INTRODUCTION Page 11 INTRODUCTION1.1 About this installation guideThis installation guide provides information to facilitate installationof the Saab TransponderTech J4N <strong>Junction</strong> <strong>Box</strong> for the R4 (D)GPS<strong>Nav</strong>igation System.As the J4N <strong>Junction</strong> <strong>Box</strong> is intended for use with the R4 <strong>Nav</strong>igationSystem, this installation guide contains information that is relevantfor this type of installation. It is important to note that more details ofthe R4 <strong>Nav</strong>igation System installation are found in the InstallationManual for the R4 <strong>Nav</strong>igation System (part number 7000 109-009).The main part of this installation guide concerns the basic standalonenavigation configuration. Additional information related todual redundant and combined AIS/navigation installations areprovided in chapter five.1.2 Unpacking the equipmentWhen unpacking the equipment, please check that the following isincluded in the delivered package, if any parts are missing, pleasecontact the Saab TransponderTech dealer.Standard J4N package:NameQty.J4N Unit 1Mounting Screws (In plastic bag located 4inside the box)2 GENERAL INFORMATION2.1 Physical Size (mm)
GENERAL INFORMATION Page 22.2 CablingThis guide details how to mount the standard cables that are includedin the standard delivery package for the R4 <strong>Nav</strong>igation System.• R4 <strong>Nav</strong>igation Sensor Power and Data Cable, part number7000 109-011.• R4 Display Power Cable, part number 7000 108-132.• R4 Display Signal Cable, part number 7000 108-133.The basic configuration is shown below.Figure 1: Overview of R4 <strong>Nav</strong>igation System installation2.3 Power SupplyThe R4 <strong>Nav</strong>igation System (sensor and display) is designed tooperate on 24 volts DC. The nominal power used by the display andsensor is 11.2 W.The J4N <strong>Junction</strong> <strong>Box</strong> includes the required fuses for the display andnavigation sensor (2 and 1 Amperes respectively).
GENERAL INFORMATION Page 32.4 Clearance area (mm)Leave a clearance around the J4N <strong>Junction</strong> <strong>Box</strong> to facilitate serviceand installation. See recommended clearance area below.Figure 2: Recommended clearance area2.5 J4N Alarm RelayThe J4N junction box includes a relay (RE1) driven by the discretealarm output of the R4 <strong>Nav</strong>igation Sensor. The relay switch may beconnected to an audible alarm device or the ship’s alarm system. Anexternal switch for acknowledge of alarms may also be connected.The R4 <strong>Nav</strong>igation System also facilitates alarm messages andacknowledge of alarms in serial ‘NMEA’ format. Refer to the R4<strong>Nav</strong>igation System installation manual for details.2.6 J4N Circuit BoardThe components and available connections of the J4N circuit boardare shown in figure 3 and listed in table 1 below. The schematic forthe J4N circuit board is included in Appendix A of this installationguide.

MOUNTING THE BOX Page 53 MOUNTING THE BOX1. Open the lid of the J4N <strong>Junction</strong> <strong>Box</strong>2. Fix the box on an appropriate surface with the 4 supplied screws.Use the four holes that are located in each corner of the bottomplate.3. Connect the R4 <strong>Nav</strong>igation Sensor power and data cable, the R4Display power cable and the R4 Display signal cable as describedin the next section below.4. Connect cables to external equipment as required in accordancewith table 1 and indications on the J4N board. Refer to theinstallation manual for the R4 <strong>Nav</strong>igation system for detailsrelating to the external interfaces if required.5. Clamp the cables to the clamp area located on the front of the box.6. Fix the lid to the box casing7. If needed, also clamp the cable outside the box.4 CONNECTING R4 NAVIGATION SENSOR AND DISPLAY CABLES4.1 Installing the R4 <strong>Nav</strong>igation Sensor Power and Data CableConnect the R4 <strong>Nav</strong>igation Sensor power and data cable to the J4N<strong>Junction</strong> <strong>Box</strong> terminal block K2 as indicated in figure 4 below.Note: The shield of the R4 <strong>Nav</strong>igation Sensor power and data cableis connected to power supply return. It is not connected to the othershields in J4N and may be left unconnected (and properly isolated ifso required).Figure 4: Connection between J4N and the R4 <strong>Nav</strong>igation Sensor
CONNECTING R4 NAVIGATION SENSOR Page 64.2 Installing the R4 Display Power CableConnect the power cable for the R4 Display to the J4N <strong>Junction</strong> <strong>Box</strong>terminal block K1 as indicated in figure 5 below.Note: The ‘shield’ of the R4 Display power cable is not used in thecable or display. It is not connected to the other shields in J4N andmay be left unconnected.Figure 5: Power connection between J4N and the R4 Display4.3 Installing the R4 Display Signal CableConnect the signal cable for the R4 Display to the J4N <strong>Junction</strong> <strong>Box</strong>terminal block K3 as indicated in figure 6 below.Figure 6: Signal connection between J4N and the R4 Display
REDUNDANT & COMBINED AIS/NAV Page 75 REDUNDANT & COMBINED AIS/NAV INSTALLATIONS5.1 Redundant System InstallationTwo R4 <strong>Nav</strong>igation Systems may be interconnected in a ‘redundantconfiguration’ thus enabling them to automatically share databaseand navigation settings.In order to accomplish this, the Tx lines of the User 3 port on onesystem shall be connected to the Rx lines of the other system andvice versa. Refer to figure 7 for a suggested configuration using twoJ4N <strong>Junction</strong> <strong>Box</strong>es.In order to enable synchronized operation, one unit must beconfigured as ‘master’ and the other unit as ‘slave’. For furtherdetails refer to the operators manual for the R4 <strong>Nav</strong>igation System.Figure 7: Dual redundant system installation
REDUNDANT & COMBINED AIS/NAV Page 85.2 Combined AIS/<strong>Nav</strong> System InstallationThe R4 Combined AIS and <strong>Nav</strong>igation system combines the R4<strong>Nav</strong>igation System with the R4 AIS Transponder system using asingle display. A suggested installation using the J4N <strong>Junction</strong> <strong>Box</strong>and a J4 <strong>Junction</strong> <strong>Box</strong> for the AIS transponder system (part number7000 100-165) is outlined in figure 8.Figure 8: R4 Combined AIS and <strong>Nav</strong>igation System installationOptionally, the R4 Display signal cable leads can be connecteddirectly to the terminal blocks of J4 & J4N <strong>Junction</strong> <strong>Box</strong>es asfollows.
