USB-2-I2C

Conversion Kit for HDJD-JD13

Operating Hardware Manual

Introduction

The USB-2-I2C kit is a simple conversion board, which
allows USB connectivity for existing Illumination & Color
Management (ICM) development kit that uses parallel
port interface to connect to an IBM-PC computer. This
conversion board doesn’t need any new USB driver to
work since the driver is come pre-installed in Windows
2000/XP operating system.

The USB-2-I2C conversion kit comes with the following:

• USB-2-I2C Conversion Board (Figure 1-1)

• Parallel port conversion cable

• USB cable

• USB-2-I2C Conversion Kit Operating Hardware Man-

ual

• CMS Program (V1.5.0) for communicating with HDJD-
J822

• CMS Program (V2.1.0) for communicating with ADJD-
J823

If you are missing any part of the kit, please contact your
nearest Avago Technologies sales oce listed in the back
of this publication for help.

USB-2-I2C Conversion Board

The USB-2-I2C conversion board has the following hard­ware features:

1. USB port and associated hardware for direct connec­tion to an IBM-PC computer USB port

2. 5V to 3.3V voltage level shifter IC

3. Micrcontroller for USB to I2C data transfer

4. Jumper to select either using USB +5V or external
+5V

5. PCB mounting socket for external +5V supply

6. PWM Flex connector that connects to external LED
driver

7. HDJD-JD04 Flex Connector that connect the HDJD­JD04 exible circuit board

8. PWM header pin that connects to external LED
driver

9. General purpose external I/O connector to connect to
the unused I/O port of the onboard microcontroller

10. I2C interface that connects to existing ICM develop­ment kits that needs USB connectivity. This interface
