SCREENSAVER
The screensaver is a special page that will only be shown after a period of inactivity,
configurable by parameter.
It is possible to configure the screensaver to show the current
Time
, the current
Temperature
(selecting the desired measurement source: the internal temperature
sensor or an external value),
both
or an
image
uploaded via USB (see section 2.5.1).
The screensaver will disappear when touching the screen (also when the illumination
mode or the language changes).
Note
:
when showing the welcome greeting (see section 2.7), screensaver will not
become active.
2.5.1
SCREENSAVER IMAGE CHARGING
To upload a screensaver image just need to be copied into an USB memory device and
connect it to the USB connector of Z41. The image must fulfil the following requirements:
It has to be a JPEG image (file extension “.jpg”) with 240 x 320 pixels resolution
for vertical orientation or 320 x 240 pixels for horizontal orientation.
The image name must be “
screensaver
”, without capital letters.
The product of the width by the height of the image in pixels should not exceed
2.5 megapixels.
The image size must be less than 10MB. However, depending on the device
configuration and parameterisation, images with smaller sizes may not be set
correctly.
The USB memories must be formatted in FAT32.
If there was already a screensaver image in Z41, the image will be overwritten.
If the image resolution is greater than the screen’s, the image will be resized. To obtain
an ideal visualization it is recommended to choose an image which has the same aspect
ratio than the screen, depending on the parameterized orientation.
