Dear David,

Yes, I bought the same unit as you. I will come back to you tomorrow with some serial number information. 

I am starting to think my serial cable is bad. I can't connect to any of my two units! Both of them have been locked to GPS signals perfectly. Shame on me… I just returned from CENAM and I am very, very tired. If you are able to connect to your unit, please advise. None of the combinations I got in past emails worked. It must be cable or serial port, or blame it on the operator. I will update this thread with more information tomorrow. 

I will be getting new toys to play around during the weekend. I will comment in a separate thread as soon as they are delivered to me. I wish to correspond with someone having the same equipment nowadays ; )


Best regards and good night!
