Mobile Data Configuration

Step 1a: To configure modem, select Messaging > Mobile Data Network. NOTE: Ensure that a modem has been selected per the previous step.

Step 1b: Mobile Data Network can also be accessed from the Project Navigator.

Step 2: On selecting Mobile Data Network, the following window will pop up:

Step 3a: Enable Mobile Data

When this option is checked the Modem gets connected to the service provider automatically. Mobile data is used to send GPRS data and Email through GPRS.

Step 3b: Manual Network Selection

In case selection of service provider needs to be done manually, Manual Network selection can be checked. The network provider name can be directly given in Name field or the same can be provided through a register / Variable reference as well. To provide register/variable reference for service Provider, check Get Service Provider Name from Register and enter the register/variable reference in Address. In this case, the preferred service provider name string with null termination Null Termination - To place a NULL character (character code 0) at the end of ASCII data. Some functions require NULL Termination to be able to determine the end point of the ASCII data since that data may vary in length from one time to the next. needs to be provided at the specified register / Variable.

Step 4: Signal Strength Register

Configure a register address to store Signal strength. The signal strength values and description are as follows:

Register Value (Decimal)	Signal Strength	Description
99		Not Known or Not detectable
0	-113 or less	Marginal
1	-111	Marginal
2	-109	Marginal

14	-85	OK
15	-83	Good
16	-81	Good
17	-79	Good
18	-77	Good
19	-75	Good
20	-73	Excellent
21	-71	Excellent
22	-69	Excellent
23	-67	Excellent
24	-65	Excellent
25	-63	Excellent
26	-61	Excellent
27	-59	Excellent
28	-57	Excellent
29	-55	Excellent
30	-53	Excellent
31	-51 dBm or greater	Excellent

Step 5: Network Status Register

Network Status Register uses block of 60 consecutive register to indicate the status of the Network. The details of status registers for 2.5G/ 3G modems are as follows: Network status register+0: 16bits

Bit 1	TRUE if basic modem initialization is done
Bit 2	TRUE if context activation for data connection is done
Bit 3	Reserved
Bit 4	TRUE if Manual registration is done
Bit 5	TRUE if Modem initialization is going on
Bit 6-8	Unused
Bit 9	TRUE if Modem communication is not working
Bit 10	TRUE SIM PIN command fails
Bit 11	TRUE if registration failed
Bit 12	Reserved
Bit 13	Unused
Bit 14	Unused
Bit 15	Reserved
Bit 16	Unused

Network status register + 1	32bit	Network allocated IPV4 in binary
Network status register + 3	16 Bytes	IMEI Number of Modem
Network status register + 11	16 Bytes	Reserved
Network status register + 19	16 Bytes	Reserved
Network status register + 27	2 Bytes	Modem initialization count
Network status register + 28	2 Bytes	Modem initialization success count
Network status register + 29	2 Bytes	Modem context activation success count
Network status register + 30	(80 x 6) Bits	Individual Socket status (6 registers currently 3 in use) Socket 1 - Modem Block Socket 2 - Cscape Socket 3 - Email Socket 4 to 6 - Reserved

Network status register + 30: (80 x 6) Bits

Bit 1	Connection_type	TCP-0 or UDP-1
Bit 2	Connection_dial	TRUE if socket is dial, else Listen
Bit 3	Connection_open	TRUE if open, 0 for close
Bit 4	Conn_lsn_err	TRUE if Listen mode or connecting to client fails
Bit 5	Conn_acpt_err	TRUE if accepting connection fails
Bit 6	Conn_send_err	TRUE if data send fails
Bit 7	Conn_recv_err	TRUE if data receive fails
Bit 8	Sock_buf_over	Buffer overflow error
Bit 9 to 16	Connection_status	Contains different modem status 0 - Socket is Free 1 - Socket is requested 2 - Socket connection is establishing. 3 - Socket is closed. 4 - Socket is listening. 5 - Socket with an incoming connection request. 6 - Socket with an active data transfer connection. 7 - Socket is suspended 8 - Socket is suspended with pending data
Bits 17 to 48		Total data sent (In bytes)
Bits 49 to 80		Total data received (In bytes)

Debug Logging Register – This Register/Variable is used to enable debug log and log file will be created in microSD card .THIS REGISTER MUST BE TURNED ON ONLY IF THERE ARE ANY ISSUES WITH MODEM FUNCTIONALITIES. For normal operations the register/variable value must be turned OFF. NOTE: Turning ON Debug Logging register/variable will have an impact on scan rate.

SMS COM Port Configuration

In the Mobile Data configuration dialog, selecting SMS COM Port Configuration pops up the following window:

The following selections must match the default settings of the modem that is being used:

Port - Select the desired port. The number of ports vary depending on the controller used

Mode - Select connection mode. The drop-down list changes according to the port selection

Comm Settings - Select Baud Rate, Parity, Data Bits, Stop Bits and Handshake Handshaking is an automated process that sets parameters for communication between two different devices before normal communication begins. Much like the way a human handshake sets the stage for the communication to follow, the computing handshake provides both devices with the basic rules for the way data is to be shared between them. These rules can include transfer rate, coding alphabet, parity, and interrupt procedure. settings as per the default settings of the modem that is being used.

Port configuration for HE-XRC2Q (2.5G) and HE-XRC3D (3G) Modems should be as below:

NOTE: Select Port as COM or MJ1/COM based on controller type. In XLE/XLT/XLEe/XLTe controllers HE-XRC3D/HE-XRC2Q modem utilizes the same internal communications channel (UART) as the MJ1 serial port; thus, enabling the modem deactivates the MJ1 serial port. However, support is provided to select which device (or port) is currently active. XL4, EXL6, EXLW, XL7 & EXL10 provide a COM port to support the modem thereby leaving MJ1 free for other use.

Modem Initialization

Selecting Modem Initialization pops up the following window:

Configuration of Initialization Status Register Settings and User Specific Modem Initialization Script in the above screen is required when User Initialization Script is selected

Modem Initialization Settings
Modem Initialization Type	The following options are available: No Initialization (Modem Preconfigured): No initialization of GSM modem will be done. Select this option if connected GSM modem is preconfigured and does not require initialization. Internal Modem Initialization: Select this option if an XL series controller is connected with internal modem. Siemens TC Modem Initialization: In case of external GSM modem, select this option. User Initialization Script: To use own initialization script, select User Initialization Script. When User Initialization Script is selected, it is necessary to configure initialization status register and provide initialization script. The type of Modem Initialization used affects various settings that are available on the COM Port screen.
Address	Enter the starting register address location used to store the additional modem initialization script’s latest command executed. This is a block of 10 registers that are consecutive in memory. For example, if the users are using R301 - R310, then the users need to enter the starting register address as %R301.
Name	Enter (or select) the I/O Name.
User Specific Modem Initialization Script	Enter script in this box.
