BOARD SETUP

Figure 2-1 is a photograph of the CAN/LIN/J2602 PICtail (Plus) Daughter Board. Call-

outs indicate the CAN bus, LIN bus and signal connections on the daughter board. Also

shown are two 2x15 headers that provide signals from the development board. These

headers can be probed for development, testing or monitoring of the application. For

their specific pinouts, see Section 2.3 "Auxiliary Header Pinouts".

PICtail™ Plus Signal Connector

The daughter board obtains 9V DC input power from either the Explorer 16 Develop-

ment Board through the 120-pin signal connector (J7) or the PIC18 Development

Board through the 4-pin connector (J6) that is part of the PICtail™ daughter board con-

nector on the underside of the board. The power supply to the LIN bus transceivers is

switchable between the 9V available from the development board or an external +12V

supply. This external power supply must be connected to J1. Jumper J2 must be set to

use the required power supply.
