Cable for connecting PC to LX 7000, LX 7007, LX 8000 or LX 9000
This cable connects a PC to the small, round, panel mounted "PC connector" found on the LX7000, LX7007, LX 8000 and LX 9000 wiring harness.  It has a small round 5-pin female connector for connecting to the panel mounted "PC connector" and a DB-9f connector for connecting to a PC serial port.  This cable is included in the box with the LX7000 and LX7007.  It is probably not included in the box with the LX 8000 and LX 9000 because data is normally transferred to those units using an SD card of USB Flash Drive.

Note: This cable is designed to connect to a DB-9 9-pin RS-232 serial connector on a PC.  Most current PCs don't have 9-pin serial connectors, so a USB to serial adapter will be required.  I have tried many, and found many that didn't work at all.  I finally found one that works great with most soaring instruments.  You can see details here: FTDI Chip USB Serial Adapter.
