Simrad SN90 Reference Manual
Installation
Before you use the SN90 system you must set it up to communicate with the
relevant peripherals. This includes the transducer. Use the
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.
This dialog box contains a number of pages selected from the menu on the left side.
The following pages are provided:
Sensor Installation
For the SN90 system to use and offer correct navigational information, one or
more external sensors must be connected. Typical sensors are those providing
navigational information (heading, speed or geographical position). Use the
Sensor Installation
will import information from. You must also specify which datagram formats
to use. For each relevant sensor you must insert the offset values that define
the its physical location relative to the vessel's coordinate system.
Sensor Configuration
With multiple sensors connected to the SN90 system, many of them will
provide the same datagrams. We cannot expect that these datagrams provide
the same information. The
a datagram priority, so that the information from the "most reliable" sensor
is used by the SN90 system. You can also define manual values in case a
sensor is unserviceable, or not installed.
I/O Setup
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
parameters on the
of the available communication ports. For each port, you can set up the
communication parameters, and monitor the data flow.
Motion Reference Unit
The motion reference unit (MRU) measures the roll and pitch movements
of the vessel. Some sensor models also measure heave. The information
provided by the motion sensor is used by the SN90 system to stabilize the
beams.

All relevant system units and sensors must be defined with their physical
offset values in relation to the defined Ship Origin in the vessel's coordinate
system. You will only need to define these installation parameters once.
