The entire instrument panel has been fired up now. Power is on and there are no smoking wires or boxes! Great.
I have the Trutrak ADI and it is taking its GPS track sginal from the garmin GNC300XL. I have spliced the RS232 output from the 300XL to the RS232 input on the ADI. That is done through shielded wire which according to the diagram is grounded only at the 300XL side and not at the Trutrak ADI side. I'm at work without the manuals so I don't have the pin numbers. But I've checked they are correct and also checked continutity.
But when I fire everything up, the Trutrak ADI has no display of track. I figure that is because I haven?t yet hooked up the GPS antenna to the 300XL so it isn?t actually giving an output yet. And of course, the bench isn?t moving so there is no track being displayed.
But I hope it is that simple! Can anyone confirm that for me?
I haven't configured the 300XL output to make sure it is talking the same language in both boxes but I thought that RS232 means they are both talking the same language.
I was hoping not to hook up the aerials and the like until I get this all back in the plane but perhaps I should do that and wheel the bench around outside to make sure it's working properly before putting it back in the plane!
What do you think?
