Baud Rate up to 250 Kbps: Yacer Launches ATC Surveillance Signal Distributor

To meet the core requirements for efficient and reliable distribution of radar surveillance data in Air Traffic Control systems, Yacer's ATC Communication product line has developed and launched the HDLC-RSD Series Signal Distributor. This product is specifically designed to address the challenges posed by the widespread adoption of ADS-B receivers and the surging data volume from Secondary Surveillance Radar (Mode S). It breaks through the speed limitations of traditional devices, enabling high-performance data distribution.

The series includes two models to suit different deployment scenarios:

l HDLC-RSD-400: Features a compact enclosure design, supporting 1-to-4 distribution of synchronous/asynchronous serial ports, saving installation space.

l HDLC-RSD-800: Built in a standard 1U, 19-inch rack-mountable chassis, supporting 1-to-8 distribution of synchronous/asynchronous serial ports, and featuring dual redundant power supplies.

The main input port is compatible with both RS-232 and RS-422 interface standards, while all output sub-ports adhere to the RS-232 standard. This allows for quick deployment without additional configuration. The plug-and-play, zero-configuration design ensures stable operation upon connection, significantly reducing operational and maintenance costs.

In response to the industry trend of rapidly increasing data volume in ATC surveillance systems (requiring high baud rates for ADS-B receivers and Mode S secondary radar), Yacer has optimized the hardware architecture. The HDLC-RSD series now supports a maximum baud rate of 250 Kbps, far exceeding the traditional limit of 19.2 Kbps. This perfectly meets the demands for burst data transmission and low latency (ADS-B data transmission requires a baud rate of at least 115.2 Kbps), while also providing redundancy for future expansion, ensuring compatibility with evolving ATC system upgrades.
