2-Channel UART Serial I/O PMC Adapter

The 2-Channel UART Serial I/O PMC (PCI Mezzanine Card) Adapter provides two RS232 channels of simultaneous, bi-directional UART (Universal Asynchronous Receiver/Transmitter) serial communications. The adapter is available in both conduction-cooled (CC) and air-cooled versions : ruggedised, industrial and commercial.

Architecture

The 2-Channel UART Serial I/O PMC Adapter employs a PCI-based dual-channel, high performance, industry standard 16550 compatible UART.

Features

Minimal option for low-cost systems or systems that require more UART-compatible serial communication links than offered by the host.

Allows direct low-level control of the serial communication links.

Conduction-Cooling

The conduction-cooled 2-Channel UART Serial I/O PMC Adapter conforms to the CCPMC (Conduction-Cooled PCI Mezzanine Card) Standard, namely ANSI/VITA 20-2001.

Applications

Distributed applications in harsh environments

Avionics

Mission-critical applications
