1.2 EL Panel removal/replacement
WARNING: Care must be taken as the EL circuit runs on very high voltages. Power should not be applied to the unit with the EL panel disconnected.
Refer to Figure 1: Raychart 420 and 425 Chartplotter exploded view and Figure 2: EL panel replacement Remove the back case (11) and disconnect the connector PCB (9A). Remove the 16 screws (7) holding in the PCB and LCD assembly (8A or 8B and 6) and remove from the facia. On PCB side below EL transformer, remove the snap rivet (5B) from the EL panel tail and unsolder the tabs. From LCD side remove snap rivet holding the EL panel (5A) to the electronic support, and gently pull the tag to remove faulty EL panel.
Fold tabs back along the replacement EL panel tail and introduce into gap between LCD and electronic support. Carefully push EL panel until EL panel tail is visible in the slot of the electronic support. Guide the EL panel tail through the PCB with a suitable tool from LCD side. Unfold the solder tabs, attach both snap rivets and solder tabs to the PCB. Reassemble unit and test EL panel is working correctly. Note: It is recommended that a new Cartridge flange seal (2) is fitted when the PCB assembly has been removed.

This document is intended to be a guide to fault finding on the RC420 and RC425. For each fault, there are suggestions and where possible, methods to confirm the fault, followed by the most likely causes. In most cases, final diagnosis will be by replacement of the suspected part. Note that a high voltage generated on the main PCB drives the EL backlight in the display. Great care should be taken not to touch this area of the PCB when the unit is operating. The PCB will be damaged, if the backlight circuit is driven without a backlight connected. During re-assembly, great care should be taken that connectors are plugged in fully, with the correct orientation, taking care not to damage any of the pins. For initial fault finding, only power needs to be connected to the unit. NMEA and GPS only need to be connected if these ports are to be tested. There are self-test options built in to the RC420 and RC425, and these are described later in this document.
Chapter 3. Raychart 420 and 425 fault finding guide
Disconnect and reconnect power. Press the power switch while listening very carefully to the unit, and use the suggestions below. This test can be repeated if there is any doubt. No sound. The unit is not starting to power up at all. Likely causes are: Faulty main PCB. Faulty connector PCB or ribbon cable connector. Power not actually reaching the unit, due to a faulty power lead, faulty power supply, or incorrect connection. Beep. Power is reaching the unit, but the power supply is not operating correctly. Faulty main PCB. The power supply is operating correctly, key backlight is on but not the LCD. Beep. The unit is operating, but the display is faulty. Display lead disconnected or damaged. Contrast set incorrectly. Faulty main PCB. Faulty Display.
The likely cause is: Contrast set incorrectly. Faulty display.
Keyboard buttons not working
Run the keyboard self-test (see RC420 and RC425 self-test) to confirm the fault. Note that a button being stuck on can give unexpected faults. For example, the power switch being stuck on will prevent the unit powering up.
No keyboard backlight
Likely fault is: Faulty main PCB
Cartridges not being read
Run the cartridge self-test (see RC420 and RC425 self-test) to confirm the fault. Likely cause of this fault is: Faulty or damaged cartridge slot. Replace main PCB.
The unit stores data in battery backed RAM. If position data, waypoints etc are all lost when the power is turned off, then the likely cause is: Faulty main PCB, probably battery. Check link JP3 is fitted.
NMEA port not working
Run the connectors self-test to confirm the fault. The likely cause is: Faulty main PCB. Faulty connector PCB/ribbon cable.
GPS port not working
No GPS 12V
The 12V supplied to the external GPS is also used internally, and so if the rest of the unit works correctly the cause is almost certainly an external short. There are two levels of protection for this. Firstly there is a short circuit protection on the power supply, and if this operates then all power will be lost and the unit will shut down unless the power switch is held down. Secondly, there is a self-resetting thermal fuse in line with the GPS power output. Once tripped, this may take a few seconds with the power off to cool down and allow the GPS supply to work correctly again.
RAM and ROM faults
These are only likely to be seen while carrying out the self-test. In both cases: Faulty main PCB.
RC420 and 425 self-test
The RC420 and 425 include self-test functions that can be used to verify correct functioning of the unit. This operating mode is obtained by powering up the unit as normal, but simultaneously holding down the ENTER key. Note: The ENTER key needs to be held down until the self-test screen is seen, as a brief press will not be sufficient. DRAM memory This will show Ok if the internal DRAM is operating correctly. If not, replace the main PCB. RT clock This will show Ok if the real time clock is operating correctly. If not, replace the main PCB. INT control This will show Ok if the interrupt control is operating correctly. If not, replace the main PCB. GPS This will show Ok if the GPS is connected and sending data. If not: a) check GPS is connected. b) check GPS power from unit. c) check GPS is transmitting data. d) check connector board. e) check main PCB. Flash checksum This will show Ok if operating correctly. If not: a) reload the code. b) replace the main PCB. Cartridge NotP if not present. Pres if present. If incorrect: a) check cartridge. b) replace the main PCB. Keyboard (run) The display shows a representation of the keypad mat. As each key is pressed, the corresponding word on the display will change to a filled box with clear wording, and a beep will be heard. When all keys have been pressed the buzzer will sound. If there is no buzzer sound replace the main PCB.
Press the CLEAR key to exit test mode and enter serial test. Serial test GPS data (GPS connected should be seen on screen) Press the CLEAR key to exit. A summary of the tests is diplayed. Press the ENTER key to restart cycle.
Resetting the system
Two types of reset are available for the Chartplotter: Power-On Reset: When you turn the display unit off, then on again, the screen reverts to the chart display with all windows cleared. Factory Reset: This resets all values back to their original factory settings.
Note: Take care - factory reset clears all Waypoint and Route databases. At power-on, the last-used values are retained for all the options, except for those listed in the following table which are reset to the factory default each time.
Item Heading Mode Alarm Contrast Level Backlight Level Power-on setting North Up ON, with last-used value Within 30-70% range, if last-used value outside this range ON at the lowest level if previously ON
To perform a factory reset: 1. Power off the unit. 2. Press and hold CLEAR whilst powering up until <Erase backup procedure> is displayed. 3. Either press CLEAR to abort Factory Reset and resume normal Power-Up or press ENTER to continue Factory Reset. 4. Press ENTER again; the unit restarts as for a first time Power Up with all values reset to their original factory settings
EL panel Pressing the up/down key will vary the Backlight level. If not: a) replace the EL panel. b) replace the main PCB.
Chapter 4. Software upgrade
The software in the RC420 or RC425 can be upgraded using a software upgrade cartridge in the cartridge port. The method is as shown below. WARNING Upgrading the software will delete all user-entered data such as waypoints etc. Main PCBs supplied as spares will already have software programmed into them as part of their test. The RC420 or RC425 can be upgraded as many times as required. The software upgrade cartridge can be used as many times as required. Removing the upgrade cartridge part way through upgrading the software (or a bad connection to the cartridge) will leave the software in the RC420 and 425 damaged, and it will not run properly. It will then be necessary to turn off the unit and have another attempt at the upgrade.
Upgrade using Nav-Chart cartridge
1. Connect Raychart 420 or Raychart 425 to a power supply. 2. Insert Nav-Chart upgrade cartridge into the cartridge port. 3. Press and hold the POWER switch for normal power on 4. The unit will start up , with a single beep. 5. Wait approximately 15 seconds while the unit initialises. 6. The version number of the upgrade software will be displayed. Confirm this corresponds to the desired upgrade version. 7. Press ENTER to commence upgrade. 8. Once Updated successfully has appeared at the bottom of the screen, remove the Nav-Chart cartridge. 9. Upgrade is complete. 10. Press ENTER to restart normal start up sequence.

1.2 Satellite Differential System
The Raystar 120 GPS Receiver utilizes a new satellite differential correction system to improve the accuracy and integrity of the basic GPS signals. Three separate compatible systems currently exist or are being developed: 1. Wide Area Augmentation System (WAAS). Developed by the Federal Aviation Administration (FAA) in the USA. 2. European Geostationary Navigation Overlay System (EGNOS). This system is being developed by a European consortium. 3. The MTSAT Satellite-Based Augmentation System (MSAS). Being developed by the Japan Civil Aviation Bureau (JCAB) for civil aviation use. The area coverage of the WAAS system is the furthest advanced so far and includes the entire United States of America but also covers large areas outside of this as shown in Figure 1-1.

Figure 1-1: WAAS Coverage Map
The combination of the WAAS, EGNOS and MSAS systems will provide global satellite based differential GPS augmentation into the future.
How it Works
The following description is based on WAAS, but the principles apply equally to the EGNOS and MSAS systems. WAAS comprises the following components: Ground Reference Stations across the USA Master Stations located at East Coast and West Coast Geostationary Satellites located above the equator The Ground Reference Stations are located at known positions and receive data continuously from GPS. The Ground Reference Stations send their data to the Master Stations which calculate the error of the GPS-received positions and generate correctional data. The corrected differential signals are then sent to the two Geostationary Satellites which broadcast the corrected data on the standard GPS frequency, making it available to the users Raystar 120 GPS Receiver. The Raystar 120 GPS Receiver uses the correctional data transmitted by the Geostationary Satellites to refine the GPS positional data for greater accuracy. WAAS is shown pictorially in Figure 1-2.
Figure 1-2: The WAAS System
Availability of the WAAS System in North America
The WAAS system is presently broadcasting and being tested for aviation use. It is expected to be certified by the FAA in 2002. During this testing and certification period, continuous service is expected, however, brief signal outages may occur as refinements and upgrades are made to the system. The status of WAAS and planned outages are available online at Raytheons website http://wwws.raytheontands.com/waas or http://www.raymarine.com
Display options are selected in System Set Up and Chart Set Up as described in Chapter 4.
The chartplotter is operated by means of the following controls: A trackpad. Six dedicated push-button (labelled) keys. On-screen pop-up menus from which options are selected. On-screen database lists which enable the editing of items. The controls are shown in Figure 1-3; they are back-lit for night-time use.

Trackpad and Cursor
The trackpad is used to move the cursor horizontally, vertically or diagonally. The cursor is the cross-hair symbol (+) which is used to select a position or item on the chart. The longer that the edge of the trackpad is pressed, the faster the cursor moves. The current cursor position is shown in the status bar at the top of the screen. The cursor is context-sensitive. Some items on the screen, such as waypoints and chart objects have information associated with them. When the cursor is placed over such objects, their information is displayed in the status bar. In addition, a function bar is displayed for certain items. For example, when the cursor is placed over a waypoint, the waypoint data is displayed in the status bar and the waypoint options function is displayed.
Note: During many operations the cursor cannot be moved around the screen, eg. whilst a function bar is displayed, the cursor is used exclusively for selection. In such cases, three rapid beeps indicate invalid action.
These keys have fixed functions. Some keys can be used in either of two ways: Press: Press the key momentarily and then release it. This method is used for most key operations. Press and hold: Press the key, keep it pressed for the period of time stated (eg. 3 seconds), then release it. When a dedicated key is pressed, one of the following occurs: 1. The associated operation is actioned, eg. change chart scale (RANGE key). 2. A pop-up menu is displayed, providing further options. 3. A set of functions is displayed. As a key is pressed, a single audio beep confirms the key action. If the key-press is not valid for the current screen or mode, three rapid beeps sound to indicate that no response is available. If required, the key beeps can be turned off as part of your set up procedure (see Chapter 4).

Moving Around the Chart
You will normally operate the chartplotter with the chart showing your vessels current location. In the default North-Up orientation (shown in the status box at the top of the display), the vessel moves in relation to the screen. You will need to reposition the chart if your vessel moves out of the area currently displayed, or if you wish to examine or place waypoints in another area. Alternatively, you can home the cursor onto the vessel using the FIND SHIP function. homing locks the vessel to the cursor and updates the display such that the chart is re-drawn so as to ensure that the vessel is always on screen, see Using FIND SHIP below. There are three ways in which you can reposition the chart: Use the trackpad to move the cursor to the edge of the chart; the chart pans across. This method is useful if the area you wish to see is just off screen. Automatically re-centre the vessel using the FIND SHIP function. Change the chart scale using the RANGE key to zoom out and in to a new area. This method is useful if the area you wish to see is some distance away.
Up menu, as described in Chapter 4. The waypoint is added to the waypoint list and named with the next available number. The edit functions can be used to change the symbol and name. When the cursor is positioned over a waypoint, the waypoint bearing and range are displayed. Waypoints can also be transferred between the chartplotter, other NMEA connected instruments or a PC, using the Waypoint Transfer functions. This section explains how to perform the following tasks using the on-screen cursor and the waypoint list: Placing a Waypoint Selecting a Waypoint Displaying Waypoint data Editing a Waypoint (symbol, name & position) Erasing a Waypoint Moving a Waypoint
Placing a Waypoint

To move a waypoint using the Waypoint List:
1. Select the waypoint using the Waypoint List as described above. The waypoint functions are displayed. 2. To edit the waypoint position proceed as previously described in Editing Waypoint Details on page 3-5.
3.3 Working with Routes
A route is made up of a series of waypoints (maximum 50). A route is made by placing a series of waypoints on the chart.
When a route is created it becomes the current route and is displayed on-screen. The current route is maintained after power-off. Only one route can be current and is displayed (if it is in the field-of-view) as solid lines connecting waypoints. If following the route, the current leg is shown as a dotted line. After a route has been created, the GOTO key can be used to follow the route. The GOTO key provides various other options as described in Section 3.4. Up to 20 routes can be saved in the route database. Any one of these can be selected from the database to be used as the current route. The current route can be edited by adding and/or moving waypoints. When a route has been saved, options are also provided to name or erase a route. This section explains how to perform the following tasks: Create a new route. Save the current route in the database. Clear the current route. Retrieve a route from the database list as the current route. Display route information, including route leg data and waypoint details. Use the database list to erase and name existing routes. Edit a route by adding, removing and moving waypoints.
To access the route function bar:
1. Press ENTER to display the primary function bar (Figure 3-16):
Figure 3-16: Primary Function Bar 2. Select ROUTES to display the first level functions (Figure 3-17):
Figure 3-17: First Level Functions 3. Select MORE to see more functions (Figure 3-18):
Figure 3-18: Second Level Functions 4. Select MORE again to return to the first level functions. 5. Press CLEAR to return to chart mode.
Creating a New Route
To cancel the Arrival alarm and go towards the next waypoint in the
route, press any key. The target becomes the origin, the next waypoint becomes the target point and the two are connected by a dotted line indicating the current leg. If the target waypoint was the subject of a GOTO, or was the last waypoint in a route, the pop-up alarm is cleared and any temporary waypoint is removed.
Alter a Route
A route can be followed from a selected waypoint (Join a route) or, if already following, advanced to the next waypoint. Also the XTE can be restarted, setting the current vessel position as the new origin. In addition, a selected waypoint can be moved as described in Section 3.2, or removed from the route as described in Section 3.3.
Join a Route
To start following the current route from a selected waypoint:
1. Move the cursor over a route waypoint until the WAYPOINT OPTIONS function is displayed (Figure 3-29):
Figure 3-29: Route Options Function 2. Press ENTER and select FOLLOW FROM HERE(Figure 3-30).
FOLLOW FROM HERE EDIT WAYPOINT REMOVE WAYPOINT MOVE WAYPOINT
Figure 3-30: Waypoint Function The vessel follows the route, using the selected waypoint as the target.
3. To return to chart mode, move the cursor away from the waypoint or press CLEAR.
Advance to a Waypoint
When following a route it is possible to advance to the next waypoint, even if the current target waypoint has not been reached.
To advance to a waypoint:
1. Press the GOTO key to display the Goto/Follow functions (Figure 3-31):
STOP FOLLOW RESTART XTE WAYPOINT ADVANCE
Figure 3-31: GOTO/Follow Functions 2. Select WAYPOINT ADVANCE. The current leg of the route is abandoned and the next waypoint becomes the target. The display is updated to show the new route leg.
Restart Cross Track Error (XTE)
Reset XTE is useful if you find yourself off track and prefer to go directly to your target, rather than get back onto the original track. Whilst following a route, or going to a target point, you can restart the XTE. This sets the XTE to zero and moves the origin to the vessels actual position.
To restart XTE:
1. Press the GOTO key. If following a route, the following functions are displayed (Figure 3-32):
Figure 3-32: GOTO Options (1) If a GOTO is in progress, the following functions are displayed (Figure 3-33):
To set the position data manually:
1. Display the Position functions as described for Sunrise/Sunset display above (Figure 3-45). 2. Select SET POSITION then either: i. VESSEL POSITION which sets the position to the current position of the vessel, or ii. SELECT POSITION which enables specific Latitude/Longitude data to be entered. Use cursor left/right to select individual characters to edit. Use cursor up/down to select the required character. iii.Press ENTER to complete, or CLEAR to abort, the change(s).
3.6 Transferring Waypoints and Routes
Waypoints and routes can be received and transmitted via NMEA, see also Chapter 5, Section 5.3, Installing the Chartplotter. The NMEA link could be to a PC, typically via a spare RS232 COM port.
Managing Database Lists
The SEND WAYPOINTS function sends all waypoints in the Waypoint List and all routes in the Route List. Sending the Waypoint List does not affect current routes. Note: Sending the Waypoint List includes waypoints in an unsaved route.
The RECEIVE WAYPOINTS function adds waypoints and routes received via NMEA to the Waypoint List and Route List. Note: Where multiple waypoints have the same position, the last waypoint sent is the only one included in the Waypoint List.
To send waypoints (and route lists):
1. From chart mode, press ENTER; the primary function bar is displayed (Figure 3-46):
Figure 3-46: Primary Function Bar 2. Using trackpad left/right, select WAYPOINTS (Figure 3-47).

Use trackpad up/down to select the appropriate options to set either a time interval or a distance interval; press up to increase the interval or down to decrease the interval. 2. Use trackpad left/right to select TRACK ON and press ENTER. The TRACK ON text changes to indicate TRACK OFF. The vessels track is displayed on-screen with a line joining the points at the selected interval.
Clearing the Current Track
The current track can be cleared from the screen.
To clear the current track:
1. Select CLEAR TRACK. The current track is cleared from the screen and memory. 2. If no further track points are to be placed, select TRACK OFF and press ENTER; the TRACK OFF text changes to indicate TRACK ON.
SmartRoute enables the latest track to be converted to a route.
To convert a track to a route:
1. Select MAKE INTO ROUTE and press ENTER. The current track is converted to a new route, with the most recently placed track point as the start of the route, ie. the track is reversed. If there is an unsaved current route on screen, the option to save the route is given, see Section 3.3, Working with Routes. 2. Check the calculated route and, in particular, that the route deviation from the original, given in the warning box, is within navigable limits.
3.8 Displaying Chart Information
Nav-Chart cards include a number of displayed objects for which data is available, eg. lights, buoys, ports or tidal data. Placing the cursor over an object displays its associated data in a pop-up box. Typical examples for Port Services and Tide Information are given below.
At detailed chart scales, placing the cursor over a port symbol enables detailed information to be displayed. Port information is indicated by the symbol. The port facilities are listed in the object information pop-up and, where available, details for each facility can be displayed. In some areas the chart shows symbols for individual facilities. These facilities and symbols are dependent upon the particular area Nav-Chart card used.
To obtain port services information:
1. Place the cursor over the port symbol for which information is required. The PORT SERVICES function, together with help text, is displayed (Figure 3-53):
Figure 3-53: Port Services Function 2. To view the port services available, press ENTER. The available services are listed on-screen in an object information pop-up (Figure 3-54):
Times of MAXimum EBB and FLOOD Tides, together with SET and DRIFT figures are shown. A separate box shows corresponding SLACK figures. These data correspond to the selected Date/Time. 3. To return to chart display, press CLEAR.
To display the Tidal Current data for a particular Date:
1. Press ENTER to select MORE OPTIONS; the SUN/MOON DATA soft keys are shown (Figure 3-62).

3.9 Man Overboard (MOB)
If a person or object is lost overboard, and you need to return to the location, use the Man Overboard (MOB) function. Note: To obtain MOB position, a valid GPS fix must be available.
To initiate the MOB procedure from the Chart display, press and hold the
GOTO key for two seconds. The system performs the following tasks automatically: Stops any GoTo or Follow operation. Selects a 1/2 nm scale (even if cartography is not available). Marks the current position as a temporary waypoint with an MOB symbol which replaces any current active waypoint and route. Displays the MOB data box, showing the bearing and range to the MOB position, the elapsed time since the MOB was initiated and COG data (Figure 3-64).
Figure 3-64: MOB Data Box Sends an MOB message, including bearing and range, to other units in the system, via NMEA.
Notes: (1) A suffix (c) to the POSition data indicates that the vessels position has been User Calibrated, see Chapter 4,Chart Set Up Parameters. (2) The RANGE key operates normally to change chart scale.
To cancel MOB, press and hold the GOTO key for 2 seconds.
The MOB symbol and data box are removed and the unit returns to normal Chart mode.
The chartplotter reports the following alarms (Table 3-1 ):
Table 3-1: Alarm Settings
Alarm Arrival Indicates The vessel has arrived at the active waypoint: it has either reached the arrival circle (the radius of which is specified) or, has reached its closest point of approach (defined by a line passing through the waypoint and perpendicular to the track). The vessel has exceeded the specified distance (maximum cross track error) from the active route leg. The vessel has drifted from its anchor position (set when the alarm was turned on) by more than the specified distance. GPS fix or Differential data has been lost for more than 30 s.
XTE Anchor No Fix
The alarms are switched on or off, and the limits set, using the Chart Set Up function via the PAGE key menu, see Chapter 4, Section 4.3, Chart Set Up Parameters. When an alarm is triggered, the alarm buzzer sounds and a pop-up box, describing the alarm, is displayed.
To silence the alarm and clear the message, press any key.
Chapter 4: Setting Up
When you have installed your system and are familiar with its basic operation, you may wish to set it up to operate according to your requirements and display information according to your preferences. This is achieved using the function controls which are displayed when the PAGE key is pressed. These settings can be changed at any time. When your preferences are set, they maintain until they are reset and are retained even when the unit is powered off. This chapter covers the following topics: System parameters and default settings. Chartplotter-specific parameters and default settings. System Set Up: controlling overall functionality. Chart Set Up: controlling the chartplotter functions, including waypoint information and vectors. GPS Set Up: displaying the Raystar 120 GPS receiver status.
The set up parameters are selected via three soft keys:
Note: The additional TRACK SET UP function is covered in Chapter 3:Operation. This section provides instructions for displaying and changing the factory default values to your preferences. The following sections list the parameters with their possible settings and describe the function of each parameter in turn.
4.2 System Set Up Parameters
To set the System default parameters:
1. From chart mode, with no function bar displayed, press the PAGE key to display the SET UP function bar (Figure 4-1):
Figure 4-1: Set Up Function Bar 2. Use trackpad left/right to highlight SYSTEM SET UP and press ENTER to display the System Set Up menu (Figure 4-2):
Figure 4-2: System Set Up Menu 3. Use trackpad up/down to move the highlight up or down the list. 4. When the required parameter is highlighted, use trackpad left/right to step through the settings. 5. When the required values have been chosen, press ENTER to implement the change and return to the set up function bar. 6. Press CLEAR to clear the function bar and return to the chart display.
Note: To return all settings to their original factory settings, perform a factory reset as described in Chapter 6. Table 4-2 lists the System menus and their options, shows the factory default settings and provides space to make a note of personal settings. Each parameter is described in the following subsections. Table 4-2: System Menu Options
Panel mount the unit as follows:
1. Check the selected location for the unit. A clear, flat area at least 7in (175mm) wide by 7in (190mm) high, with at least 3in (90mm) of clearance behind the panel, is required. 2. Using the supplied template, trace out the display unit cut-out and mark the drilling centres for the four securing holes outside of the cut-out area. 3. To provide start holes for removing the cut-out, drill four 3/8 in (10mm) holes in each opposing corner and four 1/4 in (6mm) holes for the two trunnion lug clearance slots in the cut-out area. 4. Using a suitable saw, cut along the inside edge of the cut-out line. 5. With the trunnion (yoke) and knobs removed, make sure that the unit fits in the cut-out area. 6. Drill out the four 3/16 in (5mm) securing holes as indicated on the template. It is recommended that a 1/16 in (1mm) pilot hole is drilled first. 7. Screw the studs into the vacant holes at the rear of the unit, hand tight only. 8. Place the gasket on the unit and slide the unit into the panel cut-out. 9. Secure the unit with the thumb nuts, hand tight only (Figure 5-5).

5.4 Cable Running
The minimum requirements are a power cable and a connection from the Raystar 120 GPS Receiver. Additional cables will be required if connecting to other equipment. Notes: (1) All cables should be adequately cleated and protected from physical damage and exposure to heat. Avoid running cables through bilges, doorways or close to moving objects or heat sources. (2) Where a cable passes through an exposed bulkhead or deckhead, a watertight gland or swan neck tube should be used.
The GPS connector provides power and data connections to the Raystar 120 GPS Receiver using the attached 33ft (10m) cable terminated in a moulded 6-pin connector.
Connect the GPS Receiver as follows:
1. Mount the GPS Receiver as detailed in GPS Receiver Installation on page 3. 2. Feed the GPS cable through to the rear of the chartplotter. 3. Coil up any unused cable in an appropriate safe space out of view. Do not bend the cable tighter than 4in (100mm) radius. 4. Connect the cable to the GPS connector on the rear of the chartplotter. Note: If the supplied cable is too short, use an extension cable (Part# E35003) available from your local Raytheon dealer.
