Kit Operation
Figure 4-1 shows connecting two CAN and LIN Shield kits through a DB9 cable. In this figure, the kit
on the left is using CAN1 while the kit on the right is using CAN2. The other transceivers may also be
used by changing the jumper wire connections and DB9 connector used.
Table 4-2 shows the connection details for CAN1 and CAN2 transceivers.

Note: If CAN1 is used on one kit and CAN2 is used on another kit, J10 should be removed on the
kit which uses CAN2.
5. Power up both the Shield Kits using any one of the supply options as explained in 3.6.4 Power
Selection Jumper (J20) . In Figure 4-1 , both the Shield Kits are powered up with different 12 V
supplies.
