Overview
OnCell G3111/G3151/G3211/G3251 gateways can be used to connect any serial device to a cellular network
and support a number of different operation modes. The OnCell COM driver turns the OnCell
G3111/G3151/G3211/G3251’s serial ports into virtual COM ports that allow you to communicate with your
serial device remotely over the cellular network. The OnCell G3111/G3151/G3211/G3251 comes pre-installed
with the TCP/IP protocol suite to transmit data back and forth between the serial device and GSM/GPRS
network.
For some applications, serial data must be delivered reliably even if communication is disrupted. The OnCell
G3111/G3151/G3211/G3251 provides a function to ensure that serial data is buffered in case of a
communication failure. When a communication failure occurs, the serial data is buffered in the OnCell
G3111/G3151/G3211/G3251 until communication is resumed, at which point the buffered data is sent to its
destination.

Connecting the Hardware
This section describes how to connect the OnCell G3111/G3151/G3211/G3251 cellular IP Gateway to a host PC
or serial device for first time testing purposes. We cover topics such as: Wiring Requirements, SIM Installation,
Wall and DIN-Rail Mounting, Connecting the Power, Connecting to a Serial Device, Adjustable Pull High/Low
Resistors for the RS-485 Port, and LED Indicators.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before install
ing and/or wiring your device. The OnCell
G3111/G3151/G3211/G3251 should be secured at one location.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes
dictating the maximum current allow
able 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
generat
e heat, and
consequently the casing may feel hot to the touch.
You should also heed 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. The
rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•Keep input wiring and output wiring separate.
•Where necessary, it is advisable to label the wiring to all devices in the system.

SIM Card Installation
In order to protect the SIM card, the SIM card slot is located inside the OnCell G3111/G3151/G3211/G3251’s
casing. You will need to unscrew and remove the outer SIM card cover before installing or removing the SIM
card.
Follow these steps to remove or install the SIM card:
1. Remove the screw holding the outer SIM card cover.
2. Push the outer SIM card cover to the down to remove it.
3. Rotate it upwards to expose the SIM card slot.
4. (a) Remove the SIM card from the SIM card slot, or
(b) Insert the SIM card into the SIM card slot.
5. Reverse the above steps to replace the outer SIM card cover.
ATTENTION
If the modem is in GSM/GPRS mode, SIGNAL LEDs will not be illuminated
if the phone number or APN is
incorrect. Check the GSM
/GPRS LED if the SIM card is installed correctly.
The
GSM/GPRS LEDs on the front panel provide a convenient way of checking if the SIM card is installed
properly. If the antenna is installed and the net
work is operating normally, then at least one of the three
SIGNAL LEDs should be illuminated at all times. If none of the GSM
/GPRS and SIGNAL
LEDs are illuminated,
then the SIM card may not be installed properly. This is because the PIN code is stored on the SIM card; if the
PIN code cannot be accessed, then the modem will not be accessible over the network.

OnCell G3000 Series Getting Started

DIN-Rail Mounting
The OnCell G3111/G3151/G3211/G3251 gateways have built
-in “ears” for attaching
the IP Gateway to a wall or the inside of a cabinet.
We suggest using two screws per ear
to attach the IP Gateway to a wall or the inside of a cabinet. The heads of the screws
should be less than 6.0 mm in diameter, and the shafts should be less than 3.5 mm in
diameter, as shown in the figure at the right.
Connecting the Power
Connect the 12 to 48 VDC power cord with the OnCell G3111/G3151/G3211/G3251’s power input. If the power
is properly supplied, the “PWR” LED will glow a solid green color to indicate that the system is ready.
Connecting to the Network
Connect one end of the Ethernet cable to the OnCell G3111/G3151/G3211/G3251’s 10/100M Ethernet port and
the other end of the cable to the Ethernet network.
If the cable is properly connected, the OnCell G3111/G3151/G3211/G3251 will indicate a valid connection to
the Ethernet as follows:
•The Ethernet LED glows a solid green when connected to a 100 Mbps Ethernet network.
•The Ethernet LED glows a solid orange when connected to a 10 Mbps Ethernet network.
•The Ethernet LED flashes when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
The OnCell G3111 and G3211 support one or two RS-232 port that connects through a DB9 male connector on
the bottom panel.
The OnCell G3151 and G3251 support one or two RS-232/RS-422/RS-485-4w/RS-485-2w port that connects
through a DB9 male connector on the bottom panel.

Adjustable Pull High/Low Resistors for the RS-485 Port
(G3151/G3251)
In some critical environments, you may need to add termination resistors to prevent the reflection of serial
signals. When using termination resistors, it is important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. Since a particular pull high/low resistor value cannot fit all environments, the
OnCell G3151/G3251 uses DIP switches to set the pull high/low resistor values for the serial port.
To set the termination resistor to 150 K
Ω
, make sure both of the assigned DIP switches are in the OFF
position. This is the default setting.
To set the termination resistor to 1 K
Ω
, make sure both of the assigned DIP switches are in the ON
position.
ATTENTION
Do
not use the 1 KΩsetting on the OnCell G3151/G3251 when using the RS-232 interface. Doing so will
degrade
the RS-232 signals and shorten the maximum allowed communication distance.
DIP switches on the bottom of the OnCell G3111/G3151/G3211/G3251 are used to set the pull high/low
resistor value for each serial port.
SW 1 2 3 4
Pull High Pull Low Terminator ---
ON 1 KΩ1 KΩ120 KΩ---
OFF 150 KΩ150 KΩ--- ---
Note: If the pull high/low resistor on your device is already set for RS-485, make sure the default
SW for RS-232 is “OFF” when you switch back to RS-232 interface.
LED Indicators
The LED indicators on the front panel of the OnCell G3111/G3151/G3211/G3251 are described in the following
table.
Type Color LED Function

Static and Dynamic IP Addresses
Determine whether your OnCell G3111/G3151/G3211/G3251 needs to use a static IP address or dynamic IP
address (either DHCP or BOOTP application).
•If your OnCell G3111/G3151/G3211/G3251 is used in a static IP environment, you must assign a
specific IP address using one of the tools described in this chapter.
•If your OnCell G3111/G3151/G3211/G3251 is used in a dynamic IP environment, the IP address
will be assigned automatically from over the network. In this case, set the IP configuration mode to DHCP
or BOOTP.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address for your
OnCell
G3111/G3151/G3211/G3251
in the MAC-
IP mapping table when using a DHCP Server or BOOTP Server. For
most applications, you should assign a fixed IP address to your
OnCell G3111/G3151/G3211/G3251.
Factory Default IP Address
The OnCell G3111/G3151/G3211/G3251 is configured with the following default private IP address:
192.168.127.254
Note that IP addresses that begin with “192.168” are referred to as private IP addresses. Devices configured
with a private IP address are not directly accessible from a public network. For example, you would not be able
to ping a device with a private IP address from an outside Internet connection. If your application requires
sending data over a public network, such as the Internet, your OnCell G3111/G3151/G3211/G3251 will need
a valid public IP address, which can be leased from a local ISP.

ARP
You may use the ARP (Address Resolution Protocol) command to set up an IP address for your OnCell
G3111/G3151/G3211/G3251. The ARP command tells your computer to associate the OnCell
G3111/G3151/G3211/G3251’s MAC address with an IP address. Afterwards, use Telnet to access the OnCell
G3111/G3151/G3211/G3251 and its IP address will be reconfigured.
ATTENTION
In order to use
the ARP setup method, both your compute
r and the OnCell G3111/G3151/G3211/G3251 must
be connected to the same LAN.
You may use an Ethernet cable to connect the OnCell
G3111/G3151/G3211/G3251
directly to your computer’s Ethernet card.
Before executing the ARP command,
y
our OnCell G3111/G3151/G3211/G3251 must be configured with the factory default IP address
(192.168.127.254) and your computer and the OnCell G3111/G3151/G3211/G3251
must be on the same
subnet.
To use ARP to configure the IP address, complete the following:
1. Obtain a valid IP address for your OnCell G3111/G3151/G3211/G3251 from your network administrator.
2. Obtain your OnCell G3111/G3151/G3211/G3251’s MAC address from the label on the bottom panel.
3. Execute the arp -s command from your computer’s MS-DOS prompt as follows:
arp -s <IP address> <MAC address>
For example,
C:\> arp -s 192.168.200.100 00-90-E8-04-00-11
4. Next, execute a special Telnet command by entering the following exactly:
telnet 192.168.200.100 6000
When you enter this command, a Connect failed message will appear, as shown below.
5. After the OnCell G3111/G3151/G3211/G3251 reboots, its IP address will be assigned to the new address
and you can reconnect using Telnet to verify that the update was successful.
