Configuration / Firmware Update
When the device is switched on, the directory SYSTEM is created on a connected
USB storage medium. This directory is used exclusively for system maintenance and
configuration and can contain the following files:
5.1 Release Notes
The file
INFO.TXT
contains information about the installed software.
5.2 Configuration via CONFIG.INI
The factory interface settings can be changed by the user. For this purpose, a text
file CONFIG.INI must be created with the desired settings. Comment lines start with
the # character. Numbers are interpreted decimally or hexadecimally (by prefixing
them with 0x). In case of missing or invalid entries, the respective factory default val
-
ues (see Table 10 on page 17) are taken for setting.
The following settings are possible:
