Debug Header Connections
Contents
The different types of debug header connectors are shown here, as well as information on connecting development tools to the header.
6-Pin Modular Connector
Debug headers with 6-pin modular (RJ-11/ICSP) connectors can connect directly with the following tools:
- MPLAB® ICD 3
- MPLAB® REAL ICE™ In-Circuit Emulator (Standard Driver Board)
Figure: Modular Connection
8-Pin SIL Connector
Debug headers with 8-pin Single In-Line (SIL) connectors are compatible with the tools listed below.
PICkit™ 3 In-Circuit Debugger
The 6-pin socket of the debugger may be connected to the eight header pins by removing the two DAT and CLK pins. However, this may compromise the future use of these pins/functions with other tools.

MPLAB ICD 3 In-Circuit Debugger
The 6-pin modular cable attached to the debugger may be connected to the eight header pins through the Modular-to-SIL Adapter.
MPLAB REAL ICE In-Circuit Emulator
The 6-pin modular cable attached to the Standard Driver Board may be connected to the eight header pins through the Modular-to-SIL Adapter. No SPI trace is available with this connection because of the loss of the DAT and CLK pins.
The 8-pin socket of the High-Speed Driver Board or optional Isolation Unit may be directly connected to the eight header pins. Be sure to line up pin 1 on the board with pin 1 on the header.

6-Pin SIL Connector
Debug headers with 6-pin SIL connectors are compatible with the tools listed below.
PICkit 3 In-Circuit Debugger
The 6-pin socket of the debugger may be directly connected to the six header pins. Be sure to line up pin 1 on PICkit with pin 1 on the header.

SIL Optional Connection
Debug headers with 6- and 8-pin SIL connectors have an additional unpopulated connector available for customer use. This connector has the same pinout as the SIL connector. Solder wires to access individual pins or attach an entire vertical connector.
Figure: SIL Optional Connection
Modular®-to-SIL Adapter
You can use this adapter for a 6-pin modular connector to a 6-pin SIL connector. Ensure that you line up pin 1 of J1 with pin 1 of the 6-pin header connector.
