Highlighted fields

The source address and port number fields are highlighted in green (as shown above) when the

enabled receiver receives an audio stream from the specified source. The two fields are marked

in red when no stream is received with the audio receiver enabled and correctly configured.

Two-way audio

The figure above shows the setup for two-way audio on the side of the A-80. The device on the

other side of the connection (with the IP address 172.22.250.131) would need similar settings,

that is - it must hold the IP address of the A-80 as the destination and source. Transmitters and

receivers must be enabled in order for streaming to start. Remember to Save a configuration to

make it effective.
