Please note that the channels MAX SPD and AVERAGE SPD can be accessed when the SL50 is
master. By default, these channels are calculated using the surface speed, and in the absence of the
latter it will be calculated using the bottom speed. These average and maximum values are calculated
from the last power-up of your installation. You can reset these channels to zero, without switching off
the bus : select the channel MAX SPD and AVERAGE SPD then press the key for 2 seconds.

1.4 Channel selection
Using the remote control, configure the display according to your requirements. Examples of
configuration:
Procedure
-Using the keys and , you can select in the list the channel you wish to display.
-The new channel to display is recorded.
1.5 What is a sub-channel
The sub-channels are made to modify setting and display parameters of the channels. For
example, the sub-channels of the surface speed channel are:
-the offset and the calibration coefficient : setting parameters of the log-speedometer
sensor,
-the measurement unit : in knots or in km/hr,
-the filter setting,
-the setting of the upper alarm and the lower alarm.
The same applies to all channels present on the TOPLINE bus. The following chapters provide
detailed explanations on how to access the sub-channels and implement the settings.
CAUTION : if your installation is equipped with several TOPLINE displays, make sure that
the remote control controls the display which you wish to operate. Press the key
repeatedly, until the intended display blinks.

1.6 Alarms setting
The setting of an alarm enables you to monitor the value of a channel. When the preset
threshold is exceeded, a warning message is displayed and an audible alarm is activated. For
example, you can set an upper threshold and a lower threshold on the surface speed channel.
The upper alarm is activated when the display is higher than the programmed threshold.
The lower alarm is activated when the display is lower than the programmed threshold.
To cancel the alarm of a channel, enter the value 0in the upper alarm and the lower alarm.
Thus, the setting of the alarms will allow you to supervise your TOPLINE installation effectively
as well as the good operation of your boat.
Note that for angular channels such as magnetic heading or wind angle, the sub-channels of
alarms are the alarm base and the alarm range.

1.7 Filtering of the channels
The level of filtering of a channel determines the frequency of update of the data displayed.
For example, in rough sea when the boat moves significantly, it is useful to increase the filtering
of the speed channel to stabilise the value displayed. Conversely, in calm sea, low filtering will
be preferable to obtain a fast response of the display.
Filtering is adjustable between 1and 32, and the default value is 8. The lower this value is, the
higher the frequency of update is.

2.3 Autocompensation of the fluxgate compass
Please refer to the compass user manual before starting the autocompensation procedure.
In order to achieve a successful autocompensation, you must navigate :
-On smooth sea, with no current and no wind.
-Away from large magnetic masses such as cargo boats.
-In an open area allowing the execution of a circle with a diameter approximately 5 times the
length of the boat.
-At a constant speed of about 2 or 3 knots.
Procedure
1. Select the magn head channel,
2. Start to describe the circle, then press the 2 second on the key ▼, to launch the
autocompensation procedure.
3. One single circle*is sufficient to perform the autocompensation correctly, when its a
success, the message 3000 is indicated.
* For the previous generation of compass, referenced as 90-60-005, at least three circles
must be executed.
In case of problem during autocompensation, the SL50 displays the PAN message , plus one
code :
-Code 1 : cancellation at user request.
-Code 2 : detection of a gyration in the opposite direction. Start again clockwise.
-Code 3 : excessive variation between 2 heading measurements. Reduce the speed of your
boat to 2 or 3 knots.
-Code 4 : angle correction higher than 20°. Start the autocompensation procedure over.
In case of autocompensation error, the measurements are not saved to the memory and the
sensor resumes its normal operating mode.

Before contacting technical support, please check the troubleshooting table below.
Problem Possible causes and solutions
The Topline installation does not detect the SL50
The bus cable is not or is badly connected to the terminal box : check the
plugging and the connection inside the terminal box. Check the state of
the cables : they must not show any sign of wear or cut.
The remote control does not control the SL50 The address of the remote control is lower than that of the SL50 :
reinitialise the remote control, see chapter 17.
The SL50 is set at the address « 0» : perform its initialisation, see
chapter 17.
The SL50 displays the message « data wire error » Check that the black data wire is connected at the right location in the
terminal box : see chapter 17
The SL50 displays the message « collision error » It is possible that there are two master displays (at address 1) on your
installation : check the addresses, if it is the case, reinitialise one of the
displays.
The SL50 does not display the NMEA data : that from the GPS
for example.
Has the NMEA link been initialised ? see chapter 16
The NMEA link is not or is badly connected to the terminal box : check
the connection of the SL50 and that of the NMEA transmitter (GPS).

3.8 SL50 and remote control initialisation
At first power-up, you must initialise the SL50 so that an address is assigned to it. The display
is delivered with the address set as 0. During the initialisation, it will automatically insert itself in
the list of instruments and displays of the TOPLINE bus of your installation :
−either as master, at the address 1,if this address is available on the bus,
−or as slave, if the address 1 is taken by a master, at an available address comprised
between 2and 20.
Likewise, the remote controls must also be initialised. Please refer to the remote control user
guide.
3.8.1 Initialisation procedure: the SL50 is set at the address 0
-your installation is powered off : disconnect the initialisation red wire from the init terminal
(GND),
-power up your installation : the SL50 then performs an auto-test,
-when the message «connect the red wire» appears, reconnect the red wire on init (GND) :
the SL50 takes an address available on the bus,
-the SL50 is then initialised.
3.8.2 Reinitialisation procedure : the SL50 already has an address between 1 and 20
You may need to reinitialise the SL50, for example to have another address assigned to it.
-your installation is powered off : disconnect the initialisation red wire from the init terminal
(GND),
-power up your installation : the SL50 performs an auto-test then takes the address 0,
-when the message «connect the red wire» appears, reconnect the red wire on init (GND) :
the SL50 takes an address available on the bus,
-the SL50 is then initialised.
CAUTION :
−the remote control(s) of your installation must be assigned to an address higher than the
one of the SL50. To achieve that, you must first initialise the SL50 then the remote
control(s).
