SeaHub 

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, 
otherwise follow the manual driver installation procedures below.
