Addressing of
DNR-12-1G
Components
A feature of the DNR-X-1G design is that the address of a module is determined
by the position of the module within the enclosure, numbered from left to right. A
typical module address is:
0xA00nxxxx
where A00 is the BASE address
n is the module position number starting from 0 at the left
xxxx is the address of the module
With this addressing method, the address of a given I/O board (module)
automatically changes if you move it from one position to another within the
enclosure.
The slots or module positions are numbered as follows (left to right):
