Parameter scrolling: The default display mode is Auto Scroll Mode in which the parameters scroll

automatically. On pressing key, the meter display goes to manual mode. If key press doesn’t happen

for approximately 30 seconds, meter display returns to default mode i.e. Auto Scroll mode.

Push-to-push consumption: The push button is also used for measuring Push-to-Push kWh

consumption. Follow the below steps to measure the Push-to-Push kWh consumption:

a) Scroll through the parameters until Display No.11 (Refer Display Parameters Table 2) is displayed.

b) When Display No.11 is displayed; press and hold the push button, it resets to zero.

c) Energy recording starts in Display No.11.

d) Check Display No.12 to get the energy consumed value between the previous start-&-stop

operations.

WiFi Module DIN Energy Meter

Page 2 of 8

Wi-Fi is one of the most popular wireless communication standards on the market. WiFi

module is used to collect data from L&T make DIN meters through optical interface and to make it

available for the user through WiFi network. The module operates within the ISM 2.400 – 2.484 GHz

frequency band with IEEE802.11b baseband. This WiFi module is compatible with 1 Phase as well

3 Phase meters. The data can be viewed by the user through home page of the module using a web

browser as well as in the user application.

The modes for Wi-Fi connectivity are as follow:

- Infrastructure mode

- Ad hoc Mode

WiFi module is configured in Infrastructure mode as factory default.

Terminal cover to avoid direct contact of the supply terminals along with sealing

provision.


Supported network topologies: Ad-hoc and Infrastructure modes

IEEE 802.11b-compliant RF transceiver

Range: up to 100m

Supported connections: Open, WEP64, WEP128, WPA, and WPA2.

Mode key helps to configure the WiFi module to infrastructure or ad-hoc mode by pressing it for

1 second .If the same key is pressed for more than 10sec then the module will be configured to

factory defaults. Reset Key resets the module. Power ON LED gives the indication of the selected

mode. Ad-hoc mode will be indicated by the high pulse rate (i.e. 4 pulse/sec). Infrastructure mode

will be indicated by slow pulse rate (i.e. 3 pulses for 5 sec).

Infrastructure mode:

Infrastructure mode is one of the two methods of connecting the module to existing WiFi network

present at home or office with Wi-Fi enabled devices such as laptops, Smart phones etc. These

devices are connected to wireless network with the help of Access point (AP).

Setting Up Infrastructure Mode:

Power ON the meter and module. Configure WiFi router (or any smart device that support WiFi

hotspot) with SSID as “MiEnergyWiFi” and security as “Open”. WiFi module joins with the

configured router and can be accessed for installation.

Note the IP address (For eg: ‘192.168.0.103’) that will be displayed on DIN meter. Navigate to the

home page of the module using web browser by using the IP address as URL. Enter into

configuration page by clicking the link available in the home page using username “admin” and

password “lnt”. Select mode of communication as “Infrastructure” in configuration page and also

assign desired SSID to the module. Various types of security such as Open, WEP64, WEP128, WPA,

and WPA2 are supported. Select the desired security settings. Save these details and module will

restart with new settings.

Ad-hoc:

Ad-hoc is another mode of connectivity available in Wi-Fi. By using this mode, devices are capable

for communicating directly each other. All devices are connected in peer to peer communication

mode without using any Access point (router/switch) between devices. Note that android OS does

not support ad-hoc mode communication.

Setting up Ad hoc Mode:

Power ON the meter and module. Configure the module in Ad-Hoc mode by pressing the mode key

for more than 1 second. Connect device that supports Ad-hoc communication to the network SSID
