{{A}}
==Application==
The Dual Display station is primary intended to be used as a table top station in bank / finance environment and offices where quick access to several preprogrammed extension numbers and functions is essential.

The direct access key display text can be edited

==The principal==
DAK-labelling is stored in the station memory
:* Labels are sent from the exchange as display data

The station recognises 10 DAK-pages

DAK-page 3 reserved for the 4 function keys
:* DAK-buttons 21-24, buttons 25-30 are unused

The dialling code sent on the abcd-wires (for analogue stations) depends on the selected DAK-page

==DAK-keys in the AMC==
Each station has a DAK-table with 24 lines (from AMC9)
:* 20 lines are for general use (1-20)
:* 4 lines are reserved for navigation keys
More DAK keys can be reached via re-direction

==DAK-redirection==
Only DAK 1-10 can be used for redirection of DAK keys to other stations. DAK 11-20 cannot be used for redirection.

::*DAK 22: Arrow Up
::*DAK 23: Arrow Down
::*DAK 24: Context sensitive Cancel/Esc
::*Not user programmable
::*The navigation key labelling can be altered in the MDF-file

:*DAK label = “Door A4”
:*Max DAK-string length: 19 char.
:*Max label length: 8 characters
:*Must be the last command in the string
[[Image:DualDisplayConfig3.png|left|400px]]
[[Image:DualDisplayConfig6.png|left|400px]]
<br style="clear:both;" />

----

DAK-string without T-command: I 102
:*DAK label = the first 8 characters of the display text of 102
:*Only available when programmed as directory number from Idle (“I”)
[[Image:DualDisplayConfig2.png|left|400px]]
[[Image:DualDisplayConfig5.png|left|400px]]
<br style="clear:both;" />

----

Station flag ‘DAK display show directory number’ is set: 
:*DAK label = directory number instead of display text
:*Only available when programmed as directory number from Idle (“I”)
[[Image:DualDisplayConfig4.png|left|400px]]
[[Image:DualDisplayConfig7.png|left|400px]]
<br style="clear:both;" />

==DAK programming – Station(1)==
Assign directory number to DAK-key
:*Press ‘Name’, + arrow-down to select ‘ProgramKey’, followed by OK
:*Enter the directory number 
:*Press the DAK-key
[[Image:Bilde11.jpg|left|500px|thumb]]
<br style="clear:both;" />

Delete the DAK-key programming
:*Press ‘Name’, + arrow-down to select ‘ProgramKey’, followed by OK
:*Press the DAK-key to be deleted
:*Confirm by pressing ‘Del’ 
The 784 + number + DAK is also possible to use
[[Image:Bilde12.jpg|left|500px|thumb]]
<br style="clear:both;" />

==DAK programming – Station(2)==
Program a DAK label from the station
:*Press ‘Name’, + arrow-up to select ‘EditDAKText’, followed by OK
:*Press the DAK-key
:*Use the station keyboard to enter the text, maximum 8 characters
:*Backspace and space can be entered via the arrow keys
:*Confirm with OK

==DAK page limits==
*The station is designed for 10 DAK-pages
*DAK-page 3 is fixed for navigation key use
*DAK keys 1-24 (the first 2 pages and the navigation keys) can also be used during conversation
*DAK keys 31-50 are OK from idle. Features during conversation (e.g. door opening) sometimes fails
*DAK keys 51-100 are OK from idle. Features during conversation (e.g. door opening) always fails

 '''IMPORTANT!:''' Due to the above, the station is marketed as a station with 2 DAK-pages + navigation keys

==DualDisplay station used for Call Queuing==
With its 4-line display the DualDisplay is suitable to use as a "Guard station" to receive [[Call Request]]s from substations. The navigation keys can be configured to scroll and answer the call queue.

===Configuration for Call Queuing===
When the DualDisplay station is used for call queuing the following settings should be made in [[AlphaPro]]:
* In Users & Stations, set '''Station Type''' = "CRM"
* In Users & Stations, select the tab 'Station Type' and set the flag '''Station use DAK-display'''
* In Users & Stations, press ['''DAK'''] and select the tab 'Navig. Keys'. Enter the [[Mail_Queue_Operation|queue navigation codes]] for answer, scroll and delete:
::- Navigation key 1: 7638 (Answer)
::- Navigation key 2: 7637 (Up)
::- Navigation key 3: 7639 (Down)
::- Navigation key 4: 7630 (Delete)

Note that when the Station Type is set to "CRM" there will be no notification tone upon arrival of new Call Requests (this is by design because the notification is done by separate buzzer in the [[Control Room Master IV|CRM IV station]]). Because [[Send Call Request Feature|Normal Call Request (623)]] is indicated by a bleep every minute ([[Feature reminder]]), it might be more suitable to use [[Send Call Request Feature|Alarm Call Request 622]] which is indicated by the programmable [[Urgent feature reminder]].

===Controlling the video-state of the DAK-display===
The [[Event Handler]] command [[IND]] can be used to control the video-state of the DAK-display of the DualDisplay station. The video-state of each DAK key label can be controlled. The options are normal video (default), inverse video, slow flash normal/inverse video and fast flash normal/inverse video.

Format of the IND command:
*IND x y 1 z
:*x = physical station (1 - 552)
:*y = DAK-line (1-100)
:*z = video-state
::*z = 0: Normal
::*z = 1: Inverse
::*z = 2: Slow flash
::*z = 3: Fast flash


Configuration example:<br>
When receiving a Call Request, the DAK key label of the calling substation should flash fast.<br>
Create an event with the following parameters:
{| 
|-
|width="100pt"|'''Event Owner''':
|width="300pt"|The DualDisplay station
|-
|'''Event type''': || [[Received Mail (Event Type)|10 – Received mail]]
|-
|'''Subevent''': || 0
|-
|'''When change to''': || ON or OFF
|-
|'''When related to''': || All
|-
|'''Action''': || IND %1.phy %1.dak(I%2.dir) 1 3
|-
|}
<br>

===Move to DAK page when receiving Call Request===
====Analog Dual Display station====
Use Event Handler and $DSPL Command to select DAK page

 $DSPL L104 U3 500400 <nowiki>''</nowiki>

This will select DAK page 4 on station 104 
*U3 = 3 bytes (50 04 00)
:-50 = ‘page select’-command 
:-04 = page number (01, 02, 04, 05, 06, 07, 08, 09, 0A)
:-00 = Define the Arrow Up/Down in the DAK display
::*00 = No Arrows in DAK display
::*When this number is higher than the selected page number, an up- and down-arrow will be displayed if page number > 1
::*Examples:
:::- 500405 = Page 4 with Arrow Up and Down
:::- 500404 = Page 4 with Arrow Down
:::- 500403 = Page 4 with Arrow Down
:::- 500104 = Page 1 with Arrow Up
:::- 500400 = Page 4 with no Arrows

'''Use as CRM - Example:'''
[[Image:DD Event1.PNG|left|500px|thumb]]
<br style="clear:both;" />

When DualDisplay receive a call request
:*display shows correct DAK page
:*DAK text is fast flashing
 $DSPL L%1.dir U3 50 %op(%op(%op(%1.dak(I%2.dir),-,1),/,10),+,1) 00 <nowiki>''</nowiki>
 IND %1.phy %1.dak(I%2.dir) 1 3

====IP Dual Display station====
Use Event Handler and $DIP Command to select DAK page:

 $DIP L101 "dakpage 5 6"
 $DIP L%1.dir "dakpage %op(%op(%op(%1.dak(I%2.dir),-,1),/,10),+,1) 10"


This command means: show DAK page 5 of 6 on station 101.

* 5 = page no: DAK page number to activate 1 - 10. 
* 6 = max page: Maximum number of pages configured for the station (Arrow configuration). 0 means no arrows will be displayed.

==Write to the display==
===Analog Dual Display Station===
Use $DSPL command:

 $DSPL  L104 U11 33011302  'Hello'
*Displays ’Hello’ on DAK display line 2
**U11: Length of data to be sent (11 bytes)
**33: write to multi display system (Constant)
**01: Display 01 (Constant)
**13: write text (Constant)
**02: DAK-line 02 (range 01-64 in hex, which is 1-100 decimal)

NOTE: text written this way maybe overwritten by an exchange display update

===IP Dual Display Station===
{{note|This function is currently not supported fully. You can write to the display, but then all the other lines will be cleared}}
 $DIP L104 'dakte 2 "Hello"'
*Displays ’Hello’ on DAK display line 2
:-2 DAK-line 02 (range 01-64 in hex, which is 1-100 decimal)

Note that line number is in hex, line 10 is "dakte A".
