The schematics are the best reference for the development system. The next few sections

will explain the different parts of the development system. Take a look at the schematics

for further details.

2.1.1 Input Power

It can be powered from the input power or the USB connector X1. Powering the system

from the USB cable is not recommended because of the voltage drop in the USB cables

and the USB Hubs. If using USB for power, connect the USB cable directly to the PC.

Connecting both the USB cable to X1 and power source to X7 is completely safe.

2.1.2 Ethernet

For network connectivity, the development system includes the required Ethernet

connector with built-in magnets.

2.1.3 USB Device (Virtual COM)

This is connected to a USB<->serial converter chip to COM1 of Embedded Master

Module. Drivers need to be loaded when this connector is plugged into the PC for the

first time.
