Chapter 1 Introduction
The OnCell G3100 series of cellular IP-modems have many exceptional features. There are
currently four models in the OnCell G3100 series of IP-modems: the OnCell G3110, OnCell G3150,
OnCell G3110-HSDPA, and OnCell G3150-HSDPA. The main differences between the models are
the serial interface types. Cellular IP-modems give you an easy way to connect your serial devices to
cellular mobile networks.
The following topics are covered in this chapter:

Overview
The OnCell G3100, which can be used to connect any serial device to a cellular network, supports a
number of different operation modes. The OnCell COM driver turns the OnCell G3100’s serial
ports into virtual COM ports that allow you to communicate with your serial devices remotely over
the cellular network. The OnCell G3100 comes pre-installed with the TCP/IP protocol suite to
transmit data back and forth between the serial device and GPRS/EDGE TCP/IP network.
The OnCell G3100 also supports Secure TCP Server, Secure TCP Client, Reverse Real COM, and
Secure Reverse Real COM modes for security critical applications, such as access control, and
remote site management.
The OnCell G3100 also comes with a built-in relay output that can be configured to indicate the
priority of events when notifying or warning engineers in the field, and the two digital inputs allow
you to connect basic I/O devices, such as sensors, to the cellular network.
For some applications, data must be delivered reliably even if communication is disrupted. The
OnCell G3100 provides a powerful function to ensure that data is buffered in case of a
communication failure. When a communication failure occurs, the data is buffered in the OnCell
G3100 until communication is resumed, at which point the buffered data is sent to its destination.
Package Checklist
Each OnCell G3100 serial cellular IP Modem is shipped in a separate box with standard
accessories. In addition, several optional accessories can be ordered separately. When you receive
your shipment, please check the contents of the box carefully, and notify your Moxa sales

Connecting the Hardware
This section describes how to connect the OnCell G3100 cellular IP-modem to a host PC or serial
devices for first time testing purposes. We cover Wiring Requirements, SIM Installation, 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 installing and/or wiring your device. The OnCell
G3100 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 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 consequently the casing may feel hot to the touch.
You should also heed the following guidelines:
yUse 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.
yUse 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.
yKeep input wiring and output wiring separate.
yWhere 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 G3100’s casing.
You will need to unscrew and remove the outer SIM card cover before installing or removing the
SIM card.
1
2
3
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 left 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
The SIGNAL 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 network is operating normally, then at least
one of the three SIGNAL LEDs should be illuminated at all times. If none of the 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 from over the network.

Connecting the Power
The dual power inputs that connect to the 4-pin power terminal block (2 terminals per power input)
can be used to connect the OnCell G3100 to a variety of field power sources that support 12 to 48
VDC. After connecting the power wire to the OnCell G3100’s terminal block, the “PWR” LED
will glow a solid green color to indicate that the system is ready.
Power Inputs
Connecting the I/O Port
Six terminals on the terminal block are reserved for the I/O ports, with 2 terminals used for each
input, and 2 terminals used for the output.
Digital Input
Digital ON and OFF determine which power input is used:DIN OFF: 0 to 3.3 VDC; DIN ON: 10
to 48 VDC (I1 to COM_1/I2 to COM_2)

Connecting to the Network
Connect one end of the Ethernet cable to the OnCell G3100's 10/100M Ethernet port and the other
end of the cable to the Ethernet network.
If the cable is properly connected, the OnCell G3100 will indicate a valid connection to the
Ethernet as follows:
yThe Ethernet LED glows a solid green when connected to a 100 Mbps Ethernet network.
yThe Ethernet LED glows a solid orange when connected to a 10 Mbps Ethernet network.
yThe Ethernet LED flashes when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
The OnCell G3110/G3110-HSDPA supports one RS-232 port that connects through a DB9 male
connector on the bottom panel.
The OnCell G3150/G3150-HSDPA supports one RS-232 port that connects through a DB9 male
connector on the bottom panel, and one RS-422/RS-485-4w/RS-485-2w that connects through a
5-pin terminal block on the bottom panel.
Adjustable Pull High/Low Resistors for the RS-485 Port (OnCell
G3150/OnCell G3150-HSDPA)
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 G3150/G3150-HSDPA uses DIP switches to set the pull
high/low resistor values for the serial port.
To set the termination resistor to 150 KΩ,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 KΩ, make sure both of the assigned DIP switches are in the
ON position.
ATTENTION
Do not use the 1 KΩsetting on the OnCell G3150/G3150-HSDPA when using the RS-232
interface. Doing so will degrade the RS-232 signals and shorten the maximum allowed
communication distance.
