Model 5150
Video Generator Module
MOTION= selects the status of the 
Moving Image Overlay function. There 
are two choices. 
OFF disables the Moving
Image Overlay function.
ON enables the
Moving Image Overlay function.
SDIMODE= selects the status of the SDI 
Mode function. There are two choices. 
NORMAL selects that a valid SDI signal 
connected to the selected SDI input will 
pass through to the module’s SDI output(s). 
REFONLY selects that the SDI input will 
serve only as a timing reference signal. The 
internally-generated image will always be 
sent to the SDI output(s).
GPI= selects the status of the GPI (general-
purpose input) function. DISABLED selects 
that the function is not active. Future ver-
sions of the MCU firmware may implement 
other GPI actions. Note that if the hardware 
version of this specific Model 5150 does not 
support the GPI function this text line can 
be part of the file but will not be recognized.
GPO= selects the status of the GPO 
(general-purpose output) function. 
DISABLED selects the function to be not 
active. SDIVALID selects the GPO output 
to be high when a valid SDI signal is con-
nected to the selected SDI input (coaxial 
(BNC) or optical). SDINOTVALID selects 
the GPO output to be high when a valid SDI 
signal is not connected to the selected SDI 
input (coaxial (BNC) or optical); the GPO 
output will be low when a valid SDI signal is 
connected. Note that if the hardware version 
of this specific Model 5150 does not support 
the GPO function this text line can be part 
of the file but will not be recognized.
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 lighting briefly 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 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 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. 
Following 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.
