Board Address
The MASTER board should be at one end of the Ethernet cable for proper operation of
the I²C-bus. Subsequent SLAVE boards are not required to be in any certain order. Also,
there may be gaps in the SLAVE board addresses (e.g., it is possible to have SLAVE
Boards 2, 4, 6 and no SLAVE Board 3 or 5).
Cable LED OEn
This switch connects the OEn of the PCA9633 to pin 6 of RJ45 cable so that the master
board can control the PCA9633 /OE pin on each slave board. This MUST be set to ON
for proper operation.
