Hi All,  This is really a non issue,  but since I have some time, =
waiting for project parts, I wanted to take another look at the this =
broken? DataQ board.   Looking closely at the board I see two resistors =
which are "Open" "cracked"
Its a wonder it works at all, but some parts of it do work.   Channel 1, =
only puts out + voltage, just a small amount of -
I think that account for the AmaSeis trace showing only the top part of =
an earthquake.

However Channel, 2,3,4 all seem to work showing both positive and =
negative movement "In DataQ Software Only", in this software Channel 1, =
only shows positive trace movement, and, no negative.

When I connected my Sensor to Channel 2,3 or 4 Using DataQ,  I was =
thinking it would then work in AmaSeis, but it does not.  It looks as if =
AmaSeis will not read any Channel except Channel 1.   Even though in =
DataQ Channel 2,3,4 all seem to work fine.  If I connect the sensor to =
Channel 3,  AmaSeis shows a trace, but the trace does not move in either =
direction if I stimulate the sensor.  This is true for Channel, 2,3,4.  =
Only Channel 1, moves the trace in AmaSeis.
I think you can change the com port, in AmaSeis, but is there anywhere =
you can or need to change for Channel selection?
In DataQ I closed all the Channels except Ch. 3 and saved before =
closing.  So If I were just using DataQ software, I would be =
operational.

Thanks, Ted







Hi All,  This is really a non=20
