Fig ure 1.2 Ć A Typical FiberĆOptic Cable Remote I/O Network
The type of cable used (whether coaxial or fiberĆoptic) does not affect
the operation of the Remote I/O network protocols, application
software, or the operation of the Remote I/O Communications
module, Shark Interface module, Remote I/O Head, or Remote Drive
Interface Head.
The Remote I/O Communications module in the master drop (drop 0)
rack functions as the network's Remote I/O master. Master or slave
Remote I/O Communications modules may be installed in any slot in
the rack. Any number of Remote I/O Communications modules can
be installed in a master rack, each controllinga separate Remote I/O
network. See figure 1.3.
