Features
BT485 helps prevent signal reflections and electrical noise that can interfere with data transmission. Proper termination supports clearer communication between controllers, reducing intermittent faults and retries. This leads to more reliable system performance.
The small form factor allows BT485 to be installed directly at controllers without adding wiring complexity. Its straightforward design makes it easy to include during new installations or retrofits. This helps technicians quickly improve network reliability with minimal effort.
The BT485 Biasing Terminator improves BACnet MS/TP and EIA‑485 network reliability by reducing noise and signal distortion at network endpoints.
