Required Installation. This section provides basic setup information for the aircraft type currently selected. It
includes the UTD installation angle and the type of accelerometer selected for each of the channels.
The Setup Menu contains all the operations to change the current system's setups, see figure 5. The following is
a description of those operations:
The AVA contains a print spooler that is capable of storing up to twenty selected screen images and sending
them to the printer. The CADU provides both parallel and serial interfaces for printers. The serial interface is
used with the AVA printer or a serial printer with Epson graphics. The parallel interface is used with printers
containing a Centronix parallel interface with Epson graphics. In order to change the number of screen
images that can be stored, refer to ENABLE command. The CADU is designed to control several different
serial interface type printers, such as Epson compatible printers and the AVA printer. Place the cursor over
the Printer selection and press DO. Use the UP and DOWN arrow keys to maneuver through the menu
selections described in the following paragraphs.
(a) Changing Printer Types
To change the printer type, position the cursor over the Change Type selection in the Printer Control
Menu, figure 6, and press DO. A list of available printer types will be displayed. Position the cursor over
the desired type and press DO. The new printer type will be installed.
(b) Changing Printer Ports
To change the printer port type, position the cursor over the Change Ports selection in the Printer Control
Menu and press DO. A Printer Ports selection menu allows the operator to select either the parallel or
serial printer port, which ever is required for the printer being used.
(c) Enabling/Disabling Print Spooler
The print spooler buffers screen images for printing while the printer is not hooked up. Once the printer is
hooked up, the screens will be printed out in the order that the screens were spooled to the buffer. When
the spooler is enabled, screens are printed. When the spooler is disabled, screens are just buffered in
the CADUs internal memory. After the CADU is rebooted, the print spooler is returned to the enabled
state. To enable or disable the print spooler, position the cursor over the desired selection in the Printer
Control menu and press DO. It is recommended to leave print spooling enabled.
(d) Flushing Print Spooler Buffer
Screens that have been previously spooled can be deleted, if printing is no longer desired or a user
prefers to print new screens rather than old screens. To delete old buffered screens, position the cursor
over the Flush Queue selection and press DO.
(e) Printer Spooler Failure
In the event of a printer spooler failure, it will be necessary to restart the spooler. To restart the spooler,
position the cursor over the Restart Spooler option and press the DO key. This option is only available if
the printer spooler is not running.
Setting System Time and Date Function
This function allows the current time and date to be changed. To select this function, place the cursor over
the Set Time & Date option and press the DO key. An entry will appear. Use the UP and DOWN arrow keys
to move through the selections. Use the HELP key on a chosen selection (highlighted) for specific
information on that choice. Use the numeric keypad to enter values. In cases where two digit values are
required (such as the date) use the LEFT and RIGHT arrows keys to position over the appropriate digit to be
changed. To cancel changes, press the QUIT key to exit anytime.
