NAME

gpstrans - communicate with Garmin GPS receiver

SYNOPOSIS

gpstrans [ options ] [ file ]

DESCRIPTION

gpstrans allows the user with a Garmin GPS receiver to upload and download waypoints, routes, almanacs (satellite orbital elements) and trackroutes. If file is not supplied, data will be read from stdin (-ux switch) or written to stdout (-dx switch).

OPTIONS

-pport
set serial I/O device
-s
set datum, format, offset, and device interactively, and save them in $HOME/.gpstrans.
-i
identify connected GPS
-o
turn off GPS device
-t
get time from GPS
-ts
get time from GPS and set system time on host
-dx
download data indicated by x: r=route, t=track, w=waypoint, a=almanac
-m
With -dt, downloads track data in the format which can be displayed by Mayko mXmap(1). With -dr or -ur, downloads or uploads route data in a format compatible with Mayko mXmap.
-ux
upload data indicated by x: r=route, t=track, w=waypoint, a=almanac
-v
print program version.
--verbose
Increase verbosity.
--debug
Add debug printouts.
--help
Print help text.

CONNECTION

For a DB-25 connector, you may need to connect pin 4, 5 and 6, 8, 20 together. This sets handshake signals so that your workstation can use the serial port to communicate with the GPS.
 
                         1     ### #####
                         o o o # # # o # o o o o o
                          o o o o o o # o o o o o
 

Connect the Garmin cable as follows:

 
                           2 3       7
                         o o o o o o o o o o o o o
                          o o o o o o o o o o o o
 
         Pin 2 goes to DATA IN  (White)
         Pin 3 goes to DATA OUT (Brown)
         Pin 7 goes to GROUND   (Black)
 

If it doesn't work in this way, try exchanging pins 2 and 3 at the connector.

The circular connector on a Garmin GPS II receiver can be wired to a DB-9 connector as follows:

         DB-9 pin 2 goes to circular connector pin 2
         DB-9 pin 3 goes to circular connector pin 4
         DB-9 pin 5 goes to circular connector pin 3
         other pins are not connected
 
         (Note: the pin numbers for the circular connector are 
         arbitrary, and may not match the `official' numbers.)
 


 If your plug is more recent than the one above (ex: etrex) then you need DB-9 or DB-25 to be connected to your Garmin GPS like this:


                          


                                       _____,-----,
                            POWER(+)  |     |     |
                           groove --> |=====|     |_____

For testing, you might try setting the GPS to NMEA-Output and using a terminal emulator program like Kermit. The GPS will send a data record every 2 seconds. As long as you don't see any data on your computer, gpstrans won't work.

After finishing the test, be sure to set your GPS receiver to GRMN/GRMN.

ENVIRONMENT

GPSDEV
Serial I/O device (overrides contents of $HOME/.gpstrans, and is overridden by -p switch).

FILES

$HOME/.gpstrans
Has user preferences for datum, format, offset, and serial I/O device (see -s switch, above).
