SN400 Installation Guide
and
R9 Online Portal User Guide
contains information on
specific sensors and associated port numbers. Also, when onboarding your system on
the R9 web portal, you will be guided through the process of inserting wired sensors into
the SN400. The onboarding process is customized for specific sensing applications.
The sensor node device is typically mounted to equipment, and then cabled sensors are
applied to specific areas for sensing. For example, a node device is attached externally to
a refrigerator, and then a cabled temperature sensor is routed inside the refrigerator to
measure temperature.
For simple installations,
the SN400 node can be installed inside a room, or
refrigerator/freezer, without cabling
for the measurement of temperature. If installed
inside a refrigerator/freezer, wireless range may be diminished (typically by one third to
one half), but should be adequate for connection to a nearby gateway device.
The SN400 sensor node requires an external DC power source, or two AAA alkaline
batteries to operate. The sensor node does not have a power switch. When power is
applied by DC jack or insertion of batteries, the device will power on and automatically
begin to broadcast information to allow synchronization with, and connection to a nearby
gateway that is also powered on. Note that in order to pair with (connect to) a gateway
device, all sensor node devices should be setup first, using the online R9 portal. Refer to
the
R9 Online Portal User Guide
for information on how to onboard and configure the
gateway and sensor nodes in your monitoring system.
