Reset Bus (RB)

Setting bit 3 will set the internal RB line true. Setting bit 19 will set the internal RB line false. Setting bit 1 will direct the RB to the crate segment, bit 17 will direct the RB to the cable segment. This allows the cable segment to issue a RB into the crate segment through the SSP. Setting bits 1 and 3 from the cable segment will set RB in the crate. Setting bit 19 will drop the RB in the crate. A jumper on the control board controls whether setting bit 3 generates a pulse on RB or a level.
