Making Communication as Simple as Building Blocks.
Two radar data comparison & selection units
Each unit selects 1 output from 2 RS-232/422 input
Supports sync HDLC protocol and async UART mode
Automatic switching upon failure of any communication node in the preceding link
1U, 19-inch standard rack-mounted chassis
Dual power supply redundancy, low power consumption, fanless design
Overview
Introduction
Yacer HDLC-SWITCH ATC Surveillance Signal Comparator features two independent selection units. Each unit is equipped with full-link status awareness, enabling real-time comparison and optimal output selection between two incoming ATC surveillance signals (SSR/ADS-B).
Housed in a 1U 19-inch standard rack-mountable chassis, the device features a low-power, fanless design for high reliability and supports redundant power supplies, making it ideal for critical ATC applications.
Applications
Air Traffic Management (ATC)
Signal selection/comparison for ATC PSR, SSR & ADS-B
Radar signal access for ATC automation systems and surveillance systems
Synchronous HDLC serial port selection/comparison
Asynchronous UART serial port selection/comparison
