Gerald,

Try to order the SEP Sensor without the electronics. Then just use Larry's
amplifier and A/D converter and WinSDR software. That would work out just
fine.

Thank you for your excellent reply and description of the SEP sensor.  I am
sure that it will be helpful to interested  parties in our PSN group here in
the U.S.

 

Please let me clarify my questions.  Many of the amateur seismology people
here are using Larry Cochran's A/D Amp box from Webtronics in Redwood City,
California.  We are also using his WinSDR and WinQuake software packages for
display and analysis.

 

Many of us are very interested in the SEP Sensor, but wish it to be
compatible with our present equipment and software setup.  We realize that
it is designed, along with your A/D Amp box, to be used with Amaseis. But,
we observe that the connection from the magnet/coil goes directly into your
A/D Amp box and from there to the computer with AmaSeis software.

 

I appears obvious to me that the signal from the magnet/coil going to your
A/D box  would be a simple analog signal.  That is exactly what we use in
our setups.  Therefore, why couldn't that signal be plugged directly into
our A/D Amp box with the RCA plug?  We would not use your box and software,
unless we chose to use it, and would the option of either type connection.

 

Secondly, cost and shipping of the SEP is a major factor!  The sensor
obviously is of outstanding construction.  However, since the majority of
our users here are not educational institutions or commercial companies, we
do not have unlimited funds.  Many of us are retired and enjoy seismology as
a hobby.  Those of us that have the ability, construct our own sensors from
whatever materials we can.  

 

Months ago, I asked and was told that you were investigating the ability of
paying for the SEP with credit cards.  I have never heard anymore or see
anything on your webpage indicating that is possible.  Furthermore, we need
to know what the estimated shipping costs might be to the U.S.  

 

Believe me!  There IS an interest in the SEP sensor here in the U.S.

 

Best regards,

Gerald Payton.

Here's the Answer for the technical question:

 

The Seismometer electronics were designed with Amaseis in mind. An extra
option for the SEP Seismometer was added to Amaseis, however, the data
format is fairly standard over the 9600 baud serial link. The protocol
transmits each sampled value (every 1/20th of a second) as an ASCII string,
i.e. -32767 to +32767 followed by a CR and LF. Hence, the data could
certainly be captured and analyzed without Amaseis.

 

Hope this helps.

 

 

Kind Regards
