Feature:1. Application: The NMEA digital signal synthesizer is applicable for 1 input series, replacement for LOWRANCE, replacement for RAYMARINE, replacement for GARMIN, for SIMRAD radar.2. Output: Each serial port input baud rate can be automatically selected 2400115200, the composite output signal baud rate defaults to 38400 (The output baud rate can be set to 115200).3. Function: NMEA digital signal synthesizer provides 4 serial port data input (NMEA0183 Protocol) and synthesizes into 2 serial port output (NMEA0183 Protocol).4. Practical: The NMEA Digital Signal Synthesizer is a valuable tool for the marine industry, enabling efficient testing, development, and troubleshooting of NMEA based marine electronic systems.5. Input Statement Format: The first serial port statement is a post statement, the second is a GPS statement, the third is the AIS statement, and the fourth is a log statement.Specification:Item Type: NMEA Digital Signal Synthesizer.Material: ABSFunction Overview:NMEA digital signal synthesizer (Model: HC-402) provides 4 serial port data input (NMEA0183 Protocol) and synthesizes into 2 serial port output (NMEA0183 Protocol), each serial port input baud rate can be automatically selected: 2400-115200 , the composite output signal baud rate defaults to 38400 (The output baud rate can be set to 115200).This product is suitable for: devices with only 1 input series, such as: LOWRANCE, RAYMARINE, GARMIN, SIMRAD radar, etc.e.g.:1) Input Statement Format:The first serial port statement is a post statement$HEHDM, 282.0, T*3EThe second serial port statement is a GPS statement.$ GPRMC, 090951, A, 2304.5504, N, 11325.8370, E, 000.0, 000.0, 120917, 002.6, W * 61The third serial port statement is the AIS statement!
