ADU-08e Quick Remarks ============================ GPS : Stationary and Moving Mode ---------------------------------- Stationary is the default for MT. The spatial resolution is *definitively* increased by averaging the position to to ± 2m. |br| Especially when you are beside a building where the view is strongly limited. Moving mode is for measuring many HF sites with the :ref:`SHFT-02e ` and the system is *not* rebooted when moving from site to site. |br| When measuring in open space the positioning is excellent; in situations as above the resolution decreases to ± 6 to 8m worst case. In terms of timing we couldn't measure any difference. .. image:: /media/adu-08e/moving_mode.jpg :width: 60% :align: center Power ------- Quickly pressing the power switches on or wakes the ADU. Long press when running opens the menu for shutdown. Connecting the Ethernet cable will **wake** the ADU within **32 seconds**. Otherwise: wake the system by pressing the power button. Ethernet / Samba --------------------- With the 10GB Ethernet (you "CAT 5e" or better ("CAT 6", "CAT 7") ) the ADU provides a download speed up to 100 MB/s. |br| If you have a wrong / bad cable you may get slow 300 kB/s. High Pass Filter ("HF HP 500Hz") ----------------------------------- This filter suppresses frequencies below 500 Hz and makes clearer AMT data. |br| By default this filter is disabled, because with 64kHz -> 16 kHz you easily get results for less than 500 Hz. .. index:: single: Radio Filter Radio Filter ("LF RF1", "LF RF2") ------------------------------------ RF2: for less than 1500 Ohm *contact resistance* (default) |br| RF1: for more than 1500 Ohm *contact resistance* |br| Use RF2 & DIV-1 for **buffer** cables! |br| Use RF1 & DIV-8 for **MFS-XXX** and **SHFT** coils The mobile App will detect the settings automatically. |br| The Joblist editor **not** (status 2018 May) |br| WebInferface: manual. |br| Chopper ----------- Chopper is ON for frequencies 512 Hz and lower. |br| Chopper is OFF for frequencies 1024 Hz higher. |br| Do not change it unless you know what you are doing. |br| HINT: when down filtering the atsheader (and XML) will keep the chopper settings for sure. In addition the header entry "orig_sample_freq" or binary OrigSampleFreq will keep the original sample frequency; that gives a hint later why chopper is off but file shows 128 Hz for example. Ref.: :ref:`ats header ` No Grounding - No Data ------------------------- There is **NO** chance to recover the data in this case. |br| Hence: if you use a small metal stick for grounding, make sure that the stick sits tight in the ground. Normally after hammering a few times the stick sits deep but *loose* in the ground. Site Configuration --------------------- As long as you do not press "new session" the site configuration is **persistent** in the WebInterface and the **mobile app**. As long you use the mobile app the should be no need to clear the data by "new session". you will only do this when you scrambled up the system. |br| If the site config in the mobile app is given, you will find this later as comments in your EDI files! |br| For the upcoming versions of ProcMT all Unicode characters should be allowed (Russian, Japanese, Chinese, German). .. meta:: :keywords: USB, copy, sdcard, network .. _adu-08e-quick-remarks_network_and_download: Network and Download ------------------------- Some laptops do not get the download speed as you want it. The cable interface should deliver a performance of 20 MB/s. That is the best. On WiFi you expect 3 MB/s. If all is **too slow** you have two options: |br| A ) default ^^^^^^^^^^^^^^ on the panel go to |br| **home->USB** |br| insert a USB drive (e.g. at the outside of the ADU is a second USB connector, so WiFi can stay ON). |br| **USB Device Connected!** |br| **CP-TS** |br| ... wait .. |br| **Eject** |br| (if you are not fast enough the drive will be re-mounted - but no problem *pull it*!) |br| Average speed is 12 MB/s writing to the USB pen drive. |br| Advantage: the USB pen drive can be read / write on all computers because they have FAT system. These USB drives are typical equal/less 32GB. If you have 64GB this may contain a different file system. B ) Linux / MAC users ^^^^^^^^^^^^^^^^^^^^^^^^^^ can use the SD card directly **home->status** |br| **jobs** |br| **EJ-SD** |br| copy the data with your card reader from the ext4 formatted SD card |br| **In-SD** Average speed is 140 MB/s copying to you laptop. C ) Windows 10, with ext2fsd ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ There is a *driver* called **Ext2Fsd** - Ext2 File System Driver for Windows 0.69 |br| (watch out that the version must be >= 0.69). Link is here for example `Ext2Fsd `_ This can be installed a executable on demand or as a *driver* - you want install as driver (reboot required). |br| The expected speed is 40 MB/s. **64 GB is NOT SUPPORTED, 32 GB is the maximum for this driver** That is also the maximum size of the internal card. **HINT** Take a simple card reader - and not a one who is "intelligent". Here Transcend TS-RDF5K (10 EUR). .. image:: /media/adu-08e/simple_transcend.jpg :width: 50% :align: center .. _external_usb: External USB ----------------- Most USB drives **do not work at all**. They are not made for field usage. |br| Much better are SSD drives; they are working reliable. Shown on the picture a self made with M2.SATA interface and a Samsung SSD inside .. image:: /media/adu-08e/ssd_adu_small.jpg :width: 60% :align: center please also take a look :ref:`here ` Short Comparison with ADU-07e ---------------------------------- The ADU-08e realizes all improvements we made with the former system and desired features. * less **power consumption** (down to 6.5 W in LF mode, instead of 9.5 W) * **GPS** with ten times higher sensitivty (works in steep valleys and under trees) * include **Galileo and Glonass / Beidou 北斗** for having always satellites in view * fully operational my **tablet and mobile phone** with the Android :ref:`App ` * **32 bit** ADC for LF mode - better performance especially when the E-field is drifting * optional **2 channel** :ref:`ADU ` for EMAP (no cable connection between center and satellite stations needed) * https server integrated for save operation across mobile and other networks * no battery drain when the system shuts down * 524 kHz sample rates always available ( LF + HF board are now integrated as BB board (broad band) ) In summary we tried to implement all user requests of the past years in order to make the ADU-08e the best system for you.
