87APPENDIX CSpecifications and Wiring (cont.) Three optional cables are available to connect the GPSII to an external power source or interface with another unit or PC: •Cigarette Lighter Adapter— Allows connection to a 12- volt DC cigarette lighter plug. •Data Cross-Load Cable— Allows data transfer between other GARMIN GPS units. •PC Kit Data Cable— PC interface cable with 9-pin ‘D’ serial data connector.GPS II 7/23/98 4:05 PM Page 87
88APPENDIX CSpecifications and Wiring (cont.) The NMEA 0183 version 2.0 interface format is supported by the GPS II, and enables the unit to drive three NMEA devices: NMEA 0183 version 2.0 Approved sentences: GPGGA, GPGLL, GPGSA, GPGSV, GPRMB, GPRMC, GPRTE, GPWPL, GPBOD Proprietary sentences: PGRME(estimated error), PGRMM (map datum), PGRMZ (altitude), PSLIB (beacon receiver con- trol)DGPScorrections are accepted on RTCM-104 v. 2.0 format. The GARMINGBR 21 is the rec- ommended beacon receiver for use with the GPS II. Other receivers with the correct RTCM format may be used, but may not correctly display status or allow tuning control.GPS II 7/23/98 4:05 PM Page 88
89APPENDIX DExternal Antenna The GPS II’s antenna may be removed to allow attachment of an optional remote-mount GPS anten- na, such as the GARMIN GA 26. To remove the attached antenna: 1. Rotate the antenna toward the rear of the unit as shown. Note: The antenna can only be removed or installed in this position. 2. Pull the antenna gently away from the unit. 3. To install the optional external antenna, mate the BNC connector notches with the mounting posts and turn the knurled knob one-quarter turn clockwise.GPS II 7/23/98 4:05 PM Page 89
90APPENDIX EMessages The GPS II uses a flashing on-screen message indicator to alert you to important information. Whenever the message indicator appears, press PAGE to view the message page. There are two types of messages: temporary alerts and condition alerts. Temporary alerts are cleared from the message page after viewing, while condition alerts remain until the condition has been resolved. Pay careful attention to all messages for your own safety. Active WPT Can’t be Deleted—You have attempted to change the ‘active to’ or ‘active from’ waypoint. Clear the active route or GOTO before making your changes. Accuracy has been Degraded—The accuracy of the GPS II has been degraded beyond 500 meters due to poor satellite geometry or data quality. You should check other navigational sources to verify the position indicated. Already Exists—The name you are entering already exists in the GPS II’s memory. Approaching—You are one minute away from reaching a desti- nation waypoint. Battery Power is Low—Thebatteries are low and should be replaced. No DGPSPosition—Not enough data is available to compute a DGPS position. Power Down and Re-init—The GPSII cannot calculate a posi- tion due to abnormal satellite conditions. Turn the unit off, and use other means to verify the last position shown. Try the unit again later, possibly in a different location. Real Time Clock has Failed—The GPS II’s internal clock has failed. Take your unit to an authorized GARMIN dealer for repairs. Read Only Mem has Failed—The permanent memory has failed and the unit is not operable. Take your unit to an autho- rized GARMIN dealer for repairs.

Route is Full—You have attempted to add more than 30 way- points to a route. Route is not Empty—You have attempted to copy into a route already in use. Route Waypoint Can’t be Deleted—The waypoint you are trying to delete is part of a route. Delete the waypoint from the route before removing it from memory. Route Waypoint was Deleted—A route waypoint entered does not exist in the database and has been deleted from the route. RTCMInput has Failed—DGPS data being received has been lost. You are no longer receiving the beacon signal. Searching the Sky—The GPS II is in searching the sky for almanac data or the unit is in AutoLocate mode. Route Waypoint was Deleted—A route waypoint entered does not exist in the database and has been deleted from the route. RTCMInput has Failed—DGPS data being received has been lost. You are no longer receiving the beacon signal. Searching the Sky—The GPS II is in searching the sky for almanac data or the unit is in AutoLocateTM mode. Stored Data was Lost—All waypoints, routes, time, and almanac data have been lost due to battery failure, or the receiv- er’s memory has been cleared. Transfer has been Completed—The receiver is finished uploading or downloading information to the connected device. WPT Memory is Full—You have used all 250 waypoints in the GPS II. Delete unwanted waypoints to make room for new entries.GPS II 7/23/98 4:06 PM Page 91
