Is there an api/script for quickly converting the dbt files to csv without using the Survey Manager? For example, if we do 30 surveys on a day, I would like to run a Python script that exports this 30 dbt files as 30 csv files automatically, without having to do it 30 times on Survey Manager.

If you have multiple MFAM Dev Kits and wish to assign different SSIDs, you can download the following program to generate a customized SSID. The instruction is also included. Attachment : Dev Kit WIFI.zip

@rzhang Thank you for sending the file. By the Way, is there a Way to convert the data from binary to text format? Additionally, is the data output from the MagElement in binary format?

Hello Dear Rui, I have questions regarding MagArrow Magnetic data compensation, if you can answer please, 1- Does the heading error compensation that applied by surveying data processing program remove the heading effect due to direction only or calibrates the maneuver effect due to the swinging of the sensor as well? 2- Regarding the heading compensation flight, I am confused about the best Way to do this. In the manual, it is mentioned that we can apply a cloverleaf pattern (this is usually used in airborne survey) or a survey pattern or we can do a 360 degree turn at a certain point. However, it is written that we can use the calibration data measured in the turn, can I use the data from the turn to apply the heading error correction separately for each flight instead of doing a heading flight. Regarding the cloverleaf pattern application, is the data also processed in the same Way using surveying data processing program? 3-What is the importance of the base station magnetometer data in this correction as mentioned in the manual, I think we can apply it without base magnetometer? 4- Finally, is there a specific flight that can be done to make maneuver correction (FOM) (roll, pitch and yaw) that we apply in conventional magnetic airborne survey? or We just resort to the LP filter. Sorry for the long post Kind Regards, Ahmed

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 sledgehammer in use had some "flex" in the handle that would cause a "pre-trigger" on the downswing. Once the hammer was replaced the pre-triggers ceased.   Thanks again for the time on the phone today. I really appreciate the guidance and experience of your team.   After the discussion with your team, this led me to do a few more tests on the equipment. This evening, I got 40 stacks with no inconsistency in arrival times.   To close the loop on what I think was going on: I believe the hammer itself may have been the issue, husky hammers have a shock absorber and a sloped handle. Having the trigger strapped in a particular Way on the hammer may have been the cause here. See image below:   Attachment : Husky Hammer.png   I used a new hammer (NOT HUSKY) and did not experience the inconsistent arrival times. I will continue to monitor the issue. I appreciate the support from your team! I've individually swapped out all other components (aside from the geode) - this is the only change that seems to have solved the issue.   In summary: My theory is either the shock absorber, or sloped handle caused the trigger to delay, resulting in early arrival times.

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 PlotRefa (.vs) and WaveEq (.pvs).Use "Edit", "XY coordinates (latitude-longitude)" to add the coordinates.See GeoPlot manual for more details. If you have several cross-sections, you may use GeoPlot3D to interpolate 2D cross sections to a 3D volume.

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 issues if I add a second parallel mailbox post for UART4? Has anyone tried UART-based streaming from the Dev Kit before, and if so, any known pitfalls? Thanks in advance!

@rzhang Thank you for sending the sample data in ASCII format. By the Way, since the output data is in binary format, what functionalities are implemented on the AUV and ASVs side for the connection? Are you using Windows OS on the AUV and ASVs, along with "MagView MagElement" or "MagElementLogger"?

Verify BAUD Rate selected on dip switches 6,7,8 Note: according to a customer this is how the switches are set as they are attempting a file transfer at 115200 BAUD. Connect the G-857 to the computer using the download cable and a properly installed USB/RS-232 adaptor. (Must have FTDI): Open the MagMap Software. Select Import>G-857/ASCII 1. Enter known Serial Port (My computer is COM4) 2. BAUD 115200 (Switches 6, 7 and 8 off) 3. Set a good location for the file to written to. 4. Leave Download only, open later unchecked. 5. Leave download time out 2. Select OK. On the G-857 press OUTPUT, ENTER when this window opens. BYTES DOWNLOADED will begin to increment. Select OK in the window below: The downloaded Mag file should be displayed: If the download sequence does not happen this Way, it is usually a problem with: 1. USB/RS-232 Adaptor not FTDI, or driver not installed. 2. COM PORT assignment incorrect, and/or file destination not valid. 3. BAUD RATE mismatch. 4. Faulty I/O Cable PN 16492-01. 5. Faulty Computer. 6. Faulty G-857 console. Check to make sure that the G-857 is not in Legacy Mode: To check if Legacy Mode is enabled press: AUTO-OUTPUT To turn it off press: AUTO-OUTPUT-CLEAR To Turn on: AUTO-OUTPUT-ENTER If Legacy Mode was on then the recorded data recorded needs to be downloaded as a G-856:

What Affects Geode Trigger Cycle Times? If you're trying to optimize your Geode system for faster trigger cycles—especially in high-repeat environments—there are a few key factors to consider. The goal is to ensure that the system completes its entire cycle (trigger → recording → data transfer → re-arming) before the next expected trigger. Here’s what influences that cycle: 🧠 Core Factors That Affect Cycle Times 1. File Size (Sampling Parameters) Your sample interval and record length directly affect the size of each data file.You can view the resulting file size in the Acquisition Parameters menu.Larger files take longer to transfer, which delays the re-arm process. 2. Data Transfer Rate The Geode typically transfers data at around 450–465 kb/sec.Reducing file size is the best Way to reduce transfer time and speed up the cycle. 3. Calibration Frequency By default, the system may attempt to calibrate every N shots, which takes additional time.Go to Options > Calibration and set "calibrate every N shots" to a large number (e.g., 100000) to prevent unnecessary delays. 4. Recording Delay and Record Length If you're operating in a region with a consistently deep seafloor, you can add a recording delay and reduce record length accordingly.Example: If the water column is always >0.3s, you can apply a delay of 0.2s and reduce record length by the same amount.This trims your file size and speeds up the transfer/re-arm process. ⚙️ Best Practices Use the Auto-Trigger function or set trigger sensitivity to the maximum value for testing.Monitor the cycle timing and adjust acquisition parameters to stay within your trigger window.It's often an iterative process to find the ideal configuration for your environment.

Hello, guys.I need to ask some questions about grounding technique for Geode seismographs. Current territory that we need to investigate has strong electromagnetic pollution from nearbuy high voltage power line. When using 48 to 96 geophones many channels experiencing strong EMI interference in wide spectrum. So I want to ask the forum society for some advices on the grounding technique of Geode modules. Because in documentation there is only a mention of "grounding plug" on the side of boxes. But there is no advices on how to properly ground 4 or more modules, distanced 240 meters from one another. Even more when soil has different properties along streamer line (moisture etc). On geometrics.com could not find any instructions on rightful grounding technique. Maybe there is exist some sort of special grounding schemes for large number of modules in use. As I understand the better Way is to have star topology for grounding (with one common rode point for several devices) when using spreaded device system. Because in other cases ground potential for different modules will vary. Maybe I asking a silly quastion but EMI problem anyway exist on long receivers arrays. That ruins noise/signal ratio and etc. Thanks.

@ahmed_ramadan_geo Regarding your questions: 1. It removes the maneuver effect due to the swing of the sensor as well. 2. There are really NO best Way to do the compensation flight. There are two main requirements for a compensation flight: 1. Include as much roll/pitch/yaw motions as possible. 2. Avoid magnetic gradient. If you can fly the drone very high (>100m) over a low gradient area, a cloverleaf pattern is probably the best (as in traditional airborne surveys in which you can fly high to avoid the local gradient.). But this pattern is hard to fly, especially over a small area. 360-degree turn is simple and almost guaranteed to have no magnetic gradient in the compensation data since it is over the same location. If the MagArrow doesn't have much pitch and roll motion, 360-deg turn is sufficient. But it doesn't compensate well for pitch and roll maneuver noise (no much pitch/roll calibration). A survey pattern is between the two patterns described above. You may be able to use it, instead of doing a calibration flight. You can use the calibration file generation module to process the cloverleaf pattern. 3. Since the calibration flight is typically short, a base-station may not be necessary. Diurnal field change is usually not significant in a minute. 4. As I mentioned in 1., maneuver correction is also applied here. You can also use LP filter but make sure NOT to apply the heading compensation after the LP filter.

Hi guys, I need MFAM live data streaming from ethernet or serial UART5 for my project. Initially, I am planning to write a piece of code using C++ that reads the data from one of the ports and prints it on the terminal. To be sure that data is present on UART5, I connected this port to the USB port of my laptop using a suitable cable and tried to monitor data using Putty with different baud rates but found nothing. Is data streaming available on UART5 by default? or do I need to enable it? I can see data on the ethernet port using MagView. Ethernet port uses TCP protocol. Is there any Way to enable UDP on the ethernet port? In case I write code to read the ethernet port using TCP then please suggest a suitable reference to start. Thanks a lot
