2.1.3 How to set jumper blocks on I/O Board
How to set the termination resistors
Use the jumper blocks JP1 to JP4 on the I/O Board (24P0124) to set the termination
resistors for J3 to J6 ON or OFF. The default setting is ON.
• When setting the starting/ending terminal for the multipoint connection, or multipoint
is not connected (CH1 to CH4): termination resistor ON
• When not setting the starting/ending terminal for the multipoint connection (CH1 to
CH4): termination resistor OFF
