Introduction
INTRODUCTION
Efficient fishery with trawl and purse seine assumes professional
and adequate instrumentation on the gear. Simrad has provided
professional instruments for fish finding for more than sixty years.
This user manual described installation, use and maintenance of
the PI Remote/Depth sensor when put to use with the PI catch
monitoring systems.
Purpose and applications
The purpose of the PI Remote/Depth sensor is to achieve accurate
measurements of both the water depth and the distance between
the two trawl doors. In order to measure the distance, it must be
installed in a pair with a PI Spread or PI Spread/Depth sensor.

316870/A 5

Simrad PI Remote/Depth
The PI Remote/Depth thus contains both a pressure sensor to
measure the water depth, and a transducer to communicate with
the PI Spread sensor. The sensor in the PI Spread sensor will then
measure the distance between the trawl doors. The results from
these measurements are transmitted by acoustic signals to the PI
catch monitoring system mounted on the vessel.
Note
Each Spread sensor can be configured to communicate with one
of two Remote/Depth sensors; Remote 1 or Remote 2. Label the
Spread sensor accordingly, and ensure that you only use the
sensors in the correct pairs.
The PI Remote/Depth has been developed to be used on both
bottom and pelagic trawls. The sensor is installed on the
starboard trawl door using an adapter.

Simrad PI Remote/Depth
INSTALLATION
The PI Remote/Depth sensor is mounted on the starboard
trawl door using a special adapter. From this position, it will
communicate with a Spread or a Spread/Depth sensor on the port
trawl door, and with the hydrophone beneath the vessel.
Sensor installation
The PI Remote/Depth sensor and the Spread or Spread/Depth
sensors must be mounted in dedicated adapters on each trawl
door. These adapters must be installed beforehand. Detailed
information on how to install the adapters are provided with the
installation kit.
The PI Remote/Depth sensor is mounted on the starboard door,
while the PI Spread (or PI Spread/Depth) sensor is mounted on
the port door.
Note
It is essential that there is a clear line of sight between the two
transverse communication “eyes” (one on each sensor). It is
also important that both the PI Spread (or Spread/Depth) and
the PI Remote/Depth sensors have a clear line of sight to the
hydrophone on the vessel.
The two rubber inserts provided at the bottom of each sensor
adapter must not be replaced with any other types or designs.
It is essential that these inserts provide a secure cradle for the
sensors, but they must also allow for free water circulation to
allow the sensor’s water switch to engage. Also, the design of
the inserts allows sand and mud to flow out when the trawl doors
are pulled up from the water.
Adapter installation
The installation of the sensor adapter is described in the dedicated
instruction manual provided with the adapter. The document can
also be downloaded from www.simrad.com.
Note
The adapter used to install the PI Remote/Depth sensor is not the
same as the adapter used for the standard PI Remote sensor.
The PI Remote/Depth sensor uses the same physical housing
as the PI Spread and PI Spread/Depth sensors, but it must be
mounted “upside down” to establish free view between the two
transducers used for the transverse communication.

Simrad PI Remote/Depth
CONFIGURATION
In order to allow the information from the PI Remote/Depth
sensor to be accepted and understood by the PI catch monitoring
system, the PI receiver must be set up correctly. This means that
you must tell the receiver that the sensor exists by entering the
sensor type, communication channels and update rate.
Upon delivery, all PI Remote/Depth sensors are set up with
factory default channels and update rates. Refer to the table in
section About sensor configuration on page 14.
Note
The sensor and the PI system setup must correspond, otherwise
the communication will not work. To change the sensor setup
(channel selection and update rate), use the PI Configurator
utility. See PI Configurator on page 16.
Basic configuration
Observe the following basic configuration settings:
• When you put the PI Remote/Depth to use, you must set it
up with a unique sensor number. Select the update rate, and
use a channel number according to the sensor’s configuration.
Write down this configuration for future reference. For
default settings, refer to the table in section About sensor
configuration on page 14.
• On the receiver, the Interference filter must be switched
on.SetittoLevel9if you have noise problems from other
hydroacoustic sources. Note that this filters will influence the
signal spectrum shown in the Status display.
• We recommend that you set the sensor filter to Light.
Configuration of the PI32
This procedure explains how to set up the PI32 catch
monitoring system to access the information provided by the PI
Remote/Depth sensor. For more detailed information about the
PI32 settings and parameters, refer to the PI32 Operator manual.
Note
In order to set up the PI system you must know what kind of
sensors you have, which communication channels they use, and
how often they communicate (the update rate). You need this
information before you start the configuration.
Do not carry out sensor configuration unless absolutely
necessary.

Adding a Spread/Depth sensor
In order to achieve full control of the trawl, you may wish to
add a Spread/Depth sensor on the port trawl door. This sensor
will communicate with the Remote/Depth sensor to establish the
distance between the trawl doors, and it will provide you with the
accurate depth of the port trawl door. The Spread/Depth sensor
will occupy one additional channel on your PI system.
Note
You will not be able to add a PI Spread/Depth sensor on a PI32
system.

Changing a communication channel
It may be required to change one or more communication
channels, and there may be many reasons for this.
• You have more than one of each sensor. For example, if you
have three temperature sensors, they MUST communicate
on three different channels.
• Other vessels near your use the same PI catch monitoring
system (or a similar), and they have one or more of their
sensors set up to the same communication channels as you
have. This will create interference, as you will "read" each
others sensors.
• If your sensors are set up to use communication channels too
close to each other (for example, you have chosen channels 4,
5 and 6), this will limit the vessel’s speed. The reason for this
is the Doppler effect. If the speed is too high, the Doppler will
cause the transmission frequencies to change so much that
they overlap, and this will create interference. The PI catch
monitoring system will provide a warning if this is about to
happen! You must then either change to other communication
channels further apart, or reduce the maximum shooting speed.
• If you operate at the maximum range of the sensors, you
may be able to increase this range slightly if you use
lower communication channels. This is because the lower
communication channels user lower transmission frequencies.
Changing the update rate
It may be required to change the update rate on a sensor, that is
how often it sends information back to the PI catch monitoring
system. A high update rate will give frequent information
updates, but the sensor will use more battery power. If you need
your batteries to last as long as possible, you must consider
lowering the update rate.
• A low update rate will provide you with fewer information
updates, but the battery will last very long.
• A high update rate will give you frequent information updates,
but the battery will run out faster.

Simrad PI Remote/Depth
All sensors are provided from Simrad with a default update rate
setting. In some cases you may find that this update rate does not
suit your operational needs. This is a decision you have to make
depending on the local fishing conditions.
PI Configurator
Simrad has developed a dedicated computer utility to change
the sensor configurations. By means of an ordinary desktop
computer and a few special cables you can do this job yourself. If
you do not require frequent configurations, you can also contact
you local dealer for assistance. Contact the dealer for more
information.

This example shows how the trawl door is located at 45.9 m
depth, and that the distance between the trawl doors is 25.6
meters. You can also see how these values have changed during
the last 20 minutes.
The purpose of the depth- and distance markers on the graphical
presentation is to keep an eye on how deep and how far apart the
trawl doors are situated. The depth sensor in the PI Remote/Depth
measures the distance from the sea surface and down. The PI
Spread sensor communicates with the PI Remote/Depth sensor to
measure the distance between the trawl doors.

sensor is connected to the PI32 with correct communication
channels and update rates.
