provide a tally function; it is intended to
illuminate the pushbutton’s clear lens and
associated labeling.
The socket in each of the pushbutton
housings was originally designed to allow
insertion of a pluggable T-1 bi-pin incan-
descent bulb. But they are also compat-
ible with the more modern leaded T-1
LEDs. As of the time of writing this guide
the specific LED used at the factory is the
Kingbright WP7104QWC/D. If backlighting
is not desired it’s easy to remove the LED
lamps. The mating socket in each push-
button assembly is accessed by care-
fully removing the pushbutton’s lens cap,
graphic label, and frosted lens. Once this
is done carefully pull on the body of the
LED and it will pull out of the socket. (A
pair of needle-nose pliers may be required
to perform this task.)
If an LED needs to be replaced note that
it is a polarized device. If upon insertion
it does not light, simply remove the LED,
rotate it 180 degrees, then re-insert it into
the socket.
MCU Firmware Update
Procedure
It’s possible that updated versions of the
firmware (embedded software) that runs
the Model 216’s microcontroller (MCU)
integrated circuit will be released to add
features or correct issues. (Contact Studio
Technologies’ technical support to review
the available firmware.) The unit has the
ability to automatically load revised files
into the MCU’s non-volatile memory by
way of its USB interface. The Model 216
implements a USB host function that di-
rectly supports connection of a USB flash
drive. The Model 216’s MCU updates us-
ing a file named m216.bin.
The update process begins by preparing
a USB flash drive. The flash drive doesn’t
have to be empty (blank) but must be in the
personal-computer-standard FAT32 format.
Save the new firmware file in the root direc-
tory with a name of m216.bin. Studio Tech-
nologies will supply the MCU file inside
a .zip archive file. While the firmware file
inside of the zip file will adhere to the nam-
ing convention required by the Model 216,
the name of the zip file itself will include
the MCU file’s version number. For exam-
ple, a file named m216v1r2MCU.zip would
indicate that version 1.2 of the firmware
( m216.bin) is contained within this zip file.
Once the new file is loaded into the Model
216 the 2-digit LED display should be used
to confirm that the correct firmware version
has been successfully installed.
To install the firmware file follow these
steps:
1. Remove power from the Model 216.
This will entail removing the Ethernet
connection if it is providing PoE power
and/or removing the external source of
12 volts DC if that is being used.
2. Ensure that nothing is present in the
USB port. Then again apply power to
the unit and “read” the currently loaded
firmware version using the 2-digit LED
display. Note this for later reference.
3. Remove power from the Model 216.
4. Insert the prepared USB flash drive
into the Model 216’s USB port, located
on the back panel of the unit.
5. Apply power to the Model 216. Power
can be provided by Power-over-Ethernet
(PoE) associated with a connected
Ethernet signal or can be from an
external 12 volt DC source.
