Factory, campus, and building-BA edge cabinets: half-width 1U, single 10/100M port, hardware-stamped NTP, OCXO, and hardware time outputs (1PPS / IRIG-B / programmable pulse). Typical order model SY-4096-GN-O-S.

Can we order SY-4096 as shipping stock today?

Do not write it as broadly shipping. Status is coming soon; datasheet v1.1 is pre-gate. For immediate cabinet delivery use SY-1231 and bridge until 4096 ships.

Does 4096 replace the SY-8640 multi-port flagship?

No. 4096 stays single-port and does not include dual-NIC failover or dual PSU as standard. Separated mgmt/timing, multi-gigabit, or dual supply → roadmap SY-8640.

What Ethernet and client numbers can we cite?

Still 1× RJ45 10/100M (NTP and Web on the same port). Identity cap defaults to about 200 (selection cap, not a field-density guarantee). Do not publish unmeasured req/s before gate; contract the shipping datasheet.

How do hardware time outputs differ from the 1231?

4096 ships 1PPS (BNC), IRIG-B DCLS, and a programmable pulse, edge-aligned to the disciplined second. 1231 offers TTL 1PPS, minute PULSE, and Modbus—no IRIG and no OCXO.

SY-4096

NTP Time Server · Stratum 1

Typical order model: SY-4096-GN-O-S Coming soon

Nameplate: TemporaSync · SY-4096

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 SY-1231); or multi-port / dual-supply plant flagship (see SY-8640).

Selection help Download datasheet How to choose

vs 1231: 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 8640 multi-port / dual-supply flagship. Do not publish unmeasured req/s before gate; contract the shipping datasheet. Aligned with datasheet v1.1 / website copy.

How it differs from the other model

The 4096 code is 2¹²—a cabinet capacity name (slave-clock mnemonic). Contract ID-cap / reply rate still follow the shipping datasheet; do not treat 4096 as a measured client count. Below: SY-1231 protocol SKU. Above: SY-8640 time-origin flagship. Reserved: SY-8192 = next cabinet, 2× slaves.
