3 Introduction About this manual Purpose of this manual The purpose of this manual is to provide the instructions to quickly and simply install and operate the SGW1-MB-NM General Description of the Product The SGW1-MB-NM is a NMEA to Modbus converter. The device will read incoming NMEA sentences on one of its serial ports. Then it will parse the sentence and map the values into a Modbus register. The Modbus registers can be read with any standard Modbus master device. NMEA supported sentences are: Firmware 1.0 or higher: GGA, VTG, MWV Firmware 1.1 or higher: XDR Firmware 1.2 or higher: ROT, VBW, DPT, HDM, HDT, RMC, RMB, APB, DBT, MTW, MTA, RSA Power supply connection As you can see on the image the power source of the SGW1-MB-NM doesn t have a polarity. I you are using a DC power source you can connect either the + or terminal to terminal 1 and the other one on terminal 2. Serial ports connection The SGW1-MB-NM is a DTE. That means that it will send data out of its Tx terminal and receive data on its Rx terminals. If you connect it to another DTE you should cross Tx and Rx terminals. R6- AGO2015 3

4 The SGW1-MB-NM has three serial ports, each of them with a particular function. COM A This is the console port. You can use this port to configure the device as described on the Command Console section. Please follow this diagram to assemble a cable to connect the device to a computer s RS232 port. COM B You must connect the GPS or other NMEA device to this serial port. On the next diagram you ll find a connection example. Please read your NMEA device s manual to connect it properly.

5 COM C This is the Modbus slave port. You must connect your Modbus master device to this port. It s a RS485 port. LED indicators LED L1 will blink each time the devices receives a Modbus query. LED L2 will blink each time the devices receives a NMEA sentence. Modbus registers On the next table you will find how each NMEA sentence is mapped into Modbus registers. If your NMEA device is not sending one of the listed sentences the value read will be bit Modbus registers will be represented using big endian format (Most significative word comes first) Some NMEA registers will multiplied before converting to Modbus registers (x10, x10,000,000). Only the integer part of the values will be mapped in Modbus Parameters mark as ASCII will be represented by its ASCII value on the Modbus register. e.g.: A will be represented by the value 65. Date formatted as ddmmyyyy means that the date will represented using a decimal number where the first 2 figures will represent the day, 2 for the month and 4 for the year. e.g. the number represents November Time formatted as hhmmss means that the time will represented using a decimal number where the first 2 figures will represent the hours, 2 for the minutes and 2 for the seconds. e.g. the number represents 12:30:45 GGA Global Positioning System Fixed Data 40001:2 UTC Time hhmmss :4 Latitude x10,000,000 signed º 40005:6 Longitude x10,000,000 signed º GPS Quality Number of satellites Horizontal Dilution x :11 Altitude x10 meters/feet R6- AGO2015 5

You must connect the SGW1 to a computer s RS232 serial port and open a terminal program like Hyperterminal. Important: The serial port must be configured at 9600 bps, 8 data bits, no parity, 1 stop bit (9600,8,N,1) After powering the device on you should see this welcome message.
