Model 5150
Video Generator Module
Configuration
Seven DIP switches are used to configure
the Model 5150’s operating functions. The
functions relate to SDI input selection, SDI
output image format/rate mode, RS-485
address, and moving image overlay. The
seven switches are located on the two cir-
cuit boards that comprise the Model 5150.
Two of the switches are on the FPGA
board which is the lower board. (There is
a total of five switches on the FPGA board
but only two are used to configure Model
5150 functions.) The other five switches
are on the MCU board which is the upper
board. The switches are a “piano key” type
with their up position being defined as off
and their down position defined as on.
SDI Input Select
The Model 5150 is capable of having its
SDI input in the form of a coaxial signal
(BNC connector) or an optical signal (SFP
module). All versions of the Model 5150
support the coaxial (BNC) input. The opti-
cal input is an option and may or may not
be present on the specific module you are
configuring.
Switch 1 on the FPGA board is used to
select which SDI input is active. When the
switch is in its off (up) position the coaxial
(BNC) input is selected. When the switch
is in its on (down) position the optical input
is selected. Of course an optical input will
only function if a factory-supplied SFP
module is physically present.

SDI Output Image Format/
Rate Mode
Switch 5 on the FPGA board is used to
configure how the format and rate of the
internal SDI generator is selected. (The in-
ternal SDI generator creates the solid-gray
video image and plays back the custom
“720” and “1080” images.) When the switch
is in its off (up) position the format and rate
will automatically “follow” that of the con-
nected SDI input. This allows the Model
5150 to automatically “learn” the specific
format and rate used by a broadcast facility
or live event.
