Cable, PC to SN-10 Instrument Panel Connector
This cable is used to connect a PC to the instrument panel connector for the SN-10. It includes a jumper that puts the SN-10 into PC communication mode. This cable is included as a standard accessory with the SN-10.
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.
