3.1 Debugger to Target Communication

Important: The MPLAB X IDE software must be installed prior to connecting the MPLAB ICD 4 In-Circuit Debugger.

The debugger is connected to the computer via a USB cable for communication and debugger power (not target power).

The debugger is connected to the target application for communication and data collection. Refer to Connecting an RJ-11 Type Cable to an RJ-45 Jack on the Debugger for pinout information.

The power supply (not included) is connected either to the target application (preferred method) or the debugger to provide power to the target.

The debugger system configurations are discussed in the following sections.
