2.2.1
Explorer 16 Board PICtail connector J1 (see Reference 1) is a 120-pin signal
connector that carries signals from the I/O pins of the dsPIC33F or PIC24 device on the
Explorer 16 board to the ECAN/LIN PICtail Plus Daughter Board. This connector
handles the following signals:
• 9V, 5V and 3.3V DC input to the ECAN/LIN PICtail Plus Daughter Board
• Signals from the ECAN modules on the dsPIC33F or PIC24 device to the CAN
• Signals from the UART modules on the dsPIC33F or PIC24 device to the LIN
• LIN Bus Fault Communication
2.2.2
Auxilliary Headers J2 and J3 (see Reference 2) make available a various set of signals
from the Explorer 16 Development Board. These headers can be used for monitoring,
testing and development purposes. Refer to the Board schematic for more details of
these headers.
2.2.3
The LIN1 and LIN2 Bus Master/Slave Select Jumpers (see Reference 3 or
Reference 7) are used to indicate the presence of a master device on the LIN Bus.
Placing jumper J13 or J12 pulls the LIN Bus high via a 1K pull-up resistor. This can be
detected by nodes on the LIN bus as an indication that a Master node is present. There
can be only one Master node on a LIN bus.
2.2.4
A set of MCP2021 LIN Transceivers (see Reference 8 and Reference 4) provide the
interface between the UART modules on the dsPIC33F or PIC24 device and the LIN
bus. The transceiver converts the signals from the UART modules on the control device
to a 5V regulated signal for the LIN Bus. The power supply to the LIN Transceivers is
selectable between +12V or +9V with jumper J8 (see Reference 6). While the +9V is
available from the Explorer 16 Development Board, the +12V supply must be
connected externally to J9 (see Reference 10).
2.2.5
The LIN1 and LIN2 Bus Connectors are 3-pin terminal blocks that connect the
ECAN/LIN PICtail Plus Daughter Board to a LIN Bus. LIN1 connector J10 (see
Reference 9) connects UART1 module on the dsPIC33F or PIC24 control device to the
LIN Bus via the LIN1 Transceiver. LIN2 connector J11 (see Reference 5) connects
UART 2 module on the dsPIC33F or PIC24 control device to the LIN Bus via the LIN2
Transceiver.
2.2.6
This 3-pin jumper (see Reference 6) selects the power supply to LIN Transceivers U1
and U2. Either +9V DC is supplied from the Explorer 16 Development Board or +12V
DC is supplied from an external power supply connected to J9 (see Reference 10).
2.2.7
External +12V DC power for the LIN transceivers must be connected to J9 (see
Reference 10).
