Making a Cable to Go Between a GPS device and the Kenwood TH-D7

Although you can buy cables "pre-made" for connecting the GPS to the Kenwood D7, it seems to be in the spirit of ham radio... to build your own.
Hopefully these pictures will help you see what I did to get mine working.

Page 6 of Kenwood's Documentation on Connectors was very helpful. However it doesn't really say what to do with the "serial" port end of the cable. The TH-D7 manual mentions which holes are what, but obviously it can make a difference on which viewpoint (solder-side or connector-side) and whether it is a male or female port.

This cable has allowed me to connect a Magellan Meridian GPS and a Garmin etrex Legend to the D7. (NOTE: This was for use with the existing manfacturer cables that provide connections from the device to a DB-9 serial cable).

View of the front of the connector-side:

View of the top of the solder-side:

So a view from the solder-side shows the pins to be:


G = Ground
R = Red
B = Black (sometimes white)

A lot of this depends on the cable manufacturer. If for some reason it does not seem to be working, simply switch (R) and (B).

You'll notice that I used the crimp style connector for this specific cable, since the wires were large enough. On another cable that had smaller wires, I used the crimp and then soldered to make sure there was good connection.
