1.3.1 Ethernet and PoE
The EL-500 has a 10/100 Ethernet port that supports passive Power over Ethernet (PoE). The
PoE power injector should supply an input voltage between 9-28VDC and a minimum of 12W.
The pinout for the Ethernet interface on the EL-500 is provided in Table 3.
The EL-500 is equipped with an auto-sensing Ethernet port that allows both regular
and cross-over cables to be used to connect to it.
