7 NMEA UNITS

7.1 SAL 1N4 NMEA Buffer

Part number 704160

The SAL 1N4 NMEA Buffer is intended to interface /split NMEA serial data output where receiver system loads are high or unknown, or where a failure in one system must prevent other systems from being affected.

The SAL 1N4 has one opto-isolated input feeding four separate differential output drivers.

Installation, setup The unit should be bolted to a flat surface, preferably vertically and with wiring from below.

Wiring termination On the lower part of the unit an area is provided for securing the cables using wire straps.

Connection should be done using shielded cable and making sure the installation will be compliant with the EMC requirements of IEC 60945 it is necessary to make sure that the outer cable shield is securely connected to the chassis if the unit.

The simplest way to accomplish this is to remove the outer insulation of the cable and to fold down the screen on the outside of the insulation and to secure the cable with the straps supplied.

Input connection When connected to an output, the yellow input LED should light when the digital input goes active. With a normally working NMEA connection, this LED will flash as data are received and will be unlit between messages.

If the opposite indication is observed, the input terminals “A” and “B” should be reversed.

Output connection The unit has four RS422/485 based output pairs. Each output will drive several NMEA 0183/IEC 61162-1/-2-compliant inputs. The output drivers are not galvanically isolated from the power source, but the NMEA 0183/IEC 61162-1/-2 standard requires all inputs to be opto-isolated.

Output terminal “A” should be connected to input terminal “A” of the receiving equipment, which in some cases is marked “+”. “B” connects in the same way to “B” (or “-“).

Doc ID:703826A3, SAL R1a Section D Accessories.doc 16 (25)

It is in most cases possible to feed also RS232 inputs if this is required. To avoid feeding signal current into the RS232 signal ground, the NMEA output terminal “A” should be connected to RS232 Rx terminal, while the NMEA output terminal “C” should be connected to signal ground of the RS232 input.

Specifications Indications Green LED indicates DC power applied.

Yellow LED NMEA input, flashes when messages are received.

Input Opto coupler input, compliant with NMEA 0183 and IEC 61162-1, voltage range approx 2 - 12 V.

1 Introduction

1.1 General

This document describes the LPU2 (2nd generation Log Processing Unit), which serves as an interconnection device between SAL speed logs, indicators and other users, such as ARPA, auto-pilots etc.

IEC61162/NMEA serial signals and how to connect cables carrying IEC61162-signals is described in document 700164

1.2 Principle of operation

The LPU2 distributes data between connected units (instruments etc.) in the SAL speed log system, as well as it transmits speed and depth data to external systems. Serial speed/depth data from one or more speed logs is received by the LPU2 and decoded to generate serial data as well as speed pulse signals. A large number of output connections are programmable.

However, a default configuration is active on delivery and shall be used whenever possible.

The unit is equipped with a power supply, able to provide power to SD indicators as well as to an Echo Sounder Display.

The LPU2 is also used for docking log calculations. The output from a Rate Of Turn gyro can be connected to the LPU2 via serial (NMEA) or analogue input. From this input and the received speed/depth signals from the speed log, the LPU2 calculates transversal speeds of both ends of the ship, which can be fed to SD4-5 docking-log indicators.

The SD4 Log Remote Control is used to access the menu system in the LPU2 as well as in connected speed logs. This SD4 shall be labeled as a Speed Log Master Display according to instructions in the SD4 chapter.

The LPU2 is equipped with an Ethernet connection (RJ45) to access the LPU2 web-interface.

This web-interface can be used to access the LPU2 menu system, display in/out going NMEA messages, display alert lists, and for other service purposes.

The LPU2 software is contained in Flash-memory, which can be updated on board from a USB memory stick or using the serial D-sub.

Note 1: The SAL T1 or T2s system does not calculate transversal speed over ground and will therefore not be used in docking log systems.

Note 2: When the LPU2 is used together with a SAL R1a (speed trough water log system), please disregard from all information referring to BT/SOG, transverse speed or docking log functionality.

This block diagram shows the general layout of the system. Data is received from the SAL T-series speed log and the Rate Of Turn gyro, alternatively a SAL R1a speed log can be used if only speed through water is required. Processing is done in the LPU2, which also serves as data distribution/interfacing unit. The exact wiring depends on each installation, depending on which displays are needed, what turn-rate gyro is used etc.

Connections to Log 1 ELC Term# Function Note 1A NMEA in 1 Connect to T-Series speed Log NMEA "A" output 1B NMEA in 1 Connect to T-Series speed Log NMEA "B" output 42A NMEA out 7 Connect to Log control NMEA "A" input 42B NMEA out 7 Connect to Log control NMEA "B" input

The NMEA in 1 connects to the NMEA out terminal 108 and 109 on the SAL T-Series speed log ELC.

4.3.1 NOTE! NMEA in 1 is not to be used if Log 1 is a SAL R1a!

NMEA in 1 is supervised by the LPU2: if there is no NMEA the relay K1 will drop.

NMEA out 7 (terminal 42) connects to the NMEA in terminal on the SAL Speed log ELC, SAL T-series and R1a.

Redundancy connections to Log 1 ELC Term# Function Note 5A NMEA in 5 Connect to Log NMEA "A" output (redundancy) 5B NMEA in 5 Connect to Log NMEA "B" output (redundancy)

SAL T-series: NMEA in 5 connects to the redundancy NMEA output (Redundant WT) in Log 1 terminal 120 and 121. This will improve the redundancy of the system. Even if the LPU2 and/or the speed over ground log are malfunctioning, at least speed trough water will still be presented on the redundancy outputs.

SAL R1a: NMEA in 5 connects to the NMEA output on the SAL R1a ELC.

NMEA in 5 is supervised by the LPU2 if there is no NMEA the relay K2 will drop.

Also refer to typical Connection diagrams in the system drawing section.

This connection (Redundant WT) has to be made when a SAL T1 or T3 system is installed to ensure the redundancy between the speed log part and the echo sounder part of the combined SAL T1 / T3 Speed log / Echo sounder system.

Connections to Log 2 ELC (option) Term# Function Note 2A NMEA in 2 Connect to Log NMEA "A" output 2B NMEA in 2 Connect to Log NMEA "B" output 43A NMEA out 8 Connect to Log control NMEA "A" input 43B NMEA out 8 Connect to Log control NMEA "B" input

A second SAL Speed Log can be connected to the LPU2. The NMEA in 2 and NMEA out 8 shall be connected to the NMEA connections of the Log 2 ELC via a twisted pair cable.

5 Setting up procedure The LPU2 has an internal menu system that can be accessed via a remote SD4 Speed Log Master Display or via the web-interface. At setup the menu system is used for:

1) changing the default setup of input- and output channels. See Menu I, N and O.

2) enter speed log transducer (TRU) position to enable docking log calculations. See Menu

S on page 28.

3) enter system type: T-Series, R1a or Dual Log. See Menu S on page 27.

4) access the internal alert list for troubleshooting. See Menu A on page 24.

The settings are stored in non-volatile memory and will therefore also be active after a reboot or power shut-down. After the setting up is finished and the system is tested, no further actions are required during normal operation.

5.1 Accessing the LPU2 Menu system

The LPU2 Menu system is accessed from an SD4 Speed Log Master Display unit or the web-interface. Here follows a short guide to access the menu system in the LPU2 via the Speed Log Master Display. (For a detailed description of the menu system in the SD4 Master Display, see document “704005 SD4 Technical description”.)

5.1.1 Reaching SD4 Menu Mode

The Mode window of the SD4 Display can be set to Menu Mode, which is used for internal settings of the display and can be used to connect to a remote unit such as the LPU2.

22 (50)

The Menu Mode is reached by pressing the Mode button for minimum 5 sec. The Mode Window will show the text “PRESS ENTER FOR MENU”. Then press the “Enter button (4th button from left)” within 5 seconds.

The Mode Window will now show the start menu in the SD4. The six buttons under the Mode Window have now got alternative functions. The alternative functions are lit in red text below relevant button.

The buttons now have the following functions:

Mode: “1st button from left”. Will inform which remote device is connected in remote mode.

Esc: “2nd button from left”. The Escape function is used in the “Remote Device menu” to escape from the menu system in a remotely connected unit (E.g. the LPU2 menu system) and step back to the local menu system in the SD4 unit.

Menu: “3rd button from left”. Is used alone, or together with the Minus (-) button, or together with the Enter button, to move in the menus as described below.

Menu button alone, will display next menu i.e. step forward on same menu level.

Menu button and Minus (-) buttons pressed simultaneously will display previous menu, i.e. step back on the same menu level.

Menu button and Enter buttons pressed simultaneously will move up one menu level, except when leaving the “Remote Device menu”. (see Esc-button)

Enter: “4th button from left” is used to store changed values or to move to sub-menus.

- + “Minus button” and “Plus button” are used to change values or status (E.g. write access OFF/ON) and /or to change device values.

Note: The Menu System will exit automatically if no button has been pressed for 5 minutes when being in the local SD4 Menu System, when connected to a remote device there is no timeout and the Escape button must be used to exit from a remotely connected device.

5.1.2 SD4 in Menu Mode

The Menu Mode in the SD4 has three “Local Menus” and one “Remote Device menu”:

• SD4 LOCAL. This is the start menu when entering the Menu Mode. If one or more other displays are remotely dimmed from the display, this menu shows a second text line were the remote dimming function can easily be turned ON/OFF.

• LP0 PROPERTIES. This menu contains sub menus for local setting up of the display.

Note: Do not turn write access ON without special training.

• LS0 REMOTE SETUP. This menu contains sub menus for setting up when the display is used as a Speed log Master Display /Remote Device for other units and displays.

Note: Do not turn write access ON without special training

• R0 REMOTE DEV. On designated Speed Log Master Displays this menu provides access to a remote device, e.g. the WTU-unit, BTU-unit or the LPU2 menu structure.

Note: Verify that the setting in SD4 menu LS7 is “R0 REMOTE ENABLED [ON]” to be able to connect to remote devices.

To connect to the menu system in the LPU2:

23 (50)

When in SD4 LOCAL (the start menu) step to R0 REMOTE DEV menu by pressing the MENU button three times.

When pressing ENTER in the R0 menu the SD4 will establish communication with all connected equipment and display them in a list of menu choices.

Press the MENU button until the LPU is displayed and press ENTER to start communicating with the LPU2.

ESC is used to step back.

Example of a menu walk in the R0 REMOTE DEV menu:
