1. About Software Development Kit This software development kit is designed for software engineers and programmers who would like to write their own program with LabVIEW to control PCIUT3100 series pulser/receiver and analog to digital converter board and PCIUT3100T tone burst pulser/receiver and analog to digital converter board. Before install this software development kit into your computer, you need to install the driver and the standard oscilloscope software that come with the board, and make sure that the board is working properly. Refer to PCIUT3100 board user’s guide for details. Follow the instructions on the SDK floppy disk to install the software into your hard disk drive. By default all the files will be installed in the following directory: C:\USUTsdk\PCIUTDLL\LabVIEW The files are listed below: PCIUTDLL.dll - 32-bit dynamic link library to control PCIUT3100 board PCIUTDLL.lib - Import library. Need to be in the same directory as PCIUTDLL.dll pciut.H - Header file which defines the function prototype and symbols. PCIUTLV.VI - Example program for LabVIEW PCIUT3100sdkLV.PDF- PDF version of this user’s guide. The installation program also installs the following driver programs in the appropriate directories: pci9050.sys to c:\windows\system32\ directory plxapi.dll to c:\windows\system\ directory pcisdk.inf to c:\windows\Inf\other\ directory More than one PCIUT3100 boards can be installed in a computer. The user can write a program to talk to any board in the computer. The following sections describe how to control the board via a dynamic link library.

2. Hardware Configurations

The picture above shows the board layout and connector locations of a PCIUT3100 pulser/receiver and A/D combo board. There are four connectors at the left end of the board. They are PULSE OUT, RECEIVE IN, EXTERNAL TRIGGER IN, and SYNC OUT (optional). The first two connectors can be connected to a transmit transducer and a receive transducer. If the pulse/echo method is used the RECEIVE IN connector can be left open. When more than one PCIUT3100 boards are used, one of the boards will be the master board, and the rest of them are slave boards. All the EXTERNAL TRIGGER IN connectors on the slave boards are connected to the SYNC OUT connector of the master board. In this case when the master board takes data all the slave boards will take data at the same time. The following sections provide some technical information about the connectors on the board. 2.1 J360 Quadrature Encoder Inputs and Digital I/O Pins J360 is a 26-pin header connector. It consists of encoder inputs, 8 digital inputs and 8 digital outputs. A ribbon cable with a 26-pin header connector and a DB25 female connector is provided with the encoder option. The following picture shows the pin location and the connections. 1 2

3. Dynamic Link Library A dynamic link library PCIUTDLL.dll is provided with this software development kit to give a user an access to PCIUT3100 pulser/receiver and analog to digital converter board from a LabVIEW program. There is only one function call in the dynamic link library PCIUTParms() to send the parameters to the board and get acquired data as well as encoder information from the board. There are four parameters for the function call PCIUTParms(). int PCIUTParms(int mode, int board, DWORD wParam, int lParam); Parameter mode is a number starting from 1000 that defines the purpose of the function call. Different number specifies different control tasks. The values of this parameter are defined in the pciut.h file. See Appendix A PCIUT.H Header File for details. Parameter board is the board number. A 0 specifies the first PCIUT3100 board in the computer. If an invalid board number is specified, the parameter will be downloaded to the active board. A function call with a valid board number will set the active board. Parameters wParam and lParam are the additional information past to the function. They have different meanings depending on the parameter mode. Also see section Working with LabVIEW for more information. The function returns –4 if no board is detected in the computer. 3.1 ISDATAREADY (mode = 1000), Get data status Get the status of the data acquisition process. wParam: not used lParam: not used. Return: 0 if no data in the memory yet. Otherwise there are data in the memory. 3.2 SOFTWARETRIGGER (mode = 1001), Generate a software trigger Generate a software trigger. After this function call the board will generate a pulse from the PULSE OUT connector, and the analog to digital converter will start converting analog signal to digital data with the user-specified parameters. The digital data will be saved in the -board memory. To generate a software trigger, the trigger source needs to be set to software trigger. See the section mode=1016 below for details. wParam: not used lParam: not used. Return: 1 if successful. 3.3 SETSAMPLINGRATE (mode = 1002), Set Sampling Rate Set sampling rate. wParam: index which is from 0 to 7. Default is 0. The following list shows the settings for

10

wParam: index which is 0 or 1. Default is 0 which is pulse/echo. 0 – pulse/echo. In this case the board connects PULSE OUT and RECEIVE IN together.

1 – through transmission lParam: Not used Return: 1 3.10 SETBUFFERLENGTH (mode = 1009), Set Buffer Length Set the buffer length that specifies how many data samples that the next acquisition will collect data. wParam: number of samples to take. It ranges from 16 to 16382 in step of 4 samples. Default

value of the buffer length is 4000 samples. lParam: Not used

Return: 1 3.11 SETTRIGGERDELAY (mode = 1010), Set Trigger Delay Set the trigger delay that specifies how many samples that the next acquisition will skip before collecting data.

wParam: number of samples to skip. It ranges from 2 to 32764 samples in step of 2 samples. Default value of the trigger delay is 2 samples.

255 which is -40V. Section 3.35 describes how to get the information about the –350V pulse voltage.

Pulse voltage can be set from -40 V to -300 V. The formula is pulse voltage (V) = -(4 + 4000 / (0.392157 x Index + 13.5)) Use the following formula to calculate the pulse voltage for –350V option pulse voltage (V) = -(4 + 4000 / (0.392157 x Index + 11.56)) lParam: Not used Return: 1 3.13 SETPULSEWIDTH (mode = 1012), Set Pulse Width Set pulse width for the standard pulser or the number of half cycles for the tone burst pulser PCIUT3100T. wParam: For standard pulser the index from 0 to 255. Default is 0 which is the minimum pulse width. The minimum pulse width Wmin can be obtained by using function call mode=1025. Normally it is 50 ns or 15 ns with special order.

Pulse width can be set from minimum pulse width to 480 ns. The formula is


11

Pulse width (nanoseconds) = Wmin + (760.8 x index) / (161.67 + Index) If the result is less than Wmin, Wmin should be used.

For tone burst pulser the index is from 1 to 32 which is the number of half cycles. See the section SETTONEBURSTFREQUENCY to set the frequency.

lParam: Not used Return: 1 3.14 SETGAIN (mode = 1013), Set Gain Set the receiver gain. This function sets the gain of both fixed gain amplifier and the DAC amplifier. If DAC is on, this function sets the fixed amplifier only. The DAC gain can be set by using function call mode=1015. When the gain is a negative number, the amplifier acts like an attenuator. At this point the attenuation is not linear to the calculated value. So the attenuation value is not reflecting the true attenuation. The number is just for reference. wParam: index which is from 0 to 1023. It specifies the total gain from -20 dB to 80 dB for both

amplifiers, or -10 dB to 40 dB for the fixed gain amplifier along. Default is 511 which is 30 dB of the global gain. Receiver gain can be set from -20 dB to 80 dB with about 0.1 dB resolution. The formula is

Receiver gain (dB) = 0.0978 x (Index – 204) lParam: Not used Return: 1 3.15 SETDCOFFSET (mode = 1014), Set DC Offset Set the receiver DC offset. wParam: index which is from 0 to 1023. Default is 511 which is 0V. DC offset can be set from –2.5V to 2.5V with 5mV resolution. The formula is DC offset = 0.005 x Index lParam: Not used Return: 1 3.16 SETDACTABLE (mode = 1015), Set DAC table Set the gain table of the distance amplitude correction (DAC). When the DAC is on, the gain value on the table will be used to set up the DAC amplifier while taking data. Starting from the first element on the table the board hardware will change the gain every 16 samples until the end of the data acquisition. When the DAC is on, the maximum gain of the fixed gain amplifier is 40 dB and the maximum gain of the DAC amplifier is also 40 dB. Each element of the table is an unsigned one-byte number that is from 0 to 255 for gain range from -10 dB to 40 dB. wParam: pointer of the table: (unsigned char *)

The element value can be calculated with the following formula:


12

Element value = 5.1 x G + 51 where G is the gain from -10 to 40, and the element value should be from 0 to 255. lParam: number of elements in the table. The number of the table element should last long

enough to cover the data acquisition time which is buffer length / 16. Return: -2 if wParam is NULL or 1 if successful. 3.17 SETADTRIGGERSOURCE (mode = 1016), Set A/D Trigger Source Set the trigger source of the analog to digital converter. WParam: index of the settings. Default is 1. 0 – +External trigger. The board will take data when a transit of 0 to 5V (rising edge) signal

appears at the EXT TRIG connector 1 - Software trigger. Use mode=1001 to generate a trigger. 2 – -External trigger. The board will take data when a transit of 5 to 0V (falling edge) signal

appears at the EXT TRIG connector lParam: Not used Return: 1 3.18 GETENCODERCOUNTER (mode = 1017), Get Encoder Counter Get the encoder counter from one of the counters. wParam: index of the counter.

18

lParam: Not used. Return: The minimum voltage. 3.46 GETVMAX (mode=1045), Get Maximum Voltage This mode is used to get the maximum voltage of the pulser. wParam: Not used. lParam: Not used. Return: The maximum voltage. 3.47 SETTONEBURSTFREQUENCY (MODE=1046), Set Tone Burst Frequency This mode is used to set the frequency of the tone burst pulse. The tone burst pulser generates a periodical square wave instead of a single pulse from a standard pulser. It applies more energy to a transducer especially a low frequency transducer. The frequency of the burst pulses should be the same as the frequency of the transducer in order to get the maximum energy. The pulse voltage defined in section 3.11 will be the peak to peak voltage. So 300V means +/-150V. The starting polarity and pulse cycles (see section 3.12) are also programmable. The following picture shows some examples of the tone burst pulse. Example 1: Polarity: positive Half cycles: 5 Voltage: 300V Frequency: 40 kHz Example 2: Polarity: negative Half cycles: 4 Voltage: 150V Frequency: 80 kHz Here are the parameters for this mode: wParam: Frequency in kHz from 20 to 10,000. lParam: Polarity: 0 = Positive, 1 = Negative
