Model 5150
Video Generator Module
3. Apply power to the module.
4. The module will go through its power-up
LED sequence and normal operation will
begin. At about the same time that nor-
mal 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; load-
ing 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 continuously lit.
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 5150 module. It will
go through its normal power-up LED
sequence and begin operation. It will use
the updated images whenever the inter-
nal 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 5150’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 5150 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 5150 implements a USB host func-
tion that directly supports connection of a
USB flash drive. The Model 5150 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 m5150.s19. The microcontroller is the
overall “boss” of the Model 5150, 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 m5150.bit. This firmware, running in
the FPGA, creates the video images and
processes the SDI signals. The factory will
provide updates of these firmware files if
it’s warranted for your specific Model 5150
module.
To update the Model 5150’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
m5150.s19
and m5150.bit. Be certain that any custom
image files (
img720.bmp and img1080.
bmp) are not present on the USB flash
drive during this process.
