STKNX Frequently Asked Questions (FAQs)

A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the layout symmetrical and avoid vias under the device. Use a 50-ohm microstrip transmission line for the RF output.
Follow the calibration procedure outlined in the application note AN5323. Perform a factory calibration, then perform a system calibration using the STSW-KNXGUI software.
The maximum cable length supported by STKNX is 700 meters, assuming a Category 5e cable with a maximum attenuation of 20 dB at 125 kHz.
No, STKNX is designed to operate with a standard KNX bus voltage of 30 V. Operating the device outside of this voltage range may affect its performance and reliability.
Use the STSW-KNXGUI software to monitor the bus traffic and diagnose issues. Check the device's configuration, bus voltage, and cable connections. Consult the STKNX troubleshooting guide for further assistance.
