2.1 Triple Modular Redundant (TMR) Description
For 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 executes monitoring voting
using the setup specified in the monitor options. Using this method, the TMR RIM
continually compares a specified output of 3 redundant monitors. If the TMR RIM
detects that the information from one of those monitors is no longer equivalent
(within a configured percent) to the remaining two, it will flag the monitor as being
in error and place an event in the System Event List.
