5.5.2.1 Open
The Open function is used to establish a connection to a specified synthesizer. A
synthesizer is selected with the upper right hand pull-down menu.
5.5.2.2 Close
The Close function is used to disconnect the currently selected synthesizer. A new
synthesizer may then be selected with the upper right hand pull-down menu, and the
Open function.
5.5.2.3 Refresh
Once a synthesizer has been selected with the Open command, the Refresh function
may be used to read the current status of the synthesizer. If the GUI checkbox for
Remote and Local Lockout has not been checked, the Refresh function will read the
current status of the unit as commanded via the synthesizer’s front panel.
5.5.2.4 Disable Power Checks
Within the menu this function may be selected to disable software power level
checking.
5.5.3
Synthesizer Selection Menu
This is a pull-down menu at the top right hand side of the GUI. All synthesizers which have
been detected by the software are displayed in this menu. If synthesizers are added to the
computer after the application has been started, use the ReMap Hardware function to force
the software to check for other synthesizers.
5.5.4
Remote and Local Lockout
The Remote and Local Lockout feature is enabled by a checkbox available within the GUI.
When the checkbox is selected, computer controlled operation via the USB is enabled.
Front panel control of the unit is disabled. If this checkbox is not selected, the software
application will not change any settings in the synthesizer. However in this state, if the
Refresh button is depressed, the current Frequency and Power fields will be updated with
the current settings within the synthesizer.
5.5.5
Frequency field
When the Remote and Local Lockout checkbox is selected, the Frequency of the
synthesizer may be controlled with the text-box. The desired frequency can be either typed
into the provided text-box, or either the up and down arrows on the keyboard, or the GUI
field may be used to increment or decrement the frequency by the amount indicated in the
Step box. After a new frequency has been entered, the application attempts to set the
synthesizer to the commanded frequency. If for any reason (Ex. outside the calibration
range) the unit does not go to the commanded frequency, the field will be highlighted in
yellow.
