7.2.4 Waypoints
The i50 can store up to 200 circular waypoints in non-volatile memory. There are two kinds of
waypoints: standard and RF zone.
Standard waypoints are used to generate alerts whenever the unit enters or leaves these areas.
Each standard waypoint can also be configured so that position reports are disabled while the unit is
at that location.
RF zone waypoints are used in three cases:
1) When WAN mode is enabled under Kenwood radio settings, the i50 will automatically select
the radio zone and channel when sending data, based on the current RF data zone. When the
Auto-Roam mode is enabled under Kenwood radio settings, the i50 will also control the current
voice channel, based on the current RF voice zone.
2) When a Relm radio is enabled, the i50 controls the
radio’s zone and channel assignment
based on the current RF zone (in the case voice and data zones are treated the same).
3) When any output pin is programmed for Channel Selection mode, the i50 will set the output
states to match the current RF zone (voice or data are treated the same). In this case, all
channel selection outputs will be inactive when the i50 is outside all RF zones.
The i50 Programmer has a Waypoints tab where the data can be retrieved from and sent to the
device, or loaded from /saved to disk.
ID:
Waypoint ID (0-8191) that will be displayed in the alert message.
Lat/long:
Position at centre of waypoint.
Inner Radius:
Device must enter this area to trigger an enter event.
Outer Radius:
Device must leave this area to trigger an exit event. Setting this value larger
than the inner radius will reduce the number of false events received when a
unit spends time near the edge of a waypoint.
Zone:
Radio zone (1-63) to be selected when i50 is inside the RF zone.
Channel:
Radio channel (1-250) for this zone.
Range:
The i50 will only use this zone if it is within the range specified. If it is outside
all data zones in WAN mode, it will stop sending data. If the i50 is within
multiple RF zones, it will select the closest one.
Note: when position reports are disabled due to a waypoint setting, the i50 will also disable its
periodic wakeup reports. It will continue to wake up periodically to confirm whether it is still inside the
waypoint, but will not transmit.
