Phase-out and Last Buy Notice


The MC-5157-AC/DC  series will be discontinued starting Nov. 3, 2017. The deadline for placing a final purchase order is March 25, 2018. Due to the limited availability of these products, orders will be processed till we run out of stock.


For alternative solution, please see MC-7200-MP-T or visit our Marine Computers



The MC-5157-AC/DC is a high performance, fanless marine computer. The Intel® Core™ i5 520E CPU features a 3 MB L2 cache that can easily satisfy the heavy computing loads demanded by ship-board automation systems. The fanless design further hardens this extremely rugged and reliable computer, designed from the outset for the harsh extremes of maritime environments. 


In addition to its computing power and rugged design, 2 PCI slots provide a flexibility that makes hardware extensions simple. The 8 built-in NMEA ports allow marine users to easily connect gyros, speed logs, wind sensors and other specialized maritime hardware without the headache of configuring additional NMEA converters, thereby saving money, time, and maintenance effort.

Marine ECDIS Computer White PaperECDIS Hardware and the Integrated Bridge


ECDIS Computer The marine industry’s mandated transition to the Electronic Charts Display and Information System is a revolutionary development in ships’ bridge systems. In this white paper, we show you how technological advances are aiding in modularization of bridge systems, and particularly how a new technique for calibrating color in ECDIS displays is simplifying the design and deployment of these systems....more



Marine ECDIS Computer White PaperWhite Paper:

Rugged Monitors for Harsh Environments


Moxa Rugged Monitor White PaperThe purpose of this white paper is to provide insight into what is required to design industrial-grade monitors, with particular emphasis on what design features make a monitor suitable for harsh environmental conditions. Harsh conditions could include vibrations caused by machinery, dust from manufacturing processes, as well as rain and strong sunlight for monitors located in outdoor environments. The paper addresses several issues, including (1) Mechanical Design, (2) Environmental Testing, (3) Choice of Components and Material, and (4) Electromagnetic Protection.....more
