The Ethernet port of the Digi Connect EM embedded module (labeled P12) is an 8-pin
RJ-45 jack meeting the requirements of ISO 8877 for 10/100Base-T. When two
descriptions are shown for a pin, the second is for use with 802.3af powered Ethernet.
For additional information about the 802.3af standard, refer to the corresponding IEEE
specification.
Note
The GPIO port is a 10-pin male right-angle connector (labeled P3). See the following
figure and table for pin orientation and pin assignments.
GPIO Port Pin Orientation
The development board provides a reference design of a POE (Power Over
Ethernet) power supply. A schematic for this reference design is installed by
the setup program on the CD.
