Watch the mote LCD during the process of joining the
network.
Note:
If the mote cannot find the network or has
trouble remaining connected during this process, make
sure the mote is in a vertical, upright position and
within range of the station.
Repeat these steps to add other motes. Press the
Search button on the station when finished adding
motes.

Connect analog sensors or relay devices.
If you are using the optional analog sensor module or relay
module, follow the steps in this section to connect the
sensors or devices. Be sure to feed any cables or wires
through the smaller cable access opening shown below.
Important:
If you will be installing the weatherproof rubber
cable channel in the cable access opening as described in
Deploying and Mounting the Station
, the cable diameter for
analog sensors or relay devices must be 4.0 mm (0.156 in.) to fit
through one of the five smaller holes or 6.4 mm (0.25 in.) to fit
through one of the five larger holes. If the cable diameter is too
small, build up the diameter using heat shrink. If the cable is
too big, splice on another cable with a smaller diameter to fit
through the hole.
To connect analog sensors:
You can connect a two- or three-wire sensor or transducer
to one of the four terminals in the analog module.
a.
Loosen the screw for each pin on the screw terminal.
b.
Feed the wire through the smaller of the two cable
access openings.
c.
Insert the appropriate wire into the screw terminal (see
the pinout table below). The wire should be trimmed to
expose 0.25 inches ±0.04 inches of bare wire.
d.
Tighten the screw.

To connect relay devices:
You can connect up to three devices to the relay module.
The relays are only for low power switching. To switch to
higher power, use an appropriately rated relay and use the
station relay to switch the external relay on or off.
a.
Loosen the screw for each pin on the screw terminal.
b.
Feed the wire through the smaller of the two cable
access openings.
c.
Insert the appropriate wire into the screw terminal (pins
1 and 2 are interchangeable, pin 3 is optional; see the
pinout table).
d.
Tighten the screw.

Connect to HOBOlink.
Use the Select button to return to the main LCD screen that
shows all sensors and modules and then press the Connect
button (the cloud icon should be visible as shown in the
following example). This is necessary for HOBOlink to
identify the newly added sensors (it does not start logging;
this will be done later in this procedure). Note that analog
sensors will not be listed in the channels count on the LCD
until they are configured in HOBOlink in the next step.
Feed analog sensor
and relay cables
through this opening
to connect them to
the optional modules
This signal strength icon
blinks while searching for
a network.
Once a network is found,
the icon will stop flashing
and the bars will cycle from
left to right.
c.
d.
This network connection “x”
icon blinks while the mote
completes the registration
process, which may take up
to five minutes.
Once the mote has finished
joining the network, the “x”
icon is removed and the
channel count on the station
LCD increases by the number
of measurement channels for
the mote plus the battery.
