That's the normal pattern.

You really need that connection if you want to understand what is going on.  
Can you get a friend to help?  My setup is currently working without a 
RS422-RS232 converter.  I did have troubles a while ago with a different PC.  
I assume the problem was poor grounding.

The "No GPS" LED on my REF-1 blinks when I disconnect the antenna and goes on 
solid if I move the antenna to a crappy position (or for a while after I 
reconnect the antenna).  The same LED on the REF-0 goes on after a short 
delay - no blinking.

These are my opinions.  I hate spam.
