Model 5154
Video Generator/Audio De-Embedder Module
4. The module will go through its power-
up LED sequence and normal opera-
tion will begin. At about the same time
that normal operation starts the new
.bmp files will begin to load, one after
the other. The USB Activity LED on the
module’s front panel will flash while the
loading process is taking place. Loading
both .bmp files will take approximately
6.5 minutes. (Loading only the img720.
bmp file takes approximately 2 minutes;
loading only the img1080.bmp file takes
approximately 4.5 minutes.) Once the
loading process has been completed the
USB Activity LED will change from flash-
ing to being lit continuously.
Note: If the module is currently output-
ting one of the stored images and a new
image of the same type (“720” or “1080”)
has just completed loading, the output
will automatically change to the new im-
age. (It’s possible that a few seconds of
a solid color could be output during the
transition from the old image to the new
image.)
5. Power down the module.
6. Remove the USB flash drive from the
module’s USB port.
7. Power up the Model 5154 module. It
will go through its normal power-up LED
sequence and begin operation. It will
use the updated images whenever the
internal SDI generator is active.
It’s possible that during the update process
any LEDs located on the USB flash drive
may light steadily or flash with varying pat-
terns. These actions are not significant
to the Model 5154’s update procedure.
(The status LEDs on various USB flash
drives seem to behave in different ways
so there are no universal patterns that
can be identified.)
Firmware Update Procedure
It’s possible that updated versions of the
firmware (embedded software) that runs
the Model 5154 will be released to add
features or correct issues. The module
has the ability to automatically load re-
vised files by way of its USB interface. The
Model 5154 implements a USB host func-
tion that directly supports connection of a
USB flash drive. The Model 5154 uses two
firmware files to perform its functions. One
file is used by the microcontroller inte-
grated circuit (MCU) and has a file name
of m5154.s19. The microcontroller is the
overall “boss” of the Model 5154, doing
pretty much everything but the SDI-related
tasks. The other firmware file is used by
the logic chip (FPGA) and has a name of
m5154.bit. This firmware, running in the
FPGA, creates the video images, pro-
cesses the SDI signals, and handles audio
de-embedding. The factory will provide up-
dates of these firmware files if it’s warrant-
ed for your specific Model 5154 module.
To update the Model 5154’s firmware is
quite simple but requires careful execution.
The process begins by preparing a USB
flash drive. The flash drive doesn’t have
to be empty (blank) but must be in the
personal-computer-standard FAT32
format. Save the new firmware files in
the root directory. Their names must be
m5154.s19 and m5154.bit. Be certain
that any custom image files (img720.bmp
and img1080.bmp) are not present on the
USB flash drive during this process.
Studio Technologies will supply the MCU
and FPGA files inside individual .zip
archive files. While the firmware file inside
of each zip file will adhere to the naming
convention required by the Model 5154,
the name of the zip file itself will include
