6. INTRODUCTION
Many times a need is felt to upgrade software of a remotely situated device/machine, or
monitor its parameters, or receive warnings on malfunctioning to a remotely situated server. Taking
advantage of the large mobile networks and their supporting GPRS features, it is now possible to
connect devices in the field back to a central server simply and cost-effectively. Using wireless cellular
technology, serial devices such as PLC, Modbus, RFID scanners, data loggers, electricity meters,
pumps, valves, POS (Point-Of-Sales) terminals and such other equipments can be connected to a
central processing server without the requirement for cables to be installed. All you need is a device
which has a serial port, and WirelessCom/G10. Just configure and connect WirelessCom/G10 to your
device/machine and your device/machine would easily turn it into a device which can be accessed from
any remotely located server.
WirelessCOM/G10 is exactly what its name says; it is a wireless COM port. When
WirelessCOM/G10 is connected to any equipment with COM/RS-232 ports, it just replaces the
physical cable (RS232) connection by wireless GSM network. This means, the length of RS232 cable
would be as long as a GSM network. Thus, as far as a GSM network is available, this device will be
accessible from any part of the world. In simple words, WirelessCom acts as a bridge between serial
port and GPRS. All the information coming through GPRS/CSD is sent to serial port and all the
information coming on serial port is sent to GPRS/CSD. In short there is a transparent connection
between WirelessCom and the server/PC (for example) without any physical limits.
WirelessCom is basically an intelligent pre-programmed modem for making GPRS/CSD
connections and handle the exceptions arising during the process of making connection. Thus you
don’t need an external microcontroller to control WirelessCom using AT commands. All you need is to
configure WirelessCom (the configuration parameters are explained in later sections) and it will
automatically make connections using the configured bearer (GPRS/CSD). If anything goes wrong, for
example GPRS activation failed/CSD call could not be established/GPRS connection could not be

established/CSD call was not answered, you would receive SMS indicating the errors and the
concerned parameters.
Once configured, connect (physically) WirelessCom to the serial port of your remote
device/machine and you would be able to access your device remotely through GPRS/CSD.
Additionally, if you want to change the configuration parameters of WirelessCom you can do it
remotely using GPRS/CSD/SMS.
The next section would explain 2 scenarios 1) Typical wired connection which is being
used by most of the users. 2) A solution which would turn your wired connection into a wireless
solution so that you would have remote access, control and monitoring of your device/machine
through GPRS/CSD.
6.1 Wired Solution
A typical wired setup includes a device/machine with a RS232 port connected to the
serial port of the PC using a normal RS232 cable, refer fig 6.1. The user then launches some proprietary
software which came with the device/machine (or it can be a terminal software) and connects the
software to the same serial port to which device/machine is connected, refer fig 6.1 (b). Thus a
connection between device/machine and the software has been established. Now the user can
configure, operate, collect data, program the device/machine and perform such various operations. In
short the user is in total control of the device/machine.

6.2 Wireless solution using WirelessCom/G10
A typical setup may look as shown in figure 6.2, WirelessCom may be connected
(physically) to any device, machine (which has a RS232 port) located in a remote place and the server
computer would be present at the company/home. Through various parameters settings (server ip,
server port, apn……) present in WirelessCom, it would be configured to connect to the server.
On the server would be running two software’s,
a) TCP-to-Serial software/Telnet/TCP port software:TCP-to-serial software is only required if
you have dedicated (proprietary) software which you use to control/configure/read/write your device.
This software is used to create a virtual serial port on your computer. This port will appear as a
hardware port for your computer. The main function of this software is to direct all the data coming on
the TCP port to the virtually created serial port.
If you are using simple terminal software for interacting with your device, in that case you
can use any Telnet software* (Microsoft Telnet) or a TCP port communication software like Netcat
and set a TCP/IP port in listening mode.
*Refer to APPENDIX II for more details
b) Proprietary software:This software (can be even a free terminal software) is used to make
a connection from PC to the device/ machine using normal serial port (as explained in the scenario of
wired solution). Launch this software and connect it to the virtually created serial port. The setup is
done and your proprietary software is now connected to your device/machine remotely through GPRS.

The setup for configuration is ready now, however if you want to see the characters which you are
typing on hyper terminal, proceed to next steps,
5. In the File menu choose Properties and Settings. In the opened window choose ASCII
Setup.
6. Switch on (see Figure 7.2.2):
ªSend line ends with line feeds.
ªEcho typed characters locally.
Figure 7.2: ASCII Setup window
Click OK.
7.3 Entering into configuration mode
1. Click the button Call on Hyper Terminal toolbar.
2. Power-up WirelessCom/G10 from the AC/DC adapter.
3. When the status LED starts to blink green (device initialization) press and hold spacebar on the
Hyper Terminal window, until a message: “Welcome to WirelessCOM/G10 Configuration
console. Firmware version: xx.xx.xx” appears. LED will blink green and yellow alternately to
indicate configuration mode.
* Once WirelessCom/G10 is powered-up, for the initial 8 seconds it is waiting to see if user
wants to enter into configuration mode or not. Once these 8 seconds are elapsed you cannot
enter configuration mode, you would need to restart the device.
7.4 Command set
Now you can use the commands for a full configuration of the device. To see all the
available commands enter help command in configuration console and you will get a list of commands
with their short description. The commands are described in brief below,
1) get:This command will give you the information about configuration parameters
of WirelessCom/G10. If you need information about all the parameters, just type get
and press enter/return key. To get the information about individual configuration
parameter, type get xxxx where xxxx is the name of configuration parameter, and

13
13
press enter/return key.. For example, get mode this command will give you the
information about the mode in which WirelessCom/G10 is configured.
2) set: This command performs 2 functions,
a) It gives you the information about all the configuration parameters and their valid
values. To get this info, just type set and press enter/return key.
b) This command is also used to enter the values of configuration parameters. Type
set xxxx yyyy and press enter/return key, where xxxx is the configuration parameter
name and yyyy is the value of configuration parameter. For example set bearer gprs
this command will choose the bearer type as gprs.
3) test: Once you have configured all the necessary parameters, you can use this
command to check if the settings are fine and if WirelessCOM/G10 is able to make
connections using GPRS/CSD bearer. If test is used for CSD bearer,
WirelessCOM/G10 will try to connect to the number configured in csd_phone.
Therefore make sure that the phone number is correct and ensure that csd_phone will
answer the call from WirelessCOM/G10. If test is used with GPRS bearer in master
mode, then WirelessCOM/G10 will try to activate gprs and connect to the configured
ip address and port. When the GPRS connection with server is established
WirelessCom/G10 will make a small data transfer (all the information about
configuration parameters) and then close the connection.
4) clear:This command is used to clear the values of string parameters. These
parameters include username, userpassword, device_id, password, apn, auth_phone1,
auth_phone2, auth_phone3, auth_phone4, csd_phone. To clear a particular value, type
clear xxxx where xxxx is the name of configuration parameter, and press enter/return
key, for example clear username You can clear all the string parameters and some
numerical parameters in one time by typing clear all If you will type only clear and
press enter/return key, it will show you the parameters which can be cleared by using
this command.
5) restart:This command is used to restart WirelessCOM/G10. Type restart and
press enter/return key.
6) pin:If you have a sim card with enabled pin, WirelessCOM/G10 gives you the
possibility to enter the pin (of sim card) automatically each time the device restarts.

14
14
Using this command, WirelessCOM/G10 will store the pin in its memory and
whenever the device restarts WirelessCOM/G10 will enter the pin automatically. To
save a pin type pin xxxx where xxxx is the pin of your sim card, and press
enter/return key.
7) puk:If you have a sim card with enabled puk, WirelessCOM/G10 gives you the
possibility to enter the puk (of sim card) automatically each time the device restarts.
Using this command, WirelessCOM/G10 will store the puk in its memory and
whenever the device restarts WirelessCOM/G10 will enter the puk automatically. To
save a puk type puk xxxx where xxxx is the puk of your sim card, and press
enter/return key.
In addition to the above commands, there are commands for preset connection
profiles of GPRS and CSD connections. Using these commands you can set the
configuration settings for a particular bearer and mode to typical values. They are as
explained below,
8) gprs_master:This command will set WirelessCOM/G10 to gprs master mode
configuration with typical values (factory configured). Just type gprs_master and press
enter/return key.
9) gprs_slave:This command will set WirelessCOM/G10 to gprs slave mode
configuration with typical values (factory configured). Just type gprs_slave and press
enter/return key.
10) csd_master:This command will set WirelessCOM/G10 to csd master mode
configuration with typical values (factory configured). Just type csd_master and press
enter/return key.
11) csd_slave:This command will set WirelessCOM/G10 to csd slave mode
configuration with typical values (factory configured). Just type csd_slave and press
enter/return key.
* Whenever you have configured WirelessCom/G10, before restarting the device use the test
command. The command will test WirelessCom/G10 with your current configuration settings and
check if connection is possible or not. However if you had made changes to mode, bearer or
bearer_retry_timeout, you would need to restart the modem and then use the test command

will connect to the server at the
configured time. In clock-based approach,
time can be entered in terms of clock
hours (for this feature it is necessary to
configure the clock parameter) for
example, 15:30 this means everyday
WirelessCom/G10 will automatically
connect to the server at 15:30. In time-
based approach, time can be entered in
minutes (clock parameter does not need to
be configured) for example, 200 this
means WirelessCom/G10 will connect to
the server after every 200 minutes.
Table 7.1: WirelessCOM/G10 general configuration settings
* pin,puk,password are not displayed in the normal configuration menu (the menu which appears
when you type get and press enter). Instead you have to access them individually by typing get xxxx,
where xxxx is the name of configuration parameter.
** Autoconnect feature is only available for GPRS bearer in master mode. The feature is disabled
when WirelessCom/G10 is in configuration mode
*** If you are making CSD call to WirlessCom/G10, make sure that you are not hiding your caller
id. If not WirlessCom/G10 will not be able to recognize the incoming caller id and would reject the
call.

An SMS can include single parameter or multiple parameters. When multiple parameters are to be
configured separate them with spaces. You don’t need to include “set” after every parameter. Just type
the parameters you want to configure along with their corresponding values and end the message with
“set”. e.g: ip 222.222.222.222 port 1234 apn web.gsm mode slave auth_phone1 [phone] set
* It is very important that you type the SMS in lowercase, if not SMS configuration will fail. Also
each sms should end with set (except get1,get2 and restart), if not, only the parameters before set
would be configured, anything after set will be discarded.
** If you make a mistake (in format of sms or values of parameters) while sending sms, you will
receive a sms which would include errors.
***restart command will only be executed if there were no errors during configuration through
sms. We recommend you to restart WirlessCom/G10 after you have finished the configuration
(mode and bearer would only be changed after restart).
