6.3 File formats
6.3.1 PPT image
Filenames: PPT50Image.img.gz, PPT50Image.md5, PPT50Image.img.gz.sig
The PPT image is a compressed image of the PPT system (Power Panel T-Series operating system). File PPT50Image.img.gz contains the image and file PPT50Image.md5 contains the MD5 checksum of the image.
During an update, the MD5 checksum determines if the PPT image is free of errors.
This Power Panel supports signed images. During an update, the Power Panel checks the provided signature PPT50Image.img.gz.sig to determine if the image package comes from a trusted source.
6.3.2 System settings
Filename: PPT50Config.xml
The system settings, which can be defined by the user on the service pages, are saved on the Power Panel in XML file PPT50Config.xml.
When you back up and restore (see the two service pages Backup & Reset and Update) the system settings, the data is exchanged using an XML file with the following name.
6.3.3 Boot logo
Filename: PPTLogo.bmp.gz
The boot logo is displayed during the boot phase of the Power Panel.
If configured on service page Startup, the boot logo is also displayed while establishing a connection in web/VNC mode.
The boot logo must meet the following requirements:
File format |
Only the BMP (Windows bitmap) file format is allowed for the boot logo. |
Size |
The size of the bitmap must correspond to the size of the display in full screen mode. |
|
To determine the size of the display on the Power Panel being used, see section "Technical data". |
Name |
PPTLogo.bmp.gz |
|
The bitmap must be compressed in GZ format (GNU zip). |
|
If the boot logo (any name possible) is added in Automation Studio and then the data for the USB |
|
flash drive is generated, then Automation Studio will compress the boot logo into the GZ format and |
|
name the file accordingly. |
|
The user only has to make sure that the boot logo is compressed into the GZ format and the file is |
|
named accordingly if Automation Studio is not being used. |
Color depth |
The color depth is limited to 24-bit. |
Application |
The boot animation is superimposed over an existing static boot logo. |
6.3.4 Boot animation
Filename: PPTLogoA.gif
If Startup is configured on the service page, the boot animation is also displayed while establishing a connection in Web or VNC mode.
The boot animation must meet the following requirements:
File format |
Only the GIF (Graphics Interchange Format) file format is allowed for the boot animation. |
Size |
The size of the boot animation must be equal to or smaller than the size of the display being used |
|
in full screen. |
Name |
PPTLogoA.gif |
|
If the boot animation (any name possible) is added in Automation Studio and then the data for the |
|
USB flash drive is generated, then Automation Studio will name the file accordingly. |
|
The user only has to make sure that the boot animation is named accordingly if Automation Studio |
|
is not being used. It is important to ensure that capitalization matches the name specified above! |
Position |
When specifying the position of the boot animation (see service page Screen), it is important to ensure |
|
that the entire boot animation is shown on the display. |
Application |
The boot animation is superimposed over an existing static boot logo. |
|
The boot animation is only displayed when starting Web or VNC mode. It is not displayed while the |
|
device is booting. |
