NMEA数字信号合成器使用说明书

HC-402

一 、功能概述

NMEA数字信号合成器（型号：HC-402）提供4路串口数据输入(NMEA0183协议)并合成为两路串口输出(NMEA0183协议),每路串口输入波特率可自动识别：2400－115200，合成输出信号波特率默认为38400(输出波特率可通过3位拨码开关设置)。

本产品适用于：只有一个串口输入的设备，例如：LOANCE,MADCMO、GARMIN、SIMRAD雷达等,同时可作为波特率转换设备。

二、使用说明

1 、串口输入信号需符合NMEA0183协议格式语句；例如：艏向语句$HDHDT,123.0,T*2E。

2 、每路串口输入信号合成输出时将保持原有的输入格式，如原有的格式如下：$HDHDT,123.0,T*2E ；输出也相同，但波特率将变成38400；

例如：

1）输入语句格式：

第一路串口语句为航向语句

$HEHDM,282.0,T*3E

第二路串口语句为GPS语句$GPRMC,090951,A,2304.5504,N,11325.8370,E,000.0,000.0,120917,002.6,W*61

第三路串口语句为AIS语句

!AIVDM,1,1,0,A,16:FDnPP0087<LP==n>U?gwl2588,0*29

第四路串口语句为计程仪语句

$HCVBW,20.3,1.5,A,23.1,1.2,A,1.1,A,1.5,A*4A

2）输出语句格式：

输出信号分两路同时输出，输出语句为合成后的所有语句总和，信号格式符合 RS-422标准，波特率为38400。

$HEHDM,282.0,T*3E

$GPRMC,090951,A,2304.5504,N,11325.8370,E,000.0,000.0,120917,002.6,W*61

!AIVDM,1,1,0,A,16:FDnPP0087<LP==n>U?gwl2588,0*29

$HCVBW,20.3,1.5,A,23.1,1.2,A,1.1,A,1.5,A*4A

3、输出波特率设置:

   转换器输出波特率默认设置波特率为38400;如需调整输出波特率需打开转换器盖，通过调整PCB板上的3位拨码开关设置。

NMEA Digital Signal Synthesizer

 (HC-402)

1、 Function overview

NMEA digital signal synthesizer (model: HC-402) provides four serial port data inputs (NMEA0183 protocol) and synthesizes them into two serial port outputs (NMEA0183 protocol). Each serial port input baud rate can be selected automatically: 2400-115200, and the synthesized output signal baud rate defaults to 38400 (output baud rate can be set).

This product is suitable for: only one serial port input equipment, such as: LOWRANCE, RAYMARINE, GARMIN, SIMRAD radar, etc. It is also a baud rate converter.

2、 Instructions for use

1 、Serial input signal shall conform to NMEA0183 protocol format statement; for example: heading statement    $HDHDT,123.0,T*2E。

2 、The original input format will be maintained when the input signals of each serial port are synthesized and output. For example, the original format is as follows: $HDHDT,123.0,T*2E ；The output is the same, but the baud rate has changed to 38400;

For example:

 1) input statement format:

The first serial port statement is heading statement

$HEHDM,282.0,T*3E

The second serial port statement is a GPS statement

$GPRMC,090951,A,2304.5504,N,11325.8370,E,000.0,000.0,120917,002.6,W*61

The third serial port statement is AIS statement

!AIVDM,1,1,0,A,16:FDnPP0087<LP==n>U?gwl2588,0*29

The fourth serial port statement is a log statement

$HCVBW,20.3,1.5,A,23.1,1.2,A,1.1,A,1.5,A*4A

2）Output statement format：

The output signal is output in two ways at the same time. The output statement is the sum of all statements after synthesis. The signal format conforms to RS-422 standard, and the baud rate is 38400.

$HEHDM,282.0,T*3E

$GPRMC,090951,A,2304.5504,N,11325.8370,E,000.0,000.0,120917,002.6,W*61

!AIVDM,1,1,0,A,16:FDnPP0087<LP==n>U?gwl2588,0*29

$HCVBW,20.3,1.5,A,23.1,1.2,A,1.1,A,1.5,A*4A

3、 Output baud rate setting:

     The baud rate of the converter output is 38400 by default; to adjust the baud rate of the output, turn on the converter, and adjust the setting of the dial switch on the PCB.
