# 6. GPRS settings

NOTE: before starting the configuration of the device you must press the button CONNECT VIA USB or READ SETTINGS. If these actions are not completed your parameters can be lost and you might need to restore factory default settings. NOTE: to enable the changes in the device you must press the button WRITE SETTINGS.

Using GPRS connection the administrator can access gate controller ESIM120 via Internet browser as well. Thus the administrator can remotely perform configurations as well as review all the textual information about gate operation – when and what user activated the gate etc. – stored in device register.
In Configuration Tool program environment GPRS settings can be modified in GPRS section.

# 6.1. Operation Mode Selection

Client – gate controller ESIM120 is accessible via Internet browser through the server.
Server – the device will operate in server mode, i. e., it will be accessible directly through internet browser without the usage of any other additional programs. GSM operator has to provide a static external IP address to the SIM card used in the device.

Attention: only one user can connect to the device via Internet browser at a time.

# 6.2. Identification Settings

| Profile – name of the selected GPRS parameters. The initial name provided by the manufacturer is profile1. It is used when sending SMS message with the command connect to use your selected standart GPRS connection. APN – GPRS access point provided by the GSM operator of the used SIM card. User Name – user name (provided by GSM operator). Password – password (provided by GSM operator).

# 6.3. TCP/IP settings

| Server IP – Remote server IP address or domain. It is recommended not to change default paramater. Server TCP Port – Remote server parameter. It is recommended not to change default paramater. DNS1 – Top-level DNS Server IP address. It is recommended not to change default paramater. DNS2 – DNS Server IP address. It is recommended not to change default paramater. Local TCP Port – Computer TCP port used for communication with the device.

Session Time – Time of one session; when this period expires the administrator has to reconnect with new login data. By default this period is 20 minutes. Attention: when the indicated session time is “0“, connection session will continue until the administrator terminates it by sending a particular SMS message (see more GPRS User Manual).

Attention: to put the device in Client mode it is necessary to enter Server IP and Server TCP Port data. Attention: to put the device in Server mode it is necessary to enter Local TCP Port data.

| It is also necessary to select the method data is delivered to users: using TCP ( Transmission Control Protocol) or UDP (User Datagram Protocol) protocol.
Attention: currently the device supports TCP protocol only.

# 6.4. Additional Settings

| GPRS Control settings group is used for selecting the administrators that will receive connection data calling on the telephone number of the SIM card (otherwise it is necessary to send SMS message with the connection command).
Attention: when these settings are activated the selected administrators will not be able to control output (relay) contacts via call. Besides, a repeated call during the session works the same way as sending SMS message for restoring GPRS connection (when the connection is interrupted).
Log Full SMS Enable - activate this setting if you want the administrator to receive SMS message about a completed ESIM120 operation summary file (SMS messages will be delivered in the order starting with administrator User1 and ending with User5 , until the first successful message delivery). In this case it is necessary to empty this file, i. e. to connect to the device via Internet browser and select a corresponding item (see more on GPRS User Manual). Maximum file size of this summary is 44KB (1000 entries about the use of gate controller). New entries are not entered until this file is emptied.
