HIS/LIS/PACS times do not match—does the hospital need cabinet GNSS NTP?
Advantage
Hospitals deploy NTP first so HIS, LIS, and PACS share one timestamp: disagreeing lab, imaging, or pathology times affect diagnosis and liability. Monitors, connected-device events, OR records, and facilities/security need the same base. SY-1231 is an inspectable LAN NTP Stratum 1 in the weak-current cabinet. Infusion pumps and ventilators typically enter via a time-synchronized clinical gateway or nurse station; do not list every bedside device as an NTP client. This unit does not replace an MLPS assessment or hospital-accreditation verdict.
Primary: SY-1231 (hospital)
Fit Small and mid-size hospital weak-current rooms: HIS/LIS/PACS, monitors and OR records, facilities/security need an inspectable on-prem source.
Not for Internet-only office sync with no audit mandate; or treating this unit as an MLPS, accreditation, or metrology certificate. Must-have IRIG-B / OCXO → coming 4096.
Acceptance facts
- Most urgent: HIS, LIS, and PACS must share one timestamp. Disagreeing lab, imaging, or pathology times affect diagnosis and liability—the first reason hospitals deploy NTP. Point those hosts at cabinet SY-1231 on UDP 123.
- Monitors / vitals: ECG, ICU, and telemetry need one clock to overlay waveforms and trends; anesthesia and medication times need the same base. Central stations use NTP; most bedside modules take the host clock.
- Connected-device events (pumps, vents, anesthesia, dialysis alarms and setpoint changes) need accurate time for incident and nursing review. Most devices are not NTP clients—they enter via an already-synced clinical gateway or nurse station.
- OR: video, anesthesia, instrument logs, and device clocks should line up. NTP-capable recorders and NVRs point at the cabinet source; proprietary devices go through a gateway.
- Facilities / admin: access, attendance, fire, NVR, ward call, nurse intercom, EMR, pharmacy, and supplies share one inspectable clock. Security and clinical subnets can share one 1231 if UDP 123 reaches.
- Compliance: hospital informatics rules, accreditation, and MLPS often require a shared time base; EMR, orders, and nursing times are legal evidence. This unit is an inspectable cabinet source plus Web CSV archive—not an MLPS assessment, accreditation verdict, or metrology certificate.
- Shipping SY-1231: BeiDou+GPS, TCXO, single 10/100M, cap 60, design reply ≈1800 req/s (16 sources). No IRIG, no OCXO, no PTP. Do not apply 1PPS nanoseconds to HIS clients. Commission with the hospital 10-step note.

FAQ
- Can a hospital just use public NTP?
- Yes if egress is stable and there is no on-prem time-source mandate. If HIS/LIS/PACS must be auditable, UDP 123 is firewalled, or accreditation/MLPS writes a shared time base, deploy cabinet GNSS NTP (SY-1231).
- Are infusion pumps and ventilators NTP clients?
- Usually not. HIS, LIS, PACS, EMR servers, monitor central stations, NVRs, and nurse-station PCs act as NTP clients. Infusion pumps, ventilators, and some anesthesia or dialysis units enter via a vendor gateway or a time-synchronized nurse station. List actual interfaces in the RFQ; do not treat every bedside device as an NTP client.
- Is this an MLPS or hospital-accreditation certificate?
- No. The unit is an inspectable time source so reports, monitors, OR, and facilities can share a clock. MLPS assessments, hospital accreditation, and EMR grading are issued by those programs. Accept on client measurement and the hospital 10-step note—not a factory PASS lamp.
