WARNING
The recommended connector has a built-in terminating resistor. The master module and slave
module also have built-in terminating resistors. Do not turn ON both terminating resistors at the
same time.
Normal transmission is not possible if they are turned ON at the same time.
CAUTION
When routing transmission cable were noise condition is poor, device error may occur due to
noise. Installing the following ferrite core to the connector may improve the situation in this case.
