Title: Which USB Port for RS 232 Cable?
Post by: auster on February 19, 2020, 08:57:54 am

Just acquired the Rosetta and I'm setting it up. I want to confirm that I am getting this right. With the rear case off I see the GPS Dongle in the top centre USB port. The WIFI dongle is in the lower right port.

I now need to connect the RS 232 cable which will take the GPS signal to my Becker Mode S Transponder however the top right port is partially blocked by the GPS dongle. The lower centre port is also partially obstructed by the cable from the USB dongle but is accessible.

Do I used the lower centre USB port?

I suppose the bottom right dongle is the 1090 receiver.
Maybe you can use a cable like this to solve every problem

That would be fine, and would be identified as "Port 2"

Hi Auster,

If you are using the recommended FTDI USB to RS232 cable, you will find that if you plug it into Port 2, the plastic ‘strain relief’ on the USB plug will slot nicely onto the lower case, effectively holding the plug into the port, though you might like to gently open up the semi-circular recess slightly to ensure a good fit. If you want to put the ‘upper case cover’ back, you need to open the ‘upper part of the hole’ on the cover large enough to let the cover drop over the strain relief and slide back into place without snagging.

Regards

Peter

Thank you for the replies and they confirm my own thoughts. It will be the centre lower port (Port 2)  and yes, some gentle enlargement of the hole where the cable goes through the sliding cover will be required but is easily achieved.

Fired it up in the plane for the first time this afternoon (on the ground) and it certainly captured the satellites and a couple of planes doing circuits. An interesting learning process.
