Hi,

We use 10 boards(S12ZVCA) to send CAN message every 10 seconds. And 1 board(S12ZVCA) to collect those CAN message.

 

It can work fine in 10 meters cable. But it is unstable in 200 meters cable. How to solve the issue? Do you have any recommend?

 

Slew rate: 4

Baud rate: 250kbps

Time segment 1: 4 (We will try "12" on next Monday)

Time segment 2: 1

RSJ: 1

Sample per bit: 3 samples

 

BR, Aaron
