The PICtail connector right angle header, P2, can plug into 8-bit demonstration and
development boards, such as the PIC18 Explorer Board (DM183032). The PICtail Plus
card edge connector, P1, can plug into Explorer 16 Development Board (DM240001).

PLUGGING INTO THE PIC18 EXPLORER BOARD
The MRF24J40MA/MB PICtail/PICtail Plus Daughter Board can be plugged into the
PIC18 Explorer Board PICtail connector, J3, as shown in Figure 2-1. Make sure to align
pin 1 to RE2 as shown.

Configuring Push Button Switch S2 to RB2/INT2
On the PIC18 Explorer Board, push button switch S2 is normally connected to I/O port
pin RA5. RA5 is not a change on interrupt or external interrupt capable I/O pin. Jum-
pering JP3 with a shunt allows the connection of RA5 to RB2/INT2 to allow push button
switch S2 to trigger an interrupt. Keep in mind that RB2 also connects to pin 10 (input)
of U6 (RS232 level shifter) which is a Clear-to-Send (CTS) signal on P2 pin 8 (DE9
receptacle).
