Rear panel

AMP203 Rear panel

All the control and configuration ports are located on the rear panel of the AMP203, 
including the (optional) 24 Volts power connection. 
 

1) 24 Volts power connection

The 24 Volts power supply connection is located on the left side of the AMP203’s rear 
panel. This power connection is an optional connection, only to be used in applications 
where the networking infrastructure is not capable of delivering (sufficient) power over 
PoE. When using this power inlet, mind the polarity when connecting the power supply.

2) Run LED:

This LED shows the operation mode / current status of the device. When the AMP203 is 
operational and running normally, the Run LED will illuminate continuously.

When powering up / booting the system, the Run LED will blink rapidly. The booting 
process will take roughly about 30 seconds when powering up the system (Blinking 
rapidly means there is no valid IP configuration available).

When the Run LED is blinking slowly (1s intervals) it means the device is being updated 
currently.

3) Ethernet connection:

The Ethernet connection is the essential connection for the AMP203. Both audio 
transmission (Dante/AES67) as well as control signals and power (PoE) are distributed 
over the Ethernet network. This input shall be connected with your network infrastructure. 
The LED’s accompanied with this input are indicating the network activity. 

4) RS485:

The RS485 input connection allows the AMP203 for being implemented with any RS-485 
compatible control device, including home or industrial automation systems or optionally 
available wall panels.
