• With
Auto
enabled , the priority list is used. Information is imported from the sensor
at the top of the list. If the sensor fails to provide information for more than 20
seconds, data from the next sensor is used.
• With
Auto
disabled , the priority list is not used. Information is imported from the
sensor at the top of the list. All other sensors are ignored.
6 If you wish to control the datagram priority manually, do not select
Auto
.
To change the priority for a given datagram, select it, and change its location on the list
using the arrow buttons.
7 If relevant, add a manual value for the sensor input.
8 At the bottom of the dialog box, select
Apply
to save your settings.
9 Repeat for each sensor interface that you need to set up.
10 Continue your work in the

Setting up the input from a motion reference unit (MRU)
The information from a motion reference unit (MRU) (normally heave, roll and pitch
information) is imported into the ST90 system to increase the accuracy of the echo data. The
ST90 system is provided with a built-in motion sensor to provide electronic stabilization
of the sonar beams. It is placed inside the Motor Control Unit. For improved operational
accuracy, an external motion reference unit (MRU) can be used.
Prerequisites
This procedure assumes that:
• You have a vacant interface port on your Processor Unit.
• You are familiar with NMEA and other relevant datagram formats.
• You know how to set up the parameters for serial and local area network (LAN)
communication.
• The interface port is set up with the correct communication parameters.
• The ST90 system is turned on and operates normally.
• The new sensor is physically connected to the ST90 system using a serial or network
cable. The sensor is turned on and in normal operation.
Neither tools nor instruments are required.
