The Rack Interface Module (RIM) is the primary interface to the350020-01-02-00rack. It supports a proprietary protocol used toconfigure the rack and retrieve machinery information. TheRIM must be located in slot 1 of the rack (next to the powersupplies).

The RIM supports compatible Bently Nevada externalcommunications processors such as TDXnet, TDIX, and DDIX.  While the RIM provides certain functions common to theentire rack, the RIM is not part of the critical monitoring pathand has no effect on the proper, normal operation of theoverall monitoring system. One RIM is required per rack.

For Triple Modular Redundant (TMR) applications, the 350020-01-02-00ystem requires a TMR version of the RIM. In addition to all thestandard RIM functions, the TMR RIM also performs “monitorchannel comparison.”  The 350020-01-02-00 TMR configurationimplements monitor voting using the setup specified in themonitor options. Using this method, the TMR RIM continuallycompares the outputs from three (3) redundant monitors. Ifthe TMR RIM detects that the information from one of thosemonitors is no longer within a configured percentof theinformation of the other two monitors, it will flag that themonitor is in error and place an event in the System Event List.
