Can't open file: 182-9004v8.bin
Wrong File type

--- End quote ---

make sure your ftp is set up for anonymous ftp. I fought through an hour of this. Ignore the 'wrong file type' and focus on the 'cant open file'
anenni:
What a misleading error message.  :-\
I checked anonymous was working, but the file had permission problems.
thank you.

Now I succeded and the system updated from v8.0 v8.4, and it updated all three itmes with the single bin file, but copyright year passed only from 2002 to 2003, changing company from truetime to Symmetricom
year 2008 from the microsemi file description was nowhere, and after the update gps date remained indentically wrong.
they didn't even change truetime brand and copyright date on the web interface

InFoq:
Would anyone happen to know if inside the NTS-200 there might be a PPS (Pulse per second) test-point signal somewhere?  (even if mine is giving the wrong 2000 date as NTP server, at least I might get some value out of using it for accurate time-span measurement?)  thanx
b0bd:
I opened it up to have a look at that kind of possibility. It uses a Zarlink GP2021 GPS Correlator, and data sheets are readily available on the Internet.  I don't have an oscilloscope to probe the likely pins for a PPS signal though, so I just ordered a ublox GPS module and going to build a Raspberry Pi time source instead.
anenni:
I'm wondering if a linux ntpd or other daemon between nts200 and clients can correct the gps epoch correctly.

I read that there is such possibility with gpsd through a serial or usb port GPS.
