RMT (Remote) Button
The RMT button is the only external control on the radios. This button allows easy and quick
evaluation of the status of the remote-end radio. When the RMT LED is amber flashes, this is an alert
that the remote end has an alarm condition. Press the RMT button to determine the alarm conditions.
When the RMT button is pressed and held and local LEDs flash, this indicates that no remote-end
information is available. This indicates that the remote radio is either not powered, is booting, or is
not linked in the direction towards the local radio, or the local radio is receiving excessive errors in
this direction. It could also indicate a serious failure of either radio.
Local-end LEDs (when this button is not pressed) in combination with remote-end information (from
a technician located at the far end, and/or when the button is pressed) can substantially aid in rapid
troubleshooting analysis.
Power
The radio requires a DC power source within specifications. The DC can be provided from a DC
battery source, central lab/rack supply, or from the supplied AC adapter.
Read this section completely before applying power.
The TO ODU Connector
When power is applied to the IDU, the
TO ODU
connector exhibits DC voltage between the center
pin and ground.
Warning:
Do not touch the center connector pin when power is connected. There is risk of
electric shock if the
TO ODU
connector center pin is touched by persons or tools.
Disconnect power from the IDU before connecting coaxial cable(s) or any other devices (such as
surge arrestors) between the
TO ODU
connector and the ODU.
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
), 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.
