For a great look it is recommended that
Brother® P-Touch ¼-inch (6 mm) labels
be created. Tape material that prints white
text on a black background works out
well for the Model 210. The Brother label
cassette number TX-3151, white on black,
is appropriate for use with many of their
printers.
In addition to the spare connector loca-
tions on the back panel, provision has
been made to allow easy interconnection
with the Model 210’s printed-circuit-board-
mounted input and output connectors.
This was accomplished by including
numerous 3-position male “header” con-
nectors on the Model 210’s circuit board.
These headers, on 0.1-inch centers, are
wired in parallel with the Model 210’s con-
nectors. This “no solder” solution makes
customizing a Model 210 a simple pro-
cess. The headers, located on the Model
210’s printed circuit board, are Molex®
part number 22-23-2031. They mate with
Molex housing number 22-01-3037. To
make the interconnection, separate crimp
terminals are attached to loose wires and
then “snapped” into the housing. Molex
part number 08-50-0114 specifies crimp
terminals that are appropriate for wires of
22 to 30 gauge. These parts are available
worldwide from sources such as Digi-Key
(www.digikey.com).
To make the process of connecting to
the Model 210’s headers a simple task
an interface cable kit, part number 31087,
is available from Studio Technologies.
Each kit includes five cable assemblies
and a length of heat-shrinkable tubing.
Each cable assembly consists of a mating
connector with three color-coded wires
attached. These wires, nominally 12
inches in length, allow convenient solder-
ing to a connector slated to be installed
in a spare location on the Model 210’s back
panel. For reference, the wire color for pin 1
is gray, pin 2 is yellow, and pin 3 is blue.
The heat-shrinkable tubing is provided
so that the connector solder cups can be
insulated from each other. It will also provide
some strain relief to the solder joints. Be
certain to slip the desired length of tubing
over the wire prior to soldering a connection!
(If the writer had a dollar for every time he
forgot to put tubing on a wire (or slip on
a connector shell) before making a solder
connection…)
The Model 210’s enclosure must be disas-
sembled prior to installing connectors in
the spare locations. Four hex-head machine
screws, two on the bottom front of the en-
closure and two on the back panel, must be
removed. A 5/64-inch hex driver is required.
The cover can then be carefully separated
from the chassis, remaining attached by
means of a flexible cable assembly. This
“flex-cable” assembly links the main printed
circuit board assembly with the board as-
sembly that contains the pushbuttons and
LED indicators. Ensure that the flex cable
is not damaged while the Model 210 is
being customized. For easier access, the
pushbutton/LED board assembly can also
be easily removed.
The 3-position headers on the Model 210’s
main circuit board assembly are located
close to their related input or output connec-
tors. The following list provides the printed
circuit board reference numbers and associ-
ated functions:
P3: Headphone output, pin 1 common,
pin 2 tip (left), pin 3 ring (right).
P4: Microphone input, pin 1 shield, pin 2
high, pin 3 low. Follows back-panel 3-pin
female XLR pin assignment.
