[Elecraft] K2 to MacLogger Connect?

[Wilfried Haeusle]

Jack,

i would suggest you using ZTerm to make a step-by-step test.
ZTerm is a Terminal Program for the Mac like Hyperterm for Windows.  
The download is free.

1. Check Keyspan Driver and Hardware:
- Disable Hardware Handshake and local echo in ZTerm. Be sure to  
choose the correct serial port.
- Shorten Pin 2 + 3 on the serial connector of the Keyspan Adapter.
- If you type into the Terminal you see the characters echoing when  
the Pin 2+3 are shortened, otherwise you have a Problem with the  
Keyspan Driver or Hardware.

2. Check connection to K2:
Follow the Section "Serial Interface Test" in the KIO2 Manual. Just  
use ZTerm instead of Hyperterm.

If this works, the problem should be within Maclogger. Unfortunately  
i don´t know anything about Maclogger.

good luck,

Wil / OE9WLJ
