64/80-PIN HEADERS

For these headers, there are no jumpers/switches. MPLAB IDE will use its selected

device to choose the correct device to emulate.

ground.

The PICDEM™ HPC Explorer Board is 5V, whereas the ICD device on the header is

3.6V max. Therefore, modification to the demo board is necessary before the header

can be used.

1.

Switch S3 should be set to ICE.

2.

Jumper J2 must be connected as shown to modify the operating voltage. See

demo board documentation for more information.

Connect the Header and MPLAB ICD 2

Connect the 9-inch modular interface cable between the MPLAB ICD 2 Module and the

MPLAB ICD 2 Header.

Connect the Header and the Target Board

The header may be connected to the target board as follows:

• PDIP header socket to PDIP target socket with a stand-off (male-to-male

connector)

• Header socket to plug on the target board
