Configuration and diagnostic program
The system allows a very wide range of programming, that are defined in the configuration program on the PC, and with help of USB or serial interface are recorded to the C.I.E. The configuration program is used to assign the user text to individual addresses of system, parameterization of interactive detectors, creating of individual groups of detectors and defining of their properties. Also serve to define the properties and relationships in the system, such as the conditions for activation of the individual outputs, activation of user bi-color LED, a way of signaling by the activation of input, etc. It is also used for system diagnostics and firmware update of C.I.E.
