Once started, artificial respiration should be continued rhythmically. (1) Refrain from touching the patient carelessly as a result of the accident; the first- aider could suffer from electrical shocks by himself or herself.

(A pillow may be placed under the neck.) Pull up the lower jaw to open up the airway. (To spread the airway) Pinching the patient's nose, breathe deeply and blow your breath into the patient's mouth strongly, with care to close it completely.

    Principle of operation The JLN-900 Log system is actually two more or less independent log systems, one for sensing speed over ground (SOG), Bottom Track Unit, (BTU), and the other for sensing speed through water (STW), Water Track Unit (WTU – Assy.).

    The beam travels down to the sea bed with a velocity of close to 1500 m/s. This velocity is almost constant for different frequencies. If we have a calibrated depth meter, we may have to compensate for salinity, density and temperature differences. The SOG correlation speed logs operate at 150 kHz, giving a wavelength of 10 mm.

    1 Introduction 1.1 General This document describes the Sig. Distributor, which serves as an interconnection device between speed logs, NWW-82/85 displays, indicators and other users, such as ARPA, auto- pilots etc. IEC61162/NMEA serial signals and how to connect these cables are described in document “IEC61162/NMEA0183 User Guide”.

    1.3 Principle of operation The Sig. Distributor distributes data between connected units (instruments etc.) in the 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 Sig. Distributor and decoded to generate serial data as well as speed pulse signals.

Signal Cables All cables used for signal interconnection of the Speed-log system units shall have a cross section of at least 0.5 mm with a voltage rating of at least 60 volts and be screened, either an aluminium foil screen with an inlaid, blank, stranded conductor, or tinned copper braid should be used.
  • Page 148 Do not use twisted quads or ordinary multi-pole cable, which also has somewhat twisted parts. In a twisted quad the signals in one pair will cross-couple to the other pair, because they are so close, and because one pair has no means of protecting itself from the other pair. In an ordinary multi-pole cable, the noise-cancelling properties are random or unknown i.e.
  • Page 149 Examples of proper tools for crimping end caps, and a strip of end caps Shields Grounding a screen “for safety” or “for good measure” could ruin noise immunity. Forming a ground loop will let noise slip into the system. Note: Shields shall never be connected in both ends of a signal cable, unless expressly noted. The reason for this is that the chassis (bulkhead) potential is never the same in both ends of the cable.

    WATER TRACK U is an electronic Speed and Distance Measuring Equipment board designed to be used in JLN-900 Speed Log. To create a working log the WATER TRACK U docks to a motherboard within the Sig.Processor where the measuring sensor (transducer), speed indicators and optional repeaters are also connected.

    3 Principle of Operation 3.1 Acoustic transmission/reception 3.1.1 Transmitter The transducer will send two parallel sine waves into the water. During normal operation the forward crystal (TRU cables 1 and 2) will alter between frequencies 3.800 MHz, 3.875 MHz and 3.950 MHz while the astern crystal (TRU cables 4 and 5) will alter between frequencies 4.050 MHz, 4.125 MHz and 4.200 MHz.

  • Page 235: Introduction

    General The purpose of this document is to define the most common serial messages that are used by JRC speed logs, voyage data recorders and interface units as well as specify the hardware used for serial communication. The document is intended to be used as a sub-document to operator manuals.

  • Page 236: Hardware

    Hardware The IEC 61162-1/NMEA and IEC 61162-2/NMEA standard specifies serial data links with one talker and multiple listeners, using for each talker a separate signal pair with all listeners opto-isolated. Both standards, IEC 61162-1 and IEC 61162-2, use the same serial data message definition but the hardware has some differences on the receiving side.

  • Page 237: Connection Of Cables For Serial Communication

    Connection of cables for serial communication All cables used for serial communication shall be twisted pair and properly shielded. Maximum recommended cable length is 1000 meter with a minimum cross-section area of 0.5 IEC 61162-1/NMEA uses two wires in one pair connected as signal "A" and "B" between talker and listener.

    with accurate gyro data, the two-dimensional ”dead reckoning” performed by the navigation computer can be directly compared with other position data and the angular error produced by the log can be calculated directly or indirectly. For most installations. however, this is not possible, and the following procedure is proposed: a) Place the ship on a straight course directly against current and wind so that the true transversal motion of the ship is zero.
