E-Plex is a hardware and software solution for power distribution and system control. • E-Plex Hardware “Modules” can be grouped in 6 categories: Electronic Control Modules DC Power Distribution & Digital IO AC Power Distribution Sensing User Interfaces Equipment Interfaces • E-Plex “E-Logic” software has 3 purposes Design – How the system will function and look. Generate documentation. Program – Configuration of generic hardware for application specific purposes Test – Verify the system is operating as expected. Identify

• E-Plex is unique because it sends data and power over the same wire. • Powered by a patented multiplexing technology that allows power and data to be transported over a simple, two-wire bus. • With just two wires, E-Plex provides all the benefits associated with multiplexing with less cost, complexity and weight. • Two Wires… T

• E-Plex operates from 7v-30v and uses full battery potential to generate its digital signal. Electrical noise induced onto the E-Plex bus can be easily distinguished from data signals. Costly shielding or termination resistors are not required. • When E-Plex modules receive the command, data is transmitted in an appropriate time-slice and the clock immediately echoes it back. The node then checks the data received back from the clock for errors. The Clock and nodes on the bus calculate a checksum of the entire packet and data is rejected and immediately resent if these checksums do not...

Message-Based relative to Master/Slave (E-Plex) • In a message-based system each individual data packet contains all of the information needed to establish its priority and to make sure traffic on the bus is managed • Advantages – No “traffic cop”, Modules are independent • Disadvantages – Data collisions happen, high-speed on the bus required to manage large data packets • In a master/slave system a main controller manages data communication on the bus • Advantages – No data collisions, small data packets allow lowbandwidth general, speed/bandwidth drive cost • Disadvantages –
