The Atmel JTAGICE mkII unit requires that a front-end debugging environment (Atmel Studio, AVR32 Studio, or AVR Studio 4.9 or later) and associated utilities are installed on your computer. For system requirements of these packages, consult www.atmel.com.
The JTAGICE mkII unit must be connected to the host computer using either the USB or RS-232 cable provided. Functionality of the two connection options is identical.
The JTAGICE mkII unit may in addition be connected to a 9-15V DC external power source. A cable is included in the kit. If the external power supply is connected, USB power will not be used.
