The input/output conditioning is managed by the Type B /wiki/spaces/OP5367/pages/29360437OP5369 module.
A CPLD is used to configure the fault insertion unit (FIU) section and the OP5367. It is responsible for the communication of the SLSC card within the NI environment for identification, error reporting, etc. It also receives configuration from the software and applies it to the FIU and to some of the I/Os.
The FIU specification and topology are common to all OP8900 boards.
