Help with pic interface

[tripen2]

Hi, i just purchased a futaba skysport radio4 with a blackmax pic interface. the only thing is that i can't get it to work at all. i used a pic test and it said that it was unable to open up com port 1. i was wondering if anyone could give me some simple instructions to get the controller working. i am running win2k on a compaq laptop & emachines desktop.

Thanks,
Mike

I recommend if possible that you check the interface on another computer, some of the newer laptops do not supply a high enough voltage on the serial port ot power the interface.
