 7106e is RoHS compliant and meets the requirements of RoHS (2011/65/EU) directive.
