The spare connector locations are com-
patible with the Neutrik DL-series of con-
nectors. For flexibility, XLR versions are
available that provide from three to seven
contacts. For example, a compatible 3-pin
female connector would be Neutrik part
number NC3FD-L-1. The NC6FDS-L-1 is
often used to support headsets. This is a
6-pin female connector with the unique
Switchcraft® 6-pin arrangement. Other
connectors, such as the etherCON pro-
tected RJ45 and 3-conductor ¼-inch jack,
can be also be installed. The 4-40 thread-
pitch hardware that secures the blank
plates to the Model 214’s back panel are
also intended to secure the replacement
connectors.
If connectors are added to the Model
214’s spare connector locations adding
labels to them can be helpful. 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 214. The Brother label cassette
number TX-3151, white on black, is appro-
priate for use with many of their printers.
The Model 214’s enclosure must be dis-
assembled prior to installing connectors
in the spare locations. Four hex-head
machine screws, two on the bottom front
of the enclosure 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” assem-
bly links the main printed circuit board
assembly with the board assembly that
contains the pushbutton switches and
LED indicators. Ensure that the flex cable
is not damaged while the Model 214 is
being customized.
3-Position Headers
In addition to the spare connector loca-
tions on the back panel, provision has
been made to allow easy interconnection
with the Model 214’s printed-circuit-board-
mounted input and output connectors.
This was accomplished by including sev-
eral 3-position male “header” connectors
on the Model 214’s circuit board. These
headers, on 0.1-inch centers, are wired in
parallel with some of the Model 214’s con-
nectors. This “no solder” solution makes
customizing a Model 214 a simple pro-
cess. The headers, located on the Model
214’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 three loose wires
and then “snapped” into the housing.
Molex part number 08-50-0114 specifies
crimp terminals that are appropriate for
22 to 30 gauge wires. These terminals are
available worldwide from sources such as
Digi-Key (www.digikey.com).
To make the process of connecting to the
Model 214’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, approximately 12
inches in length, allow convenient solder-
ing to a connector selected to be installed
in a spare location on the Model 214’s
back panel. For reference, the wire color
for pin 1 is gray, pin 2 is yellow, and pin 3
is blue.
