Hi - Thanks to all for the helpful hints which may enable me to use Tac32.
Sorry for a new posting but I had a calamity and somehow deleted all the
replies instead of moving them to my Timenuts folder!!
I converted the output to the DB25 connector on the back of the unit to
RS232 comms but it
Hi All,
I use a Z3801A with a software program called GPS Control published by BDS
Systems of Colorado and the setup works well but I have never been able to
look at or control the 3801A using Tac32.
Very recently Tac32 was upgraded to allow one to choose most of the GPS
receiver communicati

sallen key lowpass may be interesting to build,and with the GHz
bandwith op-amps avaible today, it should work great.

Hi Kevin - I have replied direct to your latest email to me and it has not
bounced back but I wonder if you have received it?
Let me have your address and I will airmail the oscillator to you pronto.

Hi Bj?m and Mike,
I have some older TU's like the 30 and these are easy to set for binary or
NMEA but the TU 60 requires a specific command 1331 and I am not savvy
enough to convert this into a meaningful @@ command if there is such a valid
command.
One would have thought the manufacturer wo
Hi All,
Thanks for the 2 prompt replies.
Tac32 does not have any facility to enter 1331 as an instruction. It has
numerous @@ commands but the TU 60 datasheets only list a small fraction of
these commands and none pertain to setting the protocol!! It is like it is
a carefully guarded secre
Hi,
I am new to timenuts.
Is anyone able to give me the binary command sentence/code to send to my
Jupiter TU-60 to change it's output from Binary to NMEA please?
I assume it has to be a binary command starting with @@ but I am unable to
find a suitable command using Tac32 control software.
My Unit comes up with an INVALID EFC +0 when switched on and never tracks
any satellites.
ALL other indicators(using GPS Control s/ware)say all is well including the
EFC!!
The EFC Volts read 19.029% or Absolute N value of 624056 so it is not near
the end of it's EFC range.
Anyone who has simila

you want to support some of the early instruents.
I use the Prologix USB box often. It appears as an serial port, and is easy
to use. As fair as I understand, the GPIB-LAN device you just telnet into.
