Refer to Figure 4. for the connection diagram for an external analog signal setpoint reference.
Note: When b1-01 = 1 (terminals) and P5-01 = 0 (hand mode reference source), the setpoint and the hand reference are
determined by the external analog signal.

Setting the iQpump drive to receive the “Auto Setpoint” from serial communication: Set b1-01 = “2: Serial Com,” and connect the
RS-485 / 422 serial communications cable to terminals R+, R-, S+, and S- on the control I/O terminal block.
Refer to Figure 5. for the connection diagram using a PC to provide the auto setpoint reference to the iQpump drive. Further information
regarding communication protocols are referenced in Appendix A .
