Good Morning to All:

I sent an email to Rockwave in the UK ( http://www.rockwave.co.uk/ ) about 
their HS-3 Sensor and received the following reply.  I found the reply quite 
interesting and informative.  I thought that I would share it with everyone. 
some of you may be thinking about buying the HS-3.

In the reply, he says "Paypay."  I am not familiar with that, but may be 
"PayPal" and simply a typo.

Personally, I am disappointed in that it cannot be adapted to the popular 
Larry Cochrane AD-Amp electronics.  However, I still feel it necessary to 
pass on this to the PSN Group.

Best Regards,
Jerry

Gerald,

Thanks for your email. In answer to your questions:

We will be implementing a Paypay facility in the next few weeks and will 
advise you when it is live. This should make payment much easier for you!

The HS-3 electronics are integral to the unit, i.e. inside the basebar and 
specifically designed by us for our capacitance sensor. Both the detector 
and microprocessor are TOTALLY digital, as is the feedback system that 
provides the additional ground tilt/earth tide signal. Hence, there are no 
analog signals involved whatsoever, and it is simply not possible to 
interface the sensor with third party electronics, nor provide an analog 
output. The HS-3 transmits digital velocity and digital ground tilt (24bit 
and 16 bit respectively) via RS232. One of the key reasons in deciding upon 
an intrinsically digital process was to eliminate the signal drift that is a 
feature of many analog systems.

We chose AmaSeis as the data logging program since this appears to be the 
most widely used package in the US and elsewhere, for example with hundreds 
installed in north American schools. However, we are aware that many people 
like to develop their own processing and plotting applications, and with 
this in mind the command protocol for the instrument is fully published, 
with software examples, so that you can craft your own code if you want. 
This could be in Visual Basic, Liberty Basic, Python, C or BBC Basic, as per 
the examples on the user CD.

  Gentlemen:

  1)    Were you ever able acquire credit card availability?

  2)    In a discussion here in the US, it was pointed out that while your 
HS-3 was VERY interesting, many of the amateur seismology enthusiasts here 
have electronics bought from Larry Cochran or their own.  They also use 
different software packages too.  These factors prohibit serious thought 
about buying the HS-3.

  Is there now or possibly could be a separate analog output for use by 
these systems?

  Thank you,
  Gerald Payton
