1. Introduction
In order to be used as a bathymetric survey system the Gemini Profiler will be used
in conjunction with additional software. Details are presented here for the EIVA
NaviScan software package.
The basic principle of operation is that the Gemini Software communicates with the
sonar head and then sends out data in a compatible format to the survey software.
Usually the survey software is installed on a separate computer and they are connected
via a network link.
Note
For more details of the software and after sales support for NaviScan
please contact your sales representative or visit the EIVA website at
www.eiva.com.

2. Hardware Setup for EIVA NaviScan
It will be necessary to run the Gemini Profiler off one computer and the EIVA
NaviScan software on another computer. The two computers will be connected
through an Ethernet LAN.
The survey system should be connected as follows:
Figure 2.1. EIVA NaviScan Hardware Configuration

3. Configure the Gemini Software
To set the Gemini software for use with a survey computer running EIVA NaviScan
it will be necessary to configure the data output over an Ethernet port. The computer
running the Gemini software will essentially be connected to two LANs, one for the
Gemini Profiler head(s) and the other for the connection to the survey software.
Note
The computer running the Gemini software and the computer running
the NaviScan software should be assigned IP addresses within the same
subnetwork.
The network settings for the connection to NaviScan are located in the section titled
Set up network data output in the Digitisation section of the
Advanced tab (as shown in Figure 3.1, “Gemini Software Digitisation Settings”).
The Format should be set to Tritech and the Hostname set to the IP address of
the computer which is running NaviScan.
Figure 3.1. Gemini Software Digitisation Settings
Once the network has been properly set it will be necessary to configure the Hub
Setup so that the data from auxiliary sensors is passed through correctly.
In the Hub Setup tab ensure that the time synchronisation is set to GPS and the
network data output is Framed.

4. Configure EIVA NaviScan
In order to set up the Gemini Profiler it will be necessary to launch the NaviScan
Config dialog. Each of the steps outlined below are performed with this dialog as
a starting point.
4.1. The Gemini Profiler
From NaviScan Config click on Equipment→Add sensor.
Figure 4.1. NaviScan Config
Next, select the Echosounder option.

The Port settings window will now appear. Set the Port type to UDP/IP
Port and enter the IP Address and IP Port number of the Gemini computer that will be
used for the connection (as configured in Chapter 3, Configure the Gemini Software).
Note
The example in Figure 4.4, “Echosounder Port Settings” shows a
computer running the Gemini software that is configured to use an IP
address of 192.168.2.100 on Port 52905 (the default communication port).

4.2. 3rd Party Sensors
To add in any 3rd party sensors to be used with the system such as GPS Position,
Motion Sensor or Gyro Compass launch the NaviScan Config dialog and select
Equipment→Add sensor.
Position Sensor over UDP
To add in a sensor that is connected via the UDP interface first select
Equipment→Add sensor:
Figure 4.6. Choose Position Sensor

In the Port settings dialog that is present select the UDP/IP Port option and
make sure the IP Address and Port match the computer running the Gemini Software
(in the example shown, the Gemini computer is on IP 192.168.2.50 using Port 52905).
Figure 4.7. Select and Configure UDP Settings
Note
For UDP connections, make sure the Network data output is set
to Framed in the Gemini Software as shown in Figure 3.2, “Gemini
Software Hub Setup”.
Other Sensors
Repeat the steps outlined for the Position Sensor over UDP to connect
all the other sensors required for the system (e.g., GPS, Motion Sensor
and Gyro).
GPS Time Over Serial Connection
If desired, it is possible to connect serial sensors directly to the computer running
NaviScan. An example is shown here using GPS Time data, but the steps can be
followed for any relevant serial device.
Select Equipment→Add sensor:

The Time message and PPS (using CTS) must be connected over a serial
connection directly to the NaviScan computer (see Figure 2.1, “EIVA
NaviScan Hardware Configuration”).
