SDLC-BOARD Embedded Development Board - Yacer - Building Blocks of Communication！

Overview

Introduction

The Yacer SDLC-BOARD Embedded development board provides HDLC synchronous full feature serial ports, asynchronous UART, CAN bus and Ethernet interface to achieve the protocol conversion between different interfaces.

It adopts small size and terminal interface design, which is especially convenient for users to realize system integration.

The on-board application CPU is used by users for secondary development to realize seamless integration of business software and communication software.

Applications

• Conversion between synchronous and asynchronous serial ports

• Protocol conversion between the serial port and Ethernet

• Conversion between CAN bus and serial port

• Conversion between CAN bus and Ethernet

• Train Control and Monitoring System (TCMS), Train Communication Network (TCN)

• Telemetry, measurement and control data acquisition and transmission

• Satellite, radio data transmission

• Air Traffic Control (ATC), Air Traffic Management (ATM)

• Embedded application and development

Features

• Dual 10/100M Ethernet, support Ethernet switching and dual IP function

• Dual synchronous/asynchronous serial port with isolation, RS-422 full-duplex and RS-485 half-duplex optional

• One extension interface with isolation, optional RS-422, RS-485 serial port or CAN bus interface

• All serial ports support synchronous HDLC or asynchronous UART working mode

• The coding formats support NRZ, NRZI, DBPL, Manchester and Diff-Man

• On-board application CPU provides secondary development for users

• Complete isolation protection, industrial wide temperature

• Easy integration: small size, terminal interface, 5 ~ 17V wide voltage power supply
