Coming soon Built upon the Ebyte M31U Platform and mated with thier 16DO model. Swych brings you HaLow long range wifi connectivity with modbus speed and reliability. Lose the cabling, keep the performance and up time! Swych's HaLow Wifi brings this industrial controller to the forefront giving it TCP/IP connectivity without the copper, boasting an impressive 0.5km range in built up area testing and up to 1 km in a rural line of sight arrangement when used with higher gain aerials on HaLow. The Swych MD2 platform also has the standard 2.4Ghz Wifi stack for normal close range usage with standard routers on lower range use cases.

HaLow-R is a WiFi HaLow™ + WiFi 4 Indoor Extender / Router. It allows building long range, ultra-low power WiFi networks in sub 1 GHz license-exempt bands along with popular WiFi 2.4 GHz share Internet connection to laptop or smart phone. The perfect router for adding Swych MD-2 and M31-H units to your arsenal. Extender Mode Router Mode Extend existing home WiFi router signal and allow HaLow devices to connect Router Mode Extend existing home WiFi router signal and allow HaLow devices to connect As main home WiFi router and allow HaLow devices to connect.

The MD-2 is a versatile Modbus-to-IoT bridge host designed to adapt to your connectivity environment. It combines the ubiquity of WiFi with the extreme range of HaLow in a single DIN-rail mountable unit, giving engineers the flexibility to retrofit legacy infrastructure in any location. 1. Mode A: Standalone WiFi Edge Node When WiFi is available, the MD-2 acts as a fully autonomous modbus host. It requires no gateway and no external server. Embedded Web Server: Technicians can configure nodes and register maps directly from a browser-based UI hosted on the device. Direct REST API: Integrate directly with local SCADA, MES, or cloud dashboards. Send HTTP requests directly to the MD-2 IP address to read/write Modbus registers instantly. Ideal For: Indoor machinery, factory floors with strong WiFi coverage, and single-asset retrofits. 2. Mode B: Long-Range HaLow Node When assets are beyond the reach of WiFi (basements, outdoor fields, remote pump stations), When paired with the HaLow Router the MD-2 can run in HaLow Mode Seamless Aggregation: Pairs with most HaLow capable Routers to transmit data over hundreds of meters. Transparent Tunneling: The MD-2 acts as a transparent remote I/O extender, allowing the central Gateway or system to issue commands and collect state data without local network infrastructure. Ideal For: Remote facilities, agricultural assets, large factory's, sprawling campuses, and deep-indoor environments. 3. Universal Modbus Integration Regardless of the communication mode, the MD-2 remains a powerful industrial translator. Protocol Support: Modbus RTU (RS-485) Smart Polling: Configurable polling intervals allow you to balance data granularity with bandwidth/power usage. Bi-Directional Control: Supports both Reading (Coils, Discrete Inputs, Holding Registers, Input Registers) and Writing (Single/Multiple Coils & Registers), enabling active remote control, not just passive monitoring. The MD-2 eliminates the 'connectivity dilemma.' If you have WiFi, use it for high-speed, direct API control. If you don't, utilize HaLow for half kilometer range communication. With the same hardware, same register mapping, and same web-based configuration workflow, you can standardize on one device for every retrofit scenario.
