Neon ( NRT) Display Unit
The Neon Display Unit is built into some models of NRT/NRM and is also available as a
standalone unit to be used as a field setup tool. There are info and signal strength
indicator/buttons and the facility to initialise an NRT/NRM in the field.
The NRT Display unit allows the user to obtain limited status information from the
NRT/NMM/NRM by pressing the appropriate buttons, for example pushing the NRT
Display Unit Info Button should display server information for approximately 10 seconds
and then turn off.
To conserve battery power, the display only is visible for approx 10 seconds, after which
time the button need to be pressed again to re display the information.
Each button initiates a task for NRT display unit to start a task of interrogating the
NRT/NMM/NRM. The task of interrogation of the NRT/NMM/NRM starts and completes
after the information is obtained and displayed. Hence the message “ending task” will be
displayed from time to time, indicating the interrogation is complete and the information is
available to view.
One of the key uses for the NRT Display unit is to automate and assist with / automate the
initialization process in the field, especially for satellite based units.
3.4.1
NRT Display Unit- Satellite Initialization
Hold down Initialize button on the NRT Display unit and observe the count down to zero
and the display “initializing please wait” This requirement to hold the button down is to
make sure accidental initializations do not occur. The system will then attempt to acquire a
Satellite for the initialization process. Depending on the time of day, the location and the
field of view of the sky this process can take 15 to 60 minutes, but typically is less than 30
minutes.
It will display the following messages while attempting to acquire satellite
Retry Attempts
………
This is the number of satellite communication attempts.
Service Available NO
NO Satellites in View.
Waiting Initialization
attempting 50
This is the number of seconds before the next retry.
OR
Retry Attempts
………
This is the total number of satellite communication
attempts before the initialization was successful.
Initialized OK
Once initialization has occurred, the unit can then be closed
The LCD has 60 retry attempts, to ensure there are satellites available for initialization.
