Lynx.GX Installation and Management
FAR END
When the LED on this button is red, alarms exist on the far-end radio. Press and hold the button to view
those alarms on this radio’s front panel. If the far-end radio is not available, such as when the link is down,
all LEDs flash red.
Note: Pressing and holding this button while powering on the radio resets the IP address settings and
passwords to default values.
ORDERWIRE Port
This connection is used to access the electronic orderwire function (a facility for telephone style service from
one radio to another). A standard analog telephone (with an electronic ringer) plugs into this RJ-11
connector. You can dial the orderwire address of the far-end radio (or any radio in the network) to cause
that radio and any connected orderwire phone to ring; however, communications is automatically
established when both telephones are lifted off hook.
This communication does not interrupt or interfere with the other radio communications. The radio link must
be operational to use this facility. The orderwire feature can be very useful for installation, maintenance, and
troubleshooting.
Note: All radios connected to the same orderwire network should have unique address settings (telephone
numbers) to facilitate proper signaling.
Rear Panel LED
The rear panel of the IDU has a single LED that reflects the summary state of the radio, exactly copying the
status bar on the Web browser interface (see “Front Panel LEDs” on page 73). The LED is red when any alarm
is active or the front panel LED is red, yellow when any front panel LED is yellow and none are red, and green if
all front panel LEDs are green or off.
