Table 2-1 : Pin Description 

(Note: CANFDNET-200T integrates two CAN-bus channels,

 

CANFDNET-100T integrates one 

CAN-bus channel)

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.
