Kenwood TM-D700 configuration question...

but no matter how you do it, the pins would not be right.
The GPS's with a DB9 plug into a PC set up as a DCE.
The radio is also designed to plug into a PC so it has a
DB9 configured as a DTE.  So even so, its a no-win
situation.  There has to be a tweenee to reverse the
pins.  and a DB9 to DB9 tweenee is a lot bigger than
the sub-mini...

It is frustrating, but that has always been the problem with
DB9's sexuality...

Point taken.
i certainly have no beef with supporting
compatibility with the D7 - that's a wonderful idea.

however, since the D700 does have a DB9 serial port,
and it's not uncommon to be using a GPS with
a PC via a DB9, being able to use the DB9
directly (instead of needing a KludgeKable)
would also seem to make a lot of sense.
