It is hard to tell from the phtotgraph, but the manual specifies polarity referring to pin 1 and pin 2.  Is the connector so labeled, or is this a 2.x mm "coaxial" connector in which case is the center pin positive?

From what I can tell, J10 seems to be moved from the picture that Phil has in the manual.  Note that the PCB says "J27" in the spot where Phil has it marked in the picture.  J10 seems to now by right behind where SW1 is.  It's a 4-pin connector, and this seems to correspond to what Phil has written in the manual, with pins 1&2 being 13.8V and pins 3&4 being an external 5V supply, if selected.

> Also, the power switch SW1 is missing.  Same question - where can I obtain one?  Or is there a jumper setting that makes the power switch get bypassed?  The user manual states that the power switch must be activated, so I am (again) assuming the switch is a requirement.
