This screen is used to select the interface to the focuser and to open or close the connection to the focuser.
Selecting the Interface:
Select the drop down arrow 
to display the list of
available interfaces. When using USB you will select the top option.
Following are the RS-232 communication ports COM1 through COM15.
The port you select will be saved in the registry so you should
not need to select the interface each time you run the software. In
the event that you need a COM port above 15 please contact Starizona and
we should be able to accommodate your needs.
Connecting/Disconnecting:
Once you have selected your USB or COM port press the 
button to open the link to the focuser. To close the
connection to the focuser press the 
button.
Changing the Speed Delay: The Speed Delay determines how many seconds
the hand controller will move at the slow speed before it switches to
high speed. To
modify this value type the desired delay into the edit box and hit the
button. The
speed delay change should be reflected in the text below the button.
Changing
the Steps per Count: The
Steps per count determines how many steps the servo motor will move for
each count change on the hand controller display. This
allows you to increase the total travel that the focuser will move for
a given range of counts. Be
aware that increasing this value will reduce the resolution that the motor
can be driven. To
modify this value type the desired steps per count into the edit box and
hit the 
button. The
steps per count change should be reflected in the text below the button.
Changing the Motor Speed: The
Motor Speed determines whether servo motor will run at normal speed or
high speed. To
modify this setting select the desired speed in the combo box and hit
the 
button. The
motor speed change should be reflected in the text below the button.
Exiting the Application: Select
the 
button or the close button 
on the
menu bar to exit the application. If the focuser is being accessed
from a client application then closing the software will only hide the
application. The process will still remain active until all clients
have released control.

the number of packet transfers to the motor controller as a method to
provide feedback that programming is working properly.
