A customer reached out to support about inconsistent arrival times on stacks using his ES-3000. After stepping through the set up, he sent the .dat files for us to look into. it was mentioned that the seismograph itself is not capable of randomly triggering early and that there was something external to the instrument causing this 100-200mS early trigger event to occur. Another puzzling factor was that it occurred randomly after a number of shots in auto-stack mode (10). it took some investigating and convincing, but what was finally concluded that the sled ...

@rzhang Thank very much for the immediate response. Legend!. All workign again.

@benjamin-johnson i uploaded a new config file. Please try it again.

Hey there, ive been using this tool with no issues for a few weeks, but not get the "trial period expired" error. ive redownloaded the config file and placed it in the directory as suggested here but have had no success. is there a new licence for this?

Q. We are now often being asked to provide our 2D seismic profiles to be used in real world models. When the inversion is done it has distance along line and depth/elevation as the output. is there a way to add real world Northing/Easting coordinates into the data file so it can be more simply reference to the real world location the data was collected? A. Thank you very much for using SeisImager.So you want to add coordinate to 2D Vp or Vs cross sections.You can use GeoPlot to add the coordinates either lat-lon or UTM.GeoPlot can import cross sections from ...

@easswar Hello, Thank you for you answer, i think it will really help me sort out the communication. When you mention the softwares available for this sync, do you recommend any one in particular? Also, i have been trying another option which is to use the ethernet port to transfer the data to the Raspberry Pi 4 (to its ethernet port as well), but i don't seem to receive any signal of any kind. Do you know if that's also already been tested? Again, Thank you.Best<

Hey There is no hardware limitation to use UART4 or UART5 for your application. The previous post you read was talking about UART not being implemented in the example code and not specifically about UART5. The existing pipeline does assume a single consumer and you will run into race conditions if you only implement a mailbox_pend for your UART transmission. i would recommend that you either remove the TCP mailbox or create a new mailbox for UART. We have tried UART streaming before without issue. Transmitting the raw binary data will cause issues with ...

Hello, i saw in a previous post that the current firmware only supports MFAM streaming via Ethernet, and that UART5 isn't supported. i'm modifying the Dev Kit firmware to add TX output on UART4 instead, by adding a parallel Mailbox_post in spiTaskFxns.c to a new UART4 TX task/mailbox, at 460800 bps. Before going further, i wanted to ask: is there any hardware-level reason UART4 wouldn't work here, beyond it just not being implemented in the stock firmware? Does the existing SPI→Ethernet pipeline assume a single consumer, in a way that could cause timing ...

We will provide the example source code for MFAM Dev Kit 'as-is' for your reference and review. Please note that we do not provide any technical support, maintenance, debugging, or updates for this code. Click below to download: Attachment : Tiva_Interface_EK_Public.zip

if there are any practical examples of methods for acquiring underwater position information when towing a MagElement, please let me know. For example, if acoustic positioning using transponders is employed, could you explain how it is implemented?

1. Establish WIFI connection between your PC and the MagStation. 2. Open a web browser and type in . Attachment : image.png 3. Click "Delete project storage" or "Download survey data" to delete or down raw data from micro-SD card. We recommend deleting raw data files after 700 hours data collection. 4. The downloaded survey data is in .magdata format. To convert it to CSV, open Survey Manager and create a new MagStation project. inside the project, create a new survey. Select the survey name, click "Import Data" and then choose the .magdata f ...

Geometrics instruments, such as G-864, MagEx, MagArrow, MagStation et al, communicate with a mobile device via WIFI. But because the instrument WIFI has NO internet access, some Android device, after connecting to the instrument for a while, will automatically start searching for another WIFI access point. To prevent this from happening, when the No internet Access warning window pops up after first WiFi connection, choose "Tap for options". On the following window, check the “Don’t ask again for this network” box and press “Yes” .

i got it . it's worked now.

Nice work! Thanks for sharing!
