ESN100 Operation and Installation Manual Chapter: Installation
Installation
e ESN100 comprises of 2 units and up to 2 transducers
ESN100-SB Control unit: is display contains a single NMEA output, dual NMEA input and a communica-
tion pair to the transceiver. An additional RJ45 connector can be used for LAN communication.
JB50E1-SA Transceiver unit; is unit contains connections for 2 transducers (of either 50 or 200kHz) a con-
nection for a single paired wire to the Control unit (Using RS485), and 24VDC power input. is unit can
be mounted on the bridge, with long cables coming from the transducers, or near the transducer for lower
noise.
e NMEA will typically be sent to a splitter to give the information to the bridge/alarm system and VDR.

Chapter: Introduction and Specication
Transducer installation
A transducer should be installed in an area securing optimal measurement free from noise and aeration.
It should be possible to draw a cone of +-60 degrees underneath the transducer without any objects entering
the cone.
Generally there should be nothing in front of or close to the transducer that can cause turbulence.
Transducers are normally installed in the turbulence free area in the foreship as close to the bow as pos-
sible within the rst 3rd of the ship. (see Aon g.)
A
Bubbles
Single transducer
installation
A
Bubbles
Side view
Bottom view
e transmitting surface of the transducer must be installed horizontally with no more than 5 degrees tilt.
If this is not possible a blister should be assembled. is should have at least 0.3m of at area around the
transducer, and be tear drop shaped.
Do not mount transducers close to the propeller or a of other hull installations (outlets, vents or other
protruding details). It is necessary to select a part of the hull that is submerged under all load and speed
conditions, and to avoid positions where air is trapped.
Refer to SKIPPER’s installation procedures in the appendix and on our web site www.skipper.no regarding
information about sea valve, tank installation, welding, cable glands etc.
Note:
• Protect the active element of the transducer and do not paint the surface.
Transmission in the air must be avoided! is may cause mechanical damage of the element.
Larger vessels are oen tted with two transducers, one fore and one a (see g.)
e fore transducer is the primary transducer, (normally 50 kHz).
e a transducer is a secondary transducer, (normally 200 kHz).
e a transducer may be troubled with aeration and noise and may not operate in speed >4-5 knots.
A transducer is mainly used to measure a depth in slow speed and shallow water.

Wiring
e transceiver unit may be positioned in any suitable dry area (IP56)between display unit and transducer.
Normally this will be near the bridge area for easy supply of 24VDC supply.
If the transducer(s) are forward then there is an alternative to position the transducer in bow area closer to
the transducer to avoid any electronic noise on the analogue signal between the transducer and transceiver.
Transducer cable type:
1 x shielded pair (twisted pair recommended if available)

Clamping the cables
Cables should be connected to WAGO connector, leaving approximately
3 cm of tail. They should be stripped with 6-7 mm of metal showing and
these should be connected as in the diagram above. A small screwdriver
with blade size approx 3.5 mm can be used. WAGO part no 210-719 is
ideal for this use.
Outer shields should be collected and grounded in a ground stud on the
edge of the cabinet. The outer insulation should be cable tied to the plastic
handle of the connector, and securely anchored nearby. The plugs when re-
tted, must be installed such that their clips are fully in the up position.

Alarm
ere are a number of alerts available. Shallow water alarm and power failure alert are mandatory. In addi-
tion there is a Deep water alert, power reduction, system error and time synchronisation alerts.
ese are sent as alarm/alert sentences on the NMEA and LAN output of ESN100-SB unit.
e recommended setup of alarms from the navigational echo sounder is that echo sounder alarms are to be
connected to CAM (Central Alarm Management). If the system fails, and there is no other system to detect
the failure, a relay is available within the JB40POW unit that should connected to an external beeper.
e ESN100 has two congurations of alarm NMEA formats available in the soware setup.
ALF: Is the NMEA standard complying with IEC62923-1/2:2018 and IEC62288:2014.
ALR is the older standard and may comply with IEC61924-2:2012 and IEC62288:2014 only by connecting
the “Power failure alarm relay”in JB50E1-SA to the external CAM. If no CAM is available, a beeper must be
connected to the power failure relay in JB50E1-SA, and on “power failure” the beeper will sound.
More information about the alarm settings is available in the alarm setup part of this manual.

Display description
e display is programmable and can be made to show what the user wishes.
It comprises of 5 information’s on the right, and 3 on the bottom. ese information’s can show parameters
of the system, or parameters being sent into the system from other equipment. ese parameters will, aer a
short time, slide o screen., Touching the screen will make them return.
All these parameters are selected by default, but can be changed to show whatever the user chooses. See the
User guide Runtime screen setup
Some parameters requires a password to enter, e.g.
transducer and output settings.
The password for all units is ‘service’. The password will
be remembered for 1 hour, or until reboot of the system.

SKIPPER Transducer setup
Once connected the system requires the installer to identify which transducer is connected to which of the 2
connectors. Both connectors can have a 50, 200 or combined 50/200 transducer tted. To select the correct
xture, start the system and go to the cong menus, and then the ES setup.
Here you can select the Transducer menu and by clicking on the transducer connector port you can move the
transducer to the appropriate area of the vessel, and select the transducer, by part number. is will change
the parameters to match your transducer.
If only one transducer is installed (to transducer 1) then “Transducer 2” must be set to position “Not con-
nected”.

NMEA In/Out Setup
e System has an internal RS485(isolated) communication to the transceiver.
To the outside world it has:
2 x NMEA (IEC61162-1) Inputs
1 x NMEA (IEC61162-1)output
1 x LAN (IEC61192-450) Port (In/Out)
This port can provide communicaon both by TCP/IP V4.0 or using IEC61162-450. If being used it requires a
network that does not exceed 20Mbits/second. The system will exert/receive a maximum load of 40 data-
grams/second
e communications menu allows the NMEA messages to be selected for the output
NMEA Outputs
Default is DPT output and ALARM outputs set to the ALF version of the standard. NMEA style sentences
will be shown as the 3 letter mnemonic when the sentence is sent or received.
