6. Amplifier Connections and Indicators
Transmit LED: This LED glows RED in transmit mode indicating that RF power is applied to
the amplifier from the radio.
Receive LED: This LED glows GREEN in the receive mode when DC power is applied to the
amplifier and is off when transmitting.
DC Injector Connection:
This “N” Female connector is connected to the DC Power Injector via the
transmission cable.
Antenna Connection:
This “N” Female connector connects to the antenna with a short length of coax
cable.
7. 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 Remote Transmit LED is driven by unique circuitry,
which actually detects changes in the DC current traveling 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 receive mode. When 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 2.1 mm barrel
jack. +12VDC should be applied with center positive.
