3.1 ANTENNA BASICS
Before deciding on a location to install your D2O unit it is important to
understand how the D2O operates.
The D2O uses electromagnetic radio waves to communicate with the
individual satellites in a nano-satellite constellation. Transmission and
reception of these waves is facilitated by the D2O’s antennas.
The D2O knows when these orbiting satellites will be transiting through a
visible section of sky and transmits messages during this window.
The vertical orientation of the D2O’s antennas means that it has the strongest
transmission and reception abilities in a range perpendicular to the Antenna,
emanating in a radial pattern. When a satellite passes through the sky
between the horizon, and up to approximately 75° from the horizon the
D2O has the greatest opportunity for a successful transmission or reception.
Satellite passes below 20° above the horizon have a lower probability of
transmission.
Directly above the Antenna, between 75° and 90° (straight upward), the
transmission and reception abilities of the Antenna are poor.

SIGNAL STRENGTH+ -
Most satellite passes will occur across a partial section of sky. This is due to
the orbital pattern of the satellites and their relationship to the D2O’s position
on earth.
Having a clear line of sight to as much of the sky as possible, and in all
directions, will minimise the risk of missed transmission opportunities.

The lighter Blue arrow shows a satellite pass that goes directly overhead, allowing for a long transmission window with a short break while
the satellite is directly overhead. The darker Grey arrow indicates a low satellite pass that only appears in the sky briefly, at a few degrees
above the horizon. The D2O will experience a mixture of these types of passes.
3.2 SITE SELECTION
A site should be selected where the D2O unit can see the most sky possible.
Where practical the D2O should always be the highest mounted object on top
of a mounting post. Avoid placing the D2O in the following locations:
• In close proximity to buildings, fences, poles, or other structures
• Under or near tall trees or dense foliage
• At the bottom of deep canyons or valleys
• Underneath or in close proximity to solar panels, weather stations, or any
other type of equipment that may share a mounting post/mast with the
D2O
• In a mounted position that is at risk of flooding/submersion
• In close proximity to sources of RF interference such as high voltage power
lines, mobile phone towers or radio towers
Placing the D2O unit in any of the above situations may restrict, or prohibit,
successful transmissions.
Ideally the D2O should have a clear view of the sky in all directions from 10°
above the horizon.

An improved site. The distance to the building has increased and an area with lower surrounding foliage has been selected. To further
maximise transmission opportunities the D2O has been placed on a taller mast allowing for a wider view of the sky. Now the overlap of the
unobstructed angles (dark segments) has increased to cover almost all of the ideal angles (lighter segments).

3.3 MINIMUM CLEARANCE
Irrespective of the mounting type or scenario, the D2O must have a minimum
clearance to the nearest object to avoid Radio Frequency (RF) interference
and adverse Antenna influence.
With the exception of the mounting device itself (post, mast etc.), there should
be no other surfaces or objects within 150mm below the base of the D2O unit
and 500mm radially from the centre of the unit as per the diagram.

As a first step the Antenna must be installed on the D2O unit before it will
function.
The Antenna is then attached by screwing it on the exposed Antenna Base
thread on the top of the D2O unit. It should be tightened until the Antenna
contacts the D2O Unit. Do not over-tighten the Antenna as irreparable
damage may occur.

to avoid accidental eye contact with the Antenna tip.
3.4 PRE-ASSEMBLY
Tighten Grub Screw.
Fill head with epoxy
for tamper protection
Tighten the Antenna’s M4 securing Grub Screw until it bites into the Antenna
Base thread and prevents the Antenna from being unscrewed by hand. For
scenarios where tamper prevention or evidence is require then the Grub Screw
head can be epoxy filled.

10 - D2O FL1 Product Manual
The D2O supports direct installation to a cylindrical post. The mounting
socket on the D2O can accommodate a post with:
• Outer diameter 32mm - 34.5mm
• Internal diameter >26mm
The preferred solution for direct mounting of the D2O is the use of a Nominal
Pipe Size (NPS) steel post with a Diameter Nominal (DN) 25mm or 1 Inch,
as specified in the Australian/New Zealand standard AS/NZS1163 or the
American Standard ASTM A53M.
25mm (DN) NPS is specified as having an outside diameter of 33.4 - 34mm and
is commonly available in hardware stores and from steel suppliers, oen sold
as fence posts.
Suitably secured galvanised or stainless steel post should be used to ensure
weather resistance and durability. Providing a path for any water to drain from
within the post will reduce corrosion potential and extend the installation life.
As well as ensuring a suitable height for transmission capabilities, as per the
Site Selection section, the height of the post should also correspond to the
risk of damage or interference to the D2O. For example if used in an area with
livestock the device should be higher than the livestock could reach. If prone
to vandalism the D2O should be high enough to deter interference and may
require additional protection mechanisms.
The D2O is capable of being mounted in several ways. In all mounting
scenarios it is recommended that the supplied 1.5 meter 8-Pin M12 Interface
Cable is threaded through the mounting device (e.g. a post), emerging only at
the point of connection to a device or junction box. This is to decrease the risk
of damage to the 8-Pin M12 Interface Cable from sources such as:
• Bird, livestock or other animal damage or abrasion
• Falling branches or foliage
• Premature cable deterioration from ultraviolet light and weathering
• Snag risks
As such it is important to prepare the mounting device and cable before
installing the D2O.
If applicable, an appropriately sized hole should be drilled where the cable
will exit the mounting device and the cable threaded through the post and
hole prior to attaching the D2O. Ensure the hole is clean, de-burred and will
not damage the cable. Consider the use of a rubber grommet on the hole
edge to increase protection.
The 8-Pin M12 Interface Cable should then be attached and fastened to
the D2O unit via the 8-Pin M12 Connector, ready for final mounting and
commissioning.
3.5 D2O INTERFACE CABLE ATTACHMENT
3.6 POST MOUNTING

D2O FL1 Product Manual - 11
Antenna mounts and masts are commonly available with a 32mm outer
diameter post making them an acceptable mounting solution.
Several antenna mast kits, including guyed options, are capable of extending
several meters into the air and may be a preferred solution to increase
transmission capabilities in areas where the D2O is surrounded by tall objects.
IMPORTANT NOTE:
If installing the D2O at a height that cannot be safely
reached once installed, such as a tall mast, ensure the D2O
is switched on and commissioned prior to mounting as these
steps require physical access to the device.
Ensure the post or mount is engaged all the way to the bottom of the D2O
mounting socket. The D2O is supplied with a Hex Head Grub Screw to fasten
the device to its mount. Use a 2.5mm Allen key or other 2.5mm Hex drive to
fasten the grub screw. The screw should only be tightened enough to stop
easy rotation or removal of the device.
IMPORTANT NOTE:
Do not over-tighten the grub screw. It is possible to
permanently damage the D2O’s plastic enclosure by over-
tightening the grub screw to the mount.
For increased mounting strength on a 34-34.5mm post, pre-drill a hole in the
post for the grub screw to pass through. The hole centre should be drilled at
14mm from the top of the mount, in the desired direction. The use of a 5.5mm
drill is recommended.
If using a post with a diameter <34mm, pre-drill an indentation/recess into the
post at the same location. In <34mm diameter pipe a complete hole will not
provide the securing force required and the D2O will have a loose fit.

5.1 INTRODUCTION
Before the D2O can perform its normal operation it must be programmed with
the desired operating parameters.
Programming occurs via a serial interface, using a plaintext protocol that can
be entered by either human or automated system input. A Serial Terminal
soware application (such as Tera Term), running on a Computer, is required
in order to send human entered input commands via a Command Line
Interface (CLI) to the D2O.
Once a connection is established, the CLI provides the following setup
features:
• Control of the D2O Digital Power Switch
• Set device acquisition and system parameters
• Generate a Commissioning Report to confirm current settings
When setting up a D2O for the first time the steps shown in the following
sections should be sequentially followed to ensure the D2O will be correctly
setup and perform its normal operation.
Before commencing any programming or commissioning tasks the following
prerequisite tasks must be completed:
• A 4-Pin M12 to USB-A Cable must be available for connection between the
D2O and a USB port of the Computer, without extension. Ensure the USB
Port is capable of providing at least a 500mA supply
• Ensure GPS satellite signals are available by moving outdoors or close to a
window (required to obtain date, time and location settings of the D2O)
• Serial Terminal soware is installed on the Computer
5.2 PRE-PROGRAMMING CHECKLIST
TO COMPUTER
5.3 CONNECTING TO A COMPUTER
Interfacing to the D2O can occur once the unit has been connected via the
4-Pin M12 to USB-A Cable, to the Computer.
Remove the protective Dust Cap from the 4-Pin M12 Connector on the
bottom of the D2O, and store safely for later replacement. Connect the 4-Pin
M12 to USB-A Cable in-between the D2O and a Computer, ensure that the
Computer’s USB Port is capable of providing at least a 500mA supply.
The D2O unit is now being powered by the USB connection and will
commence its start-up sequence.

D2O FL1 Product Manual - 15
Once powered the expected start-up sequence for the D2O is as follows:
• The unit will power up and within 2-5 seconds a light within the Battery
Switch should flash a green light twice
• The D2O now acquires the GPS location, time and date settings which can
take up to 90 seconds
• Next the start-up sampling configuration and system status information is
