Eddy-S1/DB9-PoE
This module can operate as a powered device (PD), which accepts power input from the twisted pair
Category 5 Ethernet cable as specified in IEEE 802.3af Power-over-Ethernet (PoE) standard.
With a backup 5V DC power jack, power supply can be automatically channeled to 5V adaptor when
PSE (Power Sourcing Equipment) is out of order. Seamless power supply is guaranteed. PSE power can
be used again when the PSE is in normal operation.
For serial communication, RS232 only or RS422/485 combo interface is available through DB9 male
connector. In the combo module, RS422/485 setting can be adjusted with software, using web
interface.
