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.
