Data
The Aux Data port is an RS-485 port. See Section 5.2 for pin assignments. In later
versions of the unit software (v. 1.17 or later), this port can be used as an input for
external metadata. This could be from the metadata output on a DP572 or from
another metadata source.

2.5.2 Audio
Connections
The digital audio inputs and Lt/Rt input are provided on female BNC connectors. The
Lt/Rt input has a loop-through connection that requires 75
Ω
termination if this
facility is not being used. The inputs should be compliant with AES3-id-1995.
There are two sets of digital audio outputs. One of the sets is from the output of the
input router, the other set is from the emulator. The digital audio outputs are provided
on a female BNC connector. The output is 75
Ω
, unbalanced, with signal levels
compliant with AES3-id-1995. There are two sets of digital outputs: channel emulator
and router outputs.
If the Cat. No. 548 Analog Option Card is fitted, then independent 5.1, two-channel and
mono analog outputs are available. These are provided on two 25-pin D-connectors.
