•Connect GND and Shield cable first, and disconnect them last.
2.3 GSM/GPRS Configuration
Note: For SIMs not supplied by Logic Energy Ltd, GPRS config parameters must be set up before use.
To configure the LeNETmobile for your own SIM, you need the GPRS APN, username and password
from your network provider, plus the radio band that you provider uses (e.g. GSM900).
Moreover you also need SD card reader (this is built into some PCs) and a micro-SD adapter in order to
read micro-SD card.
1. Ensure the LeNETmobile is switched off. Unscrew and remove the end cover from the
LeNETmobile enclosure. Remove the micro-SD card from the LeNETmobile by gently pushing it
in to unlatch it.
2. Insert the micro-SD card into your card reader, and browse to the config_backup folder on the
card. Open the config.txt file in a text editor such as Notepad.
3. The file config.txt specifies the GPRS config parameters to use for the GSM network
connection. An example config.txt file might look like this:
[GPRS]
apn=yourapn.com
usr=username
pwd=password
bnd=0
4. Change the APN parameters to match those from your provider. For example:
[GPRS]
apn=internet
usr=web
pwd=web
bnd=0
5. Set the bnd parameter, as shown in the table below
bnd=0
GSM900 and GSM1800/DCS1800 (Most countries outside the US/Can
ada)
bnd=1
GSM900 and GSM1900/PSC1900
bnd=2
GSM850 and GSM1800/DCS1800
bnd=3
GSM850 and GSM1900/DCS1900 (USA/Canada and some of South America)
6. Save the file, and then copy (not move) the file to the root (top level) folder of the SD card.
7. Eject the card from the reader and insert it into the LeNETmobile by pushing it into the socket
until it clicks and locks into place. Then switch ON the LeNETmobile.

2.4 Power Supply Setup
Depending on the installation type, there are various ways to power the LeNETmobile.
•For remote sites and long term monitoring, a PV kit (solar panel and battery) is recommended.
•For cost-conscious installations, a replaceable industrial alkaline battery pack can be used.
•For indoor or energy metering systems, a mains power supply is suitable.
Note:
The power supply positive wire connects to the LeNETmobile
PWR+
terminal, and the negative
wire connects to the GND terminal.
2.4.1 PV Kit Power Supply
The LeNETmobile can be powered from a 6V or 12V rechargeable battery and PV panel kit for reliable
long-term operation on remote sites.
•The solar panel works best when it receives full sunlight, so mount it away from fences,
buildings, trees or other obstructions that may cast shadows on it.
•The panel should be mounted facing south in the Northern Hemisphere, and facing north in the
Southern Hemisphere for maximum sun exposure. The vertical angle depends on latitude (usually
about 30º angle)
•Mount the enclosure and panel on the mast, mount pole or wall with appropriate brackets.
•Connect the PV kit output cable to the LeNETmobile power terminals: “+” (red or white wire) to
LeNETmobile “PWR +” and “–” (black wire) to LeNETmobile GND.
2.4.2 Mains Power Supply
The LeNETmobile can be powered from any mains power supply that can provide up to 2 Amps at
typically 9 Volts. This is typically a plug-pack or DIN-rail switching supply. Connect the supply output
directly to the LeNETmobile power terminals, and avoid use of excessively long cables.
2.4.3 Battery Power Supply
The LeNETmobile can be powered from an alkaline battery pack consisting of 6 D-cells. Only use good
quality industrial cells for maximum life. These will typically last around 3 months. Always use
LeSENSE to monitor the battery voltage, and/or set up a LeSENSE alert to warn of low battery. The alert
trigger point should be set at 7.5V. See the LeSENSE user guide for details of how to configure alerts.

2.5 Installation Checklist
Before powering up the LeNETmobile device, check that the installation is correct. Following is the quick
checklist for installation:
1. Make sure the sensors connections are sound and the jumpers are configured correctly for each
port connected to signal source/sensor.
2. For wind applications, the primary/top anemometer must be connected to port A1 and the
primary/top wind vane must be connected to port D5.
3. An active GSM (Cellular) SIM is inserted in the GSM module. Also make sure the antenna is
connected to the module. If using an external antenna, ensure it is securely mounted, and not
obstructed by metal enclosures or masts and preferable vertical position.
4. If you are using your own SIM, then make sure that micro-SD card contains the correct GPRS
settings in the configuration file.
5. Power up the device using appropriate powering source.
Note:
Once the system is in operation, check that the device communicates with the server, and that the
server shows new data each measurement interval. Also check that data makes sense before leaving the
installation site.
2.6 LEDs Status
There are two LEDs on LeNETmobile to indicate its operating state. They are:
•Activity LED (GREEN LED-gear wheel symbol) blinks every 1 second (or few seconds) during
normal operation of the system, while the other LED stays OFF. This LED also indicates memory
card access.
•GSM LED (AMBER LED-antenna symbol) flashes during the communication cycle only, while
the other LED stays OFF.

APPENDIX A SENSORS SPECIFICATION
A-1 Energy Meter Specification
The following are the main points when checking the compatibility of an energy meter with
LeNETmobile.
1- The energy meter should have pulse output feature.
2- Any standard pulse output is compatible with LeNETmobile.
3- The pulse output rate varies depending on the amount of energy flow through the meter. For most
scenarios, a pulse rate of 1000 imp/KWH gives advanced resolution.

APPENDIX-B

APPENDIX B CONNECTION DIAGRAMS
B-1 Energy Meters & Analogue sensors
LeNETmobile is capable of monitoring upto 8 Energy meters (such as KWH meters, Heat meters, Flow
meters) connected to ports A1-A4 and D1-D4. Moreover it can also monitor 6 analogue sensors
connected to ports D5-D10.

APPENDIX-B
Installation Manual Page 19
© Logic Energy Ltd. Registered in Scotland
B-2 Energy Meters & Solar Radiation Sensor
This example shows the configuration jumper settings and sensors for a typical Solar PV metering
installation, which monitors 2 energy meters (eg generation and export) and solar radiation.
The energy meters (electrical or heat) must be configured to provide a pulse output (dry contact, KYZ or
open-collector) of typically 1000 pulses per kWh depending on system size.
Sensors:
•Port D1 = Pulse output from generation energy meter (dry contact or open-collector)
•Port D2 = Linked to port D1
•Port D3 = Pulse output from export energy meter (dry contact or open-collector)
•Port D4 = Linked to port D3
•Port D7 = Solar Radiation sensor (Pyranometer)
As the digital ports A1-A4 are not used, they are configured in dry contact mode. Similarly the analogue
ports D8, D9 are not used, so they are configured as 0-5VDC mode.
