INTRODUCTION:
AVR-ISP500-ISO
is professional serial in-system programmer for AVR
microcontrollers, featuring optoisolation between PC and target AVR board.
It implements the STK500v2 protocol as defined by Atmel which makes it
compatible with a range of tools, including
AvrStudio
and
avrdude
.
It is distinguished from other programmers by its support for autonomous
operation. AVR-ISP500-ISO contains a 2Mb FLASH memory where it can
store entire programming sessions, including FUSE, LOCK, EEPROM and
FLASH write and verification, as well as signature checking. Just hold the
button, perform all the necessary steps with AvrStudio, and disconnect the
programmer from the PC. Next time button is pressed the programmer will
invoke all previously recorded steps without the need for connection to the
PC. We believe this feature makes AVR-ISP500-ISO the perfect tool for
firmware upgrades in remote places.

Fully STK500v2 compatible;
Works with AvrStudio, WinAVR, Avrdude and every other software
compatible with STK500v2;
USB port for connection to PC;
Opto-isolation 1000VDC between PC and target AVR board allows
programming of targets under high voltages;
Stand alone operation without the need for PC connection, allowing
firmware mass programming on many devices with single button press;
One bi-color LED for current operation status;
One bi-color LED for last autonomous operation status;
Supports both standard ICSP10 and ICSP6 connectors;
Button for initiating autonomous operations and command logging;
Powered either by USB or external AC/DC power supply;
External clock output on ICSP10 pin 3 for rescuing AVRs with enabled
external clock fuse;
Supports target voltages ranging from 1.8V to 5.5V.
ISP clock frequencies ranging from 5kHz to 1.843MHz.
ELECTROSTATIC WARNING:
The AVR-ISP500-ISO board is shipped in protective anti-static packaging.

PC DRIVER INSTALLATION:
Download drivers for your Operating System from our website. Windows
installation steps are the following:
1. Download and unzip the file “AVR-STK500-ISO-drivers.zip” in a
temporary directory.
2. Plug the programmer in the USB port.
3. Point the Device Wizard to the temporary directory.
4. Click finish.
Screenshots of the steps are shown below:
WARNING:
The COM port number assigned by Windows to AVR-ISP500-
ISO must be COM4 or below. Otherwise AvrStudio might not be able to
detect the programmer. Here are the steps to change it:
1. Go to Device Manager.
2. Unfold “Ports (COM&LPT)” and right-click on “USB Serial Port
(COMxx)” where COMxx can be anything between COM1 and
COM255. Select properties.
3.
Go to the “Port Settings” tab and click the “Advanced” button.
