CAN Bus (CN12, CN13)
Two NXP SJA1000 CAN Bus controllers are configurable for BasicCAN and PeliCAN. Another feature is the
flexibility to access the CAN Bus as a socket network device. To configure the CAN Bus, please see “CAN
BUS MODE” on page 28.
The isolated CAN Bus transceivers:
• provide high input impedance for maximum protection in harsh environments. An impedance setting
is built into the board and is enabled when pin 6 LOAD ON and pin 7 LOAD T are connected, and
unpowered nodes do not disturb the bus resulting in secure and reliable network signaling.
• provide up to 2500V channel isolation, maximum speeds up to 1 Mb/s, and slope control to reduce
EMI.
• have thermal shutdown protection.
