read and write routes
GPSBabel supports the following Magellan receivers:
|Explorist 100 (with aftermarket cable)
|Explorist 200 (with aftermarket cable)
|SporTrak Map Color
|Explorist 300 (with aftermarket cable)
|SporTrak Map Pro
|SporTrak Map Topo
|Meridian (green or yellow)
The RoadMate family of products is not supported.
This format is used for both the serial protocol used on the devices with serial ports such as Map330 and Meridian and for the files stored either in either the unit's internal memory (Explorist 210, 400, 500, 600, XL) or on removable memory.
If you specify a serial port for the file (.e.g. "COM1", "/dev/ttyS0") to be read or written, GPSBabel will use serial protocol. Specifying a file, either on local filesystem or on a mounted flash card reader, will result in the file-based format being used.
Users of the Explorist generation of receivers should probably prefer to use the magellanx format over this one.
This module does not support the units that do not follow Magellan's documented communications protocols including:
Default icon name.
This option specifies the icon or waypoint type to write for each waypoint on output.
If this option is specified, its value will be used for all waypoints, not just those that do not already have descriptions. That is, this option overrides any icon description that might be in the input file.
This option has no effect on input.
Max number of comments to write (maxcmts=200).
The maxcmts option allows you to specify the number comments that will be sent to the unit.
Magellan receivers allow a maximum of 200 waypoint comments. Unfortunately, DirectRoute uses waypoint comments to provide next turn directions for navigation pop-ups and that comes from that pool of 200 comments. It is therefore sometimes convenient to limit the number of waypoint comments written to the receiver. For example, a geocacher might want to upload 400 waypoints, but only 190 with comments so that DirectRoute could provide driving directions for the next ten turns.
Numeric value of bitrate (baud=4800).
This option causes GPSBabel to use the given baud rate for serial communications. It must match the given baud rate on the receiver. The default value matches the default on the receiver, 4800.
Valid options are 1200, 2400, 4800, 9600, 19200, 57600, and 115200.
Suppress use of handshaking in name of speed.
Magellan's protocol specification strongly encourages the use of software acknowledgments on every packets. This is a simple "this is what I think I heard. If you agree that I heard it correctly, let's go to the next packet" handshake that is used to ensure the integrity of the data transfer.
Certain firmware versions have problems handling this which makes transfers unnecessarily slow. Transfers on all units at high serial speeds are also severely restricted by this process.
In controlled environments (good cables, low electrical noise, receiving from the unit, not doing donuts with the unit set to "track up" at a 150 mile scale with 500 waypoints on the screen) it is sometimes useful to release that safety belt by using the "noack" suboption.
Delete all waypoints.
This option erases all waypoints in the receiver before doing a transfer.
This is a convenient option to use in automated processes where you want to ensure the units starts with a clean state before sending waypoints to it. Using this option on transmit is a better idea than doing it on receive since the latter would erase all the waypoints before asking the unit to send all the waypoints.
