SonixDAQ Hardware

The SonixDAQ box contains:
 * The SonixDAQ
 * One USB connector,
 * Two BNC connectors, and
 * A power adapter with an ON/OFF switch.



In order to capture the data, the SonixDAQ has to be connected to the Sonix ultrasound system. For this purpose, the SonixDAQ probe connector should be connected to the Sonix system's lowest probe slot. The other probe slot of the Sonix system is reserved for the actual probe that transmits and receives the ultrasound signal in a standard way.



The next step is to connect the DAQ BNC and USB connector to the correct Sonix systems's BNC. One BNC is used for synchronizing the data in the DAQ with the Sonix system (Note: The other BNC is not used at the moment). USB connector is also used both for programming the DAQ and transferring the data from DAQ to PC.

In the synchronous data acquisition mode, the DAQ waits for the sync signal. Thus, special care should be taken to ensure that the DAQ's correct BNC connector (input sync) is connected to the Sonix system's correct BNC connector (output sync). The following figures show the correct connectors for both the DAQ and the Sonix systems.



After this step, the SonixDAQ is ready to be powered up. Once powered up, three green LEDs beside the power button should turn on.

A high-level block diagram of the SonixDAQ is shown below. The orange circles show some of the parameters provided to the user for controlling the data acquisition. The details of these parameters are given in the SonixDAQ software.
