Labview with LTC6811 BMS Daisy Chain Issues

Question

Hi, im trying to build a BMS by using 2 ltc6811-1 boards and daisy chaining them together. I am confused as to how the isoSPI works. For the first board which is connected to my controller, i am using the 14-ribbon SPI. For the connection of the bottom board to the top board i am using the RJ45 cable provided. In my Labview program, i am unsure of how to wake up the second board. My current program is able to read up to 12 cells but I am looking to further expand its capabilities. From what i can understand, the isoSPI port takes 600us to wake up and be at the ready state. I would have to wake up the isoSPI port before sending the read configuration command? x0002.

The order of bytes should be as follows: [Toggle CS, wait 600us, CMD1, CMD0, CPEC 1, CPEC 0, D0, D1, ..., Dx, DPEC0, DPEC1 , D0, D1, ..., Dx, DPEC0, DPEC1 ] 
 If a read command the red is data read from device 0, blue data read from device 1. For more than two devices any further data read will be for the next device up the daisy chain. 
 If a write command the same order applies but the red data sent first goes to device 1, the blue data to device 0. Any further data sent will push the red data to the next device up the daisy-chain.)
