Default New Oudie 2 Condor 2 cable connection

Hi Nick,

The challenge with the Oudie and similar devices is that they are using a mini-USB port to do double-duty. It connects to a PC as a USB slave, and it has TTL Serial connections for communicating with soaring variometers and Condor on a PC. The cable has 5 wires. They are very well defined for USB communications, but since TTL serial data communications are non-standard, the connections are not set in stone. Old and new Oudie 2 units and Oudie IGC units will all connect to a PC using a standard USB to mini-USB cable for flight log downloads, waypoint uploads, updates, etc. But for TTL serial data, something changed in the hardware due to lack of standardization. It isn't Naviter's fault, they buy the Oudie hardware. The change is a bummer, but well defined.

OK Thanks. Sounds non standard. I had assumed that the Oudie power and
data cable was just a 12-5V converter plus something like an FTDI USB to
TTL serial converter chip on a single PCB under the shrink wrap. In
which case as long as the USB portion was working the cables would
always be the same.

As a field service guy, many "standards" are not standard unless carved in stone.
Example, company I worked for, certain things (usually power) were consistent. So power was good, data was "wishy washy".
Certain FTDI adaptors worked, others didn't. We used a lot of boards from Rabbit that did what we needed, others didn't work.....
Sorta same spec, but different....
"It's the exact same thing, only different....".
