Overview
The Brizo-X Directional Wave Height Sensor utilizes Global Navigation Satellite System (GNSS) to
measure wave statistics. Since the Brizo-X uses GNSS to calculate its heading, no calibration is
required.
The sensor is housed in a robust enclosure for rough environments and to prevent water ingress.
The sensor runs autonomously and can record data to SD cards, as well as output over RS-232 or
send messages over the Iridium network.
Pin-out Diagrams
The Brizo-X has only one available connection for all physical inputs and outputs. Below are the

Telemetry Configurations
Iridium Transceiver
The Brizo-X has the option to be equipped with an Iridium satellite transceiver at the factory if
requested. The transceiver can be used to transmit SBD (Short Burst Data) packets for coefficient
transmission. Iridium has global coverage and is suitable for any location. An Iridium data plan is
required to use these features. Contact Xeos Technologies for a plan suited to your needs.
For more details on Iridium, see Appendix C: Iridium Service.
GNSS
The Brizo-X uses GNSS to gather wave data to calculate parameters for wave statistics and
coefficients at programmed intervals. It is a critical component of the Brizo-X of any model.
Local Data Output
Diagnostics
Serial port 1 is the default port for diagnostic output of the Brizo-X. As such, this port displays
operational activity, as well as allows for configuration of the device.
Serial Data
Serial port 2 is used for output of wave height data statistics to connected peripheral devices.
The Brizo will first acquire a GNSS signal to calculate parameters before outputting results.
The default port settings for serial ports are as follows:
Baud Rate
115.2k
Parity
None
Data Bits
8
Stop Bits
1
SDI-12 Data
A substitute for Serial port 2, all SDI-12 communications are transmitted in ASCII, but
operationally outputs the same data as other communication methods.
Port settings for serial ports are as follows:
Baud Rate
1200
Parity
Even
Data Bits
7
Stop Bits

SD Cards
Onboard the Brizo-X is one 4GB SD card raw GNSS velocity data. The raw data can be used for
post-processing by the user to further analyze the wave data for spectra, etc.

5
Raw GNSS velocity cannot be sent over the air or serial. When the SD card is 90% full, the device
will delete the oldest 10% of data stored.
Devices manufactured with Ethernet capability can download data from these cards without
disassembly. Otherwise, returning the device to Xeos for data extraction is the best course of
action, if needed.

Device Preparation
Iridium
Iridium Subscription
If the Brizo-X in application is equipped with an Iridium modem, the IMEI of the device must be
provisioned to send data on an Iridium data plan. If the modem is not activated, messages
transmitted will not be received at any location.
For more details on Iridium, see Appendix C: Iridium Service.
Iridium SIM Card
The Iridium SIM card (if Iridium is included) is installed at the factory and should not be changed
or modified by the user. If necessary, the device can be sent back to the factory for repairs
relating to Iridium telemetry issues.
Data Output
If wave height statistic data is to be output to a peripheral device, proper interfacing should be
tested, both with regards to the Brizo-X’s port functionality via command, and to any interfacing
device such as a data logger.
Orientation
The bottom plate of the Brizo-X designed to streamline the mounting process, whether that be
plate-mounted or pole-mounted. It is crucial the top of the Brizo-X is facing the sky directly, flat,
with as much overhead view of the sky as possible. If obstruction is unavoidable, effort should be
made to have as little as possible. This will allow for a stronger connection to the satellites and in
turn, more accurate and consistent wave height results.

7
Power
The Brizo-X requires power supply capable of sourcing three amp surge currents at 12 V. This
can be reduced to one amp if no Iridium modem is present.
The MCBH connector on the Brizo-X is the only external connection present. The mating
connector on the end of the cable provided with the device supplies power and serial
communication (if needed). It is a standard Subconn connection with female bulkhead, male
inline connector and locking sleeve.
Prior to making the connection, inspect both connectors and remove any dirt, water or other
debris. If either connector is damaged, contact Xeos Technologies.
The majority of units in the field will be powered by battery and solar panel. It is recommended
to utilize a charge controller for the battery that is equipped with a low voltage disconnect, which
will increase the lifespan of the battery.

Installation of the Brizo-X
Mounting the device
The Brizo-X is housed in a waterproof enclosure. As a consequence, all components of operation
except for input power are fully integrated.
For the performance of the sensor it is important for the GNSS antenna to have a clear view of
the sky. The GNSS antenna is placed under the risen circle on top of the enclosure.
It is recommended to install the Brizo-X flat, at the highest point on a buoy, or closest to the top
with reasonable space to mount.
Due to the nature of GNSS wave height measurements, the Brizo does not have to be at the
center of gravity of the buoy, but it is favorable to have it as close the center z-axis as possible.
Some reasonable offset (up to 18 inches) away from the center z-axis is acceptable.
Depending on the application, varying mounting methods can be explored. The Brizo-X’s
enclosure has features that lend themselves to mounting to a baseplate, or pole-mounting.
It is crucial to mount the Brizo-X before connecting power to avoid damage to the Brizo-X or its
cabling.
Confirming Device Operation
Confirm Power to the Unit
Plugging the power connector into the unit, the LEDs on top of the unit will flash. These can be
difficult to see in daylight conditions currently. If the Serial 1 port is accessed by a device capable
of reading its output, diagnostics will also immediately be visible.
Confirming Iridium Operation
A startup message will be sent upon power-up of the device to confirm power to the unit and
Iridium satellite connection. This message will not include any wave statistics or Status of Health
data.
