1Introd ction

1.1 User Man al p rpose

The purpose of this manual is to provide the instructions to quickly and simply install and

operate the SGW1-MB-NM

1.2 Prod ct Overview

The SGW1-IA3-MB-NM is a protocol converter that will convert the values send from a

NMEA 183 talker to Modbus registers. On the Modbus side it’s a slave that can be

connected to a Modbus master.

The supported NMEA statements are: GGA, VTG, MWV, XDR, ROT, VBW, DPT, HDM, HDT,

RMC, RMB, APB, DBT, MTW, MTA, RSA, VDO.

2Installation

2.1 Power S pply connection

The SGW1-IA3-MB-NM accepts a power supply in the range of +1 to 3 VDC. The positive

must be connected to terminal #5 and the negative to terminal #6, as can be seen in the

following image:

2.2 Serial Ports Connections

RS232 ports are DTE type. That means, data is transmitted through the TX terminal and is

received on the RX terminal. If you want to connect another DTE device you must cross the Tx

and Rx terminals.

2.3 Led Indicators

The SGW1-IA3-MB-NM has three LED indicators. One of them indicates that the device is

energized (Power). While the other two are each linked to the activity on the serial ports -

Modbus (A) and NMEA (B).

www exemys com Rev 2 7

3Config ration

The SGW1-IA3-MB-NM provides a command console for configuration via USB port.

To access it, the SGW1-IA3-MB-NM must be connected to a USB port on a PC and it must

have the Exemys branded terminal program called Exemys Console.

The driver for the USB can be downloaded from here: www.exemys.com/rmsrmdriver

The terminal type program can be downloaded from here: www.exemys.com/console

Once the driver and the terminal type program have been installed, the terminal must be run,

connect the SGW1-IA3- MB-NM to a USB port on the PC and go to the Connection -> USB

menu, a window will open with the description of all the Exemys products with USB found.

Select with double click the product to be configured and pressing ENTER will show a ">"

sign indicating that you can enter the configuration commands listed below.

disabled the SGW1-IA3-MB-NM will respond to errors with silence, otherwise it will

return an exception code.

MBPKTTOUT -

Modbus RTU packet expiration time: Modbus RTU packets are

separated from each other by a time interval. This parameter allows you to change the

maximum time, counting after the last byte of the packet, during which the SGW1-IA3-

MB-NM will assume that the packet has not yet been terminated. After this maximum

time, the SGW1-IA3-MB-NM will assume that the packet has finished arriving. The time

is entered in one-byte time units, with a minimum of 3 units. (Don’t change this value

unless you know exactly what it means)
