programmable fi lter module (or
SI-AOSUB
anti-oscillation module) are not
connected to each other through the backplane of the Signal Conditioning
Amplifi er System, these two modules must be connected through ports on the
front panels of the modules. Use a BNC-BNC cable to connect the
Force Output
port on the front panel of the
SI-BAM21-LCB
module to the
Signal In
(LPF IN)
port on the front panel of the
SI-PF100
module (or to the
Input
port on the front
panel of the
SI-AOSUB
module).
• If
an
SI-PF100
is used because the system has a motor, it can fi lter the low
frequencies from the input signal. Use a BNC cable to connect the
Signal Out
port (LPF OUT) on the front panel of the
SI-PF100
module to the analog input of
the data acquisition system, which is designated as the force recording channel.
• If
an
SI-AOSUB
is being used instead of a
SI-PF100,
then use a BNC cable to
connect the
Corrected Output
port of the
SI-AOSUB
module to the analog
input of the data acquisition system, which is designated as the force recording
channel. The
Corrected Output
is the signal from the transducer amplifi er that
exists after the resonance frequency of the transducer was removed from the
raw transducer signal by the anti-oscillation fi lter.
For information on using the
SI-PF100
, see "Using the Programmable Filter" on page
28 or on using the
SI-AOSUB
, see "Using the Anti-Oscillation Unit" on page 29.
4. (Optional) If a Sarcomere Length Unit Is included, connect the
SI-SARCAM
as follows:
•
Connect the cord from the laser to the
Laser
connection port.
•
Connect the cord from the camera to the
CCD
connection port.
•
(Optional) Connect the
Video
BNC port to an oscilloscope to display the laser
diffraction pattern.
•
To monitor the approximate sarcomere length over time, connect the
Sarcomere
BNC connector to an analog input on your data acquisition system.
•
To track the distance from the center laser beam to the fi rst order of diffraction,
connect the
Distance
BNC connector to an analog input on your data acquisition
system.
For information on using the
SI-SARCAM
, see "Using the Sarcomere Length Unit" on
page 31.
5. (Optional) If cuvette temperature control is required, connect the
SI-TCM2B
as fol-
lows:
•
Line up the cuvette connector on the heating cable of the cuvette with the CH1
or CH2 port on the
SI-TCM2B
, press it into place and screw the outer ring of the
connector to secure the connector. A second cuvette may be connected to the
other port, if necessary.
•
To monitor the temperature over time, use a USB cable to connect a computer's
terminal emulation program using the USB port on the
SI-TCM2B.
For information on using the
SI-TCM2B
, see "Using the Temperature Control Module"
on page 36.
6. (Optional) If a Constant Load Module is installed, the connections that are made
depend upon the mode of operation. Three modes are available (Constant Load,
External Loop and Bypass). Make the connections according to the following table:
