Please review the I2C2002-1 Evaluation Board Appnote before using your kit!
Q: What is included in
this kit?
A: The kit contains the
Philips I2C2002-1 Evaluation Board (PCA85xx I2C devices), the I2CPortv2.0
printer port
adapter, and the latest version of Win-I2CNT on CD. Included on the
CD are the Philips Application Notes for
the IC devices supported on the I2C2002-1 Evaluation Board. Cables
and the AC power adapter are also included.

Q: Where do I get more
technical information for the Philips I2C devices and the I2C2002-1 Evaluation
Board?
A: Link to the Philips
Semiconductors' website for datasheets and appnotes: http://www.philips.com/i2clogic

Q: Is a full schematic
available for the Philips I2C2002-1 Evaluation Board?
A: I2C2002-1_Full-Sch.pdf
Q: What are the USB connectors
on the I2C2002-1 Evaluation Board and the small "USB Adapter Board" ?
A: These connections
are NOT for "USB", but allow using a common USB cable to connect buffered
I2C from the
I2C2002-1 Evaluation Board to the "USB Adapter Board" via the P82B96 I2C
bus buffer ICs.
These
connections should NEVER be mistakenly connected to a
PC USB port or USB peripheral!
The only possible I2C connection to your PC is through the I2CPortv2.0
parallel (printer) port adapter.
Q: "SDA Stuck Low" error
message results from Win-I2CNT menu when any I2C communication is attempted.
A: Make sure the 4-pin
I2C cable is properly connected between the I2CPortv2.0 adapter and the
I2C2002-1 board.
Disconnect the I2C cable from the I2CPortv2.0 adapter and read the 256x8
EEProm to verify adapter & software
functionality. This error message may also result if the connected
I2C2002-1 eval board is not getting 9v power.
The six green LEDs next to the PCA9561 should illuminate when power is
first applied to the I2C2002-1 board.
Q: Reading the LM75A temperature
sensor(s) does not reflect any temperature changes in the Win-I2CNT display.
A: Make sure one of the
two channels of the PCA9543 (2:1 I2C Mux) has been programmed to select
the desired
LM75A temp sensor IC.
Q: Where do I find additional
information regarding the Win-I2CNT software and I2CPortv2.0 printer port
adapter?
A: Refer to the
Win-I2CNT
FAQ page.
Q: I want to write my
own I2C software in Visual Basic, C++, Delphi, etc. Are the drivers
and examples available?
A: The Win-I2CNTDLL
kit provides this capability.
Q: How do I determine
whether or not I have the latest version of Win-I2CNT for the I2C2002-1
Kit?
A: See <Help-About>
from the main Win-I2CNT menu to verify the installed version.
Win-I2CNT v4.2 is the the newest release and can be downloaded from our
website;
Refer to your kit documentation or view the <Regformxx.txt> file in
the Win-I2CNT installed directory of your HDD.
Q: Who do I contact for
technical support?
A: Technical support
for the I2C2002-1 Evaluation Board and associated PCA95xx ICs:
i2c.support@philips.com
Technical
support for the Win-I2CNT software and the I2CPortv2.0 adapter: support@demoboard.com
Known issues with the I2C2002-1 Evaluation Boards:
1) The 2-position
"GPIO" DIP switches next to the PCA9501 and PCA9554 appear to be stuck
in the "off" position.
These
two switches were intentionally fixed (glued) as they do not influence
the GPIO pins of these ICs.
The GPIO pins for these ICs can be controlled externally from the headers
next to each device.
2) The 3.3v and
5v supply voltages measure a little high.
The
Vadj resistor values for the two LM317 regulators may be incorrect and
can be reduced to correct this problem.
Replace the existing Radj resistor values: R18 (27k) with 22k
and R20 (15k) with 12k.
Or, replace all four existing resistors with new values (divided by 10:
R17=910, R18=2.7k, R19=910, R20=1.5k).
!! Do not apply power to the board without R17, R18, R19, and
R20 resistors in place !!
