4. After a few seconds the USB Activity
LED will go out and the FPGA firmware 
version will be displayed by the eight 
Digital Audio Inputs Signal Present 
LEDs. The top row of four LEDs will 
display the major version number with 
a range of 1-4. The bottom row of four 
LEDs will display the minor version 
number with a range of 0 (no LED lit) 
to 4. Refer to Figure 10 for details.
5. After a final short pause the LEDs will
begin performing in their normal op-
erating manner. The Power LED will 
remain lit. The USB Activity LED will 
only be active when a USB flash drive 
is inserted and file transfer activity is 
taking place. The SDI Input LED will 
light whenever a valid SDI signal is 
connected to either the coaxial (BNC) 
input or the optical input, depending on 
the module’s capability and configura-
tion setting. The Data LED will light 
whenever local data is received via the 
RS-485 data bus from a Studio Tech-
nologies’ Model 5190 Remote Access 
Module. If digital audio input signals 
have been configured to be embedded 
their associated Digital Audio Inputs 
Signal Present LEDs will light whenever 
signal levels are –40 dBFS or greater.
Once a user gets accustomed to what’s 
actually happening during power up it 
should be fairly straightforward to “read” 
the version numbers.
SFP Module Flexibility
The Model 5152 was designed to allow an 
MSA-compliant SFP optical module to be 
installed at the factory. Optical modules are 
available with a range of input and output 
capabilities to meet the needs of various 
applications. For maximum flexibility the 
SFP mating connector and associated 
“cage” on the Model 5152’s FPGA circuit 
board were implemented to meet the elec-
trical and mechanical requirements of the 
MSA SFP standard. The MSA SFP stan-
dard was originally developed for use with 
optical data (Ethernet) modules. It has 
also become popular for use with SFP 
modules that support SMPTE-compliant 
SDI signals.
It’s interesting to note that several compa-
nies offer non-optical SFP modules that 
support the MSA SFP standard as well. 
For example, Embrionix of Canada offers 
a wide range of specialized SFP modules. 
These include coaxial SDI input and output 
modules that use DIN 1.0/2.3 and HD-BNC 
connectors. In addition, they offer SFP
