Using Auto Assign Selected
Figure 58
There are certain requirements that need to be fulfilled before the Auto Assign Selected can be
utilized properly.
o Tick the Auto Assign Selected box on.
o Select the NRU from the list, that is at the station you are approaching on the line.
o NuSite has to have received a current location update from the NuSite device.
o Selected NRU must be deployed and not already assigned in the NuSite database.
o Nearest receiver point is not assigned in the NuSite database.
In order for the Auto Assign Selected option to work consistently, the accuracy of the NuSite
device GPS has to be taken into account as well as the receiver point spacing.
o Auto Assignment will only happen when the NuSite device is within ½ the distance of
the receiver spacing to the receiver point that the NRU is being Auto Assigned to.
Receiver spacing is 25 meters, the NuSite device position must be within <=12.4
meters of the receiver point.
If a tight receiver spacing of 5 meters is being used and the NuSite device GPS
accuracy is 1-5 meters, then Auto Assign Selected may not operate efficiently.
An accurate external GPS would need to be used in this case or only use manual
assignment.
There are two options for AutoAssign
o Assign station within first 30 seconds after NRU is deployed
o Assign station to NRU after it has passed self-tests and started recording
Immediate AutoAssign
1. Use the NuSite Map to navigate to the unassigned receiver station, making sure the external
GPS accuracy is good.
2. Use the MDT to create a hole for the NRU, bump the NRU, and insert into the hole.
3. NuSite should automatically assign the station to the NRU after the green LEDs have flashed
5 times on the NRU.
4. Move to the next station after confirming station assignment is correct.
