270M
Rapid Scanning Imaging Spectrograph
Wavelength Drive SENSE:
There is an internal signal that indicates the phase of the drive motor. This signal is a
nearly square wave with a period of many steps. When the calibration / high limit
switch is actuated, this signal is seen on the SENSE line. To Calibrate your controller
to
the 270M, you should step toward the high limit, until the first SENSE transition from
high
to
low. For accuracy, it is recommended that you then back off 200 steps, and
advance slowly again
to
the SENSE high
to
low transition. This exact step position
corresponds
to
the wavelength that is shown on the DMD.IN! label on the rear of your
270M.
