DC Power Injector Connections and Indicators
A DC Power Injector is an in-line device which “injects” the DC power necessary to operate the
amplifier onto a transmission line. This allows the cable to carry both RF signals and DC power to
the mast-mounted amplifier.
Transmit LED:
This LED glows RED when the pole mounted amplifier goes into the transmit mode. The
Transmit LED is driven by unique circuitry, which actually detects changes in the DC cur
r
through the transmission line to the amplifier.
Receive LED:
This LED glows GREEN when DC power is applied to the amplifier and it is in the recei
v
toggling between transmit and receive this LED will glow slightly dimmer.
To Radio
Connection:
This “N” Female connector is connected to the radio modem via a short jumper cable.
To Amplifier
Connection:
This “N” Female connector connects to the amplifier on the mast via the transmission line
12 VDC:
This is the DC power input for the injector and is a standard 2.1mm barrel jack. +12VDC
applied with center positive.
Power Supply
The AMP2440 comes with power supplies that have standard 2.1 mm barrel plugs (which are
configured as positive (+) tip and negative (-) outer conductor). Although normally supplied with a
power supply, any regulated 12 Volt DC 1 amp supply can be used. The power supply can be used
with 110 or 240 VAC power.
Operation
The unit operates automatically and there are no user adjustments.
The amplifier is only intended for use with the BreezeNET Radios. These radios “ping pong” back
and forth between transmit and receive so quickly, during normal operation, that both the TX and RX
LEDs will appear to be lit simultaneously. In fact, they are turning on and off so quickly that they
appear to be on all the time. You can tell how quickly one of these LEDs are turning on and off by
their brightness. Their glow will be slightly dimmer when they are off.
