Model 5152
Video Generator/Audio Embedder Module
Operation
Power Up
Upon 12 volt DC power being applied to
the Model 5152 the 12 front-panel LEDs
will perform a “walk-through” test, with
each LED briefly lighting in sequence.
Upon completion, the Power LED will
light continuously. 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 5152’s
status LEDs will be covered in this section.
Front-Panel LEDs
As previously discussed, upon power up
the front-panel LEDs will light in a short se-
quence as an initialization test. Afterwards
they are used to display the version num-
ber of the installed firmware. Refer to the
Technical Notes section of this guide for
details. Following the power-up sequence,
the Power LED will light and remain lit.
The USB Activity LED will not light during
normal Model 5152 operation. It will be
continuously lit 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
5152 to a Studio Technologies’ Model 5190
Remote Access Module. The LED will flash
on and off each time data associated with
this specific Model 5152 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.
The eight LEDs associated with the digital
audio inputs will light whenever signal is
present on their associated audio channels
and embedding of these signals into the
SDI signal is taking place. Details regard-
ing the functioning of these LEDs are
included later on in this section.
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 5152 power up each LED will
light for several brief durations with no spe-
cific meaning associated with them. Then
the FPGA Status LED, located adjacent to
the configuration switches, will light and re-
main lit. This indicates that the FPGA and
MCU boards are correctly communicating.
The LED located adjacent to the coaxial
SDI input’s BNC connector will light when-
ever that input has been configured to be
active and a valid SDI signal is connected.
It will not light if a valid SDI signal is con-
nected but the SDI input configuration
switch is not set to activate the coaxial
(BNC) input.
The LED located adjacent to the “cage”
that holds an optical SFP module will light
if the optical SDI input has been selected
and a valid SDI optical signal is connected.
