• Connect a fixed (or a series of fixed) 50-Ohm attenuator(s) to the RF connector,
either directly or at the end of an RF transmission line. The attenuator must be at least
30dB as specified at the operating frequency (~2400 MHz for the EX-2.4i; ~4950
MHz for the EX-4.9i, ~5700 MHz for the EX-5i), and rated for a minimum of 1W
input power. Examples include:
¶ Broadwave Technologies P/N 352-103-xxx
¶ Bird 2-A-MFN-xx
¶ JFW Industries 50FP-xxx-H6-N
AC Power
The AC adapter easily connects to the device. The AC rating of the adapter accepts most
standard voltages and frequencies worldwide. Refer to the input voltage requirements
stated on the label affixed to the adapter to ensure that the adapter can be used with the
AC mains supply.
The AC plug outlet provided with the adapter may need to be replaced to match the
country configuration. The adapter cable uses a standard connector for this cable for use
of a pre-wired cable appropriate to the outlet configuration. If the appropriate cable is not
available, the existing AC plug end can be severed and a replacement plug affixed.
Consult a qualified electrician for this activity.
Do not plug the adapter into the mains power. First, verify that the RF connector is
properly terminated (see Power on page 41), and then plug in the radio-side connector
from the AC adapter to the radio. If the AC mains can be turned off using a switch,
disable the power, plug the AC side of the adapter into the AC mains socket, and then
enable power to the circuit. If the AC mains cannot be turned off, plug in to the AC main
socket to apply power.
Verify that the radio is active by observing LED activity. All LEDs on the radio flash at
initial power cycle.
It is strongly encouraged that the AC mains supply be fused or on a separate breaker to
ensure against over-voltage and/or over-current situations and to provide some form of
protection to the radio electronics and other devices connected to the same supply. In
addition, if the AC power is subject to significant spikes or variation, power conditioning
is a worthwhile investment, as the quality of mains power may have a direct impact on
the device operation, performance and/or reliability. An Uninterruptible Power Source
(UPS) or other form of battery-backed system protects against brown-out and black-out
conditions, and condition the power presented to the adapter.
Evaluate the opportunity for lightning or other similar surges to be present on the
powering system, including the ability for surges to couple to the power wiring system. If
an evaluation indicates that there is a potential likelihood for these conditions to occur,
additional surge protection is recommended for the input power wiring, especially to
protect the radio electronics between the adapter and the radio’s DC input connector.
The above statement is similarly true for every wired connection to the device. While the
configuration for surge suppression or line conditioning is of a different type for each
