The function of the "relay matrix" is not described there, either.

                           None of this makes sense!            01/01/70 00:00      
                           It appears you need latching relays            01/01/70 00:00      
                              Latching relay is still slow            01/01/70 00:00      
                                 You're right, but the relay spec's should reveal that            01/01/70 00:00

                                 use toggle types ... they were around once ...            01/01/70 00:00      
                                    SPI + latched shift registers are good choices            01/01/70 00:00      
                                       The protocol is good ... but not necesary here            01/01/70 00:00      
                                          SPI is excellent for driving long shift registers            01/01/70 00:00
