Connect the other end of the coaxial cable
to the Power Injector side marked MOD.
Connect the DC power supply to the Power
Injector and plug in to an AC power source.
A 12V DC camera may be powered from
the modulator, however the power
supply rating must increase 100mA
in addition to the camera requirement
to allow for the modulator.
FOR EXAMPLE: If your camera
requires 12V DC 300mA then use a
12V DC 400mA transformer or larger.
