INSTALLATION OF PDIUSBD12 EVALUATION BOARD
Introduction
The PDIUSBD12 evaluation kit uses 2 PC as a complete USB development environment, a host PC
with USB host capability and a device PC running PDIUSBD12’s firmware. The PDIUSBD12 ISA
bridging board is plugged inside the device PC and connects to the evaluation board using a 25-wire
cable. So the device PC behaves as a big USB device.
Features evaluation of PDIUSBD12, firmware and product prototype development can be easily done
with this setup, without the resource limitation of a micro-controller. Customers can also connect the
evaluation board to their own CPU and bus through the 25-wire cable for final product development.
The firmware is carefully developed for high rate data transmission and is written in C, that supports
Borland Turbo C for x86 and Keil C51 for 8031 currently. Supporting to other CPU platforms will be
available soon.
System Requirements
1. PDIUSBD12 evaluation board and ISA bridging board;
2. 25-wire shielding data switch cable;
3. Host PC with USB motherboard or add-on card;
4. Microsoft Windows 98 or Windows NT 5.0 Beta 2;
5. Device PC running Microsoft DOS 6.x;
6. PDIUSBD12 evaluation diskette.
For firmware development:
1. X86 CPU platform: Borland Turbo C++ 3.0 or above;
2. 8031: Keil C51 4.0 or above.

Installation
Jumper’s setting on PDIUSBD12 ISA bridging board
The PDIUSBD12 ISA bridging board is plugged inside the device PC. It will occupy I/O, IRQ and DMA
resources of the device PC. To avoid possible conflicts in settings, we suggest removal of all the
unnecessary cards from the device PC. Sound card and network card may cause conflict in IRQ and
DMA setting.
Switch S1 sets the base I/O address for the D12 evaluation board. Default base address is 0x368.
The D12 evaluation board occupies 8 I/O locations. A0 to A2 are decoded on the D12 evaluation
board. Switch S1 sets the address decoding of A3 to A9. Please notice that a switch ‘ON’ is logic ‘0’.
SW(n) 12345678

Default OFF OFF ON OFF OFF ON OFF OFF
Jumpers JP1 and JP2 set the IRQ number for the D12 evaluation board. Default setting is IRQ5 or
JP1 is shorted.

Jumpers JP3 to JP6 set the DMA number for the D12 evaluation board. Default setting is DMA3 or
JP4 and JP6 are shorted. Please note that a respective pair of jumpers is needed to set a particular
DMA channel.

Possible conflict table:
IRQ or DMA
Number Possible Conflict
IRQ5 Creative SoundBlaster™ and compatible sound cards always occupy
this IRQ by default. If this kind of sound card is installed, you should
check its settings or remove it.
Some network cards may also use this IRQ.
IRQ7 Used by parallel port by default. May cause printing problem on
device PC.
DMA1 Creative SoundBlaster™ and compatible sound cards always occupy
this DMA by default. If this kind of sound card is installed, you should
check its settings or remove it.
DMA3 No conflict.

Installation of firmware, INF and driver
The firmware, D12FW.EXE, runs on the device PC under DOS mode. When D12FW starts, it lights up
test LEDs on the evaluation board for 1 second. This means that the I/O address setting is correct.
And the evaluation board is disconnected and re-connected to USB by SoftConnectTM. If this is the
first time that the evaluation board is connected to host PC, host OS Device Manager will prompt
installation of INF and driver. Select the location of D12TEST.INF and D12TEST.SYS and complete
installation procedure.
Some useful key command is supported when the firmware is running.
Key Operation
ESC Disconnect USB and quit PDIUSBD12 firmware.
ENTER Reconnect USB using SoftConnectTM.
iDisplay firmware status information.
vSwitch on/off verbose mode, normally turned off for faster operation.
Using the Host Applet
The test applet, D12TEST.EXE, exercises all PDIUSBD12 endpoints. Testing of control endpoints can
be further done by standard USB Chapter 9 test programs.
The operation of each endpoint is designed according to its nature that is supported in PDIUSBD12.
Generic in and generic out endpoints has max packet size of 16 bytes and supports I/O access only.
So they are suitable for small size and low rate data transfer like keyboard and logic controls. The
main endpoints have max packet size of 64 bytes or 128 bytes with double buffering and DMA
support. So they are suitable for high data rate, large size data transfer.

See the table below for the description of endpoints operations on PDIUSBD12 evaluation board.
Endpoint
Number Endpoint Type Operations
1Generic
In This pipe is defined as Interrupt In pipe. The PDIUSBD12 evaluation board sends key press/release data packet to the host when test keys
are pressed or released. The firmware uses I/O accesses on this
endpoint.
1Generic
Out This pipe is defined as Interrupt Out pipe. Data packet received from host is interpreted as LED control and the D12 evaluation board
firmware will light up the corresponding LED. The firmware uses I/O
accesses on this endpoint.
2Main In
Main Out These pipes are defined as Bulk In/Out endpoints. Test applet and the PDIUSBD12 evaluation board supports 3 test modes: loop-back mode,
print mode and scan mode. The firmware uses DMA for data transfer
on these endpoints.
Main endpoints support 3 different test modes:
1. Scan mode: The PDIUSBD12 evaluation board acts like a scanner. It sends data packets to the
host PC as fast as possible. This mode is used to evaluate the maximal Bulk In transfer rate.
2. Print mode: The PDIUSBD12 evaluation board acts like a printer. It receives data packets from
the host PC as fast as possible. This mode is used to evaluate the maximal Bulk Out transfer rate.
3. Loop back mode: In this mode, the PDIUSBD12 evaluation board receives data packets on Main
Out endpoint and sends them back to the host PC on Main In endpoint. This mode is used to test
the data integrity of transfers.
The “Buffer Size” setting on the test applet is determined by the firmware and hardware ability of the
evaluation board. For PC kit, the maximal size is limited to 64000; On USB-EPP kit, this is limited to
16384.
The “Repeat Times” for loop-back test controls the numbers of iterations of loop-back, which is useful
for debugging. “-1” means it is infinite.

HARDWARE DESCRIPTION
Block Diagram
Above block diagram shows 5 main components on the PDIUSBD12 evaluation board. Beside bus
transceiver, address/command decoder and PDIUSBD12, a general input port and a general output
port are included in the design. These input and output ports are designed for test purposes, such as
test switches and test LEDs. They also act as glue logic to adapt the PDIUSBD12 to the ISA bus. For
example, ISA interrupt is edge triggered, but PDIUSBD12 interrupt is level triggered. The MSB of the
general output port is used as interrupt enable to convert level triggered interrupt to edge triggered.
I/O Mapping
PDIUSBD12 evaluation board uses 8 I/O addresses:
