4.3 Using the Z Axis Digipot (CS152Z)
This device is normally used for OptiScan II systems where
motorised focus is required but a motorised stage is not. It
provides control of the focus motor only.
The digipot control drives the focus motor directly.
Rotating the control knob in opposite directions
will drive the focus motor in opposite directions.
The speed control button can be used to change the
maximum speed of the focus motor when controlled from the
digipot. Press once to reduce the speed to 50% of maximum, a second time for 25% of
maximum and a third time to return to 100% of maximum. This cycle can be repeated by
continuing to press the button.
Two other buttons are provided which allow the focus motor to be driven ‘Up’ or ‘Down’ by
pressing and holding the appropriate button. This feature allows for rapid positioning over
larger distances.
4.4 Using the Filter Wheel Keypad (CS100K)
The Filter Wheel Keypad (CS100K) provides control of up to 2 filter wheels and 3 shutters at
the press of a button.
It communicates to the OptiScan II controller via the
RS232-2 port located on the rear panel (see fig.4.3).
Ensure that the controller is switched off
before connecting the keypad.
Switching on the controller automatically
initiates a ` homing' routine and either the FW1 or
FW2 green LED will be illuminated. Filter wheel position 1 on
the keypad will be activated, indicated by a red LED.
Three buttons are provided to control up to 3 shutters.
Fourteen buttons are provided to control up to 2 filter wheels.
The button labelled ‘P’ is for future developments and currently has no function.
