Introduction
This instruction manual details the connection and operation of the nXDS pump in its serial control mode. The
parallel, manual and none in control modes are detailed in the nXDS Scroll Pump Instruction Manual (A735-01-880).
The nXDS pump can be connected directly to the RS485 or RS232 serial input on your control equipment or a PC, using
a suitable connector mating half (not supplied). Full serial control is realised by using the following two signal lines:
serial enable and RS232 / RS485 control inputs.
