signal on to another unit; if pass-through is not necessary, this connector should be
fitted with a 75-ohm terminator.
The Digital In connectors, AES 1 and AES 2, can receive both Dolby® Digital and
PCM signals. The decoder recognizes each signal type and processes the signal
appropriately. Digital inputs can also be received using the Optical In and 100BASE-T
inputs shown in Figure 2-2.
The LTC Out connector provides a SMPTE 12M linear timecode output signal.
Timecode is extracted from the timestamp embedded in a SMPTE 337M bitstream
that may be present in a Dolby Digital signal.
The Digital Out connectors provide a digital output signal for connection to a digital
monitoring system. Each connector is labeled according to the channel pair it
contains.

The Optical In connection can receive both Dolby Digital and PCM signals. The
decoder recognizes each signal type and processes the signal appropriately.
The 100BASE-T port can connect to a 100Base-T or 10Base-T network. The
connection can then be used for streaming audio, and to enable the DolbyRemote 564
remote control application. See Chapter 8, Streaming Server and Remote Software,
for details.
The Remote RS-485 port can connect to a computer running DolbyRemote 564. The
DolbyRemote 564 application is far more efficient, however, when connected via the
100BASE-T port. For details, see Chapter 8, Streaming Server and Remote Software.
The GP I/O port connects to the Dolby Cat. No. 549 GPIO Controller (sold separately)
or to a separate remote control device, which must be configured according to the
pinout information under GPI/O Configuration in Section 4.4.4, I/O Control.
