I got in my Trueposition GPSDO's today and have one running. These units are a little bit different than the Packrat documentation. There is no second serial connector. The first three pins on the 6 pin connector are RS-232 at 9600,8,N,1 You need to jumper pins 4 and 5 to talk to the board.
The power connector is different. It is a 5 pin connector on the back of the board. 4 pins are ground and VCC is the other pin. Check with an ohm meter to make sure you connect up properly... the GND/GND/15V in the Packrat doc is backwards! Mine is running just fine on +12V... YMMV.
