SmartRepeater – High-Performance RS485 Repeater for Airfield Ground Lighting Systems
The SmartRepeater from atg airports is a rugged, high-reliability RS485 signal repeater engineered specifically for airfield ground lighting (AGL) communication networks. Designed to work seamlessly with atg’s SmartSwitch and SmartMonitor systems, this advanced device plays a vital role in enhancing data transmission across long distances while maintaining the integrity and reliability essential in aviation environments.
Powered directly from the 6.6A secondary circuit of standard isolating transformers, the SmartRepeater offers a low-power solution (<2W) that simplifies AGL system integration. It automatically detects, boosts, and reclocks RS485 signals bidirectionally over a 2-wire communication bus, allowing for signal transmission up to 11km (6.5 miles) without the need for loopbacks. Multiple SmartRepeaters can be cascaded to form extended, secure communication links—ideal for large or complex runway and taxiway lighting systems.
Supporting up to 200 addressable devices on a single link, this RS485 repeater uses a proven asynchronous half-duplex communication protocol at 9.6KB, transmitted via a screened, single twisted pair fieldbus cable (SmartCable). The SmartRepeater ensures complete electrical isolation between communication and power circuits for improved communications reliability and integrity.
