Model 5154
Video Generator/Audio De-Embedder Module
reference level standard. This is because
the module’s de-embedding function simply
takes the audio data from the incoming SDI
signal and inserts it into the correct data
locations of the AES3 signal.
An interconnecting cable assembly must be
prepared with a 9-pin male D-subminiature
plug (DE-9M) on the end intended for con-
nection with the Model 5154. This cable will
interface the digital audio signals with the
9-pin female “D-sub” (DE-9F) connector
located on the back of the Model 5154.
Refer to Figure 3 for detailed connection
information.
It’s expected that four independent pieces
of coaxial cable will be used to connect
the unbalanced digital audio output signals
to the DE-9M plug, so using miniature
coaxial cable is highly recommended! The
connector pin assignments were carefully
selected to assist in efficiently making
these “hot” and “shield” connections.
As a final step, the cable assembly’s 9-pin
plug should be mated with the connector
on the Model 5154. The locking screws on
the ends of the plug should be securely
affixed to the “ears” of the connector. The
two threaded fasteners associated with the
“D-sub” use 4-40 threads.
DC Input and Data Bus
A 4-position header is used to connect DC
power and a local RS-485 serial data bus
to the Model 5154. Two pins on the mating
connector are used to connect a source
of nominal 12 volts DC. The acceptable
range is 10 to 18 volts DC with a maximum
current of 400 milliamperes at 12 volts DC.
For remote control operation two pins on
the mating connector will implement the
data bus connection from a Studio Tech-
nologies’ Model 5190 Remote Access
Module.
The mating connector is compatible with
the AMP MTA-100 series of IDC recepta-
cles. For 22 AWG wire the closed-end-style
receptacle is AMP 3-643813-4; the feed-
through-style receptacle, used for busing
connections, is AMP 3-644540-4. The body
color for both receptacles is red, following
the convention of the MTA-100 series for
compatibility with 22 AWG wire. Refer to
Appendix B of this guide for additional
connector details.

Notes:
1) Connector type on Model 5154 is a 9-pin
D-subminiature female (DE-9F). Installer must
provide a 9-pin D-subminiature male (DE-9M).
Connector uses 4-40 threaded inserts for
locking with mating plug.
2) All outputs AES3 unbalanced digital audio;
75 ohm/1 Vpp (formerly AES3id).
3) Total of eight audio channels (four “stereo”
pairs).
