Off Enables the electronically controlled termination resistor (120 Ω)
for CAN Port 2.
This termination is internal to the 1351, no additional or external
hardware is required.
Cross Connection
CAN_Port_Cross_Connection
0x3004 0x00
Off – Enabled
0 – 1
Off Enable the 2 CAN Ports to be connected together.
Any message received on either Port 1 or Port 2 will be received
by both CAN1 and CAN2. Any message send by CAN 1 or CAN
2 will be sent out both ports. This is often used when CANopen
SRDOs are required in a system.
Note To use this feature, the baud rates of both CAN ports must
be set the same in in order to prevent buss errors and port
shutdowns. The Node IDs of each port must be different.
