Note: It’s possible that during the update 
process any LEDs located on the USB 
flash drive may light steadily or flash with 
varying patterns. These actions are not 
significant to the Model 5150’s firmware 
update process. (The status LEDs on vari-
ous USB flash drives seem to behave in 
different ways so there are no universal 
patterns that can be identified.)
Identifying the Installed 
Firmware Versions
The four status LEDs on the front panel 
of the Model 5150 are used during the 
power-up sequence to identify the version 
number of the installed MCU and FPGA 
firmware (embedded software). While the 
display method is a bit unique, once a 
user gets accustomed to what’s actually 
happening during power up it should be 
fairly straightforward to “read” the version 
numbers.
To identify the installed firmware versions:
1. Power up the Model 5150. The four
LEDs will perform a “walk-through” 
test, with each LED briefly lighting 
in a sequence.
2. After a slight pause one of the four
LEDs will light briefly. This will indicate 
the major number of the MCU’s firm-
ware version. The LED will stop light-
ing then another one of the four LED 
will light briefly to indicate the minor 
number of the MCU’s firmware version. 
The range of each is 1-4. A period (.) is 
inserted between the major and minor 
numbers.
As an example, if the USB Activity LED 
lights first followed by the SDI Input 
LED lighting this would indicate version 
1.2 of the MCU firmware.
3. After another slight pause one of the
LEDs will light briefly. This will indicate 
the major number of the FPGA’s firm-
ware version. The LED will stop lighting 
then another one of the four LED will light 
briefly to indicate the minor number of 
the FPGA’s firmware version. The range 
of each is 1-4. A period (.) is inserted 
between the major and minor numbers.
As an example, if the SDI Input LED 
lights twice this would indicate version 
2.2 of the FPGA firmware.
4. After a final short pause the four LEDs
will begin performing in their normal op-
erating manner. The Power LED will light 
and remain lit. The USB Activity LED will 
only be active when a USB flash drive is 
inserted and file transfer activity is tak-
ing 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 configuration setting. The 
Data LED will light whenever local data 
is received via the RS-485 data bus 
from a Studio Technologies’ Model 5190 
Remote Access Module.
