Connections
All connections are clearly indicated
on the module. AES audio I/O
connections can be made two ways,
by directly wiring connections to a
suitable male 25pin SubD connector,
or by using a RBO 5025 optional
25pin SubD PCB adapter with screw
terminals.
Operation
The PDM 1284 D functions as a 4 channel embedder and de-embedder.
Simultaneous embedding and de-embedding is also possible. For
example, its possible to de-embed and output audio from a selected
audio group before overwriting it with new audio.
Rotary switches are provided for AES 1+2 and AES 3+4 audio group
selection, and a 1KHz tone can also be selected (all channels).
Note: An audio “group” is 2 x AES.
Settings
A dip switch is provided for
module conguration. Settings are
indicated on the module and self
explanatory.
The“Auto Black” function will switch in a black test signal if the input video
is lost, allowing for an uninterrupted audio connection. This mode also
allows the module to be used to transport audio signals alone if required.
Sample rate converters can be turned o to support encoded AES streams
such as DolbyE.
Optional Fiber
Optional Fiber I/O can be added at anytime by plugging in the Fiber SFP
sub module. This will provide 3Gbit SDI ber I/O capability (ber input is
selected via the dip switch).
Power
The module requires a 12V DC power input and a LED is provided to
conrm power is connected.
RBO 5025: 25 Pin SubD Adapter PCB with
screw terminals

Cascading Modules
If more than 2 x AES channels are required then its possible to cascade
multiple modules. Take the SDI out from one module and connect to
the input of another module and select a dierent audio group. Up to 4
modules can be cascaded to embed the full 8 x AES audio payload into a
single SDI stream.
Power Lead Strain Relief
The module has a small hole in the case located above the power con-
nection. To prevent the power lead being accidentally pulled out, use the
supplied tie-wrap and secure the lead as shown below.
Optional Mounting Bracket
The optional RFR 1001 mounting bracket can be used to permanently
mount the module on any at surface or on 19” rack rails.
Note: Another module is shown for reference. PDM 1284 D is identical in terms of
mounting and securing.
