Using Cat 5 cable, connect pins 1 & 2 (Blue pair),
4 & 5 (Orange pair), and 7 & 8 (Green pair)
of the CPU 2 to the connecting block.
Using CPU 1 Sync Replacement cable, AWS1154 cut one end off and
connect pins A3 and C5 of the CPU 1
to the connecting block (White/Blue and Blue/White).
Cross-connect CPU 2 to CPU 1 at the block. Measure the delay,
and enter the value in nanoseconds into each slave’s configuration.
