Selecting connection cable
The Rosemount LinkPro is connected to a power supply with a standard cable that meets local regulatory
standards. RS-485 rated cable with screening should be used to connect the sensors. Screening is
necessary to ensure interference-free operation with other devices. The communication cable should be
twisted pair and shielded, rated for a RS-485 communication standard, and have 120 Ohm impedance.
Cable screening and grounding
The communication cable shield must be grounded. Connect the shield in the Rosemount 5708
grounding point on one end and to a dedicated grounding on the other end. This can be, for example,
the '-' port of the power supply.
