One Answer.\u003c\/h2\u003e\n\u003cp\u003eThe central recorder that brings every instrument in a structure onto one synchronised timeline, from two sensors to a full array of sixteen.\u003c\/p\u003e\n\u003ch3\u003eSummary\u003c\/h3\u003e\n\u003cp\u003eEQR-C is a multi-channel seismic data acquisition system that synchronises anything from two instruments up to sixteen, including accelerographs, LVDTs, and weather stations, into a single dataset with microsecond-level GNSS and PTP timing. Designed as the central recorder for the EQResponder structural monitoring ecosystem, it is built for everything from a couple of instruments at one structure to full multi-instrument deployments across buildings, bridges, tunnels, dams, and other critical infrastructure.\u003c\/p\u003e\n\u003ch3\u003eDescription\u003c\/h3\u003e\n\u003cp\u003eStructural arrays fail to deliver useful data not because the sensors are wrong, but because the data from different instrument classes never lines up in time. An accelerograph trigger that is 50 ms out of sync with an LVDT reading is next to useless for diagnosing what actually happened during an event. EQR-C synchronises, aggregates, and centrally manages every sensor in a deployment. Accelerographs, displacement sensors, and environmental stations are coordinated to microsecond precision, and output as a single coherent file.\u003c\/p\u003e\n\u003cp\u003eSingle-purpose recorders force you to reconcile timestamps across separate logging systems after the fact. EQR-C does the synchronisation at the point of acquisition. You get one MiniSEED or CSV file, correctly time-aligned, in standard formats with no proprietary software to license, ready for analysis. No reconciliation exercise required, and even two instruments become one coherent record instead of two files to line up by hand.\u003c\/p\u003e\n\u003ch3\u003eWho it's for\u003c\/h3\u003e\n\u003cp\u003eEngineers and asset owners running anything from a couple of instruments at a single structure to full arrays across buildings, bridges, tunnels, dams, and other critical infrastructure, who need more than one instrument, and sometimes more than one class of sensor, to tell a coherent story about how a structure responded to an event.\u003c\/p\u003e\n\u003ch3\u003eWhat it does\u003c\/h3\u003e\n\u003cp\u003eEQR-C coordinates up to 16 connected instruments, accelerographs, displacement sensors, or environmental stations, into one array. Each sensor is individually configurable, centrally controlled, and fully time-synchronised. It can run as a PTP master, driving timing for the rest of the array, or as a PTP\/GNSS slave, synchronising to an existing time source. This gives you flexibility in how the array's timing hierarchy is built.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eFull Technical Specification\u003c\/h2\u003e\n\u003ch3\u003ePhysical\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 140 x 84 x 50 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 0.8 kg\u003c\/li\u003e\n\u003cli\u003eHousing: Aluminium case, IP54 standard, IP65 enclosure option\u003c\/li\u003e\n\u003cli\u003eMounting: Separate mounting plate with protective dust cover\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePower\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInput range: 10.5 to 30.0 V DC\u003c\/li\u003e\n\u003cli\u003eTypical consumption: 2.0 W at 13.8 V input\u003c\/li\u003e\n\u003cli\u003eBackup: 12 V SLA, 7.0 Ah, 36-hour runtime. 230 VAC to 13.8 VDC plug-pack charger. 24 V SLA compatible (option)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommunication\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated LAN, external 3\/4\/5G cellular modem, Wi-Fi via USB or Ethernet\u003c\/li\u003e\n\u003cli\u003eProtocol: TCP-IP\u003c\/li\u003e\n\u003cli\u003eServices: TLS-encrypted HTTPS web server, programmatic HTTPS API, email outputs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSensor Compatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNative: EQResponder Accelerographs (EQR-90, EQR-120), EQResponder LVDT, EQResponder Digitiser, EQResponder Weather Station\u003c\/li\u003e\n\u003cli\u003eOption: Class A accelerometer integration\u003c\/li\u003e\n\u003cli\u003eChannel capacity: up to 16 connected instruments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTriggering\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eArray-wide recording triggers from accelerograph, LVDT, or wind sensor inputs\u003c\/li\u003e\n\u003cli\u003eSimple or weighted trigger voting logic across the array\u003c\/li\u003e\n\u003cli\u003eAccelerometer triggers configurable by PGA or individual channel threshold\u003c\/li\u003e\n\u003cli\u003ePre-event window: 10 to 60 seconds.
