5.2.2 Structure and Operation of the Configuration Matrix
General This section deals with the structure and operation of the configuration matrix. The
configuration matrix can be viewed without making any configuration changes. Infor-
mation characteristics and configuration steps are described in Sub-section 5.2.4, and
configuration is demonstrated in Sub-section 5.2.5.
Configuration of information is performed, using a PC and the DIGSI
®
4 software pro-
gram, via the operator or service interface. The configuration is represented in
DIGSI
®
4 as a matrix (Figure 5-4). Each row is assigned to an information of the de-
vice. It is identified by a function number No, LCD text (display text D), an explanation
(long text L, minimized in Figure 5-4), and an information type T. The columns give the
interfaces which should be the sources and/or destinations of the information. In ad-
dition to physical device inputs and outputs, there may be internal interfaces for user
definable logic (CFC), message buffers, or the device display.
