TempoSync-3500
Typical order model: TempoSync-3500-GN-O-S Coming soon
Half-width 1U industrial NTP: IEEE 1588 hardware timestamps, OCXO holdover, and standard hardware time outputs (1PPS / IRIG-B / programmable pulse). LAN Stratum 1 for factory, campus, and building-edge cabinets.
Fit Factory/campus edge cabinets, building BA / rack-ready weak-current rooms, industrial I/O cabinets, production & security subnets—single-subnet stamp+OCXO+hardware time I/O.
Not for Immediate cabinet stock delivery (use TempoSync-3000); or multi-port / dual-supply plant flagship (see TempoSync-4000).
vs 3000: half-width 1U · hardware-stamped NTP · OCXO · hardware time I/O as standard; client ID cap ~200. Still single-port for edge stamp, holdover, and industrial time outputs—does not replace the 4000 multi-port / dual-supply flagship. Pre-gate reply rate per V-N10; aligned with datasheet v1.1 / website copy.
How it differs from the other model
Line-up: 3000 cabinet → 3500 half-width 1U stamp+OCXO+hardware time I/O → 4000 multi-port / dual supply. This page does not publish cross-model comparison tables.

Specification summary
| Form factor | Half-width 1U, rack-mountable |
|---|---|
| Timing protocol | NTP v3/v4 (UDP 123); IEEE 1588 hardware timestamping |
| Time reference | GNSS 1PPS + OCXO discipline |
| Hardware time outputs | 1PPS (BNC), IRIG-B DCLS, programmable pulse (PPM / cyclic); edge-aligned to the disciplined second |
| Constellation (order code GN) | Multi-constellation GNSS (module-dependent); BN optional (BeiDou-primary) |
| Ethernet | 1× RJ45, 10/100M (NTP and Web on the same port) |
| Oscillator / power | O=OCXO; S=single wide-range DC (see nameplate) |
| Identity cap | Default ~200 clients (policy/selection cap; ≠ guaranteed field density) |
| NTP performance | Sustained reply rate per V-N10 / validation report; do not publish unmeasured req/s |
| Management | Web; SNMP read-only per shipping firmware |
Interfaces
- GNSS ANT
- LAN · 1× RJ45 (NTP + Web)
- 1PPS · BNC
- IRIG-B · DCLS
- 485 + PULSE (pin 4 = programmable pulse, not 1PPS)
- DC · single wide-range
- Front status LEDs; optional display (-H)
Included
- GNSS-disciplined NTP Stratum 1 after lock
- IEEE 1588 hardware-timestamped NTP (on-chip TSU)
- OCXO holdover
- Hardware time outputs: 1PPS / IRIG-B / programmable pulse
- Half-width 1U · single-port Web ops
Not included (do not assume for tenders)
- Multi-port / dual-NIC failover / dual PSU as standard
- Using 3500 as a 4000 multi-port flagship substitute
- Invented throughput or “millions of clients” before V-N10
- Describing programmable pulse as a multi-OUT matrix; ns-level network NTP promises
Aligned with datasheet / website copy v1.1 (half-width 1U · hardware-stamped NTP · OCXO · hardware time I/O as standard). Design reply / sustainable R follow V-N10—do not put unmeasured req/s in contracts before gate. Final shipping figures follow the post-gate revision.
