Bently Nevada 3500/20 Rack Interface Module with RS232 Serial Communications and Hayes AT-Compatible

The Rack Interface Module (RIM) is the primary interface to the Bently Nevada™ 3500 rack. It supports a proprietary protocol used to configure the rack and retrieve machinery information. The RIM must be located in slot 1 of the rack, next to the power supplies. It also supports compatible Bently Nevada external communications processors such as TDXnet, TDIX, and DDIX. While the RIM provides certain functions common to the entire rack, it is not part of the critical monitoring path and has no effect on the proper, normal operation of the overall monitoring system. One RIM is required per rack.

For Triple Modular Redundant (TMR) applications, the 3500 System requires a TMR version of the RIM. In addition to all the standard RIM functions, the TMR RIM also performs monitor channel comparison. The 3500 TMR configuration implements monitor voting using the setup specified in the monitor options.

Using this method, the TMR RIM continually compares the outputs from three redundant monitors. If the TMR RIM detects that the information from one of those monitors is no longer within a configured percent of the information of the other two monitors, it will flag that monitor as in error and place an event in the System Event List.
