WNC Software Configuration
The WNC unit can be configured by using a hyperterminal window on a laptop computer’s serial connection. Once DC
power is applied to the WNC unit, it executes a software boot sequence which ends at the WNC main menu screen.
From this menu, the WNC can change Ethernet or Serial settings, set health alerts, access diagnostics, upgrade the WNC
firmware, and also control the embedded tag settings.
GPS Master Station
The vast majority of new units will require WhereNet to provide DGPS for the CHE location reporting. This will be
accomplished by the use of a GPS reference receiver or “master station”, whose function is to provide GPS correction
data. The baseline architecture will be inverse DGPS, but the system will be able to support forward DGPS as well.
The GPS Master Station is installed on-site at a location that presents a clear view of the sky for optimum reception of the
GPS satellites. It is envisioned that this will generally be possible by placing the GPS Master Station on the roof-top of a
building in the facility.
