Product information

Description

The MikroTik KNOT (RB924I-2ND-BT5&BG77) is an IoT gateway that provides low-bandwidth cellular connectivity using NB-IoT and CAT-M technologies, combined with Wi‑Fi 2.4 GHz, Bluetooth and two 10/100 Mbps Ethernet ports with PoE-in and PoE-out. Designed for DIN-rail mounting and equipped with a QCA9531 650 MHz processor, 64 MB memory, Micro‑USB and RS-485 support, the device bridges wired Modbus sensors and BLE devices to TCP/IP networks via HTTPS and MQTT while supporting NanoSIM cards and common wireless standards (IEEE 802.11a/b/g/n).

Advantages

KNOT offers low operational costs through NB/CAT‑M cellular connectivity supported by many mobile operators, multiple protocol support (Modbus TCP conversion, BLE advertisement forwarding, TCP bridging), and flexible physical interfaces including Bluetooth, 2.4 GHz Wi‑Fi, two Ethernet ports and Micro‑USB. The unit includes a DIN-rail mount for easy integration into cabinets and provides filters to forward only relevant Bluetooth packets.

Suitable for

Connecting wired Modbus sensors (electricity meters, relays) to Modbus servers over TCP
Asset tracking and telemetry using BLE advertisement tags (iBeacon, Eddystone, or custom)
Remote monitoring of vending machines, cold‑chain sensors and agricultural equipment
Backup management channel for Ethernet networks or low‑bandwidth remote sites
Industrial and outdoor cabinet IoT deployments requiring DIN‑rail mounting

Key specifications

Model: MikroTik KNOT (RB924I-2ND-BT5&BG77)
Cellular: NB‑IoT and CAT‑M support
Wireless: Wi‑Fi 2.4 GHz IEEE 802.11a/b/g/n, Bluetooth (BLE)
Ethernet: 2 × 10/100 Mbps ports with PoE‑in and PoE‑out
Processor & memory: QCA9531 650 MHz, 64 MB RAM
Interfaces: Micro‑USB, RS‑485, NanoSIM slot
Mounting: DIN‑rail; Protection class: IP20
Colour: White

How to use

Install the KNOT on a DIN rail inside the cabinet and insert a NanoSIM if using cellular connectivity. Connect Modbus sensors to the RS‑485 or wired Ethernet devices to the LAN ports; configure Modbus‑to‑TCP bridging or enable BLE advertisement forwarding in the device web interface. Configure HTTPS or MQTT endpoints for forwarding sensor data to cloud or local servers, and set up packet filters to forward only relevant BLE advertisements.

Usage recommendations

Use an NB/CAT‑M monthly plan for low data cost; monitor daily data usage as simple telemetry (temperature, liquid level) typically requires only a few megabytes per day. For outdoor or industrial installations, mount the device inside a suitable enclosure to meet environmental requirements since the device has IP20 protection.
