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. 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 represents the remote-
end voltage.
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.
Note: Read this section completely before applying power.
Terminating the RF Connector
Before applying power, the device’s RF connector 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.
There are a few simple means to accommodate 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.
