-To connect Isolated SPI1 as a master, connect jumpers JP5, JP7, JP9, JP11, JP13, JP15, JP21 and JP36 while leaving jumpers JP6, JP8, JP10, JP12, JP14, JP16, JP20 and JP37 open. To connect Isolated SPI1 as a slave, connect jumpers JP6, JP8, JP10, JP12, JP14 and JP16 while leaving jumpers JP5, JP7, JP9, JP11, JP13 and JP15 open. When connecting SPI1 as a slave JP20 should also be connected, enabling the slave select and serial clock inputs on the [[http://www.analog.com/adum3402|ADuM3402]].+To connect Isolated SPI1 as a master, connect jumpers JP5, JP7, JP9, JP11, JP13, JP15, JP21 and JP36 while leaving jumpers JP6, JP8, JP10, JP12, JP14, JP16, JP20 and JP37 open.
