As I keep trying to stress, it not a matter of a specific receiver,
but the data format that the receiver outputs.  The Trimble NetR5 was
the first one that could use Trimble's new "RT27" data payload.
This would show up as record 27 in a .tgd file (exactly like a .dat
file except the data is in the full GNSS record 27 instead of the
GPS/SBAS-only record 17) or as record 0x57-6 in Trimble's stream format.
To read these RT27 records you need at least teqc version 2008Nov4 --
or any later version will also work.  There have been incremental tweaks
to reading RT27 since 2008Nov4, so the best option is just to get
the latest available version.  The link above is the one for Windows;
for all supported systems, see:

http://facility.unavco.org/software/teqc/teqc.html#executables

For completeness, it's worth mentioning (again) that if you are
doing a download, you will probably not be getting .dat/.tgd files
directly, but instead a .r00/.t00/.t01/.t02 depending on which Trimble
receiver you are using (going back to the old series 4000 units).
For the NetR5, it should be a .t01.  To convert any of these
into .dat/.tgd, use Trimble's `runpkr00`, and UNAVCO has executables
for Windows, Linux, Solaris Sparc and Solaris x86 on-line:

http://facility.unavco.org/software/download_transfer/trimble/trimble.html

Get version 5.16 (all executables) and it should work on any
.r00/.t00/.t01/.t02 file from any Trimble receiver.

Now converting .r00/.t00/.t01/.t02 to .dat/.tgd with `runpkr00`,
include a '-g' option to get the most complete version.  If the
.t00/.t01/.t02 has RT27 in it, then you'll end up with a .tgd file;
if not, i.e. the .r00/.t00/.t01/.t02 has RT17, then you'll end up
with a .dat file.  If you don't use '-g', you'll always end up with
a .dat file with RT17 data. (As far as teqc is concerned, treat .dat
and .tgd files the same way -- except you'll be able to get GLONASS
data out of .tgd -- assuming the receiver/antenna being used was
tracking GLONASS.)

Hope that helps.

cheers,
