15.1 F IRMWARE E XTENSIONS – O VERVIEW
The firmware installed in a NI is the same for all users. However, extension modules are
supported in the firmware, which will be created to perform specific and dedicated functions.
These extension modules will be activated according to the setting of the FW Config Byte, which is
displayed on the ‘Facilities’ page of ‘NI Engineering’ (see Section 8.2.3 – Facilities ).
The ‘FW Config’ setting is displayed as a hexadecimal byte value and value 0x7FFF is the default
or base setting that does not implement any extension facility. This setting is only programmable
in the factory and, therefore, the user cannot elect to use a particular feature set. The NI will
perform only those duties that the equipment has been built to fulfil, although, when an extension is
enabled, individual items of that feature set may be enabled or not as desired; if none are enabled
the unit will operate as standard.
The configurations available from the NI are listed in order of the ‘FW Config’ byte value in
Table 10 . As more variants evolve they will be added to this document.
