serial port cable that goes to v2

[Redline Motorsports]

Howard,

Try this:
- connect the AFM to your PC's serial port using the null-modem adapter,
- go Start->All Programs->Accessories->Communications->Hyper Terminal,
- enter any name (AFM),
- click OK,
- enter any area code and phone number (111 2223333),
- set Connect Using to COM1 (or whatever your PC's COM port is),
- click OK,
- set 38400 baud, 8 Data Bits, Parity None, 1 Stop bit, Flow Control None (from the AFM manual),
- click OK,
- now you should be in the terminal window...

In the terminal window you should see stuff being printed... if not then remove the null-modem adapter.

If it still doesn't print, shutdown HyperTerm and restart it, this time specify the other COM port (e.g. COM3), and try again with and without the null-modem adapter.

I assume this is to see if the two devices are at least communicating with or without the null modem? Once we see communication from the AFM to the PC we can then hook up to the V2 via the RJ12.

Hopefully after that we can get the trace done and move on!

I'll try this tomorrow if its this straight up.

Thanks Joe
