The EA-1 can be powered directly from the Ethernet bus if PoE (Power over Ethernet) is available. If not, it can use a 12 24 VDC standard Ophir power supply.

Besides the Ethernet Adapter itself, the package also includes:

- Brackets, screws, and an Allen wrench for mounting

There are three ways to connect to the EA-1 adapter:
- Telnet:
Establish a connection using the IP address of the EA-1. The host (e.g., PC) is considered the “client,” while the EA-1 is the “server.” - HTTP:
The IP address of the EA-1 should be entered into a regular web browser. This will show a top-level “web-page” with several buttons for accessing lower level pages. Commands can also be sent directly with the HTTP protocol. Client and server status are the same as above (Telnet). - USB virtual COM port:
For configuration and initialization only. This can be used to set the IP address for the first time or switch between dynamic and static IP address modes.
More details can be found in the EA-1 manual.
