Power
The radio requires a DC power source within specifications. DC can be provided from a DC battery
source, central lab/rack supply, or from the supplied AC adapter.
Terminating the RF Connectors (EX-4.5r-c GigE and EX-5r-c GigE)
Before applying power, the RF connectors must be properly terminated into a 50-Ohm load. If this is
not performed, the radio may be damaged by simply applying power. Also, there are human safety
factors to consider regarding potentially harmful RF radiation.
The following lists a few simple ways to achieve proper termination:
• Connect a 50-Ohm coaxial termination device to the RF port of the radio. The termination must be
rated to 1W (or more). Example(s) include:
– Broadwave Technologies P/N 552-200-002, or similar
• Connect the complete transmission system. That is, the RF cabling including the antenna. The
cabled antenna provides a proper termination for the RF output.
• 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 (~5700 MHz) 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
Cover any unused connector with the connector cap and apply the weather-seal tape. Both cap and tape
are included in the accessory kit.
AC Power
The AC adapter easily connects to the power injector. 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
), 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
