<ImageFile> : Must match the image file name for this ESL (.bmp, .gif or .png)
<ID> : Unique product ID to which the ESL is linked
<Variant> : The 3
rd
digit of the firmware version of the ESL

user about the product in the 'ESL'-tab (useful for
sorting or searching)
<Label> : 16-digit MAC of the ESL for which the image is intended
<Width> / : Display resolution (i.e. the EE201 image size is 200 x 96 pixels)
<Height>
<Ix> : Used by the ESL server to keep track which image is currently
displayed on the ESL. It should increment from 1 to 255, 1 to
255, etc. 0=reserved for the default image. Not incrementing
the image index can lead to incorrect images on the ESL display
if a new image update for the same ESL starts before the
previous update was finished.
<Format> : Determines the image transfer protocol, for the EE201 it
should be fixed to '1'. (It’s not related to using bmp, png or gif)
To unlink an ESL, place an XML-file into the ‘Input’-folder with following name format:
