Introduction to the GRD-MQ

Purpose of this manual

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

GRD-MQ equipment (3G models)

The installation of the GRD-MQ also implies the installation of middleware and eventually any other

application depending on the intended use for the system.

Telemetry solutions GPRS with GRD-MQ

The GRD-MQ has multiple uses. These are the most common uses that will guide you to read this

manual.

GPRS RTU/Datalogger to MQTT broker

Physical inputs/outputs

Modbus inputs/outputs (embedded Modbus master)

Serial port data (using script programming)

Local input/output control (using script programming)

Publish current values (reports) and timestamped values (historics) using MQTT

Receive commands/order from the MQTT broker using subscription

GPRS RTU accessible by Modbus

Physical inputs/outputs

Serial port data (using script programming)

Modbus protocol to read input/outputs remotely

Remote Access to serial port

Remote serial port via MQTT broker

SMS alarms/control

Physical inputs/outputs

Modbus inputs/outputs (embedded Modbus master)

Serial port data (using script programming)

Local input/output control (using script programming)

GPRS RTU/Datalogger to MQTT broker

There are hundreds of types of sensors that can be contacted directly to the GRD-MQ inputs to measure

different types of variables. Depending on the GRD-MQ model, sensors could be used to deliver signals

in 0-10V, 4-20mA or pulses, or simply connect different devices to their inputs/outputs. The GRD-MQ can

also be configured as Modbus master and queries can be made to different slaves to expand its

inputs/outputs.

The GRD works as a datalogger, creating records with timestamp with the value of the built-in or external

I/Os and publish them to the broker

The GRD can also be used to do a local control over its inputs/outputs using the script programming

feature.

Nota: Exemys does not provide the MQTT broker

For this type of solution the following procedure must be followed:

Have an MQTT broker available

Install the GRD.

Install the configuration software (“GRD Config”), this application will allow us to configure all GRD

parameters locally or remotely.

Enable the SIM card and configure the APN of your telephone network

Establish a connection between the GRD-MQ and the broker

Configure the inputs/outputs in the GRD according to their use:

Physical inputs/outputs

External Modbus inputs/outputs.

Configure the GRD-MQ serial port.

Configure the “Embedded Modbus master" and the queries we want it to make.

Configure the topics and formats to publish an enable reports and historicals to publish

Remote serial port

This procedure will allow you to send and receive data to and from the serial port (RS232/RS485) using

publish and subscribe.

For this type of solution the following procedure must be followed:

Install the GRD.

Install the configuration software (“GRD Config”) V9.1+, this application will allow us to configure all

GRD parameters locally or remotely.

Enable the SIM card and configure the APN of your telephone network

Establish a connection between the GRD-MQ and the broker

Configure the serial port in Remote mode

Configure the serial ports publish and subscribe topics

SMS alarms / control

The GRD-MQ can send SMS alarms to up to 8 recipients based on the value of its inputs.

You can also send and SMS to the GRD-MQ to ask for the value of a particular input/output or to

activate an output.

This inputs/outputs can be physical or Modbus signals.

The SMS feature can be used together with GPRS solutions.

Script programming can also be used for customized solutions where the standard criteria to send SMS

alarms is not enough.

For this type of solution the procedure below must be followed:

Install the GRD-MQ

Install the configuration software via USB (“GRD Config”), this application will allow us to configure

all GRD-MQ parameters locally or remotely.

Enable the SIM card

Configure the inputs/outputs in the GRD-MQ according to their utilization:

Physical Inputs/Outputs

External Modbus Inputs/Outputs.

Configure the GRD-MQ serial port.

Configure the “Embedded Modbus master" and the desired queries.

Installation of the SIM card

Requirements

For the correct operation of the equipment the Micro SIM card must meet the following requirements:

A subscription to GSM and GPRS/3G services

It must be cleared to be installed in any equipment (some SIM cards can only be installed in the

equipment where they were purchased).

Verify the telephone number assigned to the SIM Card.

You must know the data to access the GPRS/3G network of the telephone operator corresponding to

the SIM card (APN, user, password). These data are preloaded in the GRD for Movistar Argentina,

Telecom Personal Argentina and Claro Argentina. If you use another operator please contact

support@exemys.com.

GRD-MQ configuration software – GRDconfig

GRDconfig is the application program used to configure the GRD equipment.

This application was developed with an easy-to-use feature in mind to configure and monitor GRD-MQ

equipment.

The Configurator is supported on the following platforms: Windows 2003, XP, Vista, 2008, 7, 8 and 10

(32 and 64 bits).

Java Runtime Environment 1.8 (32 bit version) must be installed (available free in www.java.com).

Installation

For installation follow these steps:

Run the installation software (download it from here www.exemys.com/grdconfig)

A welcome screen will be displayed, then follow the instructions of the Installation program which will

request the necessary information to complete the installation. Click on “Next” to continue.

Destination folder: Select the folder for the installation of the application program.

Wait for the installation program to copy all necessary files onto the hard disk, and press “Finish” to

end the installation process.

Once installed you will see in the Programs menu a folder called Exemys. Inside the folder you will find

another folder called GRDconfig; this folder contains the GRDconfig and Uninstall icons.

USB Driver Installation

After intalling GRDconfig all drivers will be automatically installed. In case you still have problems you

can manually install the drivers from here:

“C:\Program Files\Exemys\GRDconfig\DriverFTDI\InstallDriver.exe"

If you don't install the drivers you won't be able to configure the GRD-MQ and will get this message:

General description of the Configurator

The following figure shows the main screen of the Configurator.

Configuration of the USB port

Once the software is installed you won’t have to configure any parameter of the USB port since this port

recognizes automatically the COM in which the GRD is connected.

You can only connect up two GRDs to the PC at the same

time.

Establishing the connection with the GRD

To connect to the GRD-MQ you must have the PC connected to the GRD-MQ using the cable described

in “GRD models – Installation”.

To establish the connection select the menu option “Communication -> Open Local Connection” or press

the button.

If the communication fails verify that:

The cable connecting the PC to the GRD is the correct one.

The GRD is on.

The driver is installed correctly.

After a few moments you will be able to see that the state of the connection changes to connected and

will also indicate the COM port of the connection.

Getting GRD parameters

To obtain the parameters of the equipment you will have to press the “Get Configuration” button and all

the GRD parameters will be displayed indicating on the first screen, the model, IMEI, etc.

You will always have to read the GRD parameters to be able to modify the parameters or for monitoring

purposes.

If the Configurator finds an unknown model it will not enable

any of the screens. Download the latest GRDconfig release

from here:

Sending parameters to the GRD

If you want to send to the GRD any change in the configuration press the “Send Configuration” button,

please note that to the right of the button we have a combo that when displayed allows us to send the

standard configuration plus the change of GSM band in case of necessity, this is because this parameter

is not sent by default.

It is very important to take into account that the GSM band in

which the GRD will operate has to be configured according to

the geographical area.

Monitoring

To access the monitoring area where all the GRD parameters can be seen, you should press the

“Monitor” button.
