DAC Pump(s)

The DAC Pump(s) driver allows you to control voltage-controlled low-pressure pumps for which a separate device driver is not available. A Dionex 12-Bit DAC card is required for this. (For installation instructions, refer to Hardware Installation  Installing the 12-Bit DAC Card ("Pump DA Converter") in the Administrator Help section.)

The solvent composition is defined in the PGM File, as a percentage at the respective retention time. On the DAC FlowA tab page in the Server Configuration program, define the voltages that correspond to the minimum and maximum flow of the corresponding component.
