SeaHub
3.2. General Overview
The “SeaHub Surface Interface Module” is designed to be a portable and universal interface box
providing a single module solution for interfacing the range of Tritech’s sub-surface products (sonars,
acoustic modems and other undersea sensors) into a PC computer or Laptop.
Power In
The module may be powered from either a “universal mains” AC power-supply, or a DC power input over
the +12 to +36V range, allowing operation from batteries, bench-power-supplies - please refer to section
5 (page 34) for further details and safety instructions.
Communications
Tritech’s sub-surface products, or other supported peripherals may be connected to the ‘AIF ArcNet’ port
or alternatively to one of four communication ports on the rear of the unit. Under software control, the
hardware communication standard of each port may be selected, and these include; ArcNet LAN, RS232
(3 and 5 wire variants), RS485 (Half-Duplex), RS422 (Full-Duplex) and RS232 (Full-Duplex) – although
not all standards are supported on each port, refer to section 6.3 on page 40 for further details.
The front of the module provides LED status indicators for power and the selected communication mode
on each of four communication ports.
For more integrated connections, the ‘AIF ArcNet’ connector is provided giving access to +12V, +5V and
ArcNet signals – both TTL and Analogue variants. Additional legacy wiring configurations are also
supported on this connection, but consult Technical Support for further details.
Power Out
Tritech’s sub-surface products may additionally derive DC power if connected to either of the two 6-pin
“DIN” communications ports (labelled “C” or “D”). If the AC “mains” power input is being used, then the
output voltage on Ports “C” and “D” will be +28V(±5%)1, while a DC power source will have a fused
version of the input voltage available on the output instead – check compatibility with all devices before
connection, see sections 5.2 & 5.3 on pages 35 & 36 for details.
Further DC output power (and Earth) connections are provided for external devices through three 4mm
sockets on the rear of the unit. If the “mains” power input is being used, then the output is internally
jumper selectable from +28V (factory default, see note below), +12V or +5V, while a DC power source
will have a fused version of the input voltage available on the output instead.
NOTE
The +28V(±5%) DC Output, available when AC Mains power is applied, is the factory set
voltage which if necessary can be increased to a maximum of 36V(±5%) by internal
adjustments.
RAT
For sonar specific control, the front panel also contains provision for connection to a RAT (Remote
Access Terminal). However, only RATs with a PS2 “Togglestick” mouse-controller and RS485 serial
communications are supported.
USB
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.
1Factory set to 28V. Internal PSU adjustable up to 36V(±5%).

4. Operation
It is suggested that users installing the SeaHub for the first time should read through the following
sections in a sequential order, prior to proceeding. A ‘Quick Start’ Installation Guide will also be provided
as part of the supplied documentation.
This section covers the hardware installation of the SeaHub unit, software and driver installation on the
PC, configuration of the Seanet software, and connection of devices to the SeaHub. However, it does not
cover device specific use of Seanet – for further details refer to the Seanet Users Manual.
NOTE
Please be aware that Seanet Pro and the SeaHub drivers only support Windows 2000,
Windows XP and subsequent operating systems.
4.1. Hardware Installation
1) Unpack the SeaHub module from its transit case.
NOTE
Before connecting the SeaHub to the PC, ensure that Seanet Pro has first been installed
on the PC from the Installation CD provided, see NOTE below.
2) Connect the SeaHub module’s rear USB port (labelled “PC-USB”) to the PC/Laptop using the
USB cable provided. The SeaHub should be connected to a High-Speed (480Mbps) USB 2.0 port
to achieve maximum performance.
3) Connect the power supply to the SeaHub, and power up – this may be either using an AC mains
power supply, and the power cord provided, or a DC supply and the 2.1mm plug.
4) On the first successful connection and power-up to the PC, the Windows operating system may
start the “plug-and-play” detection of the SeaHub devices. If this happens, refer to “Windows
Drivers Installation” section below (in section 4.2) for further details.
The SeaHub driver package will be loaded across during installation of Seanet Pro from the
Installation CD provided. The SeaHub should be connected to the computer after this software
installation has completed which should ensure that the “plug-and-play” setup be automatic and
not require any user-intervention.
If the drivers have previously been installed on the PC then automatic detection will occur, and
the COM ports will be added. Seanet may be run at this point, although COM port allocation may
need to be checked.
4.2. Hardware Driver Installation and Configuration
4.2.1. Windows Driver Installation
This section covers the driver installation process for the SeaHub hardware on Windows 2000 and
Windows XP operating systems. Other operating systems are currently not supported.
NOTE
Before connecting the SeaHub to the PC, ensure that Seanet Pro has first been installed
on the PC from the Installation CD provided (refer to Section 4.3.1 on Page 20). During
this installation, the SeaHub driver package will also be loaded onto the PC. When the
SeaHub is then connected, “plug-and- play” detection and setup should be automatic,

1) On the first connection of a SeaHub to a PC System,
the plug-and-play system should start the automatic
detection and setup of the hardware.
If this fails to happen, manually start the process by
selecting “Add New Hardware” from the Windows
Control Panel, and follow the onscreen instructions
for detecting new hardware.
Add Hardware
The installation process normally occurs in two parts. First the driver for the “USB to Serial”
hardware is identified and installed; once this is done the driver for the “Virtual Communications
Port” (VCP) is then installed.
2) Once the “Found New Hardware Wizard” starts, a
window similar to that shown opposite should appear.
If your PC has an internet connection, you can select
“Install the Software Automatically”. This will search
the internet for the correct drivers, download and
install them – you will not need the driver CD.
Following this option means you may skip over the
next step.
For PC’s without an internet connection, select
“Install from a list or Specific Location”.
Click “Next” to continue.
3) Insert the SeaHub driver CD into the PC’s CD-ROM
drive and ensure the top check-box “Search
removable media” is ticked.
Alternately, copy the contents of the directory onto
the PC’s Hard-Disk and install the driver from there.
To do this, tick the “Include this location in the
search” check-box. Click “Browse” and select the
driver location. The drivers can be found on the
Installation CD at the following location…
<CD Drive>\SeaHub Drivers\WinXP_Win2000_Drivers
Click “Next” to continue.
4) The driver installation wizard will now try to find the
drivers – this process may take several seconds, so
be patient.
During this process and depending on the PC’s setup
prior to installation, the wizard may identify newer
versions of the drivers installed or from an alternate
source on the internet. Select the required driver and
continue.
When the drivers have been found and installed, the
wizard will show the screen opposite.
Click “Finish” to continue.

5) Windows may display a “speech” bubble showing the
new hardware has been detected and installed. Click
the “X” in the bubble to acknowledge it.
6) The plug-and-play system should now identify that
the Serial ports now need installing, for each USB-to-
Serial converter identified by the pervious part of the
installation.
This installation is the same process as before, so
repeat the above steps to locate the driver
7) When the process is complete, the following
“success” window should be displayed.
Click “Finish” to complete the installation.
8) Windows may display a “speech” bubble showing the
new hardware has been detected and installed. Click
the “X” in the bubble to acknowledge it.
9) If prompted, reboot the PC. The drivers should then
be installed and ready to use.

4.2.2. Identifying SeaHub Serial Ports
Having completed the driver installation procedure, the PC should have installed six “Virtual
Communication Ports” (VCPs) that map to Windows serial communication (COM) ports. These ports will
be removed when the SeaHub is disconnected or powered down, and reappear next time the SeaHub is
connected.
The exact allocation of these ports numbering will vary between systems, and depend on other PC
hardware present or previously installed. This section describes how to identify which ports are allocated
to the SeaHub – this allocation must then be used to correctly configure Seanet in subsequent installation
stages…
10) To determine which COM ports have been created,
right click on the “My Computer” icon on the Desktop,
then select “Properties” from the drop-down menu.
Alternately, double click on the “System” from the
control-panel.
System Properties
This will display the “System Properties” window, on
the “General” tab…
11) Select the “Hardware” tab in the “System Properties”
window, and then click on the “Device Manager”
button.

12) When the “Device Manager” window appears, this
will show all connected hardware to the PC.
Expand the “Ports (COM & LPT)” branch of the tree,
by clicking on the “+” symbol to its left. This will show
all the installed ports on the PC.
There should be six entries titled “USB Serial Port
(COMx)” in this list, each representing a serial port
within the SeaHub module. In the example shown
here, these are numbered from 9 to 14.
Make a note of these numbers, as the Seanet
software will need to be configured with them.
13) Close the “Device Manager” and “System Properties”
windows.

4.2.3. SeaHub Serial Port Functions
The SeaHub module will always install six serial ports when connected correctly to the PC. As mentioned
earlier, the operating system will allocate COM port numbers to these ports, and depending on the
system setup these numbers may vary.
However, the block of six SeaHub ports will always be installed sequentially in the following order…
SeaHub Port Functions
COM Port
Number Example
(see previous
example) Function
Base + 0 COM9 SeaHub Port A
These four ports will return serial data
from devices connected to respective
ports on the rear of the SeaHub, that
use RS232, RS422 or RS485
hardware modes. Ports C & D can
additionally be configured for ArcNet
device connections.
These devices may be Tritech
“SeaNet” compatible devices, or other
serial peripherals (i.e. GPS, Compass,
Modem etc.)
These ports must be configured in
Seanet, for the SeaHub and ArcNet
devices to operate correctly – see
section 4.3 below.
Base + 1 COM10 SeaHub Port B
Base + 2 COM11 SeaHub Port C
Base + 3 COM12 SeaHub Port D
Base + 4 COM13 SeaHub System Connection
This port returns “SeaNet” formatted
messages from devices connected to
Ports C & D, and the “AIF ArcNet”
connector, which use the ArcNet
hardware mode.
Additionally, RAT messages and
system control information to the
SeaHub, is sent via this port
This port must be configured in
Seanet, for the SeaHub and ArcNet
devices to operate correctly – see
section 4.3 below.
Base + 5 COM14 SeaHub Auxiliary Reserved Port
This auxiliary port is reserved for
future use by SeaHub expansion
modules.
This port does not need to be
configured in Seanet, for general
SeaHub operation.

4.3. Seanet Software Installation and Configuration
4.3.1. Seanet Software Installation
1) Insert the “Seanet Pro” Installation CD into the
PC CD-ROM drive and run the “SerialSetup.exe”
program. Note: If the CD autoruns then select the
“RS-232 Installation” type from the menu page.
2) When the installation program starts, click “Next”
to continue.
3) Read the license agreement, then select the
“YES” option, before you can click “Next”.
Click “Next” to continue.
4) Choose the installation destination directory. By
default this will be “C:\Program Files\SeaNet”.
Click the browse button if you wish to change this
location
Click “Next” to continue.
5) Installation will then proceed copying files onto
your computer, and making 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 files are copied, you will be prompted to
restart the PC. Click “Finish” to reboot
immediately. Rebooting may be deferred by
selecting “No”, then clicking “Finish”.
