Frequently Asked Questions for the I2C2002-1A kit:

Please first review the  I2C2002-1A Quick Start Guide  and the
I2C2002-1A Evaluation Board Appnote   before using your I2C2002-1A kit!

Q: What is included in this kit?
A: The kit contains the NXP (Philips)  I2C2002-1A Evaluation Board (PCAxxx I2C devices), the I2CPortv2.0 printer port
     adapter, and the latest version of Win-I2CNT on CD.
     Cables and a universal-input switching AC power adapter (USA plug) are also included in the kit.

Q: What's the quickest way to get the I2C2002-1A kit up and running?
A: See the I2C2002-1A Quick Start Guide for recommended starting configuration and testing your kit.

Q: Where do I get more technical information for the Philips I2C devices and the I2C2002-1A Evaluation Board?
A: Link to the NXP (Philips)Semiconductors' website for I2C-2002-1A Evaluation Board:
    Link to latest version of the I2C2002-1A evaluation board appnote (instructions and examples):
    Link to NXP Semiconductors' website: I2C Bus specification:

Q: Is a full schematic available for the I2C2002-1A Evaluation Board?
A:  I2C2002-1A_Full-Sch.pdf

Q: What are the USB connectors on the I2C2002-1A 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
     I2C2002-1A Evaluation Board to the "USB Adapter Board" via the P82B96/PCA9600 I2C bus buffer ICs.
   These connectors 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 (LPT) port adapter.

Q: Problems establishing I2C communications through the PCA9600  "USB Adapter Board" ?
A: This board has two positions for the "USB" connector (buffered I2C connection to the I2C2002-1A using a USB
    cable.  If the USB connector is in the "conn1" location, then a jumper must be soldered into the "conn2" tab
    locations as shown in this picture to complete the ground connection.

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.
     If the included I2C cable has guide keys on the 4-pin connectors, the guide keys should be facing the opposite
     side of the DB-25 plug on the I2CPortv2.0 adapter
     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 green LED next to the Power connector should illuminate when power is first applied to the I2C2002-1A board
     (other green LEDs next to the PCA9561 device may also be lit).
     The I2C2002-1A QuickStartGuide outlines the recommended configuration and steps to get the kit running qquickly.

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 I2C2002-1A Kit?
A: See <Help-About> from the main Win-I2CNT menu to verify the installed version.
     Win-I2CNT v4.7 is the current release; newer beta versions may also be available for download.
     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 I2C2002-1A Evaluation Board and associated PCA95xx ICs:
    Technical support for the Win-I2CNT software and the I2CPortv2.0 adapter:

Q: How does the I2C2002-1A  Evaluation Board differ from the earlier I2C2002-1  Evaluation Board?
A: The revised Philips I2C2002-1A Evaluation board is a new PCB that contains the same I2C peripheral devices;
     The I2C2002-1A board incorporates design changes and improvements over the earlier I2C2002-1 design.
