Ethernet vs USB? Which is better for communicating and automating test equipment and devices? Is it easy to implement Ethernet on an embedded system?

USB vs Ethernet for Test Equipment? 

  • Ethernet comes with free isolation
  • No drivers required to get Ethernet working
  • USB is faster to get working depending on your network hacking skills
  • USB software stacks in test equipment are kinda hit or miss

How to make hardware work with Ethernet?

  • Still learning about this
  • Trying out Arduino -> Ethernet shields that use the Wiznet W5100
  • Managed to get a demo working with SCPI and the shield

Tag Connect : Edge-Connect

Bias test connector – OTC (one time connect)

  • PEM smtsss-4mm-6et solderable spring standoffs
  • Use in conjunction with through hole pogo pins
  • Just add holes and target points on main pcb and plug the connector in for access to the nets

About the Hosts

Parker dillmann
  Parker Dillmann

Parker is an Electrical Engineer with backgrounds in Embedded System Design and Digital Signal Processing. He got his start in 2005 by hacking Nintendo consoles into portable gaming units. The following year he designed and produced an Atari 2600 video mod to allow the Atari to display a crisp, RF fuzz free picture on newer TVs. Over a thousand Atari video mods where produced by Parker from 2006 to 2011 and the mod is still made by other enthusiasts in the Atari community.

In 2006, Parker enrolled at The University of Texas at Austin as a Petroleum Engineer. After realizing electronics was his passion he switched majors in 2007 to Electrical and Computer Engineering. Following his previous background in making the Atari 2600 video mod, Parker decided to take more board layout classes and circuit design classes. Other areas of study include robotics, microcontroller theory and design, FPGA development with VHDL and Verilog, and image and signal processing with DSPs. In 2010, Parker won a Ti sponsored Launchpad programming and design contest that was held by the IEEE CS chapter at the University. Parker graduated with a BS in Electrical and Computer Engineering in the Spring of 2012.

In the Summer of 2012, Parker was hired on as an Electrical Engineer at Dynamic Perception to design and prototype new electronic products. Here, Parker learned about full product development cycles and honed his board layout skills. Seeing the difficulties in managing operations and FCC/CE compliance testing, Parker thought there had to be a better way for small electronic companies to get their product out in customer's hands.

Parker also runs the blog, longhornengineer.com, where he posts his personal projects, technical guides, and appnotes about board layout design and components.
