I.2 Glossary
The glossary contains a list of definitions and a list of abbreviations.
I.2.1 Definitions
The meaning of standard definitions as used in this manual are explained in Table 1: Definitions on page 4.
Redundant A device that is equipped with multiple part of the same type, for example a double pow-
er supply. This equipment will continue to function when one of the redundant part fails.
Heading users Navigation equipment that uses heading/course information for functioning.
Hardware The physical parts of the AlphaLine instrument.
LEDs Light-emitting diodes. These are used for signaling statuses of hardware and software
signals to the user.
Central alarm system /
Bridge watch monitoring System that is connected to all vital systems on a ship and that is able to give a central-
ized indication of the (alarm)status of all connected systems.
NMEA protocol Protocol standard for transmitting and receiving of asynchronous serial data sentences.
Talker Device which transmits data. This is usually called transmitter or TX.
Listener Device which receives data. This is usually called receiver or RX.
ISO GND Isolated Ground. This is a ground connection to be used for reference signal. It is differ-
ent from EARTH and should normally not be connected to EARTH.
Grounding point/stud Point on the chassis of the AlphaLine instrument which should be connected to the ship's
mass.
Printed Circuit Board A printed circuit board, or PCB, is used to mechanically support and electrically connect
electronic components using conductive pathways, or traces, etched from copper sheets,
laminated onto a non-conductive substrate.
(Galvanic) isolated Electrical separation of two circuits. There is no current flowing directly from one circuit
to another. Electrical energy and/or information can still be exchanged between the sec-
tions by other means, such as by induction or by optical means (like transformers or opto
couplers).
CAN bus Controller Area Network. This is a network based serial bus system used for exchanging
information. It is the advanced version of RS485/422 serial buses.
Reverse polarity protection This is a part of the power supply hardware that prevents any damage to the equipment
when the power supply is connected to the wrong polarity.
5 | Preface
ROT signal Rate Of Turn (ROT) signal indicates the course change of a ship in degrees per minute.
This signal can be analog using voltage or current, or can be an NMEA data signal.
Heading/bearing repeaters Navigation type of instruments displaying the heading/course of a ship.
Baud rate This is the transmission speed of serial interfaces in characters per second.
Transmitting interval The frequency at which complete NMEA sentences are being transmitted in number of
times per second.
Factory setting Instrument setting for backlight color, language, number of connected apparatus, etc. as
configured as a new instrument by the factory.
Flash memory Non-volatile type of memory. This type of memory retains its contents even when the in-
strument is turned off.
Firmware (Embedded) software inside the processors of the AlphaLine instrument.
Compass safe distance The minimum distances to equipment that will not cause an unacceptable deviation of
the ship's standard and steering compasses.

9 | Introduction
III Introduction
The Analog Interface Mk.2 converts analog to digital signals. Supported signals include 0-20 mA, +/- 5/10/20V and
potentiometer signals for use with dimmers or rudder feedback units. The Analog Interface Mk.2 converts the analog
signal to a digital MODBUS and IEC 61162-1 signal.
10 | Installation Instructions
1 Installation Instructions
This chapter describes the installation of the Analog Interface Mk.2.
1.1 Mechanical Installation
• CAUTION
• This product must be installed in accordance with the installation methods described in this manual. Acting
otherwise will void the warranty.
1.1.1 Supplied Parts
The Analog Interface Mk.2 is delivered as a fully assembled product. No additional assembly is required.
1.1.2 Dimensions
Carefully check the applicable drawing(s) of the instrument. See Mechanical Drawings on page 17.
1.1.3 Mounting Modules
The Analog Interface Mk.2 should be installed on a DIN-rail in a cabinet protected from the environment. Keep at least 5
cm of space between both sides of the interface for thermal emission and cabling space.
When the Analog Interface Mk.2 is removed for service or replacement, pull the DIN-rail clamp to release the interface
gently from the DIN-rail.
1.1.4 Module Electric Connections
For electric connections, see Electric Diagrams on page 18.
1.1.5 Module Power Supply
The Analog Interface Mk.2 has one 24 VDC (nominal) power input. Power consumption is approx. 200 mA. Connect to a
power supply > 1 A.
1.1.6 Connecting Rudder Feedback Unit MD/HD and Analog Interface Mk.2
The Rudder Feedback Unit MD/HD consists of a potentiometer output, combined with limit switches (Rudder Feedback
Unit HD only), that can be connected to the display unit via an interface.
Figure 1: Analog Interface Mk.2 Figure 2: Rudder Feedback Unit MD/HD
11 | Installation Instructions
Rudder may be connected to the AlphaLine instrument using a serial signal ($xxRSA sentence, first rudder field), or by
using the Rudder Feedback Unit MD/HD.
1. Set the DIP switches on the front as explained below to connect and configure the potentiometer correctly.

2. Connect the Rudder Feedback Unit MD/HD to the Analog Interface Mk.2. See Electric Diagrams on page 18.
Note To prevent signal error, the cable with analog signal from the Rudder Feedback Unit MD/HD to
the Analog Interface Mk.2 should be as short as possible. Position the Analog Interface Mk.2 as close
as possible to the Rudder Feedback Unit MD/HD. The analog signal cable must not exceed 20 meters.
12 | Installation Instructions
Ensure the analog signal cable is separated from high voltage and high current cables, by placing it in a
different trunk.
Note Position the Analog Interface Mk.2 in a cabinet where there can be no interference from electronics
such as frequency drives (i.e. use a different/separate cabinet).
• CAUTION
• Failure to observe these guidelines could lead to serious system malfunction or wrong rudder
information.
• WARNING
• The analog signal cable must be securely earthed to the Rudder Feedback Unit MD/HD side, using the
EMC cable gland. The other side of the cable should remain unearthed.
3. Check functionality by checking the LEDs.
• POWER LED - Steady green
• MODBUS RX LED - Blinking green
• MODBUS TX LED - Blinking red
• NMEA LED - Blinking red
• STATUS LED - Shows Functionality: OK - Steady green, ERROR - Steady red
4. Use the IEC 61162-2 interface COM 0 Modbus to connect the module to the display unit.
