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.
Page 8 GRD-MQ User Manual GRD 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.
Page 9 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: http://www.exemys.com/GRDconfig 8 / 84...
Page 10 GRD-MQ User Manual GRD Configurator 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.
Page 11 GRD-MQ User Manual GRD Configurator Once we enter monitoring the following screen will be displayed, in which we will be able to see the values of the input/output channels, the time, quantity of accumulated Historicals, the SIM in use and the states of connection of the equipment.
Page 12 GRD-MQ User Manual GRD Configurator We then configure the parameters with “File -> Save As” or with the icon to load them later when the GRD is connected. Once the configuration is saved, we can open it and load to multiple GRDs entering “File -> Open” or with the icon.
Page 13: Gsm & Gprs Connection
GRD-MQ User Manual GSM & GPRS Connection GSM and GPRS services configuration GSM Service Enabling SIM / GSM We first have to verify that the SIM has been selected and that it is within the corresponding GSM band. This is done in the following tab: GSM/GPRS -> General Configuration. Configuring the PIN on the SIM card If you place a SIM card with and activated PIN (security code), it must be configured in the GRD in order to have access.
Page 14 GRD-MQ User Manual GSM & GPRS Connection When the new configuration is applied, the GRD will try to unblock the SIM Card with the entered PIN. If this is the correct one, the registration process will be initiated. To verify if the SIM card that has been placed is blocked or if the configured PIN is correct, check the SIM status in the monitoring option.
Page 15 GRD-MQ User Manual GSM & GPRS Connection Configuring the cell phone operator The following step is the correct configuration of the GPRS service. For this, you have to tell the equipment the corresponding operator of the installed SIM card or the APN parameters, user and password.
Page 16 GRD-MQ User Manual GSM & GPRS Connection The GPRS parameters can be saved so they won’t have to be entered every time the GRD is used with the same cell phone operator. To do this you have to go to “Software Configuration -> Properties”. A window will be displayed on which we will be able to enter a name to recognize the configuration, APN, user and password.
Page 17: Grd-Mq To Broker Connection
GRD-MQ User Manual GRD-MQ to Broker Connection Connection between GRD-MQ and the broker Configuration of the GRD-MQ to broker connection Communication with the broker uses a TCP/GPRS connection. To be able to establish the connection it is necessary to: Place the antenna correctly and ensure GPRS coverage. Place the SIM card, and, if necessary configure PIN.
Page 18 GRD-MQ User Manual GRD-MQ to Broker Connection CA certificate only: You must upload the CA certificate for validation Self signed certificates: You must upload CA certificate, client certificate and client key For GRD-MQ to be able to use "CA certificate only" and "Self signed certificates" the GRDs clock must be setted properly.
Page 19 GRD-MQ User Manual GRD-MQ to Broker Connection SMS password This password can be used to protect remote SMS configuration Monitoring the GRD-MQ to broker connection Monitoring the connection in the GRD-MQ To verify whether the entered configuration into the GRD-MQ is the correct one we have the possibility of monitoring the status of the connections and the signal.
Page 20 GRD-MQ User Manual GRD-MQ to Broker Connection Selected but not resent: In models with SIM detection it indicates that the SIM is not placed. Pin Required: This message appears when a SIM card requires a PIN. PIN Error: This message shows that the PIN entered is incorrect. If a PIN is entered incorrectly 3 consecutive times, the SIM card will block.
Page 21 GRD-MQ User Manual GRD-MQ to Broker Connection In general, each one has a specific motive although it depends on the connection on the server side for the indication to be correct, even so, any of the these 3 errors indicate a problem in the connection.

Page 24: Inputs/Outputs
GRD-MQ User Manual Physical Inputs/Outputs Physical Inputs/Outputs Depending on the model, the GRD/cLAN can have or not physical inputs/outputs. We will now see the types of inputs/outputs that we can have and which parameters we can configure of each one. It is important to point out that this configuration is applicable only to physical inputs and not to inputs from the Modbus queries.
Page 25 GRD-MQ User Manual Physical Inputs/Outputs The value of the anti-debounce can be configured between 1 and 250 ms. On devices with more than 8 digital inputs, inputs higher than 8 will have an anti-debounce time fixed at 250 ms. The counting divisor can take a value between 1 and 1000. On the cLAN2205-XF, cLAN2205-MQ, GRD3621-XF-3G, GRD3621-MQ-3G, GRD3625-XF-3G and GRD3625-MQ-3G you must configure wether a IO terminal will work as an input or as an output Take special care not to apply direct voltage to a terminal configured as an output and in ON state.

Page 40: Channels
GRD-MQ User Manual Channels Channels Channels are the media through which information about inputs/outputs of the MW (or broker) equipment are sent or received. These channels can be linked to physical entry points of the equipment like MODBUS queries according to their compatibility with the channel.
Page 41 GRD-MQ User Manual Channels After selecting the desired channel and among any of the 4 you’ll have the option to add or remove, it is important to point out that within each channel only inputs and outputs compatible with that channel will appear.
Page 42 GRD-MQ User Manual Channels To erase a channel you only have to click on the “Del” button of the channel previously selected. Since firmware GRD-3G 1.9+ and cLAN 2.8+ and new channel source called "Mem" is added This source is linked to a 100 position volatile memori that can be read and wrote from the script using read_io 305 and write_io 305 The signal level can be configured as analog channel source in GRD-XF-2G with firmware 4.0.0 or higher.
Page 43: Reports And Historical Records
GRD-MQ User Manual Reports and Historical records Reports and Historical records - MQTT publish There are 2 types of information that the GRD-MQ/cLAN-MQ can send. On one side, we have the reports that contain the real values of inputs and outputs updated according to the criteria configured in the device.

Page 45 GRD-MQ User Manual Reports and Historical records the first time it is connected, it sends a message with all configured reports. Digital inputs channels reports: The following figure shows the configuration screen of the digital inputs reports: Report by change If a report by change of a digital input cannel is enabled, a change of value will generate a message that will be sent to the broker.
Page 46 GRD-MQ User Manual Reports and Historical records Report by change The report by change is enabled in the channels we want to be updated in the broker every time that the signal changes The "percentage" report will report if the input changes a percentage from full scale. The full scale value will depend on the input type.
Page 47 GRD-MQ User Manual Reports and Historical records Pulse inputs channels reports: The pulse channels have 2 types of reports. On one side the reports by performed count and on the other the temporary report. Report by count In the counts number report the device sends a message to the broker each time the desired input counts a number of pulses from the last report of this channel, by counts or by time.

Page 49 GRD-MQ User Manual Reports and Historical records By alarm This criterion defines an operational band through a maximum and minimum. When the analog input exceeds the maximum value a Historical is generated by maximum, when the analog input is lower than the minimum a Historical by minimum is generated and when the analog input passes from a maximum value or from a minimum value to a normal value between both a Historical by normal value is generated.
Page 50 GRD-MQ User Manual Reports and Historical records It is not possible to configure a value of hysteresis greater than the difference between the maximum and minimum, and also a maximum smaller than a minimum. We can also associate a digital output channel to the alarm event by maximum and another one of alarm by minimum, this means that when the analog input in the maximum range will activate an output and in the minimum another one.
Page 51 GRD-MQ User Manual Reports and Historical records Pulse input channels historical records The pulse channels can also generate Historicals in a specific time that can be configured the same way as in the other channels, as it is shown in the following figure. We can also decide if once the Historical is generated, we want the counter reset to 0 or not.
