Model 5154
Video Generator/Audio De-Embedder Module
“house” timing signal. An operating mode
selection allows an HD- or 3G-SDI signal
to serve as a timing reference.
When the SDI Mode is set for Normal
a signal connected to the Model 5154’s
selected SDI input will pass through to the
SDI output(s). When SDI Mode is set for
RefOnly the timing, rate, and format of the
input SDI signal will impact the internally-
generated video image output. The video
information associated with the input signal
will not be routed to the SDI output(s).
Configuring this mode can be performed
using the Model 5190 Remote Access
Module or by way of a text file stored on
a USB flash drive.
Audio De-Embedding
One of the strengths of the Model 5154
is its ability to select which audio groups
from the SDI input will be de-embedded
and routed to the four digital audio outputs.
Eight configuration selections allow a wide
range of de-embedding choices.
Six of the de-embedding choices are pro-
vided so that any combination of the four
SDI audio groups (1, 2, 3, and 4) can be
de-embedded. The last two de-embedding
choices provide a unique DA (distribution
amplifier) function for applications where
audio data is only present in group 1 or
group 2.
Viewing Module Details
An associated Model 5190 Remote Ac-
cess Module can be used to directly view
firmware (embedded software), hardware,
and configuration details about a Model
5154 module. In addition, the Model 5154
incorporates a unique standalone method
of providing these details. This is accom-
plished by the module creating a simple
text file which is stored on a USB flash
drive. This file can then be easily viewed
using a personal computer. Information
provided in the file includes firmware ver-
sion numbers, hardware serial number, and
configuration settings. The information pro-
vided in the text file can provide assistance
when configuring, using, and troubleshoot-
ing Model 5154 modules.
Each time a Model 5154 detects that a USB
flash drive has been connected a text file
will be created and stored. The file, named
STATUS.TXT, will be stored in a folder
named M5154 which is one level below the
root of the USB flash drive. If the folder is
not already present it will be created. If a
STATUS.TXT file is already present a new
one will automatically be written over it.
The Model 5154 does not have a method
of accessing the current date or time, i.e.,
no real-time clock. This limitation requires
that a fixed file creation date be used and
12/31/1979 was selected. However, the time
stamp continues to advance in real time
until a power cycle occurs.
The text contained in the STATUS.TXT
file is organized into three sections. The
following paragraphs provide a detailed
explanation. Refer to Figure 7 for a display
of a sample file.
STATUS.TXT File – [SYSTEM INFO]
The [SYSTEM INFO] section of the
STATUS.TXT file provides general informa-
tion about this specific Model 5154 module.
PRODUCT= identifies the module’s product
type. For the Model 5154 it will be listed as
M5154. This information is provided as a
confirmation for situations where multiple
STATUS.TXT files are being examined.
