Other Parts Discussed in Thread: ISO1042
Hi, my customer is using ISO1050 as below: when CAN_RH and CAN_RL is connected together, the 120ohm terminal resistor is connected.
When they test with 9 nodes at 250kbps, the communication is normal. They only connect 2 120ohm termination resistor in.
When they test with 9 nodes at 1Mbps, the communication failed in some of the nodes.
Are there any problem with the circuit above?
How can we find if the problem is caused by hardware or software?
