VL-EPMs-U1

Description

Overview

The VL-EPMs-U1 module provides advanced serial communications and Global Positioning System (GPS) capabilities in embedded systems. Based on the SUMIT-104 form factor, the VL-EPMs-U1 supports SUMIT and PC/104™ stackable expansion buses. With a compact rugged form factor and low power consumption (700 mW typ.), the VL-EPMs-U1 is well suited to size, weight, and power constrained applications. A full industrial temperature rating and certification to MIL-STD-202G specifications for shock and vibration ensure reliable operation in harsh, mobile, and/or remote environments.

Like all VersaLogic products, the VL-EPMs-U1 is designed to support OEM applications where high reliability and long-term availability are required. From application design-in support, to its 5+ year production life guarantee, the VL-EPMs-U1 provides a durable embedded computer solution with an excellent cost of ownership. The VL-EPMs-U1 is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.

Details

With up to six serial ports, the VL-EPMs-U1 provides traditional hardwired serial I/O functions for legacy communications. RS-232 serial ports operate in 4-wire mode at 115 Kbps; RS-485 mode adds auto-direction control and high-speed 460 Kbps transmission.

When equipped with the optional Trimble® Lassen® iQ GPS receiver, the VL-EPMs-U1 delivers complete position, velocity, and time (PVT) data for use in host applications. The Lassen iQ provides simultaneous 12-channel operation for stable satellite tracking and aided GPS startup for fast initial signal acquisition. Dual GPS signal sensitivity modes enable reliable tracking in difficult environments with weak satellite signals. GPS data is available in popular NMEA, TSIP, TAIP, or DGPS protocols. The GPS data is accessed through two on-board serial ports. An antenna with interface cabling is available for evaluation, testing, and software development.

Designed for full industrial (-40° to +85°C) temperature operation; the VL-EPMs-U1 is built to withstand thermal extremes and meets MIL-STD-202G specifications for mechanical shock and vibration. Transient voltage suppression (TVS) devices on the serial port I/O lines provide enhanced electrostatic discharge (ESD) protection for the system. Fault protection on the GPS antenna guards against open and short circuits.

Based on an industry standard 16C550 I/O controller, the VL-EPMs-U1 is fully compatible with a variety of popular operating systems including Windows, Windows Embedded, Linux, VxWorks, and QNX using standard serial I/O software drivers.
