Note (1*): These are for thick cables. Keep the maximum length to 100m or less when using thin cables.
CAUTION:
Baud rate must correspond to the connecting DeviceNet unit. If they do not
correspond, communication will become unstable and a link may not be
established correctly.
Upon selecting the network cable, consider the ambient conditions such as
noise and temperature.
