JTAG Isolator

The J-Link JTAG Isolator can be connected between the J-Link ARM and any ARM-board that uses the standard 20-pin JTAG-ARM connector to provide electrical isolation. This is essential when the development tools are not connected to the same ground as the application. It is also useful to protect the development tools from electrical spikes that often occur in some applications, such as motor control applications. A 20-pin flat cable (supplied with the J-Link) is needed to connect the target.
