Site Orientation
Poles and cross member must be in an E-W orientation this will allow for the following:
Wind vane and anemometer –North Facing
Black globe thermometer –North Facing
Rain gauge, air temperature, humidity and solar radiation (unobstructed) sensors –South
Facing
Solar panel –North Facing
Enclosure –South Facing
Construction Order:
Orient the oppositions of the steel posts to E-W
The steel posts must be as close as possible to 1150mm apart (tip to tip)
Embed steel posts with only 1m remaining out of the ground.
Attach the 2m posts to the steel post using two hose clamps provided –one at 100mm from
the ground and the other at the top of the steel post (~1m above the ground) ensuring it is
well below the drilled hole.
Align the lowest holes in the poles toward each other to allow for wiring to pass into the
cross member.
Mount the Davis and Environdata sensors to the WS Pole Left and run the wind cable under
the rain gauge then into Davis control box. Connect at the labelled location. The Console
cable must be also be connected then the foam plug refitted inside the Davis control box.
Tools required 11mm spanner, 10mm spanner and 10mm socket.
Pass the console (Davis) and Black globe cables through the rubber grommets and the
appropriate drilled holes leaving them exiting the pole at the cross member position. Don’t
forget to thread and fit another grommet to sit inside the cross member.
Cable tie if necessary.
Fit out the solar panel with two brackets and cross member using the 6 off M8 x 20mm bolts
provided. Attach the bird deterrent to the top of the panel using two 4mm tek screws
provided. Mount the panel together with the antenna bracket (facing backwards) on the DN
Pole Right. See photos. Tools required –two 13mm spanners and a 13mm socket
Mount the enclosure about 50mm higher than the cable exit hole (on the southern side of
the pole). Tools required 13mm socket.
Mount the antenna (either 4G or Satellite) and pass both the antenna and solar panel cable
down through the top of the pole to the exit hole under the enclosure. The GPS and 4G
antenna are different sizes and t is useful to have a 14mm spanner and 17mm spanner
available or carry a shifting spanner.
Pass the solar panel and antenna cables down through the pole and exit underneath the
enclosure. You may need to use a cable draw to assist with this.
If necessary, cable tie the solar panel cable to its bracket and place another cable tie around
it and the antenna cable to secure their position in the top of the pole.
Draw the weather station cables through the 2” cross member and pass them into the DN
pole then up to the enclosure exit. Again you will likely need to use a cable draw to assist.
Make sure you fit a rubber grommet to the cables once they exit the cross member so that it
can be fitted into the pole.
Fit the cross member using the galvanised T Clamps provided.
You should now be ready to wire the cable into the DN200.

DN200 enclosure cabling and wiring
When fitting wiring or replacing modules always ensure the unit is off (power switch in OFF position)
and you have removed the 2A fuses.
Fit the cable glands into the appropriate holes in the bottom of the box.
If this is a satellite system then dismantle the GPS antenna and fit it through the top of the
enclosure. There will be one metal washer and one nut to secure the panel mount connector. Leave
the spacer washer and sealing washer in the inside. Place the black rubber over the SMA connector
and then screw the antenna down until it seals.
Move to the DN200 and press on all the modules on the front board to make sure they are firmly
seated. Some movement may occur during transport.
Pass the Davis cable through the left hand 16mm gland. Plug the Davis weather station into the
black comms module in port 1 via the RJ11 connector. Make sure the RJ11 connector is firmly
seated.

DN200 Weatherstation Installation Manual Revision B Page 6
Pass the grey black globe through the left hand 12mm gland. Only 2 ferrules can pass at the same
time so work the third though later using a pair of long nose pliers to assist.
Connect the black globe wiring to Port 2 as follows:
Red to Pin 1, Blue to Pin 3 and Green to Pin 4.
Pass the antenna cable through the 16mm cable gland on the right and attach it to the SMA panel
mount connection inside the enclosure. Do this up firmly by hand and then tighten with and 8mm
spanner about ¼ of a turn.
Pass the solar panel cable through the 12mm gland on the right hand side of the enclosure. For a
Satellite system wire this into the white twin terminal on the end of the red and blace solar panel
cable. Make sure you wire as follows:
BROWN to RED (positive)
BLUE to BLACK (negative)

DN200 Weatherstation Installation Manual Revision B Page 7
Place the battery and zip tie it in with the cable tie provided. Attached the battery connections
making sure red in positive and black is negative.
If you reverse the polarity for either the solar panel or battery you will blow the respective 2A fuse.
Spares have not been provided however replacements are available from most service stations or
auto parts shops.
Commissioning:
Replace the fuses.
Turn on the DN200 in the following manner. Switch the power slider to ON (down) then press and
hold the Start button for about 2 seconds.
Monitor the light activity. You should see a series of flashes then lights will generally remain
constant for 1 minute. After that time the status light will only flash every 5 seconds.
Connect to the DNB200 using a USB Mini cable. Load the DN Configuration Tool program and
connect to the Node.
Check that the unit is collecting readings using the Reading tab > Last Reading or New Reading.
Check the Davis PCB and make sure there is a flashing LED in the top of the board. This indicates it is
powered and running.
If you notice errors in the Davis readings check that all RJ11 connections are firmly seated.
Review the readings and assess if these are within the expected ranges.
The next step is to check that readings are loading onto the server. This may have to be reviewed at
a location that has internet access.
Readings will only be pushed or collected for every 15 minute interval.
This will happen within 2 minutes of 00, 15, 30 and 45 for 4G systems.
For Satellite systems this may take several hours before readings appear. It will depend on satellite
availability. Satellite messages are stored on the Swarm module and are sent as soon as a
connection is available.
Contact Rimik for assistance if necessary.

DN200 Status LEDs
The status LEDs on the DN200 fall into two categories, ones that are always active and ones that are
only active on-demand. Always active LEDs always reflect the relevant system status. On-demand
status LEDs will only reflect the relevant system status at startup or when the START/CHECK button
has been pressed. Pressing the START/CHECK button will activate the on-demand status LEDs for one
minute after the button is released. This makes it easy to view the LEDs when necessary while saving
power when the system is unattended.
The status LEDs are split between the two types as follows:
Always on LEDs:
SYSTEM - STATUS
TELEM - STATUS
On-demand LEDs:
SYSTEM - CHARGE
SYSTEM - BATT
TELEM –SIGNAL
SYSTEM –STATUS
Will flash once every 5s in normal operation.

Telemetry Checks specific to 4G and Satellite carriers
4G
The TELEM STATUS light indicates the connection status of the modem. A solid light means that the
modem is on but not connected, while a flashing light indicates that the modem is on and
connected. It may take a few minutes for the modem to connect after powering on.
The TELEM SIGNAL light indicates the signal strength using three levels. Red = poor, orange =
average, green = good. To save power the TELEM SIGNAL light turns off after one minute. Press the
START/CHECK button to turn it back on.
Satellite
The TELEM STATUS light will always be on solid for a Swarm satellite modem when it is powered on.
The TELEM SIGNAL light will flash green when the Swarm module transmits, but it is unlikely that
you will ever see this in practice due to the speed of transmission.
The Swarm modem has three status LEDs on its right-hand side near the antenna connections:
Green
On solid at startup.
Flashes once every 5s while the modem is powered on.
Red
On solid at startup.
Flashes while searching for a GPS fix.
Off during normal operation.
Blue
Flashes when the modem hears from a satellite passing overhead.
The Swarm modem is unable to transmit until it has a GPS fix. Check that the red LED on the Swarm
modem stops flashing within a few minutes of powering on. If the red LED is still flashing after a few
minutes there may be an issue with the GPS antenna and connections.
To check the Swarm modem signal strength.

DN200 Weatherstation Installation Manual Revision B Page 11
Connect to the DN200 using a USB Mini cable.
Load the DN Configuration Tool program and connect to the Node.
Go to the Reading tab and click on New Reading.
Check the Swarm Background RSSI value. It should be less than (more negative than) -90dB
for reliable operation. If the background RSSI is around -110dB there may be an antenna
connection issue. See below.
Check the Swarm RX RSSI value. This represents the signal strength of the last satellite that
the modem heard from and should be non-zero. Ideally this is equal to or greater than the
background RSSI reading. If it is zero then the modem has not yet heard from any satellites.
If the Swarm modem does not appear to be transmitting messages. E.g. no data is received by the
Swarm or Rimik servers even after a known satellite pass it may be necessary to check the antenna
connections.
To check the satellite antenna connection:
First disconnect the satellite antenna from the top of the pole. (Do not disconnect the
antenna cable from the modem end.)
Load the DN Configuration Tool program and connect to the Node. Go to the Reading tab.
Wait at least 1 minute from when you disconnected the antenna and click on New Reading.
The Swarm Background RSSI should be close to -110dB.
Reconnect the antenna.
Wait at least 1 minute from when you reconnected the antenna and click on New Reading.
The Swarm Background RSSI should have increased noticeably.
Place your hand around the antenna and hold it for at least 1 minute.
Click on New Reading. The Swarm Background RSSI should have changed noticeably. It may
have increased or decreased depending on the circumstances.
If no significant variation in Swarm Background RSSI was observed with the following tests there may
be an antenna connection problem. Inspect all antenna cables and connections to ensure nothing is
loose or damaged. You may wish to disconnect the cabling and check continuity with a multimeter.
Check and ensure that the satellite antenna is connected to the antenna port on the Swarm modem
labelled VHF.
