• IF the SI-BAM21-LCB transducer ampliﬁ er module and the 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 Input port on the front panel of the SI-AOSUB module.

• If a SI-AOSUB is being used because the system has a motor, 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-AOSUB, see "Using the Anti-Oscillation Unit" on page

27.

5. (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 29.

6. (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 35.

7. (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:
