in dry dock. The transducer will be damaged if it
transmits in open air. To prevent inadvertent use of the
sonar, pull out the mains plug on the Sonar Processor
Unit whenever the vessel is in dry dock.

High voltage safety warning
Precautionary measures
The voltages used to power this equipment are
potentially lethal. Even 110 volts can kill.
Whenever possible, the following precautionary
measures must be taken before any work is
carried out inside the equipment:
•Switch off all high-voltage power supplies.
•Check the operation of any door interlocks
and any other safety devices.
•Completely discharge all high-voltage
capacitors.
It should be noted that interlocks and safety
devices are normally located only at regular
access points, and high voltages may be exposed
during dismantling.
Never work alone on high-voltage equipment!
First aid in the event of electric
shock
Normally, even a high voltage electric shock will
not kill instantly. The victim can still be revived
even when his breathing and heart-beat have
ceased.
Could YOU save someone’s life?
In the event of electric shock, the correct actions,
performed quickly may well save the victim’s
life. Make sure you know what to do!
Immediate action:
While shouting for help, remove the source of
power from the victim. Switch off the supply if
possible, or using a dry, non-conductive material
(rubber gloves, broom handle etc.) to insulate
yourself, separate the victim from the source. If
the voltage exceeds 1000 volts, switch off the
supply and be ready to catch the victim. Take
care- do not become a victim yourself.
Commence first aid on the spot. Continue to shout
for assistance till someone arrives.
1Lay the victim flat on his back and loosen
any tight clothing (collar, tie, belt etc.).
2Open his mouth and check for and remove
any false teeth, chewing gum etc.
3Check if the victim is breathing. If not,
check if his heart is beating. The pulse is
normally easily found in the main arteries
of the neck, either side of the throat, up
under the chin.
If his heart is beating but he is not breathing,
commence artificial respiration. If the victim’s
heart is not beating, commence external cardiac
massage (ECM). Continue to shout for assistance
till someone arrives.
External cardiac massage
1Kneel beside the victim. Place the heel of
one hand in the centre of his chest, at a
position half way between the notch
between the collar-bones at the top of his
chest, and the dip in the breast-bone at the
base of his rib cage. Place the other hand
on top of the first.
2Keeping the arms straight and using your
entire weight, press down rapidly so that
the breast bone is depressed four- five cm,
then release the pressure. Repeat
rhythmically at a rate of one cycle per
second. This will be hard work, but keep
going. His life depends on YOU. Do not
worry about breaking his ribs - these will
heal if he survives.

Installation manual
VII
851-164510 / Rev.E
Artificial respiration
1Kneel besides the victim’s head. Place one
hand under his neck and lift, allowing his
head to fall back. This will lift his tongue
and open the air passage in his throat.
2Place the palm of the hand on his forehead
to maintain the ”chin-up” position.
3Using the index finger and thumb of the
same hand, pinch the victim’s nostrils
closed. Open his mouth.
4Take a deep breath and cover his mouth
with yours. Blow steadily into his lungs to
expand his chest. Remove your mouth
from his to allow the air to escape from his
chest. You should be able to see his chest
deflate.
5Repeat the ”inflation-deflation” cycle at a
rate of about 12 cycles per minute till the
victim begins to breath normally again.
Combining ECM and artificial
respiration
If you are alone, perform one cycle of artificial
respiration for every five cycles of ECM. This
will be hard work, but keep going. His life
depends on you!
If there are other people available to help, one
should perform the ECM while one performs the
artificial respiration for every five cycles of ECM.
It will be much more efficient with two people.
Once the victim’s heart is beating and he is
breathing, roll him onto his side and support him
in that position. As consciousness returns he may
vomit, and this will allow any liquid to drain out
of his mouth.
Remove the victim to a hospital as soon as
possible, but do not interrupt the artificial
respiration and ECM cycles till his heart beat and
breathing returns.
If started quickly and performed correctly, the
resuscitation methods described will keep a
sufficient volume of oxygenated blood flowing
trough the victims body to allow full recovery.
Proficiency in the resuscitation methods can only
be achieved trough training. All personnel
concerned should attend courses on a regular
basis. Remember, someone’s life could depend on
you.
Do you know what to do?

1.4 Peripheral equipment
Required inputs
The Simrad SP90 sonar system requires input from both a speed
log and a course gyro. Inaccurate data from either of these
instruments will result in an incorrect indication of vessel and
target movement.
Speed log
The speed log parameters are:
•Pulse log: 200 pulses / nm.
•Serial line, standard NMEA 0183, RS-232
→Also refer to (D)GPS below.
Course gyro
The course gyro parameters are:
•Serial line, standard NMEA 0183, RS-232
An optional gyro interface box for converting the following
synchro and stepping gyro signals can be ordered from Simrad:
•3-phase synchro signal, 20 to 150 V L-L, 50/60/400 Hz, gear
ration 1:360 or 1:180
•3-phase stepper signal, 20 to 150 V L-L, gear ration 1:360 or
1:180
→Refer to page 6 for the Simrad order number.
Additional inputs
In addition to the pulse log input described above, the SP90
sonar provides a total of seven RS-232 serial lines. Since one is
used to interface the course gyro, the remaining six serial lines
maybeusedfor:
•Differential Global Positioning System - (D)GPS
•Echo sounder
•Purse seine system
•Trawl system
•Current meter system
•Radio buoy system
Differential Global Positioning System - (D)GPS
A (D)GPS may be interfaced with the Simrad SP90 sonar to
establish the vessel’s position and provide cursor and marker
latitude and longitude.

Simrad SP90
8851-164510 / Rev.E
Note that in addition to navigational data, the (D)GPS may also
be used for the input of speed log information. Most (D)GPS are
equipped to present course information, but this data is
generally too inconsistent to provide a stable sonar presentation.
The (D)GPS parameters are:
•GPS data: RS-232 Serial line, standard NMEA 0183.
Echo sounder
To provide depth information on the catch control page of the
sonar’s display, echo sounders may be connected:
•RS-232 Serial line, standard NMEA 0183
Catch monitoring system
To provide trawl and purse seine depth information on the
sonar’s display, the following Simrad catch monitoring systems
may be connected:
•Simrad PI30 Catch monitoring system (RS-232)
•Simrad PI32 Catch monitoring system (RS-232)
Trawl system
To provide trawl information on the sonar’s display, one of the
following Simrad trawl systems may be connected:
•Simrad FS903 Trawl sonar system (RS-232)
•Simrad FS3300 Trawl sonar system (RS-232)
•Simrad ITI Integrated Trawl Instrumentation system
(RS-232)
Current meter system
A current meter system may be connected to the sonar to display
the direction and speed of the sea currents on various depths.
The following current system can be connected:
•Kaijo DCG-200
The current meter system is interfaced by means of an RS-232
serial line.
Radio buoy system
A GPS based radio buoy system may be connected to the sonar
to show the position and buoy data on the display. All are
interfaced by means of an RS-232 serial line. The following
buoy systems can be connected:
•SERPE
•Ariane
•Ryokusei
