EXTERNAL BUS CONNECTIONS
The MCP2515 can be connected to an external CAN bus through the DB9(s). The DB9
pinout is the same as the defacto standard, as recommended by the CAN in
Automation (CiA) group. At a minimum, CANH (pin 7) and CANL (pin 2) must be
connected. However, CAN_GND (pin 3) and CAN_V+ (pin 9) may also be connected
to supply power to and from another board. Table 5-1 and Figure 5-3 show the pinout
and connector, respectively.
