Identifying the boards Each board of the 725X is identified: · by its Code (950..), which is always indicated on the printed circuit, and its description, which is indicated on a label affixed to the handle or the printed circuit · by the Serial Number, indicated on a label affixed to the handle or the printed circuit · by the Configuration Index (CI), also on a label affixed to the handle or the printed circuit · by its Firmware (FW) level (when applicable), displayed in the System Configuration screen, Firmware Option (see next paragraphs) The Configuration Index represents the HW level of the board and is indicated by two decimal figures: CAD-KAS PDF-Editor (http://www.cadkas.com). Changed with the DEMO VERSION ofthe label will therefore be marked CONF.NN. Board Configuration Index and Firmware Level When the CPU is switched on, it reads these values: the results of this reading is, in fact, displayed in the Configuration screen, Boards and Firmware options (see next paragraph). The Firmware is memorised on Flash EPROMs and it is updated via Floppy disk. The Configuration index is memorised on the board on different supports. Some boards have this value memorised on the EPROMs or on a PAL, the next table details which boards use these supports.

If the support is a Flash EPROM or an EEPROM, the index will be updated via Floppy disk. Moreover the CI has to be set via a specific Service menu (see Chapter "Configuration and Calibration procedures") In all the other cases the support will be replaced during updating: excep
