The 7105 PCI serial interface provides one serial port configurable for RS-422, RS-485, or RS-530. The board is capable of data rates to 460.8K bps and automatically handles RS-485 transmitter enable/disable. The 7105 utilizes a 16C850 UART to provide 128-byte Tx/Rx FIFOs for maximum reliability in data intensive applications.

Sealevel SeaCOM software makes installation and operation easy using Microsoft Windows and Linux operating systems.

The 7105 is compatible with standard 5V PCI slots.
