GPS + UART Serial I/O PMC Adapter

The GPS + UART Serial I/O PMC (PCI Mezzanine Card) Adapter provides an integrated GPS (Global Positioning System) receiver plus one channel of UART (Universal Asynchronous Receiver/Transmitter) serial I/O. An external DGPS (Differential GPS) input is provided. The adapter is available in both conduction-cooled (CC) and air-cooled versions : ruggedised, industrial and commercial.

Architecture

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

Features

This board offers full GPS functionality to be integrated with the host in addition to an extra UART-compatible serial communication link.

Conduction-Cooling

The conduction-cooled GPS + 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
Position tracking applications
