You can have texts and variables of up to 16 characters displayed on the SC Master or SD Event Control display. For this purpose you need to configure a serial port as a display in the Media Pool.
In the Media Pool, click category 
Devices, right-click the device folder, e.g. SC Master and select Add devices. Select Serial and click on OK to add a serial port.
In the Media Pool, double-click the new port to open the corresponding Properties Dialog. Enter Display as a name as well as the display address:
1/2 ...for SC Net Port and a Master unit with device address 1
C1 ...for a DLC-Port
Close the dialog by clicking OK.
Drag the new device Display into the timeline and a marker track containing a command marker will be created. Double-click the marker and enter the text and the display duration under Command/Text, e.g.
"Text" 240
The text to be displayed (with a maximum of 16 characters) is in quotation marks followed by a space and 240 (hexadecimal value for 240) for a display duration of 2.4 seconds. With an entry of 255 the text is displayed continuously until the next message arrives.
Click on OK. You can check text output by playing the command marker with the device control system being enabled.
For displaying variables you take the same steps as for the text display. But you also need to specify the variable to be displayed, which is preceded by a percent sign:
"Text %X" 240
Text and variable are in quotation marks, % signalises that variable X (entered in ASCII code; see table) is to be displayed, followed by the display duration, e.g. 240 for 2.4 seconds.
Example:
"Service in %4 Tg" 255
This command reads out memory variable E4 and would be displayed as follows, if the variable had a value of 26, for example:
Service
in 26 days
This message continues to be displayed because 255 was entered as display duration.
This way the values of previously set variables can be displayed. See Setting variables. The list below will tell you the variables to be displayed, as well as the corresponding ASCII and hex code values.
Variable ASCII 
Hex
Memory variable E1 1 15
Memory variable E2 2 16
Memory variable E3 3 17
Memory variable E4 4 18
Memory variable E5 5 19
Memory variable E6 6 1A
Memory variable E7 7 1B
Memory variable E8 8 1C
Memory variable E9 9 1D
Memory variable E10 10 1E
Memory variable E11 11 1F
Memory variable E12 12 20
Variables E13 to E30 cannot be displayed.
Runtime variable R1 31 01
Runtime variable R2 32 02
Runtime variable R3 33 03
Runtime variable R4 34 04
Runtime variable R5 35 05
Runtime variable R6 36 06
Runtime variable R7 37 07
Runtime variable R8 38 08
Runtime variable R9 39 09
Runtime variable R10 40 0A
Runtime variable R11 41 0B
Runtime variable R12 42 0C
Runtime variable R13 43 0D
Runtime variable R14 44 0E
Runtime variable R15 45 0F
Runtime variable R16 46 10

Runtime variable R18 48 12
Runtime variable R19 49 13
Runtime variable R20 50 14
Runtime variables R21 to R70 cannot be displayed.
Please remember that memory variables (E1 to E30) need to be initialised by setting them a first time. They can only be displayed on the SC Master display after that.
