PROPRIETARY HARDWARE · RTX-16-S3

The controller that turns any machine into data.

SyncBox RTX-16-S3: industrial controller with digital and analog I/O, 2x RS-485 Modbus RTU, RS-232, temperature and AC current sensors, programmable in RTX Script from the browser. Ethernet + Wi-Fi, MQTT with TLS and embedded REST API.

ARCHITECTURE

From the machine to the dashboard — three hops, no fragile middleware.

RTX lives in the machine's electrical panel. It reads signals, applies local logic, and publishes secure events to SyncBox. No industrial PCs, no proprietary gateways, no per-device licenses.

WHY EDGE IoT

Data that isn't captured doesn't exist.

Figures backed by McKinsey, Deloitte, and Gartner studies on the impact of industrial IoT and edge computing in manufacturing.

INVISIBLE DATA99%Of plant data goes unanalyzed without IoT connectivity
DOWNTIME−50%Unplanned downtime with IoT predictive maintenance
EDGE75%Of enterprise data will be processed at the edge, not the cloud
PRODUCTIVITY+20%Average productivity increase with connected smart manufacturing
THREE PILLARS

Hardware, RTX Script, and connectivity — designed together.

We didn't buy a third-party gateway and bolt on a cloud. RTX is born in Medellin: board, firmware, RTXVM, protocols, and platform designed by the same team.

01

Designed to live in the electrical panel, not on a desk.

Standard DIN rail, galvanic isolation on all inputs, digital and analog I/O, integrated temperature and AC current sensors. Developed and tested in real plants.

  • 16 DI + 16 DO isolated. 2.5kV isolated inputs via PCF8574. Relay outputs 10A / 250V AC with gold contacts.
  • Industrial ADC / DAC. 0-10V and 4-20mA inputs for pressure, level, and flow. 0-10V / 0-5V / 0-25mA outputs for valves and drives.
  • Integrated NTC and SCT sensors. 2 NTC temperature channels and AC current measurement 0-50A with split-core CT.
  • 2x RS-485 + RS-232. Two isolated Modbus RTU channels for meters and drives, plus UART for HMIs, PLCs, and scales.

Program industrial logic in RTX Script, from the browser.

The RTX serves its own IDE on port 80. Write logic in RTX Script — a language designed for industrial control with native Modbus, I/O, and telemetry functions. The RTXVM executes at the edge without depending on the cloud.

  • RTX Script + RTXVM. Proprietary language with native functions: modbus_read(), io.di(), sync.emit(). The VM executes at the edge at 1 kHz.
  • Native Modbus in the language. modbus_read, modbus_write, modbus_read_coil, modbus_ping — no external libraries or configuration.
  • Live debug. Variable watch, breakpoints, and live log while the machine is running.
  • Version control + OTA. Each deploy is versioned. Dual partition: if firmware fails, automatic rollback without intervention.

Native industrial connectivity — no gateways or middleware.

MQTT with TLS, embedded REST API, SSE for real-time monitoring, and integrated FTP server. All implemented in firmware, accessible from RTX Script without additional configuration.

  • MQTT v3.1.1 with TLS. Publishing with QoS 0/1, retain, and subscription to multiple topics. End-to-end encrypted.
  • Embedded REST API + SSE. HTTP server with JSON for configuration, status, and control. SSE for continuous real-time monitoring.
  • Ethernet W5500 + dual Wi-Fi. 10/100 Ethernet with magnetics and LEDs. 2.4 GHz Wi-Fi with WPA2/WPA3 in simultaneous STA/AP mode.
  • LoRaWAN and BLE ready. LoRa port for long-range LPWAN communication and BLE for wireless sensors (in development).

We send you an evaluation RTX to connect to your machine.

We lend you an RTX for 30 days. You hook it up to a machine, we help you configure the logic, and you see the data in SyncBox. If it works for you, we keep the conversation going.
