WARNING.
Improper Connection
The internal LON connection is for use
with internally mounted and powered
Analyzers only. Using this connection
for external Analyzers or LON compo-
nents could result in short-circuiting
the 24V Power Supply Module through
the cable, with resultant damage. Use
the LON I/O board for external Ana-
lyzer module connections (see Section
1-10c).
d. Distribution Assembly Components
The Backplane is the backbone of much of
the NGA 2000 Series' modularity. The Con-
troller Board, Power Input Module, Power
Supply and I/O Modules all plug into the
Backplane. Identifying ground pins allow I/O
Modules to identify their slot position.
NOTE
Earlier I/O Modules did not support
slot identification. If so they will indi-
cate slot 0 no matter where they are
placed.
