PDIUSBH11A/H12/D12 Evaluation Kit: User Manual
Introduction
This demo kit uses the PDIUSBH11A (H11A) hub device. The Rev 1.1 Kit precedes the
previous release with added functionality and fixes that will be explained in the later part
of this application note.
Functionality has been expanded such that the same Hub board can be used to
implement a USB Hub with Monitor control system. The USB Monitor Control system,
classified under a HID device, is implemented using the embedded function of the
H11A. However, the usage of the embedded function of H11A is not exclusive to
Monitor Control.
The firmware to control the H11A is backward compatible to the H11 except for some
minor changes to fully utilize the new features of the H11A.
Features
This release of the Philips Hub contains the following items:

4. INDICATORS
See table below for the list of LED indicators
Name
LED1 (red)
Description
This LED indicates that the downstream ports are powered.
Upon proper configuration of the Hub, this LED should be
lighted to indicate that the downstream are powered
properly.
LED 2 indicates that the downstream port 2 is enabled.
Whenever downstream port is attached and a proper port
detection is done, the downstream port is enabled. If the
H11A is in GoodLink
TM
mode, this LED blinks when traffic is
detected via Port 2.
same as LED2 except that they correspond to downstream
ports 3 to 5 respectively.
LED2 (green)
LED3 -5
(green)
There are two DIP sockets for the 51 family of micro-controllers, they are the DIP24 and
DIP40. Either one can be used.
DIP24 : 83C748/87C748 (2K EPROM/ROM, 64 RAM)
83C751/87C751 (2K EPROM/ROM, 64 RAM)
DIP40 : Generic 80C51 (4K ROM)
The above is not an exhausted list. The only consideration would be the ROM size
required for the application.
VGA Passthrough Module
This module acts as a pass through for the
normal VGA signals. The wiring for the
DDC2B+/2AB monitor control protocol is tapped
and routed to the micro-controller via JP2. To
use this module, insert it on JP2 of the main
board.
