1.1 Using the Dlink+ w/CPDLC
The Dlink+ w/CPDLC emulates a 14-line ARINC 739 Multi-purpose Control and Display Unit (MCDU )
using a 9 line display to show the information in two parts called the A and B screens.
•The A screen puts the MCDU title line on line 1, MCDU lines 2 through 7 on display lines 2
through 7, and the MCDU scratch line (line 14) on line 8.
•The B screen puts the MCDU title line on line 1, MCDU lines 8 through 13 on display lines 2
through 7, and the MCDU scratch line (line 14) on line 8.
•When there is any text from MCDU line 8 through 13 on the B screen, the text above the lower
left Line Select Key (LSK) will read “A/B” and the rightmost character of display line 1 will show
the current screen (either A or B). Pressing the lower left LSK (“A/B”) will toggle between the two
screens.

Dlink+CPDLC Users Guide
1.1.1 Basic User Interface
When first powered up or restarted, the Dlink+ w/CPDLC will appear as follows:
Note: The 1
st
line may have the airline name and unit version number.
1.1.2 Keyboard
Entering text from the keyboard will be shown on the “scratch pad” line located near the bottom of the
display. Entered text will start at column 1 and be added left to right. See Figure 1.1.1-1 Dlink+
w/CPDLC Text Line Identificaiton.
1.1.2.1 Alpha Numeric Keys
A standard QWERTY keyboard performs the expected functions. All alphabetic characters are always
upper case so they do not respond to the shift key.
1.1.2.2 Non Alpha Numeric Keys
1.1.2.2.1 User Function Keys
The user function keys are located at the top of the keyboard. Functionality is provided for each of
the keys. Function of each key is dependent on the state of the shift key.
Document Number: UG-14114 Rev. - Page 9 of 201
Dlink+CPDLC Users Guide
Functions associated with each non-shifted User Function Key:
• ACARS – Displays the ACARS Index Menu.
• MSG– Displays the ACARS messages log.
• READ– Displays the Monitor menu page.
• SEND– Displays the Aircrew Miscellaneous Message page.
• EMRG – Displays th e E7500 Menu.
• USER– Displays the Main System User Menu.
• MENU – Displays the Subsystem Menu.
• CPDLC – Displays the CPDLC Index Menu.
The following functions associated with each shifted User Function Key:
• ACARS – Displays the ACARS Index Menu.
• MSG– Displays the ACARS messages log.
• READ– Displays the Station Table Menu.
• SEND– Displays the ATS Free Text Menu.
• EMRG – Displays the E7500 Menu
• USER– Print the current ACARS message if displayed else print current menu.
• MENU – Displays the Subsystem Menu.
• CPDLC – Displays the CPDLC Index Menu.
Pressing the MENU user key selects the MCDU MAIN MENU where any additional devices using
the Dlink+ w/CPDLC as an MCDU can be selected. Normally this only displays” <DLINK+” for the
Dlink+ w/CPDLC internal display functionality.
1.1.2.2.2 Line Select Keys
There are 9 Line Select Keys (LSKs): 3 on the left and right sides of the display and 3 below the
display.
The function of the 3 lower LSKs are:
1) LEFT is the A/B select. This LSK will toggle between A and B screens. If there is no text
on the B screen the LSK is ignored and the text above the key is blank. If this LSK is held
for 2 seconds a “lamp test” is performed. The annunciator lamps will illuminate briefly then
go out and all of the pixels on the display will turn on while the key is held.
2) CENTER is below the Advisory field. Its function changes depending of the content of the
advisory field.
3) RIGHT is the NEXT/PREV page key. When the shift light is off this is NEXT and when the
shift light is on this is the PREV key. When a menu contains multiple pages, the right end
of line 1 (next to the A/B character) displays “n/m” where “n” is the current page and “m” is
the total number of pages. Pressing NEXT increments the current page and pressing PREV
decrements it. If the menu contains only 1 page pressing this LSK will cause the data on
the display to be refreshed.
The three left and right LSKs map to the 6 MCDU left and right LSKs. When the A screen is
displayed they map to MCDU LSKs 1 through 3 and when the B screen is displayed they map to
MCDU LSKs 4 through 6. The character on the display closest to the LSK determines the
function the LSK will perform.
1) “<” or “>” indicates another menu will be displayed.
2) “*” indicates a function will be called or a message will be sent.
3) “[“ and “]” indicates a selection field and each press of the LSK will select the next item in
the selection list.
Document Number: UG-14114 Rev. - Page 10 of 201
Dlink+CPDLC Users Guide
4) Any other characters normally indicate a variable field for data entry. Pressing the LSK
while the scratch line is blank will cause the current contents of the LSK variable to be
copied to the scratch line for editing. Pressing the LSK when there is data on the scratch
line causes the contents of the scratch line to be copied to the LSK field. The data is
verified before it is inserted and an error message is display for any problems.
5) Text can also be displayed on a line next to an LSK and the LSK will have no defined
function. In this case, pressing the LSK will result in a warning on the scratch line.
1.1.2.2.3 Arrow Keys
The function of the up (^), down (v), left (<), and right (>) arrow keys changes depending on the
circumstances:
1) Normal operation
• UP and DOWN move through multiple page menus ½ a screen at a time.
• LEFT is the equivalent of the Return key
• RIGHT is ignored.
2) Edit mode
• UP and DOWN have the same function as normal operation.
• LEFT and RIGHT move the cursor (an underscore) on the scratch line.
1.1.2.2.4 Clear Key
1) If a message is displayed on the scratch line it clears the message and restores the text
that was on the line.
2) If in edit mode it performs a backspace delete function.
3) If held for more than 1 second it clears the scratch line.
1.1.2.2.5 Enter Key
1) When data has been copied to the scratch line by pressing the associated LSK, pressing
ENTER stores the edited data to the original LSK field.
2) When entering a password the ENTER key enters and checks the password.
1.1.2.2.6 Del Key
The DEL key deletes the character under the cursor.
: (Shift is off, no data on the scratch line)
: (Shift is off, there is data on the scratch line)
1.1.2.2.7 Return Key
The Return key returns to the previous menu if there is one. If there is no previous menu it is
ignored.
1.1.2.2.8 +/- Key
This key displays a minus in the scratch pad on the first press and will toggle to + with a second
press. It does not change based on the shift key.
1.1.2.2.9 Shift Key
The shift key operates as a shift lock key. Pressing it toggles the shifted/not shifted lamp (lamp is
on when shifted). Do not hold down the shift key to produce a symbol from the numeric keys.
Simply press shift once to turn on the lamp then press the numeric key to get the desired symbol.
Press shift again to turn it off.
1.1.3 Advisories
The Advisories alert the pilot to messages or problems.
