== Introduction ==

This document describes the hardware components of the OWL^TM^ system. It is written to
give an overview of the system on the highest level. It shows the components,
connections between the components, connections between the OWL^TM^ and it's platform
(ship/buoy/rig) and specifications.

Detailed [[attachment:'Ocean_Visuals_OWL_datasheet.pdf'|datasheet]] OWL^TM^ Shipborne and
OWL MAP^TM^ is attached.\\


Description of the measurement process is described in [[PhysicsOfOWL|Physics of OWL]].

The system has two components:
* Junction box that holds circuit breakers, power-line communication modem and server.
The junction box needs a LAN cable and a regular AC current from mains.
* Measurement device enclosed in a high durability, climate controlled aluminium box.

Also included in the box:
* 40 meters of heavy duty electrical cable for connecting Junction box and Measurement device. The Measurement device side of the cable has an space grade plug. 
* GPS antenna
* GPS antenna extension cord. The antenna must not be in the field of strong radio signal(for example ships radar) and the cord provides flexibility of choice on position.
* Custom made fastenings. The drawing of the railing is necessary for us to manufacture the components.

''' Safety '''

The LASER in the measurement device is eye safe. See [[attachment:Safety_sheet_B22.pdf|declaration of safety]].
== System installation ==

[[Image(Photo of Measurement Device.png, 250px, right, top)]]

The Measurement device has robust attachment points along the longest edges.
The customers needs to specify where the device is meant to be installed. A drawing of the railing is
necessary for us to manufacture the appropriate fastenings.


The Junction Box should be installed indoors. The enclosure of the Junction Box is
not weatherproof nor climate controlled. It is a metal box that will be mounted on
a wall. It requires power and Local Area Network connections. The image below shows the
typical setup.

Example of installed measurement device is shown below.

The system may be accessed from any computer on the same network. If the ship does not
have any computer networks the computer in the Junction box will act as a system router
and provide network control.
