Model 5152
Video Generator/Audio Embedder Module
Configuration
Ten DIP switches are used to configure 
the Model 5152’s operating functions. The 
functions relate to SDI input selection, 
audio embedding configuration, SDI output 
image rate/format mode, RS-485 address, 
and moving image overlay. The ten switch-
es are located on the two circuit boards 
that comprise the Model 5152. Five of the 
switches are on the FPGA board which is 
the lower board. 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.
Switch 1 on the FPGA board is used to 
select which SDI input will be 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 opti-
cal input is selected. Of course the optical 
input will only function if a factory-supplied 
SFP module is physically present.
Audio Embedding
One of the strengths of the Model 5152 is 
its ability to select which of the four digi-
tal audio inputs will be active and where 
their signals will be embedded into the 
SDI output “stream.” Switches 2, 3, and 4 
on the FPGA board are used to configure 
the embedding function, allowing selection 
from among eight choices.

SDI Input Select
The Model 5152 is capable of having its 
SDI input in the form of a coaxial signal 
(BNC connector) or an optical signal (SFP 
module). Each version of the Model 5152 
supports 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.
