Using A Joystick Console
The MJC001 joystick console has been designed for microscope users, to provide
intuitive, tactile, manual positioning of the stage. The console features a two axis
joystick for XY control. Up to 3 joysticks can be connected to each other, interfacing
neatly into a multi-channel control application. Furthermore, if the parameter settings
are persisted to the controller (see Section 5.3.) the controller need not be connected
to a host PC, thereby allowing remote operation.
1) Connect the stage to the Controller unit.
2) Connect the joystick console to the HANDSET IN connector of the controller.
3) Switch ON the controller.
4) Wait until the red led on the joystick console and the Channel Enable LEDs on the
controller front panel stop flashing (~3s). This indicates that phase initialisation is
complete.
5) Press and hold the ‘High/Low’ button for 2 seconds to home the stage. When
homing is complete, the green LED stops flashing.
In order to establish control over a particular axis, the joystick axes must be associated
with the corresponding channels of the related controller. This is achieved by setting the
joystick ID switch, located on the underside of the joystick console, and the channel ident
switches on the rear panel of the BBD controller.
The joystick ID switch assigns the selected number to the X axis of the joystick and the
next sequential number to the Y axis. The channel ident switches on the controller unit
must then be set to match these joystick axis numbers.
For example, if the joystick switch is set to '1', then the X axis channel ID switch on the
controller must be set to ‘1’ and the Y axis ID switch must be set to ‘2’ as shown in Fig. 4.1.

Note
The default parameter values loaded at the factory should be acceptable for
most applications, and in this case, it is not necessary to connect the
controller to a PC running the APT software. If these parameter values
subsequently require adjustment, this can only be perfromed by running the
APT software - see Section 3.1. and Section 5.3. for more information.
