DEF+
When DEF+ and DEF- are short-circuited, the parameters of Ethernet
and CAN saved in CANFDNET-100T/200T module will be changed to
default if you restart the CANFDNET-100T/200T module (see Figure
2-4).

2.2 CAN bus connections
To connect CANFDNET-100T/200T module to the CAN-bus, user only need to connect CAN_H and
CAN_L, CAN-bus network adopts straight-line topology, and two terminal 120Ω resistances need to be installed
on the two bus terminals. If the number of odes larger than 2, the 120Ω resistance is not necessary to be installed
on the middle node. The length of branch connection should not be longer than 3 meters. The connections for the
CAN-bus are shown in Figure 2-3.
