PCA9600 demonstration board OM6293
Ensure that the 5 V power selection jumper is fitted between pins 2 and 3 on header J1 or
that some alternative logic supply voltage is connected to pin 2 on J1 so that there is a
supply voltage for the I
2
C-bus on the Sx/Sy side of this ‘remote’ board. The cable bus
signals will be converted back to conventional I
2
C-bus levels by the ‘remote’
P82B96/PCA9600 and both the cable bus and I
2
C-bus signals are available for probing on
the 8-pin header J2. They are also available on the 9-pin header CON4 in the same
format as on the I2C 2005-1 expansion header.
Note that only the ‘switched 5 V’ supply from the I2C 2005-1 board is used on
CON1/CON2. The un-switched 5 V and 3.3 V supplies are not available on the Cat5e
cable and therefore are not available on CON4 in modes where boards are linked only by
the Cat5e cable.
For further details on this setup, refer to Application Note AN10658, section 3.2.
