CAUTION
1. Set and keep "OSEN" on the DIP switch to OFF. Setting it to ON can get failed or
malfunctioned.
2. When you set "BUSOFF" on the DIP switch to OFF, transmission will restart automatically
even when busoff occurs. Unless the cause of the DN211's busoff (cause of communication
error) is solved, however, busoff may get repeated.
3. When you set both of communication rate DR0 and DR1 to ON and turn on the power of the
T2/T2E/T2N, "Communication Rate Setting Failed" will appear with the following
indications:
• The "MS" LED is blinking red.
• "F7" and the local station node address are being displayed alternately on the 7-segment
LED.
To clear these indications, set DR0 and DR1 correctly and, issue a reset request or turn
OFF and ON the power.
4. Set the communication rates of your nodes being connected to the network, to the same
communication rate. Setting different communication rates on your different
nodes will cause slave devices or the DN211 to get malfunctioned, resulting
in no communication started.
Read the relevant manuals and descriptions to set the communication rate of your slave
devices.
5. Don't change over the communication rates while your T2/T2E/T2N is rising just after the
turning on the power. In particular, never change the communication rate while
communicating with slave devices. Failing to do so will cause "Communication Rate Setting
Failed" to appear.
To clear this indication, set the DIP switch to the correct setting and, issue a reset request
or turn OFF and ON the power.
Usage Recommendation
1. Use a small minus screwdriver for changing the value of the DIP switch.
