Analog load cell cables cannot be used.

These cables are not designed for serial data communication standards, such as RS-485. Digital load cells use shielded twisted pair cables (duplex communication with 4 wires) for serial data communication.

With digital load cell cables, transmission moves in one direction and DC power (7V to 10V) moves in the other. As cables become longer, one must check for voltage drops in the DC power to ensure that the specified voltage is applied to the digital load cell.
