The APPI-401A is a passive PoE injector card, which allows a chain of up to three Picos to be powered from an ADAU chassis.
Axon Picos are compact all-in-one PoE powered and daisy-chainable DAUs. This reduces cabling weight by getting the data acquisition closer to the sensors.
The APPI-401A provides one PoE (combined power and data) interface that connects to one end of an Axon Pico chain and one Ethernet pass-through (data only) interface for connecting to a switch or the second Ethernet port of the Overhead in the chassis.
