1. Introduction
The Tritech SeaHub Surface Interface Module is designed to be a universal interface box
providing a single module solution for interfacing the range of Tritech International Ltd sub-
surface products (sonars, acoustic modems and other undersea sensors) into a PC computer
or Laptop.
The SeaHub can be powered from a standard Mains power supply, or through the input DC
socket at the rear of the unit and is available in either a 19" Rack mountable solution, or as
a desktop unit.
The SeaHub can be connected to devices through a variety of communication protocols:
ARCNET; RS232 (3 and 5 variants); RS422 (Full Duplex) and RS485 (Half Duplex). The
front of the SeaHub provides a LED status panel which displays the communications protocol
selected for each Port.
The SeaHub also provides a built in DC power supply that can power units. This is intended
for testing purposes, but could be used where an alternative power source is not available.
The two DIN connector ports have power automatically present, but there is also the three
4mm sockets at the rear of the unit.
Note
The DC power output level from the SeaHub is controlled by an internal variable
resistor. See Chapter 4, Operation for more details.
Note
When powering the SeaHub from a DC power supply, the SeaHub will connect
the DC output to this supply but with approximately a 2V voltage drop.
For sonar specific control, the front panel also contains provision for connection to a RAT.
RATs with a PS2 “Togglestick” mouse-controller and RS485 serial communications are
supported.
At the front of the SeaHub two USB Type-A sockets are also provided for user specific
peripherals to be connected. Each socket is capable of delivering 500mA of current (to a self-
powered hub), and is protected accordingly.

3. Installation
3.1. Software Installation
Note
The hardware must not be connected to the PC prior to or during software
installation.
If any Seanet software is already installed on the PC this must be removed correctly using
Windows Control Panel - Add or Remove Programs (or Programs and Features
in Windows 7) prior to starting the software installation.
Note
The latest version of Seanet Pro can be obtained from www.tritech.co.uk
Insert the Seanet Pro installation CD into the PC CD-ROM drive - if autorun is enabled
a dialog will appear with installation options. If autorun is disabled then run the Setup.exe
from the CD.
When the installation program starts, click Next to continue.
Read the license agreement and if you agree to its terms select the YES option and click
Next to continue.
Confirm the installation destination directory (by default C:\Program Files\SeanetV2
but if you wish to change this click the browse button and select an alternative directory),
click Next to continue.
Installation will then copy files onto your computer and make entries in the Windows Registry,
this process may take several minutes. If any anti-spyware software is running this may warn
you that registry changes are being made, allow any changes to be made if prompted. Once

Installation SeaHub
0594-SOM-00001, Issue: 02 15 © Tritech International Ltd.
files are copied you will be prompted to restart the PC (if you wish to defer the restart select
No ), click Finish to continue.
If the installation has been successful two new icons will have been created on the desktop
for Seanet Pro and Seanet Setup.
3.2. Surface Hardware Installation and Configuration
Caution
The power should be turned off before making a connection between the sonar
head and surface controller (SCU or SeaHub).
Note
Prior to connecting the SeaHub to the computer, Seanet Pro must be installed
beforehand. See Section 3.1, “Software Installation” for more details.
• Connect the computer USB port on the rear panel of the SeaHub to a USB 2.0 port on the
User computer with the supplied USB cable assembly.
• Connect power to the SeaHub and switch on. The indicator LEDs on the front of the unit
will flash and the ports will auto-install on the computer - this will take a minute or so to
complete and you may be prompted to re-boot the computer.
• If the computer does not automatically load the drivers for the SeaHub some additional
steps may be required. See Section 3.3, “Driver installation for SeaHub and NavHub”
for more details.
Note
The Rack mount version of the SeaHub has a power switch located at the rear
of the unit, next to the IEC connector. There is also a power switch at the front
of the unit. Both of these must be activated when power is applied in order to
switch the unit on.
There should be 6 COM Ports detected by the computer once all the drivers have been fully
installed:
SeaHubMain This is the main port used to communicate and control with the SeaHub
and ARCNET interface.
SeaHubA This is the port used to communicate via PORT A of the SeaHub
SeaHubB This is the port used to communicate via PORT B of the SeaHub
SeaHubC This is the port used to communicate via PORT C of the SeaHub
SeaHubD This is the port used to communicate via PORT D of the SeaHub
SeaHubAUX This is the port used for additional communication options. It is not user
accessable.
The actual port numbers may vary from computer to computer.
Basic Setup
The Seanet software must now be configured for the SeaHub – click the Seanet Setup
icon on the desktop to run the Seanet setup program.

Installation SeaHub
0594-SOM-00001, Issue: 02 16 © Tritech International Ltd.
From the drop down menu at the top of the screen select Utilities then Com Setup.
The Channel Setup page will now be displayed on screen. If this is the first time the SeaHub
has been used on the computer an additional dialog box will be shown to indicate that a
SeaHub has been detected.
Click Yes on this pop up and the Channel Setup page will then automatically add and
enable the main COM Port for the SeaHub.
Adding Additional Devices
The Channel Setup page controls all the serial based information that is intended for use
by Seanet Pro. The initial setup will only enable the SeaHubMain port, so the remaining ports
will need to be manually configured.
From the drop down menu select New.

Installation SeaHub
0594-SOM-00001, Issue: 02 17 © Tritech International Ltd.
A list of all the potential devices that Seanet Pro can accept data from will be displayed.
To add a new Port from the SeaHub, select the AIF option. The new AIF device will be
added to the bottom of the list of available devices.
To allow for all four ports of the SeaHub, repeat this process a further three times.
Once the addition AIF devices have been added, use the left and right arrows within the COM
Port to identify the various ports on the SeaHub.

Installation SeaHub
0594-SOM-00001, Issue: 02 18 © Tritech International Ltd.
Once all the ports have been identified, the Enabled box can be checked for each port that
is required.
Note
Seanet Pro will expect a data stream from each enabled AIF device. If no data
stream is detected a ComAif Error TMO error will be reported.
Once all the required ports have been setup and enabled, close the Channel Setup page
using the close icon at the top right of the page.
3.3. Driver installation for SeaHub and NavHub
When connected to a computer for the first time, the computer will attempt to load the
drivers for the attached device. For Windows based computers the process is largely similar
regardless of the operating system being used.
Note
The screenshots shown are example ones for a Windows 7 installation. Later
editions of Windows OS may vary, but the same basic steps are still applicable.
If required, contact Tritech International Ltd for more advice and support.

Installation SeaHub
0594-SOM-00001, Issue: 02 19 © Tritech International Ltd.
Driver installation
The system Tasktray will display an icon indicating that it is attempting to load the drivers.
Click on the Tasktray icon and the Driver Installation Window will appear.
By default, Windows will try to load the latest drivers from the Windows Update service, but
this is not required as all the appropriate drivers are installed along with Seanet Pro. Click on
the Skip obtaining drivers from Windows Update link.
Click Yes to continue. Windows will now search for the appropriate drivers on the computer.
After a short delay it should start to load the drivers and update the display.
During this process it is possible to see the COM Ports being allocated to the device. Use
the scroll bar to locate the numbers being allocated.
Once the process has been fully completed the device will be fully functional.

Installation SeaHub
0594-SOM-00001, Issue: 02 20 © Tritech International Ltd.
Checking the COM Ports
If the drivers are already installed, but the allocated COM Ports were not noted down at
the point of installation it is possible to check which Ports are available by using the Device
Manager. The simplest method for loading the Device Manager is as follows.
On the My Computer icon on the desktop (or within the Start Menu) right click and select
Properties. This will display the System Information window.
Click on the Device Manager link that appears on the upper left hand side of the window.
This will now display the Device Manager.
