Quad pH/mV Amp
First make sure that the
e-corder
is turned off. Then connect the I
2
C
cable to the I
2
C connector on the back panel of the
e-corder
, and the
other end to the I
2
C Input connector on the back panel of the pH/mV
Amp. Use BNC cables to connect the signal outputs on the back panel
of the Quad Tc/mV Amp to the front panel of the
e-corder
as shown in
Figure 2–4
and
Figure 2–5
.
Check that all connections are firm. Loose connections may cause
failure to recognize the eDAQ Amp by the software, erratic behavior,
or loss of signal.
Multiple eDAQ Amps can be connected to an
e-corder
. The number
that can be connected depends on the number of input channels on the
e-corder
. The initial eDAQ Amp should be connected as shown in
Figure 2–5
. The remainder are linked via I
2
C cables, connecting the
I
2
C output of one eDAQ Amp to the I
2
C input of the next. The signal
outputs of each eDAQ Amp are connected to an input channel of the
e-corder
.
