NW(Network Watchdog Timeout)
Set the network watchdog timeout used to ensure that a coordinator is active on the network (for
example, a keep alive message).
If NW is set > 0, the router monitors communication from the coordinator (or data collector) and
leaves the network if it cannot communicate with the coordinator for 3 NW periods. Alternatively, If
DC bit 5 is set, the router will not leave the network but will instead attempt to rejoin the coordinator.
The device resets the timer each time it receives or sends data to a coordinator, or if it receives a
many-to-one broadcast.
Parameter range
0 - 0x64FF [x 1 minute](up to approximately 18 days)
Default
0 (disabled)
JV (Coordinator Join Verification)
Used during join and rejoin attempts to determine if a coordinator is present on the target network.
If JV = 1, a router or end device verifies the coordinator is on its operating channel when joining or
coming up from a power cycle. If a coordinator is not detected, the router or end device leaves its
current channel and attempts to join a new PAN. If JV = 0, the router or end device continues
operating on its current channel even if a coordinator is not detected.
Parameter range
0 - 1
Value Description
0 No coordinator verification
1 Coordinator verification enabled
Default
0
JN (Join Notification)
Broadcast Join Notification upon successful join attempt.
If enabled, the device transmits a broadcast node identification packet on power up and when joining.
This action blinks the Associate LED rapidly on all devices that receive the transmission, and sends an
API frame out the serial port of API devices.
Digi recommends you disable this feature for large networks to prevent excessive broadcasts.
Parameter range
0 - 1
