Indicators
4.1.3 Control Overview
There is only one external control on the EX-5i, a button labeled “RMT” (Remote). This button
allows the user to easily and quickly evaluate the status of the remote end radio. Press and hold
the button and, while held, all local end status LEDs (Link, Status, Radio A) represent the status
of the LEDs on the remote end radio. In addition, the RSL voltage also represents the voltage
that is present at the remote end.
When the amber LED that is embedded in the RMT is flashing, this is an alert that the remote
end has an alarm condition, and the button should be pressed to determine the alarm conditions.
When the RMT button is pressed and held, and the local LEDs flash, there is no remote end
information 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 the local or remote radio.
Examining local end LEDs (when this button is not pressed) in combination with the 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.
4.2 Applying
Power
The radio requires a DC power source within specifications, as stated. The DC may be provided
from a DC battery source, central lab/rack supply or from the AC adaptor supplied. Read this
