Connector Interfaces
--------------------

100BASE-TX / USB
::::::::::::::::

.. image:: Assets/RMDEthConn2.jpg
   :scale: 100%

This side of the device has two standard RJ-45 jacks for the two 100BASE-TX ports.

+-------+--------------------------+
| ETH1  | Left Connector           |
+-------+--------------------------+
| ETH2  | Right Connector          |
+-------+--------------------------+


The USB Type C connector provides power to the device as well as data connection to a host PC.  If only powering the device is needed, a standard USB charger rated for 1A or more can be used.  

.. admonition:: Caution
   :class: attention

   Using a USB power source rated for less than 1A may cause the device to malfunction and possibly even damage it.


100BASE-T1 
::::::::::::::


.. image:: Assets/RMDAEConn.jpg
   :scale: 100%

This side of the device has a single connector for the two 100BASE-T1 ports.  The connector/terminal part numbers and pinout are shown below.
