1. Install USB driver of PX-4000
(1)Double-click at the USBDriverInstallerV2.0.0.exe file from PX-4000 CD-ROM.
The driver installation begins and the Installation complete dialog will appear after finish.
Troubleshooting USB Driver Problems
To use INEXís USB-based products, the proper FTDI USB drivers need to be installed on your
computer system first. INEX supports the FTDI USB VCP Drivers for Windows 2000/XP. For other operating
systems you may obtain drivers from the FTDI website at http://www.ftdichip.com.
IF, after installing the correct USB drivers for your operating systems, you have problems
communicating with your USB device, refer to the troubleshooting advice given below.
Communication Issues
Most laptop computers and some desktops have issues with USB Latency when it comes to
communication. When this happens the port will show up in the list but you may not be able to
identify or communicate with your USB Device. This may require the Latency Timer Setting in the
Device Manager to be set lower. To lower the Latency Timer settings please follow the steps below.
The USB Device should be plugged in to adjust these settings.
Reducing The Latency Timer Setting
l Click on your Start Button and select Control Panel
l Open the ëSystemí icon (you may have to be in classic view to see this icon)
l Select the Hardware Tab and click Device Manager
l In the hardware categories you should see a Ports Category, click the plus sign next to it
l You should see an entry for USB Serial Port (COMx) where x is the COM Port assigned to the
USB Adapter
l Click this entry and then click Properties (or double-click the entry)
l Select the Port Settings Tab and click AdvancedÖ
l Under BM Options reduce the setting from 16 down to 1 and click OK
l Click OK on the properties sheet and close the Device Manager window
l If, when you connect your hardware, Windows pops up with a New Hardware Wizard
this could be for one of two reasons.
- The driver did not register during installation. If this is the case then simply follow the
new hardware wizard by following the default selections and selecting automatic installation.
- There is a problem with either the Interface and/or the computer. If you continue
to have problems please contact our Tech Support Department.

(2) Connect USB plug pf PX-4000 to computerís USB port. Wait a moment.
The blue LED indicator will lit. Now the PX-4000 ready to use.
(3) Check the COM port address by clicking at Start à Control Panel à
(4) Select the Hardware tab and click on the Device Manager button.
(5) Check the hardware listing. At the Port item, you will found USB Serial
port (COM x).Normally the address will be COM3 or higher. Note this COM port address
to use with the programmer software later.

2. Software Installation
Programming in the AVR microcontroller development is in both C and Assembly
languages. The software that are installed for programming are the following :
(1) AVR Studio : This software tool is developed by Atmel Corporation. AVR Studio
is a Development Tool for the AVR microcontrollers. AVR Studio enables the user to fully
control execution of programs on the AVR In-Circuit Emulator or on the built-in AVR
Instruction Set Simulator. AVR Studio supports source level execution of Assembly
programs assembled with the Atmel Corporationís AVR Assembler and C programs
compiled with IAR Systemsí ICCA90 C Compiler for the AVR microcontrollers and WinAVR
open-source C Compiler. AVR Studio runs under Microsoft Windows95 and Microsoft
Windows NT. Now Windows XP SP2 is recommended. Free download this software at
(2) WinAVR : WinAVR is a set of tools for the C compiler, these tools include avrgcc
(the command line compiler), avr-libc (the compiler library that is essential for avrgcc),
avr-as (the assembler), avrdude (the programming interface), avarice (JTAG ICE
interface), avr-gdb (the de-bugger), programmers notepad (editor) and a few others.
These tools are all compiled for Microsoft Windows and put together with a nice
installer program. Free download of the updated version is located at : http://
User will need to install AVR Studio first and WinAVR after which. AVR Studioís
mechanism integrates automatically with WINAVR. With this feature, it assist the user in
the development of C language and programming on AVR Studio which is much easier
and more powerful compared to WinAVR. The compiled file is a HEX file in which case,
the user has to download it into the program memory of the AVR microcontroller Board.
(3) Programmer software : This software is used to download the compiled .HEX
file to the AVR Microcontroller. Included in PX-4000 programmer is the AVRProg and
AVR-OSP II. All software can work with PX-4000 via Computer USB port.
(3.1) AVR Prog is Atmelís software and an add-in feature in AVR Studio.
(3.2) AVR-OSP II is created by Mike Henning. Download the latest version
at http://esnips.com/web/AtmelAVR
