Connecting the Hardware
This section describes how to connect the OnCell G2111/G2151I Series modem to a host PC or serial devices
for initial testing and configuration.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings,
the wiring could overheat, causing serious damage to your equipment.
Temperature Caution!
Be careful when handling the device. When plugged in, the device’s internal components generate heat and the
casing may feel hot to the touch.
You should also pay attention to the following guidelines:
•
Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•
Use the type of signal transmitted through a wire to determine which wires should be kept separate.
Generally, if different wires share similar electrical characteristics, they can be bundled together.
•
Keep input wiring and output wiring separate.
•
If possible, it is recommended that all device wiring be clearly labeled.

AT Command Set
AT Command Set Introduction
The OnCell G2111/G2151I Series modem supports the V.25ter AT command set. The “AT” prefix (also known
as the Attention Code) signals the modem that one or more commands are to follow. The AT command set is
an industry-standard language that is used to communicate with modems. The OnCell G2111/G2151I Series
modem is always either in command mode or in on-line mode. When first powered up, the modem will enter
command mode. The modem will only accept commands when it is in command mode. Commands that are
received when the modem is in on-line mode are treated as data, not as commands. Commands may be
entered from terminal software such as Windows HyperTerminal, or Moxa PComm Lite Terminal Emulator.
Settings made with AT commands are automatically reused by the modem until another command is received
to change the settings, or the modem is turned off.
All but two of the commands must begin with the characters AT. The two exceptions are the escape sequence
(+++), and the repeat command (A/). The command line prefix (letters AT) and the command sequences that
follow can be entered in upper case or lower case, but the cases must not be mixed. More than one command
can be typed on one line, and commands can be separated by spaces to make them easier to read. The
spaces are ignored by the modem’s command interpreter. The command line buffer accepts up to 39
characters including, “A” and “T”. Spaces, carriage returns, and line feed characters are not placed in the buffer
and do not count towards the 39-character limit. If more than 39 characters are entered, or if a syntax error is
encountered in the command sequence, the modem returns an ERROR result code, and the command input
is ignored.
The modem will acknowledge most commands almost immediately. As soon as you type in a command ending
with the carriage return character, your modem will respond with OK.
ATTENTION
+++
This is one of the two commands that do not use the AT prefix. The 3 “plus” signs are used for the Escape
Character Sequence. After you have connected to another modem, you may need to return to command mode
to modify the modem’s configuration or to hang up. To do this, leave your keyboard idle (do not press any
keys) for at least one second, and then press “+” three times. You do not need to press the Enter key. After a
moment, the modem will respond with OK, indicating that Command mode is now active.
Starting Moxa Terminal Emulator
The following instructions explain how to install the Moxa PComm Lite Package. After installing PComm Lite,
you can use the built-in Moxa Terminal Emulator to handle your modem operations.
ATTENTION
OnCell Terminal Emulator is designed for Windows 2000, XP, 2003, and Vista. If you are running Windows 98,
ME, or NT, use PComm Lite V2.6, which can be downloaded on the Moxa website.
1. Start Terminal Emulator from the Windows Start menu.
2. The PComm Terminal Emulator user interface will appear. Click the Open button, which is the first blue icon
on the tool bar.

3. Select the target COM port and communication parameters. Click OK to open the port.
4. Terminal Emulator will connect to the target COM port.
AT Command Examples
The following examples can give users a better understanding of how to use the AT Commands.
ATTENTION
Make sure that the RS-232 port of the OnCell G2111/G2151I Series modem is connected. For the OnCell
G2151I, make sure DIP switch 1 is set to ON.
Modem Acknowledgement
Connect the RS-232 port of the OnCell G2111/G2151I Series modem to a host PC. Start PComm Terminal
Emulator with the current communication parameters (default: 115200 bps, 8 data bits, None parity, 1 stop

bits, and no flow control). Type AT and press Enter. A modem response of OK indicates that the modem is
ready.
Verify Signal Strength
Connect the RS-232 port of the OnCell G2111/G2151I Series modem to a host PC. Open PComm Terminal
Emulator with the current communication parameters (default: 115200 bps, 8 data bits, None parity, 1 stop
bits, and no flow control). Type AT+CSQ and press Enter. The modem will respond with the receive signal
strength (RSSI) and channel bit error rate (BER).
Signal Strength Verification
0 to 12
Weak or insufficient
13 to 19
Average
20 to 31
Exceptional
99
No signal
BER ranges from 0 to 7, with 7 corresponding to a higher error rate.
ATTENTION
RSSI should be higher than 12 if you wish to create or accept GSM/CSD data calls or establish a GPRS
connection. If the RSSI is less than 12, you will only be able to transmit and receive SMS (short message).
To check the bit error rate there must be a call in progress to obtain realistic values. If no call is set up, there
is no BER to be determined. In this case the indicated value may be 0 or 99, depending on the SIM card.
PIN Code Management
Operation of the OnCell G2111/G2151I Series modem requires the installation of an active SIM (Subscriber
Identity Module) card. The SIM card contains the necessary data to identify the modem to the network service
provider. It is also used to store the GSM/GPRS modem PIN (Personal Identification Number.) and PUK
(Personal Unblocking Key), which are also used with mobile phones. The PIN helps prevent unauthorized

persons from using the mobile devices. Users must enter the PIN each time the modem is powered up. The PUK
is used to unlock a SIM card when an incorrect PIN code has been entered three times.
Query the Current PIN Status
Connect the RS-232 port of the OnCell G2111/G2151I Series modem to a host PC. Start PComm Terminal
Emulator with the current communication parameters (default: 115200 bps, 8 data bits, None parity, 1 stop bit,
and no flow control.)
1. Type AT+CPIN? and press Enter.
If the OnCell G2111/G2151I Series modem responds with “+CPIN: SIM PIN” then the user must enter the
SIM’s PIN code.

Be careful when entering the PIN codes.
After 3 unsuccessful attempts at entering the PIN, you will need to use the PUK to proceed. PUK validation
forces the user to enter a new PIN code as a second parameter, and this will be the new PIN code if PUK
validation succeeds. CHV1 will be enabled if PUK1 is correct. Therefore, the application uses the following
command:
AT+CPIN=<PUK>,<NewPIN>
Note that users must apply for PUK codes from the mobile service provider.

GSM/CSD Connection
A Circuit-Switched Data Connection makes the wireless modem work in a manner similar to a regular analog
modem. You must have CSD service in order to make a CSD call.
The following topics are covered in this chapter:
 Overview
 Initiating a CSD Connection
 Answering a CSD Connection
OnCell G2111/G2151I Series
GSM/CSD Connection
Overview
CSD (Circuit Switched Data) is the original form of data transmission developed for GSM systems. By using a
single radio time slot, CSD is able to deliver 9.6 to 14.4 kbit/s data transmission to both the GSM network and
PSTN switching subsystem through direct calls. Most of the time, it is initiated by standard AT commands. Using
the modem to access remote devices by CSD is often more convenient than installing cables and data lines.
Data collection and monitoring will be more flexible since CSD can be used for applications that are hard to wire
or hard to access.
Initiating a CSD Connection
A CSD connection can be initiated using the OnCell G2101 Series modem and PComm Terminal Emulator.
1. Start PComm Terminal Emulator with the current communication parameters.
ATTENTION
Use the AT command AT+CSQ to check the current signal strength value (refer to the OnCell G2101 AT
command list in section 8.5).
If no signal is detected (RSSI return value = 99), then the SIM card is not installed properly, or there is no
signal present. If the signal strength is not strong enough to create a CSD connection (RSSI return value < 12),
adjust the position of the antenna, change the location of the modem, or use an optional high-gain antenna.
Verify that your SIM card has CSD service activated. For most regions, you must apply with your mobile service
provider to receive this service.
Verify that the RS-232 port on the OnCell G2111/G2151I Series modem is connected. For the OnCell G2151I,
verify that DIP switch 1 is set to ON.
2. Type ATD <phone number> and press Enter. For example, type ATD 0289191230 if the phone number
is 0289191230.
3. Check the STATUS indicator on the front panel of the modem. If the LED is steadily on, the CSD connection
has been established successfully.
4. To close the CSD connection, type +++. The modem will respond with OK to indicate that you have already
switched back to the command mode.
4-2
OnCell G2111/G2151I Series
GSM/CSD Connection
5. Type ATH and press Enter to disconnect.
ATTENTION
+++ is the escape sequence, and ATH is the hang-up command.
For international calls, the local international prefix does not required, but the + character is. You would type
ATD+886289191230.
Answering a CSD Connection
PComm Terminal Emulator can be used to answer a CSD call manually:
1. When the terminal displays “RING”, type ATA and press Enter.
2. Check the STATUS indicator on the front panel. If the LED is steadily on, the CSD connection has been
established successfully. The modem will automatically switch to data mode. At this point, you can proceed
with data communication.
3. PComm Terminal Emulator can be used to configure the modem to answer CSD calls automatically:
4. In the terminal window, type ATS0=x and press Enter. For x, substitute the number of rings that the
modem should receive before answering the call. For example, to answer after the first ring, type ATS0=1.
5. Type AT&W and press Enter.
4-3
OnCell G2111/G2151I Series
GSM/CSD Connection
6. To disconnect the modem, type +++. The modem will respond with OK, which means that you have
already switched back to command mode. Type ATH and press Enter to disconnect.
ATTENTION
If you are answering a call from a PSTN dial-up modem, type AT+CICB=0 to force the incoming call to be a data
call. Type AT+CBST=7, 0, 1 to select bearer type to V.32 modem (9600 bps). In addition, type AT&W to save
the settings. For further information, please refer to the OnCell G2111/G2151I Series AT Commands Guide on

GPRS Connection
OnCell G2111/G2151I Series
GPRS Connection
GPRS Overview
GPRS is a packet-switched technology, which means that multiple users share the same transmission channel.
In addition, transmission only occurs when there is outgoing data. This means that the available bandwidth can
be dedicated solely to data communication as needed. In general, a GPRS network can be viewed as a special IP
network that offers IP connectivity to IP terminals. Devices such as PCs, embedded computers, and PLCs that are
PPP-enabled can be easily connected to the IP network and the Internet.
The OnCell G2111/G2151I Series modem is a multi-slot Class 10 device, which means that there are 4 Rx
timeslots plus 1 Tx timeslot, or 3 Rx timeslots plus 1 Tx timeslot. This requires that the provider support CS-1
to CS-4 coding schemes. GPRS offers no guaranteed data rates or bandwidth. The value assigned by the
provider (coding scheme and timeslots) can change dynamically during a connection.
In general, for the 1 Tx + 4 Rx combination, the Tx throughput is around 8 to 12 Kbps and the Rx throughput
is around 32 to 48 Kbps.
For the 2 Tx + 3 Rx combination, the Tx throughput is around 8 to 12 Kbps and the Rx throughput is around
32 to 48 Kbps.
Windows GPRS Access
The OnCell G2111/G2151I Series modem can use Windows DUN (Dial-up Networking) to provide Internet
access through the GPRS mobile network. The following pages explain how to configure the modem and your

indicators are dark, then the SIM card is not installed properly, or the modem is not picking up a signal. If only
one bar lights up, the signal is not strong enough for a GPRS connection. Adjust the position of the antenna,
change the location of the installation, or use an optional high-gain antenna instead.
Make sure that your SIM card account supports GPRS service. In most regions, you will need to apply with your
mobile service provider to activate the service.
Make sure that the RS-232 port of the OnCell G2111/G2151I Series modem is connected. For the OnCell
