The user need only provide the means to connect the JTAG port of the EC2 serial adaptor to the target (a connector or 4 individual connection points).
The EC2 serial adaptor connects to the PC using a DB9 serial cable (not included), and to a standard Silicon Labs target/prototyping board using a Silicon Labs 10-pin JTAG cable (included). Status LEDs show when power is applied and target RUN and HALT states.
The EC2 serial adaptor measures only 2 3/8 inch x 2 1/4 inch x 1 inch and operates from the target system supply voltage, or from an external 7V to 9V DC supply at 20mA maximum.
