IP Former TPA400
Quick Install Guide
The Barix IP Former TPA400 is an audio over IP decoder which includes an amplifier to drive a loudspeaker.
STEP 1 Connect the loudspeaker
Connect any 2 to 8 ohm loudspeaker using the screw terminal connector. (device is optimized for 4 and 8ohms)
STEP 2 Connect to a PoE switch
Connect your IP Former to a PoE switch using a standard Ethernet cable (CAT5e or better). The class negotiated is Class 0, which will allow the switch to deliver up to the maximum capability per port (power available at PD for 802.3af <= 12.95W). IP Former drains maximum 6W.
Some IP Former modules were observed to have issues when connected to few industrial switches, namely the Moxa EDS-P510A-8PoE and the Phoenix Contact 1000. When connected to these switches SOME modules enter in a power loop. If possible please try to avoid using those switches or any other switch providing a Voltage at PD (powered device) less than 46VDC.
When current flows from the switch the device boots:
Right after power-up both status LEDs are red (boot in process)
20s after power-up → Device announces its IP Address (take note to be able to enter the web interface later) → Left LED turns from red to green
40s after power up → Application is ready → Right LED turns from red to green
IP Former is ready to be configured.
First Configuration - Play Barix Radio
From a PC in the same network subnet of the device, use a web browser to access the web interface by typing the IP Address into your browser (the one noted during boot)
