Why TOP600B

Four reasons the field techs like it

Networking

Dual 2.5G plus cellular

Two Intel i226 2.5G ports with single/dual selection, and a B-Key 4G/5G slot with Micro-SIM — primary plus failover without a USB modem.

Supervision

Watchdog with sample code

A 0–255 second watchdog that ships with sample code — implement auto-recovery in your firmware instead of re-inventing the timer.

Thermals

28W, fanless by design

Alder/Raptor Lake-U/P at 28W across six i3/i5/i7 SKUs — passive cooling and wide-temp operation for sealed enclosures.

Legacy

Six COM, LPT or GPIO

COM1/2 RS232/485 with COM3–6 RS232, plus LPT or 16-bit GPIO and PS/2 — industrial protocols without adapters.

Where It Fits

Gateways and unattended sites

The TOP600B is built for machines that stay on and stay reachable: dual wired ports, a cellular slot and a watchdog that pulls the system back from a hang. Typical deployments:

Communications gateways: dual 2.5G for field and management VLANs, 4G/5G B-Key as the uplink when the site has no wired backbone.
Remote automation: wide-temperature DC 12–19V operation in enclosures with marginal cooling, watchdog guarding unattended restarts.
Data collection points: 6× COM with RS232/485 and LPT or GPIO for legacy instrument strings and local control lines.
