Solutions
Hospital, cabinet, security, auxiliary I/O (1PPS · PULSE · Modbus) → SY-1231; edge stamp+OCXO+IRIG → SY-4096; plant multi-port / dual supply → SY-8640. ★ marks focus industries.
HIS, EMR, and security subnets need one LAN time base to keep logs aligned. SY-1231 delivers GNSS-disciplined NTP Stratum 1 with BeiDou+GPS and TCXO holdover on a single port sized for typical weak-current cabinets—datasheet capacity and protocol boundaries support clear acceptance.
Primary: SY-1231 (hospital)
Learn moreProduction and automation cabinets need an inspectable on-prem time source for PLCs, IPCs, and logs. Single-port LAN NTP with one AC or DC inlet and front-panel LOCK checks; plan capacity from the datasheet formula.
Primary: SY-1231
Learn moreCameras, NVRs, and access platforms need consistent timestamps for correlation and search. Cabinet GNSS NTP keeps the reference inside your control boundary and cuts drift—usually a single LAN port is enough without hardware-stamp or OCXO upgrades.
Primary: SY-1231
Learn moreBeyond Ethernet NTP, sites often need TTL 1PPS, a minute PULSE, or RS-485 Modbus absolute time. Accept per channel—do not apply internal ns / 1PPS to NIC NTP. Shipping SY-1231 covers 1PPS + PULSE + Modbus (no IRIG); IRIG-B → SY-4096; multi-port / dual-supply → SY-8640.

Learn moreQuality & commissioning
Specs are written per channel. Each shipping unit passes a factory gate. Commission on-site with the datasheet, Web exports, and client checklist. Contract acceptance is client measurement—not a factory PASS lamp.
Each SY-1231 is gated before ship: LOCK, LAN NTP, and 1PPS / PULSE / Modbus checked per channel. The Web UI shows a read-only factory record (PASS/FAIL); the ship ticket records SETID and firmware Build. Fixture thresholds stay internal; a PASS sheet without process detail can ship with the unit when required.
The datasheet and interface annex give per-channel steps: scope the 1PPS jack and Pin4 minute pulse, NTP via the client checklist, Modbus via the register map. The LCD is for patrol; accuracy and events go out as event_log.csv and quality_24h.csv. Hospital sites also have a 10-step bring-up note.
Support needs SETID, firmware Build, and event_log.csv / quality_24h.csv. The Sync Assistant is an optional field health-check (SNTP / client status)—not a metrology certificate, and it does not change host time by default. The config command library is licensed. The factory gate EXE is production-only and not a public download.
QA wording: include/exclude and accuracy layers follow the shipping datasheet. For support, send SETID + Build plus event/quality CSVs. Do not put internal second-edge figures into NIC acceptance.
