Model 5152
Video Generator/Audio Embedder Module
Typically both .bmp files will be updated at
the same time. But there’s no requirement
to do so. Individual files can be updated
whenever desired. Simply copy the desired
file or files to the root directly on the USB
flash drive. Be certain that there are no
Model 5152 firmware files (m5152.s19 and
m5152.bit) present on the USB flash drive
during this process.
As previously reviewed in this guide, the
1280 x 720 image must have a file name of
img720.bmp; the 1920 x 1080 image must
have a file name of img1080.bmp. Also
ensure that both have the DIB header type
BITMAPINFOHEADER so that they can be
recognized correctly by the Model 5152.
To install the new image files:
1. Power down the Model 5152 module.
2. Insert the prepared USB flash drive into
the module’s USB port.
3. Apply power to the 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. Load-
ing both .bmp files will take approxi-
mately 6.5 minutes. (Loading only the
img720.bmp file takes approximately
2 minutes; loading only the img1080.
bmp file takes approximately 4.5 min-
utes.) Once the loading process has
been completed the USB Activity LED
will change from flashing 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 image. (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 5152 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 5152’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 5152 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 5152 implements a USB host func-
tion that directly supports connection of a
USB flash drive. The Model 5152 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 m5152.s19. The microcontroller is the
overall “boss” of the Model 5152, doing
