The 7106 Low Profile PCI serial interface provides one serial port configurable for RS-232, RS-422, RS-485, or RS-530. The board is capable of data rates to 921.6K bps and automatically handles RS-485 transmitter enable/disable. The 7106 utilizes a 16C850 UART to provide 128-byte Tx/Rx FIFOs for maximum reliability in data-intensive applications. The board is MD1 Low Profile and Universal Bus (3.3V and 5V) compatible.

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

The 7106 is compatible with any low profile PCI slot. A standard profile bracket  is also included.

NOTE: The 7106, when ordered with standard profile bracket, is a form, fit, and function replacement for the 7103 PCI serial adapter.
