Air Traffic Management

The leading synchronous HDLC communication protocol provides mature and stable air traffic control communication products, including communication servers, protocol converters, splitters and other products, and realizes the access, conversion, transmission, distribution and other functions of air traffic control secondary radar (SSR), ADS-B and other synchronous serial port data.

HDLC-ATC Air Traffic Data Communication Server

2x or 3x 100M Ethernet interfaces and 4x, 8x or 16x synchronous HDLC serial ports (2x of which support asynchronous UART) to realize protocol conversion between serial ports and Ethernet ports.

HDLC-RSD Synchronous Serial Port Splitter

The Yacer HDLC-RSD Synchronous Serial Splitter is an active data distributor with a maximum baud rate of 250 Kbps, capable of 1 in 4 and 1 in 8 data sharing for HDLC synchronous serial ports

HDLC-USB Portable Protocol Converter

2x multi-protocol synchronous & asynchronous serial ports and 1x 10/100M Ethernet interface to achieve the protocol conversion between the serial port and the Ethernet interface.

HDLC-ETH Serial Ethernet Converter

4x synchronous / asynchronous serial port and 1x or 2x 100M Ethernet interfaces to realize the protocol conversion between serial and Ethernet.

HDLC-LCM Low Power Communication Module

4x synchronous / asynchronous serial ports and 2x 100M Ethernet interfaces to realize protocol conversion between HDLC, UART and Ethernet.

TECHNICAL DOCUMENTS

Introduction to HDLC Protocol

HDLC protocol, sometimes known as SDLC protocol, is a link layer protocol widely used in industry communications. The HDLC protocol specification is referred to the ISO / IEC 13239 standard document.

The Selection and Configuration of Synchronization Clock for HDLC Protocol

Synchronous HDLC serial communication, different from ordinary asynchronous communication, the clock signal plays an important role, only the sender and receiver use the same clock, can achieve highly reliable data transmission.

Air Traffic Control (ATC) Secondary Surveillance Radar (SSR) DTE and DCE synchronous serial port definition

Design and Implementation of HDLC Synchronous Serial Port for ATC Radar

The ATC radar data network uses the HDLC protocol to transmit target data, and the ATC radar and ADS-B equipment must be able to support the HDLC protocol and provide multiple synchronized serial ports for outputting radar data.
