The daisy chain connection of RS485 network needs to be terminated properly for
uninterrupted RS485 communication. Third-party devices which is integrated may or may
not have onboard termination jumpers — consult the manufacturer’s instructions for
termination information.
If an end device does not have termination jumpers, Emerson / CPC offers a termination
block that can be used to terminate MODBUS network endpoints (CPC P/N 535-2711).
Connect this block just before the end device Fig(iii)and connect the shield to earth
ground, keeping the exposed shield wire length as short as possible (3 inches ideal
maximum length). Alternatively, the last CoreLink in Network can be terminated by
connecting a RS485 termination resistor of Value 150Ω across CoreLink Pin 63, 64 .
