ESIM120 GPRS USER ManUal
3
1. operation description
Since July 2010 software supporting GRPS connection is installed in automatic gate controller ESIM120. The users will be able to
quickly perform configurations not only connecting the device to their computer but also remotely – using web browser.
GPRS connection is activated according to the standard GPRS parameters which are stored in device memory or according to one-
time GPRS parameters. These parameters are activated by sending the corresponding command via SMS message. One-time GPRS
parameters are valid only for one connection session (the system uses standard GPRS parameters with one or several indicated
changes). Standard GPRS parameters (Table 1) are changed by SMS messages, using special software or by connecting via web
browser.
One of the main GPRS parameters is the mode, i. e. Server or Client, which describes the way ESIM120 configuration web
environment is reached i. e. connecting directly to the device or through transitional server. In this case after activating Client
mode the administrator will be able to connect to the device through the internet website defined by the provider and the
connection will be maintained through the transitional server. After activating Server mode the administrator connects directly
to ESIM120 using web browser. However, this mode will operate only in the case GSM operator of the SIM card used in the device
provides a static IP address. It is also necessary to mention that GPRS connection is activated only for a particular period (session
time) and after this period is over it is ended automatically. In such a case, if the administrator wants to continue configuring
ESIM120 it is necessary to reactivate GPRS connection and to connect using the new login data.
Before activating GPRS connection, administrator must ensure the following conditions:
• ESIM120 is with a SIM card placed in it.
• Power supply is connected.
• The default 4-digit password is changed to a new one and your mobile number is uploaded as administrator mobile
number.
• The device isn't connected to computer with USB cable.
A short description of actions that should be taken in order to successfully use eSIM120 configuration web environment:
1. If requested, corrections are made in the standard GPRS parameters (refer to chapter 2.1 Configuring standard GPRS
Parameters);
2. The administrator sends SMS message with GPRS activation command from the mobile phone number registered in the
system (refer to chapter 2.3 GPRS Activation);
3. The system sends SMS message with login data (username and password) necessary for connecting to ESIM120
configuration web environment;
4. The administrator opens a corresponding web page (the address is formed depending on the running mode (refer to
chapter 3.1 Login to configuration webpge);
5. Configurations or other actions are made in ESIM120 configuration web environment (refer to chapter 3);
6. If session time is not ended after all the tasks are performed, end the connection by sending a corresponding SMS message
(refer to chapter 2.4 Additional Commands via SMS messages -> Ending the Session).
