Page 21: Communication Connections
2.5.1 Standard Communication Target Connection Using the RJ-11 connector, the MPLAB ICD 3 in-circuit debugger is connected to the target device with the modular interface (six conductor) cable. The pin numbering for the connector is shown from the bottom of the target PC board in Figure 2-3.
Page 22 ) and 3 (V ) are shown on Figure 2-4 for completeness. MPLAB ICD 3 has two configurations for powering the target device: internal debugger and external target power. The recommended source of power is external and derived from the target application.
Page 23: Debugging With The Debugger
DEBUGGING WITH THE DEBUGGER There are two steps to using the MPLAB ICD 3 in-circuit debugger system as a debugger. The first requires that an application be programmed into the target device. The second uses the internal in-circuit debug hardware of the target Flash device to run and test the application program.

Important Information Concerning the Use of the MPLAB ICD 3 In-Circuit Debugger Due to the special nature of the MPLAB ICD 3 in-circuit debugger, the user is advised that it can generate higher than normal levels of electromagnetic radiation which can interfere with the operation of all kinds of radio and other equipment.
Page 86: Usb Port/Power
ICD 3 In-Circuit Debugger User’s Guide 10.4 USB PORT/POWER The MPLAB ICD 3 in-circuit debugger is connected to the host PC via a Universal Serial Bus (USB) port, version 2.0 compliant. The USB connector is located on the side of the pod.
Page 87: Standard Communication Hardware
The actual power comes from the MPLAB ICD 3 in-circuit debugger system as the V sense line is used as a reference only to track the target voltage. The V connection is isolated with an optical switch.
