Common questions about manuals, registration, and support for this brand.
W-Modbus is a wireless Modbus RTU architecture operating on the 2.4 GHz ISM band. It features frequency hopping for interference resistance and allows up to 100 nodes to communicate via a single gateway over distances up to 500 meters (open field) without data cables.
Many S+S sensors are calibratable. Manual offset adjustment is often possible via a potentiometer on the circuit board (e.g., ±50 hPa for pressure sensors) or through Modbus register settings, depending on the specific device model.
Configuration tools for RYMASKON products are typically available for download on the official S+S Regeltechnik website. These tools allow for easy connection via USB to adjust firmware, Modbus registers, and time programs.
For many S+S gateways, the factory default bus parameters are often set to 19200 baud, 8E1 (Even Parity, 1 Stop Bit), with bus termination deactivated. Always verify with the specific device datasheet.
Most devices accept 24 V AC or 15-36 V DC. However, specifics vary by model (e.g., controllers may accept 100-240 V), so checking the technical data on the device label is essential before connection.
