Model 5150
Video Generator Module
When switch 5 on the MCU board is in its
off (up) position the stored images (“720”
and “1080”) will be displayed without the
moving image being added. When the
switch is in its on (down) position the mov-
ing image will be added.
Note that the characteristics of the image
(color, size, and movement) can’t be modi-
fied. The image overlay function is created
in firmware (embedded software) with no
provision for users to alter it.
Operation
Power Up
Upon 12 volt DC power being applied to
the Model 5150 the four front-panel LEDs
will perform a “walk-through” test, with
each LED briefly lighting in sequence.
Then the LEDs will light in patterns that
represent the version numbers of the
firmware (embedded software) files that
are loaded into the module. Upon comple-
tion, the Power LED will continuously light.
For normal operation to commence, prior
to powering up the module ensure that
a USB flash drive is not plugged into the
USB port on the front panel.
LED Indicators
A brief discussion of the Model 5150’s sta-
tus LEDs will be covered in this section.
Front-Panel LEDs
As previously discussed, upon power up
the four front-panel LEDs will light in a
short sequence as an initialization test.
Afterwards they are used to display the
version number of the installed MCU and
FPGA firmware. Refer to the Technical
Notes section of this guide for details. Fol-
lowing the power-up sequence, the Power
LED will light and remain lit.
The USB Activity LED will not light during
normal Model 5150 operation. It will be lit
continuously or in a pattern when a USB
flash drive is plugged into the USB port
on the front panel and file transfer activ-
ity is taking place. Details on how the LED
functions when the USB port is active are
covered in the Technical Notes section of
this guide.
The SDI Input LED lights whenever a valid
SDI signal is connected to the coaxial
(BNC) or optical SDI input. (A configuration
choice selects whether the coaxial (BNC)
SDI input or optical SDI input is active.)
The Data LED will light whenever data ac-
tivity is taking place over the local RS-485
signal bus that is used to link the Model
5150 to a Studio Technologies’ Model 5190
Remote Access Module. The LED will flash
on and off each time data associated with
this specific Model 5150 is present. Not all
applications will include a connection to
the data bus so it’s certainly possible that
the Data LED may never flash except dur-
ing module power up.
FPGA Board LEDs
Three LEDs are located on the back edge
of the FPGA printed circuit board and
serve as factory- and field-diagnostic aids.
Upon Model 5150 power up each LED
will light for several brief durations with
no specific meaning associated with them.
Then the FPGA Status LED, located
adjacent to the configuration switches,
will light and remain lit. This indicates that
the FPGA and MCU boards are correctly
communicating.
