This module is used for transparent wireless connection of points on the RS485 bus. Thanks to the DIN rail design with integrated 230 V power supply, installation is quick and easy.
The module is supplied with a direct SMA antenna or an external self-adhesive antenna, which can be placed on the surface of the switchboard. The module is equipped with a screw terminal block and an RJ45 connector for connection to the RS485 line, which allows the use of standard cabling supplied with photovoltaic inverters.
Configuration is done using a 16-position rotary switch to set the radio channel (1–16). When establishing a wireless connection, it is necessary that all communicating units are set to the same channel.
Photovoltaic systems from the ANTIK Solartech portfolio are fully compatible with smart homes via the ANTIK SmartHome application. This integration allows not only to monitor and control the solar system, but also to easily connect and automate various smart devices in the home.
Purpose and use of the device
The module for wireless RS485 bus transmission is designed for transparent connection of two or more points on the RS485 bus without using cables .
A typical example is the communication between a photovoltaic inverter and a smart meter , where the module transmits data at a frequency of 2.4 GHz using LoRa modulation. This technology allows a range of up to 300 m in open space, 30 m in built-up areas.
Description of the module's indicator, configuration elements and connectors
The module is supplied with an SMA antenna, direct or external self-adhesive antenna, which can be placed on the surface of the switchboard. The module includes a screw terminal block for the RS485 line as well as an RJ45 connector, which allows the use of standard cabling supplied with photovoltaic inverters.
The module configuration is set using a single 16-position rotary switch that selects the radio channel (1 - 16). For proper function, both communicating units must be set to the same channel.
Typical application of modules
The system demonstrates wireless communication between a photovoltaic inverter and a smart meter using an RS485 bus. A standard cable carries the signal from the inverter to a wireless module that provides data transmission at a frequency of 2.4 GHz. The second module receives the signal and transmits it via a patch cable to the smart meter.
This system eliminates the need for long cable runs and enables reliable monitoring of energy consumption.
Reliable wireless RS485 transmission
The device enables transparent data transmission between two or more points of the RS485 bus via LoRa modulation in the 2.4 GHz band. The signal range is up to 300 m in open space and 30 m in built-up areas . LED indicators provide immediate visual control of data transmission.
- LoRa modulation for high reliability
- Range up to 300 m in open space, 30 m in built-up areas.
- LED indicators for checking data transfer
- Eliminates the need for long cable runs
Easy installation and configuration
The ATK-SMWRS1 module is designed for quick DIN rail mounting with an integrated 230 V power supply, which reduces the need for external power solutions and saves installation time. Configuration is easy thanks to the 16-position rotary switch that selects the radio channel. For error-free communication, both modules must be set to the same channel.
- Mounting directly on DIN rail
- Integrated 230 V power supply (max. 3W)
- Easy radio channel setting (1–16)
- Fast and reliable system commissioning

Possibility to purchase an antenna with higher gain and longer cable
For more demanding installations, where the basic antenna cannot provide sufficient signal, it is possible to purchase an external antenna with higher gain and an extended connection cable for the ANTIK Wireless RS485 SMW RS1 module. The antenna is connected via an SMA connector and, thanks to the longer cable, it can be placed outside the distribution board, which allows you to optimize its position relative to the signal source.
This solution is particularly suitable for installations:
- in built-up areas , where there is higher signal attenuation,
- with a larger distance between modules ,
- or when it is necessary to overcome obstacles indoors (walls, switchboards, technological spaces).
Using a more powerful antenna ensures more stable data transmission and reduces the risk of communication failures when transmitting data from the RS485 bus via 2.4 GHz LoRa modulation.
