Figure 12 – CAN Node Detached from AOAA Board
There is a possibility to extend the CAN network via either a DSUB9 (J6) or RJ45 (J5) connector.
These connectors are not mounted but can easily be soldered, if needed. The connectors follow
standard CAN pinning, see tables below.
The CAN interface connectors on the LPC11C24 node are overlapping. Only one type of connector at
a time can be used.
The CAN network can be extended via normal Ethernet (cat 5 or cat 6) or DSUB-9 cabling.

Figure 13 illustrates how the CAN node can be removed from the AOAA board. An Ethernet cable and
RJ45 connectors are used to create the CAN network.
