6.4 Communication
CAN
2 CAN 2.0B port, protocol SAE J1939
Auto-Baud-Rate-Detection
400VDC isolation
The two CAN channels are fully isolated from one another in the hardware which
allows for different CAN networks to be connected. In the software, each will also
act independently where incoming or outgoing messages can be configured to
receive or send on a specific CAN channel.
Network Termination
According to the CAN standard, it is necessary to terminate the network with
external termination resistors. The resistors are 120 Ohm, 0.25W minimum,
metal film or similar type. They should be placed between CAN_H and CAN_L
terminals at both ends of the network.
Ethernet
1 port 10/100 Mbit Ethernet compliant
10BASE-T. 100BASE-Tx (Auto-configuration and full-duplex is supported.)
Auto-MDIX
Modbus TCP/IP
