The Radio Network
A Sontay
®
SonNet radio system is comprised of a receiver, battery powered sensors, RF-‐IOMs and
permanently powered routers.
Routers, though permanently powered, can also have sensing elements, accomplishing both router and
sensors functions. Routers, RF-‐IOMs and sensors can either communicate directly with the receiver or
via
other routers and RF-‐IOMs. RF-‐IOMs and routers are required to be permanently powered as they need to
stay “awake” at all times to allow signals from “child” nodes to be forwarded to their “parent” nodes.
Battery powered sensors only “wake” for very short periods to send data.
The receiver can support a
maximum
of 16
directly
connected “child” devices, of which a maximum of 12
can be battery powered EDs (End Devices), plus up to 4 routers or RF-‐IOMs. If no EDs are directly
connected, the receiver can accept up to 16 directly connected routers or RF-‐IOMs.
RF-‐IOMs and routers can support a
maximum
of 16 directly connected “child” devices, of which a maximum
of 8 can be EDs, plus up to 8 routers. If no EDs are directly connected, the router or RF-‐IOM can accept up
to 16 directly connected routers or RF-‐IOMs.
There can be a maximum
depth of 8 layers of routers
in a network and a
maximum of 40 nodes per
network with the
RF-‐RXS-‐B
receivers.
