I sent this message to Trimble, but no answer yet.  Is anyone using
the Placer 400 and having similar problems?

Thanks,
John

Hello,

I'm running a Placer GPS400 gps unit with the latest version of GPSSK.EXE
from your web site (GPSSK V2.04).  I'm using a small 10V 500ma power 
supply for the main power and a 9V battery for backup power.  I've measured 
the voltage on the power connector that attaches to the Placer 400 and the
voltages are OK.

I used the DOS mode command:  mode com1:4800,n,8,1 prior to running
GPSSK, and this reduced the number of garbled lines that the PC
receives.

The unit does get the correct coordinates most of the time but also
reports:

Battery Back-Up Failed
Battery Powered Timer/Clock Fault

Is there an internal Lithium battery?  If necessary, how can I
get this unit repaired?
