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.
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.
• 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
(Unmarked LED on rear panel) 2-color
LED
Indicates overall status (from the rear panel):
Green = LINK and STATUS LEDs are both green
Red Flash = LINK and/or STATUS are in a yellow state; no red
states exist
Red Solid = LINK and/or STATUS are in a red state
Off = Improperly powered or fatal system failure
Read this section completely before applying power.
