DacqMan + RS104 (IS-Target / Low Energy)

Here’s the quick start guide on how to acquire data with DacqMan running the RS104 (IS-Target, Low Energy) UT Scanner. This guide here includes just the basic steps. Really, just a few clicks to start your scan runs.

NOTE: You may use a customized version of DacqMan. Data formats, sequence of operations, what the screen looks like – all of those might be different. A version of DacqMan that is running on your computer might not include the customizations that you need.


Quick Summary

FOLLOW YOUR SAFETY PROTOCOL AND THEN WHEN READY:

  1. Start DacqMan
  2. CONNECT to the ports
  3. Select your data output directory
  4. START the data stream
  5. Adjust transmit/receive gains and maybe receive delay
  6. STOP when you’re done

Quick Troubleshooting

If the waveforms stop their one-second yellow flashes and file progress stops, try STOP and then START again (these early versions of DacqMan might sticklers about bit errors)

STOP and Reload DacqMan

Click the red bar at the top “(click to reload this App)” or use Ctrl-R (Windows/Linux) or Cmd-R (Mac) to Reload Dacqman

Close DacqMan and re-start it


The steps in a little more detail:

Step 1: Before You Start: Make sure to follow your safety sequence protocol first!


Step 2: Things That Are Already Set Up

  • hardware and PC setup are already done and tested prior to deployment
  • version of DacqMan (customized or stock) installed on the PC works for your situation
  • After your safety protocol, the hardware is now deployed, powered up, and the USB adapter is plugged into your PC

Step 3: Double-Click the Desktop Shortcut or “DacqMan.exe” in the correct directory to start DacqMan


Step 4: Click “CONNECT TO PORTS AND BEGIN LISTENING FOR DATA”

Figure 4.1: If everything is set up, on starting DacqMan, the screen will look like the above image (as of October 2021). Note that (box, right) UseForData and UseForControl are auto-selected. And note that above the “CONNECT TO PORTS AND BEGIN LISTENING FOR DATA” there is an indicator that “HARDWARE IS: HDL-0104-RS104 (RS104)”.
Figure 4.2: After clicking “CONNECT TO PORTS AND BEGIN LISTENING FOR DATA”, the ports section collapses and screen looks like the image above. The “Click to select the output directory” bar strobes green to tell you that this is the next step. That is, to select the directory where your data files will get auto-saved.

Step 5: “Click to select the output directory” + “Start Capture to this Directory”

Click anywhere in the area (shown in Figure 4.2 above) near the folder icon to select the directory where the files from the streaming data will be auto-saved.

Use a directory location per your organization’s naming conventions.

Don’t use an active cloud-based location, unless you’ve tested this before.

Click “Start Capture to this Directory” when you’ve created or selected the right location.

After selecting your directory, the full path to this directory should show up next to that directory icon in the DacqMan window where you clicked to set the directory.

Figure 5.1: “Click to select the output directory” opens the dialog windows to pick your directory where data will be auto-saved. Use a convention that makes sense. When you’re ready, click “Start Capture to this Directory”. All of the scan files will be saved here, with sequence numbers added to their file names automatically.
Figure 5.2: Click “Start Capture to this Directory” to complete selecting the data output directory.

Step 6: (Optional) Enter “Structure ID Information”

Figure 6.1: Optionally, click the “Structure ID Information” field to enter structure information. Legacy file format compatibility requires that this field is limited to 64 characters, and non-letter/number characters might confuse the system, so make sure that is known and keep it simple.
Figure 6.2: Structure information added, as an example.

Step 7: “START” [Big Green Button] (or maybe Step 8 is first for you)

This is to your taste and protocol. I like to click START first so that when I change Transmit (Tx) voltage (gain) and Receive (Rx) gain and delay (if necessary), I can see the changes in the waveforms real time.

But, maybe, your preference or required protocol says that you set those first (see Step 8), and then click “START”.

Look at progress indicators and graph updates (see caption for Figure 7.1).

Figure 7.1: After you click START, the waveform view section expands to show 4 waveform graphs (here, in the screenshot, only 2 are shown). The graphs flash light yellow when they have been updated. The data streams to file very fast. The graph updates are typically slower. STOP is enabled. The file progress is shown right above the disabled START button. NOTE here the waveforms are flat because we haven’t yet turned up any Tx or Rx gains! You might set the gains and delay first and then START. Up to you or your protocol.

Step 8: Adjust Gains and Delay (or do this first and then Step 7: START)

Click “CONTROL PORT >” [GREEN] to expand (or later collapse) the Tx/Rx control sliders section.

Figure 8.1: Click “CONTROL PORT >” to expand the Tx/Rx Controls section

Scroll down to the Control Sliders Section, just above the waveform graphs. Use the sliders to adjust the settings. USE ONLY the right hand side “Set Tx Voltage” and “Set Rx Gain” and maybe if you need it the “Set Rx Delay” at the bottom left of the slider section.

Click the green circle of the slider, move it where you want, watch the number the pops up above the circle when you slide. The new value is sent to the RS104 when you release the mouse button after sliding.

When you’re done, you can collapse the CONTROL PORT section again if you want to so you just see the file progress and waveforms. Just scroll to the top and click “CONTROL PORT” again to collapse that section.

Typical values seem to be as below these days – BUT – watch your waveforms too for what you need, or use your standard protocol:

  • Set Tx Voltage: around 6 or 8? Higher is generally fine. Check with the pre-deployment testers or supervisors. This values is different compared with the DLITE-0100A1 series and can be set much higher.
  • Set Rx Gain: around 4 – 8?
  • Set Rx Delay: there are only 4 positions on this slider, separated by a lot on the scale, so you might leave it at default (0, all the way to the left) or set it to 1 – watch your waveforms. This relates to the distance of the transducer face from the target surface you are scanning.
Figure 8.2: In the expanded Control Port section, scroll down to see the Tx/Rx sliders. Only use the Tx Voltage, Rx Gain, and Rx Delay (if necessary) sliders. The setting takes effect when you release the mouse button after sliding.
Figure 8.3: Here the Tx Voltage and Rx Gain adjustments have been made during scanning (after clicking START). Also in this version of DacqMan, listening with headphones, the user can hear the change in the waveform as the Tx voltage is turned up. This setup is not immersion – it is bench, so your results will vary.
Figure 8.4 After your gains and delay are adjusted, you may want to collapse the control sliders and buttons area (just click CONTROL PORT again) and enjoy watching (and listening to) the received waveforms while watching file progress. You can watch for file progress and the waveforms to flash with updates. If progress stops, see troubleshooting at the top of this guide, or click STOP and then START again, etc. DacqMan right now, in early stages, may be a stickler for bit errors. Your customized version of DacqMan may include analysis numbers displayed on the waveform graphs as well.

Step 9: When finished, click STOP. If you’re completely done with all the scans needed, just X out of DacqMan to quit the program.
