PCI 730 & PC104P-30 User Manual

Eagle Technology - Data Acquisition

Analog Out

The PCI730 version has got 4 DAC channels that support single write. The PCI730 has an
output range of +/- 10V and 14-bit resolution.

Writing to a DAC channel

A single call is necessary to set a voltage on a DAC channel.

API-CALL
Long EDRE_DAWrite (ulng Sn, ulng Channel, long uVoltage)

The serial number, DAC channel and micro-voltage is needed to set a DAC channel’s
voltage. A return code will indicate if any errors occurred.

ACTIVEX CALL
Long EDREDAX.Write (ulng Channel, long uVoltage)

The DAC channel and micro-voltage is needed to set a DAC channel’s voltage. A return code
will indicate if any errors occurred.
