Transceiver
The
Transceiver
page offers key information about each transceiver in use by the
SN90.
–
Transducer
By means of the
Transducer
page, you can run a reception test to test the individual
transducers. Any errors are then easily detected.
–
Noise
The operational performance of the SN90 Purse Seine and Trawling Sonar depends
on the noise conditions. It is essential that the noise signature is as low as possible.
•
Export
The
Export
dialog box allows you to export user settings, configuration files, message
logs and information related to the hardware and software troubleshooting.
•
Installation
Before you use the SN90 you must set it up to communicate with the relevant
peripherals. This includes the transducer. Use the
Installation
dialog box to set up all
interfaces with external devices, and to set up basic parameters related to installation
and operation. In most cases, you only need to do this once.
–
Sensor Installation
For the SN90 to use and offer correct navigational information, one or more
external sensors must be connected. Typical sensors are those that provide speed,
heading and geographical position. On the
Sensor Installation
page you define
which external sensors your SN90 will import information from. You must also
decide which datagram formats that will be accepted. Once a sensor has been
chosen, you must select the offset values that define the sensor’s physical location
relative to your vessel’s coordinate system.
–
Sensor Configuration
With several sensors connected to the SN90, many of them will provide the same
datagrams. We cannot expect that the datagrams provide the same information.
The
Sensor Configuration
page allows you to define a datagram priority, so that
the information from the "most reliable" sensor is used by the SN90. You can also
define manual values in case a sensor is unserviceable, or not installed.
–
I/O Setup
In order to communicate with peripheral devices, the Processor Unit offers several
serial and/or Ethernet (LAN) ports. The number of communication ports depends
on how your Processor Unit is set up and configured. The
I/O Setup
settings allow
you to define which information is imported by the Processor Unit.For each port,
you can set up the communication parameters, and monitor the data flow.
