4. System overview

4.3.2 NetDCU The NetDCU PCB can be found on the Mainboard, connected via pin strips. The NetDCU contains an exchangeable SD memory card to store the trends, log files and special font characters. Log and trend files can be exported via USB. The NetDCU uses embedded WinCE operation system, therefore the used USB device has to be WinCE compatible (for example: USB1.1). For more information about the downloading of the log files, trends and device information please see Chapter 5.6. The Device ID of the fabian and licenses are stored in the inner memory of the NetDCU, therefore at replacing the NetDCU module, the fabian will get a new device ID (and a new service-password) and the licenses has to be reinstalled as well (See Licensing submenu and License handling, Chapter 6.8.).

4.3.3 Power module The device can be operated from an external power source, but features an internal battery (NiMH Powerpack) also. For detailed description on the topic please read the Battery operation Chapter in the IfU. In this document the power module expression means the sum of the following components: - Power PCB - Powerpack NiMH/ Inner battery - Power supply “XP” - Power inlet module The most important components of the Power PCB are shown in the picture below.
