Event History
The Event History tab displays a log of internal events, such as gateway restarts, logins, firmware updates
and other general events.
Provision
The Provision settings allow configuration of the Network ID, Join Key, local area network (LAN) settings
as well as the Tag for the NG Series Industrial Wireless Gateway.
Logging
The Logging settings change the System Manager level of detail which is recorded in logs for debugging
purposes.
Operational Settings
The Operational Settings contain channel enabling/disabling, configuration of number of router and IO
nodes allowed to join the 1
st
layer of the mesh (i.e. the 1
st
hop from the access point). The number of
Routers and IOs allowed to connect to routers in further hop layers is also configurable. The max number
of layers (hops) is also configurable. More routers result in higher consumption. The recommend
maximum number of routers is no more than 30% of all field devices.
