Working Principle Weak LCN signal from upstream coaxial cable enters repeater module. Internal circuit reshapes and amplifies the signal, restores waveform integrity and outputs regenerated signal to downstream LCN network segment. The isolation circuit separates two network segments. When one segment has cable fault, the fault cannot spread to another segment. Diagnostic circuit monitors signal status on both sides and sends fault alarm to LCN system.
Installation Requirements Install module at designated LCN network segmentation position; Fasten coaxial connectors tightly; Connect protective ground wire to cabinet ground bar; Separate LCN coaxial cable from power cable; Verify signal quality on both sides after installation.
Precautions for Use Do not exceed maximum quantity limit of repeaters on one LCN trunk; Do not connect high voltage signal to coaxial ports; Inspect coaxial cable aging regularly; Replace module when LCN signal distortion and packet loss occurs.
