be configured through the front panel (Section 3.2.3.1) or the M&C (Section 4.2). PAD
data is output through the port labeled PAD on the back of the receiver. Please see
section 7.9 for information on the PAD port pin-out.
2.9.1 In-Band Ancillary Data
In-band ancillary data is raw asynchronous data embedded within the streaming audio on
the same program PID as the audio. It is fed into the RS232 port of the encoder port and
thereby associated with a single audio stream. MP2 natively supports ancillary data.
AAC will be carry ancillary data in a proprietary enhancement to the framing protocol
(this enhancement will be compatible with all AAC decoders).
2.9.2 Out-of-Band Ancillary Data
Out-of-band ancillary data is raw asynchronous data associated with a single audio
stream but carried outside of the MP2 or AAC data frame. It is fed into the RS232 port
of the encoder port and thereby associated with a single audio stream. This data may be
embedded within the MPEG2 transport framing structure (TSP) of a single audio stream.

Connecting the Modem
If you do not have access to an always-on internet connection in your station, the PRO4-P
is equipped with a dial-up modem. Please see section 3.2.2.1 for information on
configuring Dial-Up through the front panel.
3 FRONT PANEL OPERATIONS
The front panel of the PRO4-P Receiver is equipped with an interface that allows users to
navigate through the hierarchical menu to view, modify and save receiver settings. The
Four status LEDs are indicative of the power, signal, update and fault states of the
receiver. Users interact with the receiver by using the eight buttons:
1

Status LEDs
Each of the four status light-emitting diodes indicates a specific state of the receiver. The
following sections provide details on reading the status of the receiver based on the
LEDs.
