connection (this screens the cable and acts as a
mechanical fixing for the cable, protecting the capacitor
pads).

Power connections.
5 - 15VDC (9V typically) is required to operate the
module. The lower the voltage, the less heat the module
will have to dissipate.
Locate a convenient point to connect the power. Ensure
that this point is connected after the power switch,
otherwise the DSP module will be drawing power all the
time, and may discharge the batteries (where fitted).
Connect the red wire to this point.
The 0V connection is formed using the M3 ring tag.
Locate a suitable 0V point (such as a PCB retaining screw
that is fixed into the chassis).
When routing the wires, ensure they are away from strong
sources of RF or high voltage.
