In one conversion, Bishop had to cut 1,000 waypoints from 16 characters (which Raymarine allows) to 10 characters (the maximum for Garmin). There is some nuance to the export-import process. If you can save the old data on a card that is supported by the new device-meaning you have a card reader for it-the conversion process is pretty straightforward: Import the file, fix it if needed, and then export the file in the desired format. All of the waypoint data is then put into a spreadsheet-like format on the PC.Īndren gives you a wide range of options for importing this data-Furuno, Garmin, Maptech, Northstar, Raymarine (by series), Simrad, GPX, etc. You click Get Waypoints, and the PC does just that, again and again. With the wiring completed, and the old chartplotter (Garmin 215, in this case) set to Data Transfer, you simply go to the Andren Tools menu, select Upload Download GPS, and select Garmin. You also will need a power supply to run the GPS. Once the wires have been identified, you interface them to the corresponding wires on your chartplotter. In this case, the red serial cable wire is the receive data (pin 2), the orange wire is send data (pin 3), and the green wire is data ground (pin 5).
To carry out an NMEA transfer, you need a good quality USB-to-serial adapter and a serial data cable with the critical wires stripped and identified. If data cards and readers are no longer available for your older system, you can usually download the waypoints using the chartplotters NMEA 0183 outputs. The first involves doing the conversion with Andren and loading the waypoints into the new system using data cards.
There are two paths you can take when migrating waypoints from one system to another. The software is so versatile that it even can be used to transfer the waypoints from an old Loran receiver (remember those?) to a new GPS. There are several ways to do this, but Bishop found that one of the most convenient ways to transfer waypoints was using Andren software on a PC computer.
Not long ago, one of our marine electronics testers, Bill Bishop, was faced with the task of transferring the waypoints from an ancient Garmin 215 chartplotter to a newly installed Garmin 7215. Photos courtesy of Andren bottom photo by Bill Bishop
