CJ-series User Defined CAN Unit Operation Manual for NJ-series CPU Unit (W517)
The two 10-position rotary switches below the Unit No. are reserved for future use.
The DIP switches on the front of the User Defined CAN Unit are used to set the baud rate and implicitly,
the sample point. The baud rate is set with switches 1, 2 and 3. Switch number 4 is reserved for future
use.
The settings of the DIP switch pins for the baud rate are shown in the following table. All pins are set to
OFF at the factory.
Note
*Sample point is reduced due to the clock frequency.
Precautions for Safe Use
Always turn OFF the Controller before changing the DIP switch settings.
Precautions for Correct Use
Precautions for Correct Use
Set the same baud rate on all of the nodes in the network. Any unit with a baud rate different
from the other units’ baud rate won’t be able to participate in communications and may cause a
communications error between units that have been set properly
