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.
