PCM Serial Configuration

The NetAcquire H30-SIO performs as a low-cost real-time communications gateway between Ethernet networks and high-speed PCM serial devices. Network clients such as engineering workstations can now receive and send telemetry as well as command data directly from and to range, satellite and avionics communications equipment. The NetAcquire H30-SIO also supports data format conversion operations, frame synchronization, time tagging, header generation, and optional decommutation; all with best-in-class low latency real-time performance. An extensive suite of real-time processing functions is available without the need for programming.

The NetAcquire H30-SIO industry-standard TCP/IP & UDP network interfaces provide communication access for a wide variety of computers and operating systems on any Ethernet network; it also provides integrated support for publish/subscribe network protocols including DDS.

NetAcquire offers several companion software toolkits for use with these systems. The NetAcquire Server Extension Toolkit allows the easy creation of custom data processing operations for execution in real-time on the NetAcquire H30-SIO.

Preston Hauck

President, Chief Technology Officer

Preston Hauck founded NetAcquire in 1993 with the goal of providing computer communications and processing systems that seamlessly operate with real-time performance over distributed networks.

During the early years of NetAcquire, Preston took a hands-on role in developing new products. He remains enthusiastically involved in helping customers solve complex real-world challenges.

As the company grew, Preston leveraged his information systems background to create tools that could automate business processes, increasing company efficiency, responsiveness, and scalability. In his current role, Preston oversees new product direction, manages company growth,works directly with clients and the engineering team on projects that call for his applications design expertise.

Prior to founding NetAcquire, Preston served as vice president of software engineering for Microstar Laboratories, a provider of PC-based test and measurement products. During his tenure, he helped the company grow tenfold in both revenue and employees. Preston developed an innovative real-time operating system from the ground-up, plus a data processing engine that powered all of Microstar's products for more than two decades.

Preston holds a bachelor's degree in computer science, graduating first in his class in 1984 from the University of British Columbia.  He was granted a U.S. patent for developing a novel approach to initialize one processor from another in a multi-processor system. He has published a number of papers on real-time computer systems and regularly teaches networked telemetry processing classes.

Preston was born in Canada. After many years living in Washington State, he proudly became a naturalized U.S. citizen in 2003. He enjoys traveling, reading, photography, basketball, skiing, and movies with his wife Colleen and their two children.

John Bono

Engineering Vice President

John Bono, a Seattle area native, graduated summa cum laude with a Bachelor of Science in Electrical Engineering from the University of Washington.  John started his career with Boeing Aerospace Company, working in a variety of roles. He received personal recognition from Boeing’s CEO for his contributions to 767 avionics.  John designed hardware and firmware for a Mil-Std-1553 bus interface and was the hardware lead and system designer for a B-1B flight simulator’s computer generated imagery display.  After Boeing, John joined Advanced Technology Laboratories (ATL) as a signal processing engineer. He was promoted to the role of ultrasound system architect before becoming the software and systems lead for an image storage and network transport system. During John’s tenure at ATL, he received a Technical Fellow award, became a member of the Senior Technical Staff, and had a role in ATL’s achievement of ISO 9001 certification.  

When John joined the rapidly growing NetAcquire Corporation in 2001, his “big company” experience was leveraged to enhance configuration management and quality systems and processes. He soon became the Management Representative for the company’s AS 9100 certification efforts.  

Today, John is involved in the system, hardware, and firmware design of virtually every system NetAcquire ships.  While the majority of these systems are customer-specified configurations of NetAcquire COTS hardware and software modules, many other systems are rack-sized, challenging configurations involving complex interchanges of information in all forms.  The NetAcquire motto of “connect anything to anything” is John’s daily mission; he knows that, when applied to real-time systems, there will be a continuous stream of interesting problems to solve and challenges to conquer to best meet the needs of his customers and their mission critical projects around the world.

Steve Proudlock

Sales Vice President

For many NetAcquire customers, Steve is the initial face and voice of the company. While he has a desk at the company headquarters in Kirkland, Washington, quite often he’s in the air, flying to meet customers, discuss projects and set solutions into motion.

Steve joined NetAcquire in the summer of 2001. He sees his principal role as being the customer’s advocate. Steve thrives on opportunities to work on-site with NetAcquire customers to see first-hand the tasks and challenges they face.

In 2002, Steve joined the volunteer organizing committee for the International Telemetering Conference; he serves on the committee to this day. Steve also supports and participates in the meetings and industry standards efforts of several Range Commanders Council (RCC) committees.

Steve is an Army Veteran, having served in locations around the world in military law enforcement and personal protection roles. After graduating Pre Law from Central Washington University, he began a sales career in retail consumer electronics. The career choice was inspired by his favorite uncle, Ken Cartwright, a career tire salesman at Sears. Ken taught Steve the foundation principles of professional salesmanship: “Say what you are going to do, and then do it,” and “Get to know someone by showing sincere interest and earning their trust”.  

Steve’s Microsoft and Cisco certifications help him better understand the technical aspects of test range telemetry. While Steve is well versed in all aspects of NetAcquire technology today, he still learns something new on a daily basis from his colleagues.

Steve is a Seattle area native who enthusiastically gives his time and resources to a local charity dedicated to supporting foster children and their families.
