4.3 Using the RS-232 interface port
Most products in the iCOMPEL range have a single RS-232 port presented on a 9 way D type plug.
Sending user defined RS-232 strings at specific events or at Playlist positions. The strings must be defined as their byte
values expressed as separated hexadecimal nibble pairs. E.g. 3a 3b 3c 0d 0a. It is up to the user/installer to create the
strings in accordance with the needs of the attached device/s. Sending of RS-232 commands is unaffected by the state of
any of the RS-232 control lines.
Receiving RS-232 strings
The most recently received string is reported by the iCOMPEL in the Items Tab of the RS-232 Outputs page. At software
version 6.2 (and lower), the iCOMPEL provides no interpretation of the strings. Receiving RS-232 commands is unaffected
by the state of any of the RS-232 control lines - see below.
4.4 Displaying part of a Movie or Web page
It is possible to display only part of a web page or part of a movie. You can use this feature to show a specific area of a web
page without resizing it.
You can also use this feature to crop a movie designed for a 16x9 (widescreen) format to a 4x3 (standard) format. This
avoids resizing the Zone, which would alter the aspect ratio and distort the image.
Displaying part of a Movie
To display only part of a Movie, follow these steps:
From the menu bar, select Setup, then UI Options.
For the User Interface Options, select Detailed or Expert.
Select the Layout and Zone for the Playlist including the Movie and click Edit.
Under Movie Size, select Show part of Movie, and enter the left and top edge offsets for the top left corner of the part
of the Movie that you wish to show in the Zone and enter values for Movie Width and Height.
Displaying part of a Web page
To display only part of a web page, follow these steps:
From the menu bar, select Setup, then UI Options.
For the User Interface Options, select Detailed or Expert.
Select the Layout and Zone for the Playlist including the HTML page and click Edit.
Under Web Page Size, select Show part of Web Page, and enter the left and top edge offsets for the top left corner of
the part of the web page that you wish to show in the Zone and enter values for Web Page Width and Height.
4.5 Mitigating plasma screen burn
Plasma screens can suffer from screen burn if parts of the screen always show the same image. This means that an
impression of the image can become burnt into the screen. Screen burn is less likely on LCD panels. Many plasma
screens have their own built-in burn mitigation features and these should be activated. If, however, you wish to take further
steps to mitigate the problem then you need to either change the background image or the Layout at regular intervals and/or
use the plasma burn mitigation mechanism built into the iCOMPEL.
