MODEL 206
ANNOUNCER’S CONSOLE
here to the naming convention required by
the Model 206, the name of the zip file itself
will include the file’s version number. For
example, a file named m206v1r1MCU.zip
would indicate that version 1.1 of the ap-
plication firmware (m206.bin) is contained
within this zip file.
Once the USB flash drive is inserted into
the USB interface, located on the main cir-
cuit board under the cover, the unit must be
powered off and again powered on. At this
point the file will automatically load. The
precise steps required will be highlighted in
the next paragraphs of this guide.
To install an application firmware file follow
these steps:
1. Disconnect power from the Model 206.
This will entail removing the Ethernet
connection that is providing PoE power.
2. Remove the cover from the Model 206.
Use a #1 Philips head screw driver to
remove six machine screws, two on
the top edge of the back panel, one on
each side of the unit, and two on the
front edge of the bottom surface. Be
certain to save the screws so that re-as-
sembly will be fast and painless. Then
carefully slide the cover forward, rotat-
ing it forward 180 degrees once it has
cleared away from the three level poten-
tiometers. Be very careful not to kink or
damage the small ribbon interconnect-
ing cable.
3. Locate the USB connector on the main
circuit board. It’s near the front of the
unit, directly between the channel 1 and
channel 2 potentiometers. Insert the
prepared USB flash drive into the con-
nector.
4. Apply power to the Model 206 by con
-
necting to a Power-over-Ethernet (PoE)
Ethernet source.
5. After a few seconds the Model 206 will
run a “boot loader” program that will
automatically load the new application
firmware file (m206.bin). During this
time period an LED, located adjacent
to the USB connector, will slowly flash
green. Once the loading process is
over, taking approximately 10 seconds,
the Model 206 will restart using the
newly-loaded application firmware.
6. At this time the Model 206 is function-
ing with the newly-loaded application
firmware and the USB flash drive can
be removed. But to be conservative, re-
move PoE power first and then remove
the USB flash drive.
7. Confirm that the desired firmware ver-
sion has been correctly loaded. This
can be done by pressing and holding
the talkback 3 button, applying power
to the Model 206, and then “reading”
the application firmware version num-
ber by first observing the main button’s
green LED and then observing the
talkback 1 button’s red LED. Alternate-
ly, the STcontroller application can be
used to identify the application firmware
version number. Whatever method you
use, ensure that the desired version is
present.
8. Once the update process has been
complete reverse the steps and re-at-
tached the cover using the six machine
screws.
