About the RIO system
RIO is a high throughput serial connectivity system which provides up to 128 serial devices
via a single server slot. You can expand a RIO system up to 512 ports per server. RIO allows
you to add ports using 8 and 16 port modules which can be supplied with a wide range of
serial interfaces. The RIO system has fault tolerant capabilities, and allows long distance
connection without signal degradation or performance loss.
A typical RIO system is shown in the next picture. For details of the main RIO system
components, see
You use RIO when you need a system which supports fault tolerant cabling. The RIO system
allows you to add and remove port modules while the system is “live”, which means you can
reconfigure without interrupting operations. The relocated units retain their original port
names and settings. This capability is especially useful in the case of cable disruption, and
also for situations where complete data security is required. In addition, RIO supports the
connection of a stand-by host in case of server crashes.
You also use RIO because you require a system that allows long distance connection without
signal degradation or performance loss. RIO allows you to install port modules up to 75
metres from the host card using twisted pair cabling. Furthermore you can extend the range
by daisy chaining devices. In addition, you can connect port modules up to 1Km from the
host via copper wire or fibre optic, or longer distances via leased line, using RIO connectivity
modules.
You use RIO where you need a system that you can reconfigure live without interrupting
system operation. This capability is typically used in environments such as manufacturing
plants, test suites and hospitals.
