SeaBeacon 2 System 6 OverviewTideland Signal CorporationOVERVIEWThis manual contains procedures for installing the SeaBeacon 2® System 6 frequency agile radar beacon(racon).Included in this manual are general information, maintenance instructions (including purging and repressurizing theracon), operating instructions, and a list of the contents of the racon shipping container.SeaBeacon is a registered trademark of Tideland Signal Corporation.
SeaBeacon 2 System 6General InformationTideland Signal Corporation 1CHAPTER 1GENERAL INFORMATION1.1 GENERAL DESCRIPTIONA marine radar displays a picture of all objects that reflect radar pulses within the service range of the radar.The objects displayed usually represent either hazards to navigation or guidance devices that have beendeployed to assist in course determination. When there are many returns from individual targets, the exactidentity and location of the objects displayed are difficult to interpret from the radar traces alone. Sinceconfusion at sea can cause disaster, any information that can be provided to the mariner regarding the preciseidentity and location of the displayed radar targets helps to reduce the risk of disastrous navigation errors.The SeaBeacon 2 System 6 racon provides the mariner precise navigation information in the form of a codedtrace on the radar screen that can readily be identified as specific to a particular racon. The coded traceidentifies and fixes the position of the racon with respect to other targets. When used in conjunction withnavigation charts showing the identity and location of the racon, this trace aids in the correlation of othertargets with their chart markings. Thus oriented, the mariner is able to achieve precise vessel positioning inall weather and visibility conditions.1.1.1 Functions of the SeaBeacon 2 System 6 RaconThe SeaBeacon 2 System 6 racon is an all-weather aid to marine navigation that responds to radar pulses.The racon is a transponder that receives a radar pulse from an interrogating radar and transmits a codedresponse. The presence of that response on the radar display provides the mariner precise information re-garding the identity and location of the racon because each racon can be set to produce a specific Morse codecharacter. The racon can be used to provide range and bearing information.The SeaBeacon 2 System 6 racon is frequency agile, which means that it responds at the same frequency asthe pulse from the interrogating radar. Moreover, the length of the coded racon response on the radar displayis scaled to be proportional to the interrogating radar pulsewidth. Note that one can alternatively select theSeaBeacon 2 System 6 racon to provide a fixed length response. Digital signal processing techniques andhigh speed circuitry employed in the SeaBeacon 2 System 6 racon enable it to reply to several hundredvessels in its service area.The ideal marine radar would have a narrow, well defined beam (main lobe) with energy radiating only fromthe main lobe. In practice, radar antennas radiate a small amount of energy in directions outside the mainlobe. These secondary beams are called side lobes, and if responded to, are a possible source of confusionwhen the racon is close to the interrogating radar. Should a racon respond to a side-lobe pulse from a nearbyvessel, multiple traces would be painted on the radar display, and the radar operator would not know whichof those traces represented the actual racon position relative to the vessel.
2Tideland Signal CorporationGeneral Information SeaBeacon 2 System 6At some locations, the geography of the racon installation site is such that side lobes are not a concern forracon operation because vessels are unable to approach close enough for side lobes to trigger a racon re-sponse. At other locations, side lobes have a significant effect on racon operation. A side-lobe suppressionfeatures enables the SeaBeacon 2 System 6 racon to discriminate between pulses from the main lobe andthose from the side lobes of the same radar. The racon is inhibited from responding to side-lobe pulses.Any of the pre-programmed Morse code characters beginning with a dash (shown in Table 1.1) can be usedto identify the racon. The choice of code and of code character length is made by means of an externalhandheld keypad or computer terminal.Table 1.1 Racon Codes
SeaBeacon 2 System 6 General InformationTideland Signal Corporation 31.1.2 Mechanical FeaturesThe major assemblies of the racon are a base housing/chassis assembly that contains the electronics, the X-band and S-band antennas, and a radome that provides weather protection for the antennas.The base housing is cast from marine grade aluminum. On the outside, the housing is painted with Corthaneenamel.  The radome is attached to the housing and sealed by means of an airtight O-ring. This arrangementprotects the internal assemblies from saltwater intrustion. Sealed cable connectors assure submersibility atwater depths up to 10 meters (35 ft).The reliability of the circuit interconnections is enhanced by the use of a printed circuit backplane andconnectors with gold-plated contacts.The radome is made from gray polycarbonate structural foam, a material that is highly transparent to micro-wave energy and remains stable under ultraviolet radiation. The exterior of the radome is coated to seal thestructural foam and painted with polyurethane enamel.1.1.3 Input Power RequirementsThe SeaBeacon 2 System 6 racon requires an input voltage of 9 to 36 volts DC that can be supplied byseveral types of DC power sources. An AC-powered battery charger and storage battery combination is areliable method of obtaining unlimited power to operate the racon. In remote locations where AC mainspower is not available, the racon can be powered by a photovoltaic generator coupled to a 12 volt or 24 voltbattery. Under all conditions, the effective source impedance of the voltage supply must be less than 0.05Ohm.Under limited-power conditions, racon power consumption becomes an important factor. The power man-agement feature of the SeaBeacon 2 System 6 racon ensures minimum power consumption.

CHAPTER 2INSTALLATION2.1 INITIAL INSPECTIONInitial inspection of a SeaBeacon 2 System 6 racon is a three step process: receiving, unpacking, and visuallyinspecting the racon.Receiving:When the SeaBeacon 2 System 6 racon arrives, make note of any physical damage to the exterior ofthe shipping container. Exterior damage may be the only clue to possible interior damage caused byrough handling in shipment.Unpacking:Unpack the racon carefully without damaging the shipping container. The container has customdesigned cavities that conform to the shape of the racon. Save it for future use in shipping the racon.Visual Inspection:After the unit is unpacked, visually inspect the racon for obvious damage. Check that all associatedhardware is accounted for and damage free.2.2 INSTALLATION MATERIALS SUPPLIEDTable 2.1 identifies the contents of the shipping container. All materials required for normal installation areincluded in the shipping container. At some sites there may be a need for a mechanical lifting device toposition and hold the racon in place prior to installing the mounting hardware.SeaBeacon 2 System 6 InstallationTideland Signal Corporation 5
Installation SeaBeacon 2 System 66Tideland Signal Corporation2.3 INSTALLATION CONSIDERATIONSIn planning the installation of a SeaBeacon 2 System 6  racon, consider the requirements for level installa-tion, proper orientation of the racon, and possible obstructions to its operation.NOTE:All pre-installation adjustments are performed in the factory. Further adjustments prior to installationin the field are not necessary.Table 2.1 Contents of the SeaBeacon 2 System 6 Shipping ContainerQTY NAME TIDELANDPARTNUMBER PURPOSE1SeaBeacon 2 System 6 Racon (GMU) X+S-Band 070.1011-101Power & Data Cable Assembly, Ext. 510.1235-001External Cable Tag 304.1565-00 Identifies conductorcolor and signal forconnector pins.1 4 6 9              12 3 4Leveling/Mounting Kit consisting of:M10 X 1.5 X 100mm Hex Head BoltM10 Split Lock WasherM10 Flat WasherM10 X 1.5 Hex NutM10 External Star Lock WasherM10 X 1.5 Hex Nylok Nut901.1042-00211.1467-00233.1043-00230.1034-00221.1064-00232.1008-00221.1055-00Secures racon tomounting surface.1SeaBeacon 2 System 6 RaconInstallation Manual 011.1181-00 Installationinstructions.
SeaBeacon 2 System 6 InstallationTideland Signal Corporation 7Site:The racon must be leveled. For fixed mounting surfaces, install the racon within 1 degree of truevertical. For installation on buoys, just mount the racon upright.For best results, locate the racon as high as practical in order to provide a clear line-of-sight pathbetween the racon and the marine radar. In general, the higher the racon is mounted, the better is itsuseful range.For example, a ship’s radar antenna is 15 meters (50 ft) above water, and the highest point of land thevessel is approaching is 91 meters (300 ft) resulting in a nominal radar range of approximately 28nautical miles.[]TRTXNM HHR+= 08.2R is in Nautical MilesHTX and HTR are Heights in MetersFor more information about racon range estimates, please see the IALA publication “Guidelines onRacon Range Performance”, December 1999.Orientation:The racon must be mounted vertically. The orientation arrows on the lift ring and housing (oppositethe connectors) must align and should point seaward or toward the longest range of the traffic servicearea.Record of Obstruction:Create a record of the installation that notes the date of installation and any obstructions that existbetween the racon and the sea lanes where ship traffic of interest will pass. Retain this record andrefer to it periodically to determine whether any new construction is interfering with racon perfor-mance to the extent that relocation may be advisable.
Installation SeaBeacon 2 System 68Tideland Signal CorporationWARNINGTo avoid personal injury, use care in standing on theracon support structure. The footing on the supportstructure may be covered with slippery marine growth.DO NOT use the racon as a step-up ladder. Thehousing will not support your weight.2.4 MECHANICAL MOUNTING PROCEDURESThe racon can be mounted either on a flat and level surface with 4-hole mounting or on a non-level or non-flat surface with 3-hole mounting; however, the racon itself must be leveled. If the mounting surface is level,follow the procedure below to mount the racon. If the mounting surface is not level, follow the alternateprocedure to non-level mounting surfaces.Level Mounting Surface:Follow the steps below to mount a racon onto a  flat and level surface. Refer to Figures 2.1 and 2.2  formounting details and mounting hardware.1. Locate the leveling/mounting kit (P.N. 901.1042-00). See Figure 2.2 to identify the mounting hard-ware required for level mounting.2. Drill four 13 mm (0.5 in) diameter holes in the mounting surface (pedestal or flange) to which theracon will be affixed.

Installation SeaBeacon 2 System 614 Tideland Signal Corporation2.5 ELECTRICAL CONNECTIONS2.5.1 DC Power Cable LimitationsThe SeaBeacon 2 System 6 racon must have a minimum 9 VDC input at the connector terminals in the raconbase housing to operate properly. This means there is a practical limit on the total cable run from the batteryto the racon, especially for 12 VDC batteries.The power cable run consists of two sections of cable: the cable P.N. 510.1235-00 (or -01) that ships withthe racon, and a second cable between the racon junction box or distribution box and the battery, whoselength and size is usually determined by the installer.2.5.1.1 12 VDC Power SystemThe Tideland cable uses #12 AWG copper wire for power conductors. Assuming a worst case peak instanta-neous current of 15A in the cable, and a loaded battery voltage of 11.0 VDC (based on a nearly dischargedbattery), the overall allowable cabling loss is 2.0 V. Assuming a safety factor of 0.3 V for miscellaneouslosses in field connections, the design loss in all of the copper wiring must be limited to 1.7 VDC at 15A.The 16 foot Tideland cable P.N. 510.1235-00 will contribute a loss of 0.78 V. The remaining allowable lossin the other cable is then:1.7 - 0.78 = 0.92 VThe 50 foot version of the Tideland supplied cable (P.N. 510.1235-01) will contribute a loss of  2.43 V.Therefore, the 50 foot cable is not recommended at all for use in installations with 12 VDC batteries. Table2.2 shows the cable limitations for connecting a 12 VDC battery to the racon junction box.

Installation SeaBeacon 2 System 616 Tideland Signal Corporation22.0 - 4.0 = 18.0 VDCAt 18 VDC, the worst case peak instantaneous current in the cable is 10A. The 16 foot Tideland cable P.N.510.1235-00 will contribute a loss of 0.52 V. The 50 foot version of the Tideland cable P.N. 510.1235-01will contribute a loss of 1.62 V. The remaining allowable loss in the other cable is then:3.7 - 0.52 = 3.18 V, when the 16 foot cable is used, and3.7 - 1.62 = 2.08 V, when the 50 foot cable is usedTable 2.3 shows the cable limitations for connecting a 24 VDC battery to the racon junction box.2.5.1.2 24 VDC Power SystemAssuming a loaded battery voltage of  22.0 VDC (based on a nearly discharged battery), the overall theoreti-cal allowable cabling loss is 13.0 V. However, Tideland recommends limiting the practical overall cablinglosses to 4.0 V maximum for optimum operation. Assuming a safety factor of 0.3 V for miscellaneous lossesin field connections, the design loss in all of the copper wiring must be limited to 3.7 VDC. The minimuminput voltage at the base housing of the racon is then approximately:
SeaBeacon 2 System 6 InstallationTideland Signal Corporation 17Tideland racon junction or distribution boxes can accept a maximum wire size of #10 AWG or 6 mm2 sq. Ifconductors larger than this must be used for the battery cable, an intermediate junction box will be requiredto make the wiring transition to the Tideland junction box or distribution box.Table 2.3 Cable Limitations for 24 VDC Battery SystemsWIRE SIZE RESISTIVITY,OHM/1000FEETMAXIMUM LENGTH OF CABLE (feet)16 FT.

InstallationSeaBeacon 2 System 618 Tideland Signal Corporation2.5.2 Electrical Connection ProcedureElectrical connections required for power, control, status, and communications are shown in Figures 2.6 and2.9. If the installation requires power and data connection arrangements other than through the junction boxshown in Figure 2.6 or the distribution box shown in Figure 2.9, refer to Figure 2.4 for connection assign-ments. The Tideland power and data cable has pig-tail leads on one end, which are adaptable to any otherconnector.The SeaBeacon 2 System 6 racon is designed to have the negative (-) side of the power supply connected tothe negative (-) side of the battery which should be earth grounded.The following steps explain how to make connections when using Tideland junction boxes or distributionboxes.1. The standard junction box for the SeaBeacon 2 System 6 racon is the JB-5R Junction Box (P.N.630.1169-00). If the racon is to be used with blanking (Inhibit) or communications, however, itrequires the DB-5P Distribution Box (P.N. 630.1187-06). Determine which box is to be used with thesystem and refer to the associated figures and connection tables on the following pages. For the JB-5R box, refer to the block diagram in Figure 2.5 and to the block diagram in Figure 2.8 and thewiring diagram in Figure 2.9.2. Locate the appropriate box and mount it. See Figure 2.7 for JB-5R mounting dimensions and Figure2.10 for DB-5P mounting dimensions.NOTE: The power and data cable supplied (P.N. 510.1235-00) is 4.5 meters (15 ft) long.3. Pass the racon power and data cable through the appropriate gland and terminate the wires as shownin the appropriate figures and tables (Figure 2.6 and Table 2.2 for the JB-5R, or Figure 2.9 and Tables2.3 through 2.6 for the DB-5P). For the JB-5R box, install the crimp-on terminals provided beforeterminating the wires to the terminal strip. Tighten the gland nut securely.4. Connect the DC power line and all other lines to options according to the wiring diagram for the boxused. For the installation of the blanking or the GO/NO GO option, refer to Section 2.6. If possible,install a disconnect switch for the DC power line at the power source. With a disconnect switchinstalled, turn the power off. If a disconnect switch cannot be installed, use care when connecting thepower and data cable to the racon. Do not proceed to step 5 until the racon is ready to be energized.Securely tighten all gland nuts.5. Remove the dust cap from the bulkhead connector (J-1) on the racon (see Figure 2.1). Retain the dustcap for later use if the racon should have to be shipped. Connect cable connector P-1 (Figure 2.4) tothe bulkhead connector. Mate the connectors and apply moderate force until they seat. There will besome resistance because the connection is designed to be watertight.
SeaBeacon 2 System 6 InstallationTideland Signal Corporation 19While pushing cable connector P-1 into place, rotate the locking ring clockwise. Hand-tighten the lockingring until it is flush with the base of J-1.6. If you turned the power off in step 4 above, now turn it on. At this point, the racon is ready to oper-ate.NOTE:   The power input to the racon is completely protected internally from reverse polarity, high voltage, power surges, lightning, and AC ripple.It is imperative that the grounding strap has a secure connection to earth ground.A suitable connection that can sustain adverse effects from the environment (temperature, humidity, vibra-tion, shock, and salt spray) is required.The resistance from the metal terminal at the base must be less than 1 Ohm to earth ground.CAUTIONThe Ground Strap must securely connect to a earth groundfor lightning protection.

SeaBeacon 2 System 6 InstallationTideland Signal Corporation 312.6 BLANKING AND STATUS DISPLAY2.6.1 Inhibiting Racon Response to a Fixed RadarBlanking is a useful function when there are fixed radars within the SeaBeacon 2 System 6 racon service areafrom which a racon response would serve no purpose. A detrimental effect would be additional powerconsumption. The SeaBeacon 2 System 6 racon can be inhibited from responding to fixed radars by connect-ing a blanking control signal from the fixed radar to the racon. The blanking signal must have the character-istics shown in Figure 2.11.The blanking signal must be connected to the SeaBeacon 2 System 6 racon on the INHIBIT (+) and theINHIBIT (-) lines of the power and data cable (P.N. 510.1235-00). The blanking circuit in the racon uses ahigh speed optocoupler and is functionally equivalent to the circuit in Figure 2.12.If a single radar is in the service area, either the JB-5R junction box or the DB-5P distribution box may beused. In either case, the external blanking signal from the radar is connected to the Inhibit opto-isolator ofthe SeaBeacon 2 System 6 racon. If two radars are in the service area (for example, a nearby installation has aX-band and S-band radar) the DB-5P distribution box must be used. The external blanking signals must berouted via the N Type connectors. Either radar may be connected to either N Type connector. The driverrequirements are the same for both radars.Figure 2.11 Blanking Pulse CharacteristicsFigure 2.12 Functionally Equivalent Blanking Circuit
SeaBeacon 2 System 6 OperationTideland Signal Corporation 322.6.2 Status DisplayThe status display lines (GO/NO GO + and -) provide a means of continuously monitoring whether or notthe racon is functional. Figure 2.13 shows a functionally equivalent circuit along with a suggested methodfor implementing the GO/NO GO function. The circuit can switch an outside current source of 1.5 mA orless. This low current drives a transistor switch in the distribution box.The polarity or signal sense that the SeaBeacon 2 System 6 racon provides is user selectable. The opto-isolator is normally turned on only if there is a racon malfunction.  This method minimizes supply current.Use of the DB-5P junction box is encouraged.The DB-5P distribution junction box contains a GO/NO GO relay with a form C contact output. Either anormally closed or a normally open contact, rated at 1 Amp/120 Volt maximum AC or DC, may be selected.Figure 2.13  The GO/NO GO Circuit

SeaBeacon 2 System 6 OperationTideland Signal Corporation 35CHAPTER 3OPERATION3.1 INTRODUCTIONThe SeaBeacon 2 System 6 racon has been configured at the factory with the standard settings listed in Table3.1 unless otherwise specified at time of purchase.The user interface of the SeaBeacon 2 System 6 racon allows the user to change the operating characteristicsof the racon to meet his particular requirements. Also, the user can command the racon to perform internaltests for maintenance and diagnostic purposes.The user communicates with the racon by using an external terminal to enable features or specify operatingvalues to the racon. The external terminal can be any ANSI compatible ASCII terminal, including computersrunning terminal emulation programs such as HYPERTERM.The external terminal allows you to test the SeaBeacon 2 System 6 racon in the field or shop without openingthe racon. When you connect the external terminal to the racon, turn it on, and set it for terminal mode, thepower management system completes its cycle and then goes into the Listen state. This activates the termi-nal. The racon will remain in the Listen state until the keypad or keyboard is turned off and power manage-ment resumes or until the racon times out due to a lack of keyboard activity (after 5 minutes).3.2 SETUP PROCEDURES3.2.1 External Computer Terminal3.2.1.1 Connecting a Computer Terminal to the SeaBeacon 2 System 6 RaconA cable with a DB25 connector (to connect to the racon) and an appropriate connector on the other end forthe user’s terminal (typically a 9- or 25-pin connector) is required to connect the computer terminal to theracon.

SeaBeacon 2 System 6 OperationTideland Signal Corporation 433.4 PURGING AND REPRESSURIZINGThe SeaBeacon 2 System 6 racon is normally pressurized at the factory to prevent moisture intrusion. Onrequest, Tideland will provide unpressurized racons.This section defines maintenance requirements for preventing moisture intrustion over the life of a pressur-ized or unpressurized racon.3.4.1 SeaBeacon 2 System 6 Racon Without PressurizationAn unpressurized racon is shipped from the factory with two packets of desiccant inside the racon housing.This desiccant will protect the racon from moisture for at least one year.3.4.2 SeaBeacon 2 System 6 Racon With PressurizationThe racon base housing/chassis assembly is pressurized at the factory with pure dry nitrogen to 35 6 5 kPa(5 61 psig) to protect the internal electronic components from moisture intrustion.The racon should be purged and repressurized periodically to ensure sufficient gas pressure. The requiredpurge kit is available as Tideland P.N. 901.1058-00. To perform the purge procedure, you should have acylinder of dry nitrogen gas, an adjustable pressure reducing valve, and adapters to connect the pressurereducing valve to the gas cylinder.The pressure reducing valve should have an inlet pressure range of 21,000 kPa (3000 psig) and a maximumoutlet pressure of 205 kPa (30 psig). The reducing valve should be equipped with inlet and outlet pressuregauges of the appropriate ranges.  The connection to the purge manifold is 0.25 inch NPT male thread.Figure 3.2 depicts the connection of the purging equipment to the racon.Perform the following purging and repressurizing procedure once a year to ensure that the racon is suffi-ciently pressurized.
Operation SeaBeacon 2 System 644 Tideland Signal Corporation3.4.3 Purging Operation1. Assemble the purge kit components, the pressure reducing valve, and the gas cylinder as shown inFigure 3.1. Do not connect the manifold outlet hose to the adaptor fitting at this time.2. Remove the cap covering the purge inlet fitting and carefully connect the adaptor fitting to the purgeinlet.3. Turn the adjustment know on the pressure reducing valve to the minimum setting. Slowly open thegas cylinder valve until the inlet pressure gauge stops rising; then fully open the cylinder valve. Openthe isolation valve on the purge manifold. Slowly increase the outlet pressure of the reducing valveuntil gas begins to escape from the manifold outlet hose. Allow the gas to flow at this slow rate forabout 15 seconds. Then connect the hose to the adaptor fitting, which was connected to purge inlet instep 2 above. Increase the outlet pressure from the reducing valve to 35 kPa (5 psig), measured by theoutlet pressure gauge on the reducing valve.CAUTIONWhile purging the racon, do not allow the pressureindicated on the manifold pressure gauge to exceed138 kPa (20 psig). Internal pressure of more than 138kPa (20 psig) could damage the racon housing andprevent the housing from sealing properly.NOTE:The purge manifold is equipped with a relief valve to warn the operator of excessive pressure. If therelief valve starts venting gas, close the isolation valve and check the manifold pressure gauge. Therelief valve provides only a warning of excessive pressure. It cannot prevent damage to the racon isyou apply excessive inlet pressure to the purge manifold.4. Using the vent valve tool (P.N. 297.1010-00), loosen the plug on the purge outlet (at the top of theradome) until you can hear the hiss of escaping gas.5. Allow the gas to flow into the racon at a minimal rate and to vent from the purge outlet for 5 min-utes. The purge gas volume is 10.1 liters for the X+S-band GMU model.6. Close the purge outlet and secure it with the vent valve tool.

Operation SeaBeacon 2 System 646 Tideland Signal Corporation3.4.4 Repressurizing1. Increase the outlet pressure of the reducing valve to 35 kPa (5 psig). Allow the racon to pressurizeuntil the manifold pressure gauge indicates 3 6 5 kPa (5 61 psig). Close the manifold isolationvalve and check the pressure on the manifold gauge. If the pressure is too low, open the isolationvalve and allow gas to flow for 1 minute. Then close the isolation valve and check again. Repeatuntil the pressure on the manifold gauge reads 3 6 5 kPa (5 61 psig).2. Close the manifold isolation valve and the gas cylinder valve, and set the pressure reducing valve atthe minimum setting. Disconnect the manifold outlet hose from the adaptor on the purge inlet fitting.This connection must be broken quickly to minimize the amount of gas escaping from the racon.Remove the adaptor fitting from the purge fitting. This connection must also be broken rapidly tominimize escaping gas.3. Disconnect and store the purge kit. Secure the gas cylinder by removing the pressure reducing valveand replacing the protective cap.
