The RRC16/RJX port module for RIO includes 16 RS232/RJ45 serial ports in a slim rack mountable unit with an integrated power supply. RIO is a state-of-the-art serial connectivity solution for medium to large scale applications. It provides connectivity for up to 128 serial devices via a single server slot. Up to 512 devices can be attached to a single host using four RIO host cards. Serial port modules can be installed up to 75 meters from the host using twisted pair cabling. The modules can even be daisy-chained to extend the range. Additionally, port modules can be connected up to a mile from the host via fiber optic, or longer distances via leased line, using RIO's unique connectivity modules

RIO supports fault-tolerant cabling, which will re-route data in the case of cable disruption; and for complete data security, supports the connection of a stand-by host in case of a server crash.To enable system administrators to manage sophisticated installations, RIO includes a superb graphical management suite which displays a map of your system and enables configuration and diagnostics down to the individual port level.
