Model 5152
Video Generator/Audio Embedder Module
EMBED= selects how audio signals con-
nected to the Model 5152’s digital audio
inputs are to be embedded into the SDI
output signal. The first digit represents what
is to happen to the audio associated with
digital audio inputs 1 and 2. The second
digit represents what is to happen to the
audio associated with digital audio inputs
3 and 4. Each digit can be either
N, 1, 2,
3, or 4. The digit N indicates that the digital
audio inputs are not to be embedded. The
numbers 1, 2, 3, and 4 represent the SDI
group that the digital audio inputs are to be
embedded into. The [CONFIGURATION]
section of Figure 8 shows
EMBED=12
which indicates that digital audio inputs 1
and 2 are being embedded into SDI group
1 and digital audio inputs 3 and 4 are being
embedded into SDI group 2.
GPI= selects the GPI (general-purpose
input) function. DISABLED selects that the
function is not active.
EMBEDOFF selects
that the GPI will control the on/off status of
the Model 5152’s embedder function. Note
that if the hardware version of this specific
Model 5152 does not support the GPI func-
tion (modules with serial numbers 00250
or less) this text line will not appear.
GPO= selects operation of the GPO
(general-purpose output) function. Five
choices are available. DISABLED selects
the GPO function to be inactive. It will
remain logic low and not change state.
SDIVALID selects that the GPO will be
high when a valid SDI signal is connected
to the selected SDI input (coaxial (BNC)
or optical). SDINOTVALID selects that the
GPO will be high when a valid SDI signal
is not connected to the selected SDI input
(coaxial (BNC) or optical); the GPO will be
low when a valid SDI signal is connected.
EMBEDON selects that the GPO will be
high when the embedder function is active.
EMBEDOFF selects that the GPO will be
high when the embedder function is not
active; the GPO will be low when the em-
bedder is active. Note that if the hardware
version of this specific Model 5152 does
not support the GPO function (modules
with serial numbers 00250 or less) this text
line will not appear.
Configuration Text File
A text file can be created to specify how a
Model 5152 should be configured. Saved
on a USB flash drive, the file must have
a name of CONFIG.TXT and be stored
in a folder directly under the root with a
name of M5152. When the USB flash drive
is plugged into a Model 5152 the file will
automatically be read and the configura-
tion stored. Immediately after the file is
read the STATUS.TXT file will be written to
the M5152 folder. The contents of this file
will reflect the configuration that’s pres-
ent after the contents of the CONFIG.TXT
have been read. This will provide immedi-
ate feedback that the desired configuration
has be implemented.
The following paragraphs detail the con-
figuration choices. Refer to the Figure 9
for a sample file. This information is also
shown in the [OPTIONS] section of the
STATUS.TXT file, described previously
in this guide.
The text lines that follow the [CONFIGU-
RATION]
heading should remain in the
same order as shown in the example. (But
technically they are not required to do so.)
All configuration items are not required to
be present but for clarity it’s recommended
that they are. The text is case sensitive and
must follow the example.
