RF NETWORK DETAILS
Network ID
This parameter sets the network ID of this base station node and its remote / repeater stations in the
network. The entry is four hexadecimal chars (not case sensitive).
The default setting is CAFE.
Base Station ID
This parameter identifies the base station. All radios operating to the base station in the same network
must use the same Base Station ID setting.
It is especially important to set different values for each network when two or more networks using the
same frequencies are operating with some overlapping coverage. The entry is an integer from 1 to 8.
Network Radius
This parameter sets the maximum number of hops in this network e.g. in a network with base station,
repeater and remotes communicating via the repeater, the Network Radius should be set to 2. If the
Network Radius is set to 2, a message from that node will only pass 2 hops before it is blocked.
The default setting is 1.
When base station is configured as a ‘Base-Repeater’ (used for remote peer to peer operation via the base
station), the use of Network Radius does not change and works the same as if it were a Base Station i.e.
the Network Radius is always the number of hops from the base station to the most distant remote in the
network.
All stations in the network should be set to the same value.
Network Repeaters Proximity
This parameter is set in base stations, remote stations and repeater stations to indicate the proximity of
repeaters in the network when the Network Radius is set to greater than 1.
Option
Function
Single Repeater Only
Use when there is only one repeater in the network.
Overlapping Coverage
Use for multiple one hop repeaters where the remote station can
see more than one repeater or repeaters can see each other.
The communication protocol is slower because each repeater is
addressed individually and in-turn.
Separated Coverage
Use for multiple one hop repeaters where the remote station can
only see one repeater and the repeaters can’t see each other.
This option provides better network downlink performance than
the Overlapping Coverage option.
However, if the repeaters can see each other, the resultant
collisions will cause corruptions and dramatically reduce network
downlink performance.
