Warnings, Cautions, and Important notices throughout this manual guide you to avoid injury, prevent equipment damage, and determine equipment use when varying components or configurations exist. Notes provide tips or additional information. SERCEL is not responsible for damages or injuries that result from failure to observe the information provided. WARNING When a Warning or Caution appears with a lightning-bolt icon, as shown in this example, this is to indicate a potential hazard that may lead to bodily injury or even death. CAUTION When a Warning or Caution appears with an exclamation-point icon, as shown in this example, this is to indicate possible equipment damage or potential risk of misuse and incorrect operation. IMPORTANT Important notices appear in the manual to highlight information that does not affect the risk of bodily injury, death, or equipment damage, but is nevertheless important. These notices appear with a stop-sign icon, as shown in this example.

It is a single channel autonomous field unit including a QuietSeis MEMS Sensor. It includes wireless communication capabilities to deliver its QC statuses and acquisition samples. DFU Functions Ground acceleration recording Filtering, compression and time stamping of the data Offloading of recorded data in the rack Local data storage transmission on request Instrument and sensor tests Selectable low cut filter down to 0.15Hz AFU - Analogue Field Unit The AFU is the WiNG system’s Analogue Field Unit (ref. 10042274). It is a single channel autonomous node including an external KCK2 connector for geophone. It includes communication capabilities to wirelessly deliver its QC status. AFU Functions 24 bit A/D conversion of the signal Filtering, compression and time stamping of the data Local data storage and re-transmission if needed Instrument and sensor tests Selectable low cut filter down to 0.15Hz Magnetic power stick (ref. 10045283) enabling to power ON & OFF the field units based on Hall effect. DFU Connector used to connect field units to the Rack* Connector used to connect field units to the Rack or to connect a geophone Spike LED Hall effect sensor AFU *Refer to “Harvesting & Charging the battery” chapter. Rev.1-2021 Page 6 High-sensitivity geophones Rev.1-2021 Page 7 Description of radio protocol Dual radio The MAC manage 2 independent radios with a separate data flow and different radio modulation (LORA and GFSK). Only one of them can be used without GNSS synchronization (this radio should be used for a troubleshoot radio). LORA is used to communicate between DFU through FHSS (Frequency Hopping spread Spectrum) technical and transmit state of health and settings. GFSK is used to communicate with an external equipment (WiNG Field Monitor box) through FHSS technical to send state-of-health data of several DFU, some of its own seismic data or receive settings. Time sharing with dual radio on 1 second. Frequency range and channel spacing The frequency range covered by the equipment is 2402.5MHz up to 2478.5MHz, using 1MHz channel spacing. According to FCC rules FHSS (Frequency Hopping Spread Spectrum) scheme is used, on 20 different frequencies. Data rate Data rate is 22.2Kbps with LORA modulation and 1Mbps with GFSK modulation. FHSS The FHSS operates on a set of frequencies. It uses one frequency for a fixed period of time and then switches to another channel. The next frequency is given by a pseudo-random sequence. In order to communicate, the transmitter…
