TemporaSync SY-4096
Typical order model: SY-4096-GN-O-S
Half-width 1U · single-port Web ops. Hardware-stamped NTP, OCXO, 1PPS / IRIG-B DCLS / programmable pulse / Modbus. NTP Support: Up to 21,000 req/s (sustained 20,000–21,000); Accuracy ≤ 100 µs.
Fit Factory, campus, and building-edge cabinets that need stamped NTP, OCXO, and hardware time I/O on one subnet.
Not for Cabinet TCXO / lower cost → SY-1231. Multi-port or dual supply → SY-8640.
Adds on-chip IEEE 1588 hardware-timestamped NTP, OCXO, IRIG, and Modbus versus SY-1231; still one Ethernet port. Ethernet stamps and rear time I/O are separate paths. Up to 21,000 NTP requests per second (sustained 20,000–21,000); Accuracy ≤ 100 µs (network NTP, ≠ 1PPS). Planning N=⌊η×R/f_poll⌋.
How it differs from the other model
SY-1231 cabinet stock · SY-4096 half-width stamp + time I/O · SY-8640 multi-port / dual supply.

| Industrial bus | Modbus RTU slave, 9600 8N1, unit 1, FC 03/04 read-only |
| Constellation | Multi-constellation GNSS |
| Ethernet | 1× RJ45, 10/100M; timing and Web ops on the same port |
| Oscillator | OCXO |
| Power | AC 220 V (default) or 12–24 V DC; choose one |
| Availability | Available to order |
| Performance | Up to 21,000 NTP requests per second · sustained 20,000–21,000 · LOCKED, lab full load 24 h |
| Accuracy (network NTP) | ≤ 100 µs · lab sub-millisecond class · LOCK, direct or one switch; ≠ 1PPS |
| Planning | N = ⌊η × R / f_poll⌋ |
| Management | On-box Web ops: status, network setup, and record export; login required to change settings |
