6.0 SYSTEM MENU
6.1 Overview
The system menu allows you to examine and change settings that affect the chassis of the DFI instrument. You
can view the internal software revision and the instrument’s configuration (i.e. what types of cards are installed in
each channel).
Detailed instructions on operating the DFI instrument in the SETUP Menu mode can be found in “SETUP Menu
mode. A diagram of all menus is located in the “Setup Menu Reference” in Chapter 18.
6.2 Menu Items
6.2.1 SOFTWARE REVISION Menu Item
This displays the software part number and revision that is resident in the Microprocessor Board of the DFI
instrument.
6.2.2 CONFIGURATION Sub-Menu
When selected, a sub-menu is displayed which lists all available channels in a DFI instrument. By pressing
[ENTER] when a channel number is displayed, the card type installed in that channel is shown. If a card is not
installed in that channel, the message “NOT INSTALLED” is shown. Press [ENTER] again to return to the sub-
menu listing of all channels.
6.2.3 DIAGNOSTICS Sub-Menu
This sub-menu allows exercising and monitoring of the System connector’s output and input pins.
OUTPUT TEST Sub-Menu
Select an output pin to turn “on” (connected to pin 19) or “off” (disconnected from pin 19). The output pins are
updated immediately.
INPUT TEST Menu Item
When this item is selected, the status of all four digital inputs are continuously scanned and displayed. A “0” means
that an input is not connected to pin 19 (not asserted), and a “1” means that it is connected (asserted). Press any
button to exit this operation.
SCAN TIME Menu Item
When selected, this menu item displays the time, in seconds, that it last took for the chassis to service all of the
channels. In the RUN mode, the chassis reads each channel’s track, peak and valley value sequentially. After
each channel has been serviced, the limits are processed.
The value displayed is obtained from the last execution of the RUN mode prior to entering the SETUP menu mode.
If you enter the SETUP mode immediately after power up, the display will read “NOT AVAILABLE”.
6.2.4 INSTALL CHANNEL Menu Item
This menu item will add an Input, Output or Virtual channel as the next highest number in the system
