1. With the STOP/SET button is held down, a momentary press of WORK POS. makes the current
location the “Work Position”. A beeper will sound to indicate that the operation is complete and
the location has been saved. Typically, this is a location where the pipette tip is under the
microscope objective and near the cells or tissue of interest.
2. Once you have defined a Work Position, a momentary press of WORK POS. will cause the
manipulator to move to the defined Work Position, providing the manipulator’s last move was to
Home. The move will occur along the predefined path that the manipulator moved to get to Home
(described above) but in the opposite direction. This is the reason why Work Position moves must
follow Home moves; the move to Home defines the return trip. In either case, the movement along
the diagonal as you come in and out of the preparation/dish/bath should assure that the pipette tip
will not hit anything on the way in or out.
3. When WORK POS. is held down for longer than 2 seconds, the current manipulator is locked so
that none of the buttons or the ROE knobs will cause it to move. The lock is released by holding
WORK POS. down again. A beep will indicate that the lock is enabled or disabled and the display
will indicate the locked state.
STOP/SET: This button has two functions:
1. When held down, STOP/SET” performs a “Set” function in combination with the “WORK POS.”
key. Think of it as a shift key when held down.
2. A momentary press of STOP/SET during a robotic move (see HOME, WORK POS. and CENTER)
will immediately “Stop” the movement. Think of this as your panic button when you see your
pipette headed somewhere that you don’t want it to go!
Black Selector Switches:
MODE: The MODE Selector controls the speed and the relative fineness of movement of the
manipulator produced by rotating the ROE knobs. As MODE increases from 0 to 9, movement gets
finer and slower. As explained in “INITIAL OPERATING INSTRUCTIONS”, MODE 0 is Accelerated
Mode. In MODE 0, slow turns of the ROE knob produce medium course moves for moving a pipette
under a microscope in the vicinity of a cell. Prolonged, fast turns of the ROE knobs cause the
controller to accelerate to top speed for long, imprecise movements for rapid manual positioning of the
pipette. The remaining MODES (1-9) produce moves of increasing sensitivity and decreasing speed.
In practice, most users will find that MODE 5 or 6 will provide the necessary dexterity of movement
for the final approach to a cell. The current MODE setting is displayed in the upper right of the ROE-
200 display.
MANIPULATOR: The MANIPULATOR Selector toggles the active manipulator. Both an LED and
the named manipulator on the ROE display change to signify which manipulator is active. When the
MANIPULATOR A output is selected, LED 1 will light and the display will say “DriveA” in the upper
right hand corner. When the MANIPULATOR B output is selected, LED 2 will light and the display
will say “DriveB”.
The status of a particular manipulator is preserved when you toggle to the other manipulator. Status
includes the current position, current MODE (speed) setting, whether or not you are in diagonal or
orthogonal movement, and whether the manipulator is currently locked. Also, a separate WORK POS
is maintained for each manipulator in use.
A separate set of DIP switches is present on the back of the controller for controlling setup of the two
different manipulator outputs. See “Controls on the MPC-200, page 12.
You can also configure how the MANIPULATOR Selector operates. The selector can function as a two
position toggle, where pressing the left side of the toggle selects Manipulator 1 and pressing the right
side of the toggle selects Manipulator 2, or the selector can function in a cyclical fashion, pressing once
on either side selects the other manipulator and pressing twice reselects the manipulator you are
already on. Selection method is determined by DIP switch 3 on the back of the ROE.
