Video Generator/Audio De-Embedder Module
4. After a few seconds the USB Activity
LED will go out and the FPGA firm-
ware version will be displayed by the
eight Digital Audio Inputs Signal Pres-
ent LEDs. The top row of four LEDs will
display the major version number with
a range of 1-4. The bottom row of four
LEDs will display the minor version num-
ber with a range of 0 (no LED lit) to 4.
Refer to Figure 9 for details.
5. After a final short pause the LEDs will
begin performing in their normal operat-
ing manner. The Power LED will remain
lit. The USB Activity LED will only be ac-
tive when a USB flash drive is inserted
and file transfer activity is taking place.
The SDI Input LED will light whenever
a valid SDI signal is connected to either
the coaxial (BNC) input or the optical
input, depending on the module’s capa-
bility and configuration setting. The Data
LED will light whenever local data is
received via the RS-485 data bus from
a Studio Technologies’ Model 5190 Re-
mote Access Module. Digital audio sig-
nals being de-embedded will have their
associated Digital Audio Outputs Signal
Present LEDs will light whenever their
signal levels are –40 dBFS or greater.
Once a user gets accustomed to what’s
actually happening during power up it
should be fairly straightforward to “read”
the version numbers.
SFP Module Flexibility
The Model 5154 was designed to allow an
MSA-compliant SFP optical module to be
installed at the factory. Optical modules are
available with a range of input and output
capabilities to meet the needs of various
applications. For maximum flexibility the
SFP mating connector and associated
“cage” on the Model 5154’s FPGA circuit
board were implemented to meet the elec-
trical and mechanical requirements of the
MSA SFP standard. The MSA SFP stan-
dard was originally developed for use with
optical data (Ethernet) modules. It has
also become popular for use with SFP
modules that support SMPTE-compliant
SDI signals.
It’s interesting to note that several compa-
nies offer non-optical SFP modules that
support the MSA SFP standard as well.
For example, Embrionix of Canada offers
a wide range of specialized SFP modules.
These include coaxial SDI input and output
modules that use DIN 1.0/2.3 and HD-BNC
connectors. In addition, they offer SFP
modules that provide an HDMI® output.
Several of these modules have been in-
stalled and tested in Model 5154 modules
at the factory and acceptable performance
was confirmed. It’s possible that special
applications could benefit from the features
provided by installing these non-optical
SFP modules in a Model 5154. For further

USB Port Capabilities
The USB port, accessible on the Model
5154’s front panel, is provided for use in
only a few specific tasks. While it imple-
ments a high-speed USB host interface,
it is not intended for general-purpose use
and does not support connection with
mass-storage devices, personal comput-
ers, printers, etc. It is intended only for use
with USB flash drives. These devices can
contain image and firmware files that are
intended for loading into the Model 5154.
Details on these file-transfer functions can
be found in other sections of this guide.
