Connecting the Hardware

This section describes how to connect the OnCell G3111/G3151-HSPA cellular IP gateway to a host PC or serial
device for the first time. We cover topics such as: Wiring Requirements, SIM Installation, Wall and DIN-Rail
Mounting, Connecting the Power, Connecting to the Ethernet, Connecting to a Serial Device, Adjustable Pull
High/Low Resistors for the RS-485 Port, and LED Indicators.

Wiring Requirements

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.

Connecting to the Ethernet

Connect one end of the Ethernet cable to the OnCell G3111/G3151-HSPA’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-HSPA 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-HSPA supports one RS-232 port that connects through a DB9 male connector on the bottom
panel.

The OnCell G3151-HSPA supports one 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-HSPA)

In long distance transmission or 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-HSPA 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.

configured with the correct time server address, it will request time information from the time server every 10

minutes.

Network Settings

Basic Network Settings

You can access Basic Network Settings by expanding the Network Settings item in the navigation panel.

Basic Network Settings is where you assign the OnCell G3111/G3151-HSPA’s IP address, netmask, gateway,
and other parameters for the Ethernet interface.

Note: You must assign a valid IP address to your OnCell G3111/G3151-HSPA before it will work in your
network environment. Your network system administrator should provide you with a unique IP address and
related settings for your network. First-time users can refer to Chapter 3, Initial IP Address Configuration
for more information.

IP Address (default=192.168.127.254): Enter the IP address that will be assigned to your OnCell

G3111/G3151-HSPA. All ports on the OnCell G3111/G3151-HSPA will share this IP address. An IP address is a
number assigned to a network device (such as a computer) as a permanent address on the network.
Computers use the IP address to identify and talk to each other over the network. Choose a proper IP address
that is unique and valid for your network environment.

Netmask (default=255.255.255.0): Enter the subnet mask. A subnet mask represents all of the network hosts
at one geographic location, in one building, or on the same local area network. When a packet is sent out over

the network, the OnCell G3111/G3151-HSPA will use the subnet mask to check whether the desired TCP/IP
host specified in the packet is on the local network segment. If the address is on the same network segment as
the OnCell G3111/G3151-HSPA, a connection is established directly from the OnCell G3111/G3151-HSPA.
Otherwise, the connection is established through the given default gateway.

Gateway: Enter the IP address of the gateway if applicable. A gateway is a network computer that acts as an
entrance to another network. Usually, the computers that control traffic within the network or at the local
Internet service provider are gateway nodes. The OnCell G3111/G3151-HSPA needs to know the IP address of
the default gateway computer in order to communicate with the hosts outside the local network environment.
For correct gateway IP address information, consult the network administrator.

after 3 seconds, and the third after 5 seconds.

WINS function (default=enable): Enable or disable the WINS (Windows Internet Naming Service) server.

WINS server: If a WINS Server is connected to the network, enter the WINS Server’s IP address in this field.

TCP/IP uses IP addresses to identify hosts, but users often use symbolic names, such as computer names. The
WINS Server, which uses NetBIOS over TCP/IP, contains a dynamic database to map computer names to IP
addresses.

LAN speed (default=Auto): You may configure the network speed for the built-in Ethernet connection on the
OnCell G3111/G3151-HSPA. IEEE802.3 Ethernet supports auto negotiation of transfer speed. However, some
switches/hubs require that the communication speed be fixed at 100 Mbps or 10 Mbps.

DHCP (default=Enable): DHCP stands for Dynamic Host Control Protocol. When you enable the DHCP Server,
it will automatically assign an IP address to the computers on the LAN or private network. Be sure to set
your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.”
When you turn your computers on, they will automatically load the proper TCP/IP settings provided by the
OnCell 5000. The DHCP Server will automatically allocate an unused IP address from the IP address pool to
the requesting computer. You must specify the starting and ending address of the IP address pool.

DNS relay (default=Enable): If you enable DNS relay, your computers will use the router as a DNS server.
If you disable DNS relay, transfer the DNS server information from your ISP to your computers.

Start IP address: Enter the starting IP addresses for the DHCP server's IP assignment.

Maximum dynamic users: Enter the number of dynamic users. The maximum users you can enter may not

exceed 253, if your dynamic IP address begins with 192.168.127.1

Note: If you statically (manually) assign IP addresses to your computers or devices, make
sure the IP addresses are outside of this range to avoid IP address conflicts.

Client lease time: The length of time for the IP address lease. Enter the Lease time in minutes.

Static IP mapping: If enabled, the mapping list allows you to assign the DHCP IP within the range to your

specific device from MAC address.

OnCell G3111/G3151-HSPA Series Basic Settings and Network Settings

5-5

DNS Settings

You can access DNS Settings by expanding the Network Settings item in the navigation panel.

DNS server 1: This is an optional field. If your network has access to a DNS server, you may enter the DNS

server’s IP address in this field. This allows the OnCell G3111/G3151-HSPA to use domain names instead of IP
addresses to access hosts.

The Domain Name System (DNS) is used to identify Internet domain names, and translate the names into IP
addresses. A domain name is an alphanumeric name, such as www.moxa.com, that it is usually easier to
remember than the numeric IP address. A DNS server is a host that translates this kind of text-based domain
name into the actual IP address used to establish a TCP/IP connection.

When the user wants to visit a particular website, the user’s computer sends the domain name (e.g.,
www.moxa.com) to a DNS server to request that website’s numeric IP address. When the IP address is
received from the DNS server, the user’s computer uses that information to connect to the website’s web
server. The OnCell G3111/G3151-HSPA plays the role of a DNS client, in the sense that it actively queries the
DNS server for the IP address associated with a particular domain name. The following functions in the OnCell
G3111/G3151-HSPA’s web console support the use of domain names in place of IP addresses: Time Server,
Destination IP Address (in TCP Client mode), Mail Server, SNMP Trap Server, and SMTP Server.

DNS server 2: This is an optional field. The IP address of another DNS server may be entered in this field for
times when DNS server 1 is unavailable.

Advanced Network Settings

Access Advanced Network Settings by expanding the Network Settings item in the navigation panel.
Advanced Network Settings is where the gratuitous ARP is configured.

Gratuitous ARP: In some applications, you may need the OnCell G3111/G3151-HSPA to send broadcast
packets to update the ARP table on the server. If you enable this function and set the send period, the OnCell
G3111/G3151-HSPA will periodically send broadcast packets at the specified time interval.

Auto IP Report Settings

You can access Auto IP Report by expanding the Network Settings item in the navigation panel.

When the OnCell G3111/G3151-HSPA products are used in a dynamic IP environment, users must spend more
time with IP management tasks. For example, if the OnCell works as a server (TCP or UDP), then the host,
which acts as a client, must know the IP address of the server. If the DHCP server assigns a new IP address to
OnCell, the host must have some way of determining OnCell’s new IP address.

Port Setting Basics

To configure the operation mode and settings for a port, expand Serial Port Settings in the navigation panel,
and then expand the port that you would like to configure. Individual port settings are grouped into three
categories in the navigation panel: Operation Modes, Communication Parameters, and Data Buffering/Log.

Select Operation Modes in the navigation panel to select and configure the mode for each serial port.

Application: Select an application for the serial port from among the choices. Your application will determine
the modes that are available.

Mode: Once you have chosen an application, select the mode. The available configuration settings will vary
depending on the mode that you have selected.

Device Control Applications

Real COM Mode

TCP alive check time (default=7 min): This field specifies how long the OnCell G3111/G3151-HSPA will wait

for a response to “keep alive” packets before closing the TCP connection. The OnCell G3111/G3151-HSPA
checks connection status by sending periodic “keep alive” packets. If the remote host does not respond to the
packet within the time specified in this field, the OnCell G3111/G3151-HSPA will force the existing TCP
connection to close. For socket and device control modes, the OnCell G3111/G3151-HSPA will listen for another
TCP connection from another host after closing the connection. If TCP alive check time is set to 0, the TCP
connection will remain open and will not send any “keep alive” packets.

ATTENTION

When
application (i.e., 2 hosts are allowed access to t
application, the OnCell G3111/G3151-HSPA will use the serial communication parameters as defined here in
the web console, and all hosts connected to the port must use identical serial settings. If one of the hosts opens
the COM port with different serial settings, data will not be transmitted properly.

ATTENTION

In order to enable a delimiter, packet length must be set to 0. Delimiter 2 should only be enabled in conjunction
with Delimiter 1 and never on its own; otherwise there may be data errors. Even when a delimiter is enabled,
the OnCell G3111/G3151

Max connection (default=1): This field is used if you need to receive data from different hosts
simultaneously. When set to 1, only one specific host can access this port of the OnCell G3111/G3151-HSPA,
and the OnCell COM driver on that host will have full control over the port. When set to 2, the specified number
of hosts’ OnCell COM driver may open this port at the same time. When multiple hosts’ OnCell COM driver open
the port at the same time, the COM driver only provides a pure data tunnel --no control ability unless “Allow
Driver Control” is enabled. The serial port parameters will use firmware settings instead of depending on your
application program (AP).

Application software that is based on the COM driver will receive a driver response of “success” when the
software uses any of the Win32 API functions. The firmware will only send data back to the driver on the host.

Data will be sent first-in-first-out when data comes into the OnCell G3111/G3151-HSPA from the Cellular or
Ethernet interface.

Max connection is greater than 1, the OnCell G3111/G3151-HSPA will use a multi connection

he port at the same time). When using a multi connection

Ignore jammed IP (default=Disable): This option determines how the port will proceed if multiple hosts are
connected and one or more of the hosts stops responding as the port is transmitting data. If you select Disable,
the port will wait until the data has been transmitted successfully to all hosts before transmitting the next group
of data. If you select Enable, the port will ignore the host that stopped responding and continue data
transmission to the other hosts.

Allow driver control (default=Disable): This option determines how the port will proceed if driver control
commands are received from multiple hosts that are connected to the port. If Disable is selected, driver
control commands will be ignored. If Enable is selected, control commands will be accepted, with the most
recent command received taking precedence.

Connection goes down (default=always high): You can configure what happens to the RTS and DTR signals
when the Cellular or Ethernet connection goes down. For some applications, serial devices need to know the
Cellular or Ethernet link status through RTS or DTR signals sent through the serial port. Use “always low” if you
want the RTS and DTR signal to change their state to low when the Cellular or Ethernet connection gets
disconnected. Use “always high” if you do not want the cellular or Ethernet connection status to affect the RTS
or DTR signals.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed
to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum
amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer
is full. When a packet length between 1 and 1024 bytes is specified, data in the buffer will be sent as soon it
reaches the specified length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will queue the data
in the buffer and send the data to the Cellular or Ethernet port when a specific character, entered in hex format,
is received. A second delimiter character may be enabled and specified in the Delimiter 2 field, so that both
characters act as the delimiter to control when data should be sent.

-HSPA will still pack and send the data when the amount of data exceeds 1 KB.

7-4

Delimiter process (default=Do Nothing): The Delimiter process field determines how the data is handled
when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If Delimiters 1 and 2 are
both enabled, both characters must be received for the delimiter process to take place.

• Do Nothing: Data in the buffer will be transmitted when the delimiter is received.

• Delimiter + 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.

• Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received following the
delimiter.

• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.

Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the OnCell
G3111/G3151-HSPA will allow before packing the serial data in its internal buffer for network transmission.

As data is received through the serial port, it is stored by the OnCell G3111/G3151-HSPA in the internal buffer.
The OnCell G3111/G3151-HSPA transmits data stored in the buffer via TCP/IP, but only when the internal
buffer is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and
transmission is determined solely by the data in the internal buffer. At 1 to 65535, the TCP/IP protocol software
will pack the serial data received after there is a gap in serial communication that exceeds the specified force
transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character
interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits,
1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the
time required to transfer one character is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms.

Therefore, you should set the force transmit time to be greater than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series
of characters within the specified force transmit time, and the total length of data must be less than or equal
to the OnCell G3111/G3151-HSPA’s internal buffer size (1 KB per port).

The destination IP address parameter can be the IP address, domain name, or the name defined in the host
table.

Ignore jammed IP (default=Disable): This option determines how the port will proceed if multiple hosts
are connected and one or more of the hosts stops responding as the port is transmitting data. If you select
Disable, the port will wait until the data has been transmitted successfully to all hosts before transmitting the
next group of data. If you select Enable, the port will ignore the host that stopped responding and continue

commands are received from multiple hosts that are connected to the port. If Disable is selected, driver
control commands will be ignored. If Enable is selected, control commands will be accepted, with the most
recent command received taking precedence.

Destination address 1 through 2 (default=None): Specifying an IP address allows the OnCell
G3111/G3151-HSPA to connect actively to the remote host. At least one destination must be provided.

TCP port (default=63950): This is the TCP port number assignment for the remote host/server. It is the port
number that the OnCell G3111/G3151-HSPA’s serial port uses to establish connections with a remote
host/server. To avoid conflicts with well known TCP ports, the default is set to 63950.

Command port (default=63966): The Command port is the COM port for listening to SSDK commands from
the host. In order to prevent a COM port conflict with other applications, the user can set the Command port to
another port if needed.

Designated local port 1 through 2 (default=7010 through 7320): Use these fields to specify the designated local

ports.

Connection goes down (default=always high): You can configure what happens to the RTS and DTR
signals when the Cellular or Ethernet connection goes down. For some applications, serial devices need to know
the Cellular or Ethernet link status through RTS or DTR signals sent through the serial port. Use “always low”
if you want the RTS and DTR signal to change their state to low when the Cellular or Ethernet connection gets

Therefore, you should set the force transmit time to be greater than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series

Inactivity time (default=0 ms): This field specifies how long the OnCell G3111/G3151-HSPA will wait for
incoming and outgoing data through the serial port before closing the TCP connection. The TCP connection is
closed if there is no incoming or outgoing data through the serial port for the specified Inactivity time. If this
field is set to 0, the TCP connection is kept active until a connection close request is received.

Max connection (default=1): This field is used if you need to receive data from different hosts
simultaneously. When set to 1, only a single host may open the TCP connection to the serial port. When set to
2, the specified number of hosts may open this port at the same time. When multiple hosts establish a TCP
connection to the serial port at the same time, the OnCell G3111/G3151-HSPA will duplicate the serial data and
transmit it to all the hosts. Cellular or Ethernet data is sent on a first-in first-out basis to the serial port when
data comes into the OnCell G3111/G3151-HSPA from the Cellular or Ethernet interface.

Ignore jammed IP (default=Disable): This option determines how the port will proceed if multiple hosts are
connected and one or more of the hosts stops responding as the port is transmitting data. If you select Disable,
the port will wait until the data has been transmitted successfully to all hosts before transmitting the next group
of data. If you select Enable, the port will ignore the host that stopped responding and continue data
transmission to the other hosts.

Inactivity time setting should be greater than the Force transmit time. To prevent the

Allow driver control (default=Disable): This option determines how the port will proceed if driver control
commands are received from multiple hosts that are connected to the port. If Disable is selected, driver
control commands will be ignored. If Enable is selected, control commands will be accepted, with the most
recent command received taking precedence.

TCP port (default=4001): This is the TCP port number assignment for the serial port on the OnCell
G3111/G3151-HSPA. It is the port number that the serial port uses to listen to connections, and that other
devices must use to contact the serial port. To avoid conflicts with well known TCP ports, the default is set to

4001.

Command port (default=966): The Command port is the TCP port for listening to SSDK commands from the
host. In order to prevent a TCP port conflict with other applications, the user can set the Command port to
another port if needed.

Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed
to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum
amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer
is full. When a packet length between 1 and 1024 bytes is specified, data in the buffer will be sent as soon it
reaches the specified length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will clear the buffer
and send the data to the Ethernet port when a specific character, entered in hex format, is received. A second
delimiter character may be enabled and specified in the Delimiter 2 field, so that both characters act as the
delimiter to indicate when data should be sent.

ATTENTION

In order to enable a delimiter, packet length must be set to 0. Delimiter 2 should only be enabled in conjunction
with Delimiter 1 and never on its own; otherwise there may be data errors. Even when a delimiter is enabled,
the OnCell G3111/G3151

-HSPA will still pack and send the data when the amount of data exceeds 1 KB.

Delimiter process (default=Do Nothing): The Delimiter process field determines how the data is handled
when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If Delimiters 1 and 2 are
both enabled, both characters must be received for the delimiter process to take place.

• Do Nothing: Data in the buffer will be transmitted when the delimiter is received.

• Delimiter + 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.

• Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received following the
delimiter.

• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.

Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the OnCell
G3111/G3151-HSPA will allow before packing the serial data in its internal buffer for network transmission.

As data is received through the serial port, it is stored by the OnCell G3111/G3151-HSPA in the internal buffer.
The OnCell G3111/G3151-HSPA transmits data stored in the buffer via TCP/IP, but only when the internal
buffer is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and
transmission is determined solely by the data in the internal buffer. At 1 to 65535, the TCP/IP protocol software
will pack the serial data received after there is a gap in serial communication that exceeds the specified force
transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character
interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits,
1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the
time required to transfer one character is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms.

Therefore, you should set the force transmit time to be larger than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series
of characters within the specified force transmit time, and the total length of data must be less than or equal
to the OnCell G3111/G3151-HSPA’s internal buffer size (1 KB per port).

Ethernet Modem Mode

The OnCell G3111/G3151-HSPA accepts the AT command ATD IP address:TCP port (for example, ATD

192.168.127.1:4001) from the serial port and then requests a TCP connection from the remote Ethernet

Modem or PC. Here IP address is the IP address of the remote Ethernet modem or PC, and TCP port is the TCP
port number of the remote Ethernet modem or PC. Once the remote unit accepts this TCP connection, the
OnCell G3111/G3151-HSPA will send out the “CONNECT baud” signal via the serial port and then enter data
mode.

TCP alive check time (default=7 min): This field specifies how long the OnCell G3111/G3151-HSPA will wait
for a response to “keep alive” packets before closing the TCP connection. The OnCell G3111/G3151-HSPA
checks connection status by sending periodic “keep alive” packets. If the remote host does not respond to the
packet within the time specified in this field, the OnCell G3111/G3151-HSPA will force the existing TCP
connection to close. For socket and device control modes, the OnCell G3111/G3151-HSPA will listen for another

Dial-in

The OnCell G3111/G3151-HSPA listens for a TCP/IP connection request from the remote Ethernet modem or
host. The OnCell G3111/G3151-HSPA’s response depends on the ATS0 value, as follows.

ATS0=0:

The OnCell G3111/G3151-HSPA will temporarily accept the TCP connection and then send the RING signal out
through the serial port. The serial controller must reply with ATA within 2.5 seconds to accept the connection
request, after which the OnCell G3111/G3151-HSPA enters data mode. If no ATA command is received, the
OnCell G3111/G3151-HSPA will disconnect after sending three RING signals.

ATS0

1:

The OnCell G3111/G3151-HSPA will accept the TCP connection immediately and then send the “CONNECT

baud” command to the serial port, in which baud represents the baudrate of the OnCell G3111/G3151-HSPA’s
serial port. After that, the OnCell G3111/G3151-HSPA immediately enters data mode.

Dial-out

The OnCell G3111/G3151-HSPA accepts the AT command “ATD IP:TCP port” from the serial port and then
requests a TCP connection from the remote Ethernet Modem or PC. Here IP is the IP address of the remote
Ethernet modem or PC, and TCP port is the TCP port number of the remote Ethernet modem or PC. Once the
remote unit accepts this TCP connection, the OnCell G3111/G3151-HSPA will send out the CONNECT baud”
signal via the serial port and then enter data mode.

Disconnection request from local site

When the OnCell G3111/G3151-HSPA is in data mode, the user can initiate disconnection by sending “+++”
from the local serial port to the OnCell G3111/G3151-HSPA. Some applications allow you to set the DTR signal
to off, which will also initiate disconnection. The OnCell G3111/G3151-HSPA will enter command mode, and
after 1 second, you can then enter ATH to shut down the TCP connection. The OnCell G3111/G3151-HSPA will
return a NO CARRIER via the serial port.

Note: The “+++” command cannot be divided. The “+” character can be changed in register S2, and the guard
time, which prefixes and suffixes the “+++” in order to protect the raw data, can be changed in register S12.

Disconnection request from remote site

After the TCP connection has been shut down by the remote Ethernet modem or PC, the OnCell
G3111/G3151-HSPA will send the NO CARRIER signal via the serial port and then return to command mode.

G3111/G3151-HSPA will allow before packing the serial data in its internal buffer for network transmission.

As data is received through the serial port, it is stored by the OnCell G3111/G3151-HSPA in the internal buffer.
The OnCell G3111/G3151-HSPA transmits data stored in the buffer via SMS, but only when the internal buffer
is full or as specified by the force transmit time. When set to 0, the force transmit time is disabled, and
transmission is determined solely by the data in the internal buffer. At 1 to 65535, the SMS protocol software
will pack the serial data received after there is a gap in serial communication that exceeds the specified force
transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character
interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits,
1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the
time required to transfer one character is

(10 (bits) / 1200 (bits/s)) × 1000 (ms/s) = 8.3 ms.

Therefore, you should set the force transmit time to be larger than 8.3 ms, so in this case, it must be greater
than or equal to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series
of characters within the specified force transmit time, and the total length of data must be less than or equal
to the OnCell G3111/G3151-HSPA’s internal buffer size.

Disabled Mode

When the Application is set to Disable, the relevant port will be disabled.

ATTENTION

The serial parameters for the each serial port on the OnCell G3111/G3151-HSPA should match the parameters
used by the connected serial device. You may need to refer to your serial device’s user’s manual to determine
the appropriate serial communication parameters.

ATTENTION

If the port requires a special baudrate that is not listed, such as G3111/G3151-HSPA00 bps, you may can select
the
automatically calculate the closest supported baudrate. The margin for error will be less than 1.7% for all
baudrates under 921600 bps.

Communication Parameters

Certificate

Ethernet SSL Certificate Import

SSL certificate is used to ensure the website you are accessing is the one you trust, and to encrypt the data
transmitted between you and the website. The SSL certificate contains unique, authenticated information
about the certificate owner. It is issued by a Certificate Authority (CA), such as Verisign, that verifies the
identity of the certificate owner.

The OnCell G3111/G3151-HSPA will generate a new SSL certificate whenever a new IP is used. However, the
SSL certificate is issued by the OnCell itself. If you would like to import an SSL certificate issued by a primary
CA, you can do it from the “Ethernet SSL Certificate Import” page.

The OnCell G3111/G3151-HSPA cellular IP gateway enables traditional serial (RS-232/422/485) devices for
transmitting data over the cellular network. The IP gateway is a tiny computer equipped with a CPU and TCP/IP
protocols that can bi-directionally translate data between the serial and IP formats. With the OnCell
G3111/G3151-HSPA, your computer will be able to access, manage, and configure remote facilities and
equipment over the cellular network from anywhere in the world.

Traditional SCADA and data collection systems rely on serial ports to collect data from various kinds of
instruments. Since the OnCell G3111/G3151-HSPA cellular IP gateway network-enables instruments equipped
with an RS-232, RS-422, or RS-485 communication port, your SCADA and data collection system will be able
to access all instruments connected to a standard TCP/IP network, regardless of whether the devices are used
locally or at a remote site.

The OnCell G3111/G3151-HSPA is an external IP-based network device that allows you to expand a serial port
for a host computer on demand. As long as your host computer supports the TCP/IP protocol, you will not be
limited by the host computer’s bus limitation (such as ISA or PCI), nor will you be limited if you do not have
drivers for various operating systems.

In addition to providing socket access, the OnCell G3111/G3151-HSPA also comes with a Real COM/TTY driver
and a Reverse Real COM/TTY driver that transmits all serial signals intact. This enables you to preserve your
existing COM/TTY-based software without needing to invest in additional software.

Three different socket modes are available: TCP Server, TCP Client, and UDP. The main difference between the
TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient to send an
acknowledgement to the sender. UDP does not require this type of verification, making it possible to offer faster
delivery. UDP also allows you to unicast data to one IP, or multicast the data to a group of IP addresses.

Device Control Applications

The OnCell G3111/G3151-HSPA offers the following modes for device control applications: Real COM, Reverse
Real COM, and RFC2217 modes.

Real COM Modes

The OnCell G3111/G3151-HSPA comes bundled with Moxa drivers for Windows
NT/2000/XP/2003/2008/Vista/7 systems and TTY drivers for Linux and Unix systems. (For Windows systems,
this option is only supported for Windows 2000, XP x86/x64, 2003 x86/x64, Vista x86/x64, 2008 x86/x64 and
Windows 7 x86/x64.)

In Real COM mode, the bundled drivers are able to establish a transparent connection between a host and a
serial device by mapping the serial port on the OnCell G3111/G3151-HSPA to a local COM/TTY port on the host
computer. Real COM mode supports up to 2 simultaneous connections that enable 2 hosts to simultaneously
collect data from the same serial device.

One of the major conveniences of using Real COM mode is that it allows you to use software that was written
for pure serial communication applications. The OnCell COM driver intercepts data sent to the host’s COM port,
packs it into a TCP/IP packet, and then redirects it through the host’s Ethernet card to the Internet. At the other
end of the connection, the OnCell G3111/G3151-HSPA accepts the IP frame from the cellular network, unpacks
the TCP/IP packet, and then transparently sends the data through the serial port to the attached serial device.

Types of Real COM Connections

This section illustrates the types of Real COM connections you can use, depending on the service you obtain
from your local cellular service provider.

1. Fixed Public IP for OnCell.
If your cellular service provider offers a fixed public IP address after you connect to the cellular network,

you can access the OnCell G3111/G3151-HSPA via a host PC using either a private IP or public IP.

2. Utilize Auto IP report.
If your cellular service provider offers a dynamic public IP address after you connect to the cellular network,

you can access the OnCell G3111/G3151-HSPA via a host PC using a fixed public IP. Since the IP address

OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

A-3

of the OnCell G3111/G3151-HSPA is changed each time it is connected to the cellular network, the host IP
can be notified of the change by an Auto IP Report message sent from the OnCell G3111/G3151-HSPA.
Refer to Appendix E to see the format of the Auto IP Report Protocol.

3. Domain name with DDNS.
If your cellular service provider offers a public IP address after you connect to the cellular network, you can

also access the OnCell G3111/G3151-HSPA using the domain name. To do this, you will need to register
with a DDNS service provider and then enable the DDNS function in the OnCell G3111/G3151-HSPA. Refer
to Appendix C for more information.

Reverse Real COM Modes

The OnCell G3111/G3151-HSPA comes bundled with Moxa drivers for Windows
NT/2000/XP/2003/2008/Vista/7 systems and TTY drivers for Linux and Unix systems. (For Windows systems,
this option is only supported for Windows 2000, XP x86/x64, 2003 x86/x64, Vista x86/x64, 2008 x86/x64 and
Windows 7 x86/x64.)

Reverse Real COM mode uses a mechanism similar to port mapping to enable your remote device that is using
a private IP address to remain accessible to external hosts. When this mode is enabled, the Moxa driver that
comes with the device establishes a transparent connection from the device to the remote host by mapping the
device’s serial port to a local COM port on the remote host. Reverse Real COM mode supports up to 2
simultaneous connections that enable serial devices to send data to 2 hosts simultaneously.

A-4

Types of Reverse Real COM Connection

1. Reverse Real COM to PC’s IP address.
Most cellular service providers only provide customers with a dynamic private IP address, which means that

the OnCell G3111/G3151-HSPA will only obtain an IP address once it is connected to the cellular network.
Reverse Real COM is a great feature that allows a PC host to access an OnCell G3111/G3151-HSPA
configured with a private IP address.

2. Reverse Real COM to PC’s domain name.
With Reverse Real COM mode, you can connect to a PC host using the PC’s IP address. You can also connect

to your PC host with the PC’s domain name, if you have one. Refer to Appendix C for more information.

RFC 2217 Mode

RFC-2217 mode is similar to Real COM mode in that a driver is used to establish a transparent connection
between a host computer and a serial device by mapping the serial port on the OnCell G3111/G3151-HSPA to
a local COM port on the host computer. RFC2217 defines general COM port control options based on the Telnet
protocol. Third party drivers supporting RFC-2217 are widely available on the Internet and can be used to
implement virtual COM mapping to your OnCell G3111/G3151-HSPA’s serial port. Refer to Appendix B for more
information.

Socket Applications

The OnCell G3111/G3151-HSPA offers the following modes for socket applications: TCP Server, TCP Client, and
UDP.

TCP Server Modes

In TCP Server mode, the serial port on the OnCell G3111/G3151-HSPA is assigned a port number. The host
computer initiates contact with the OnCell G3111/G3151-HSPA, establishes the connection, and receives data
from the serial device. This operation mode also supports up to 2 simultaneous connections, enabling multiple
hosts to collect data from the same serial device at the same time.

As illustrated in the figure, data transmission proceeds as follows: The host requests a connection from the
OnCell G3111/G3151-HSPA, which is configured for TCP Server mode. Once the connection is established, data
can be transmitted in both directions between the host and the OnCell G3111/G3151-HSPA.

OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

A-5

Types of TCP Server Connection

1. Fixed Public IP for the OnCell.
If your cellular service provider offers a fixed public IP address after you connect to the cellular network,

you can access the OnCell G3111/G3151-HSPA from a host PC using either a private IP or public IP.

2. Using Auto IP report.
If your cellular service provider offers a dynamic public IP address after you connect to the cellular network,

you can access the OnCell G3111/G3151-HSPA from a host PC using a fixed public IP. Since the IP address
of the OnCell G3111/G3151-HSPA is changed every time it is connected to the cellular network, the host IP
can be aware of the change by the Auto IP Report message sent from the OnCell G3111/G3151-HSPA. Refer
to Appendix E for the format of the Auto IP Report Protocol.

3. Domain name with DDNS.
If your cellular service provider offers a public IP address after you connect to the cellular network, you can

also use the domain name to access the OnCell G3111/G3151-HSPA. You would need to register with a
DDNS service provider and then enable the DDNS function in the OnCell G3111/G3151-HSPA. Refer to
Appendix C for more information.

4. Connecting TCP client and TCP server within the same cellular service provider.
In order to connect properly, the IP addresses of the two OnCell devices must belong to the same

subnetwork. To ensure that this is the case, use the same cellular service provider to connect the devices
to the network. In addition, you will need to request that the cellular service provider provide you with two
private IP addresses (e.g., 192.168.1.1 and 192.168.1.2).

TCP Client Modes

In TCP Client mode, the OnCell G3111/G3151-HSPA can actively establish a TCP connection to a pre-defined
host computer when serial data arrives. After the data has been transferred, the OnCell G3111/G3151-HSPA
can automatically disconnect from the host computer by using the Inactivity time settings.

As illustrated in the figure below, data transmission proceeds as follows:

(1) The OnCell G3111/G3151-HSPA, configured for TCP Client mode, requests a connection to the host.

(2) Once the connection is established, data can be transmitted in both directions between the host and the
OnCell G3111/G3151-HSPA.

Types of TCP Client Connection

1. TCP Client to PC’s IP address.
The OnCell G3111/G3151-HSPA will only be able to connect to a host PC if the PC is using a public IP

address.

OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes

A-7

2. TCP Client to PC’s domain name.
To connect to a host PC, the host PC must be configured with public IP address. If it is using a dynamic

public IP, then the OnCell G3111/G3151-HSPA can connect to it using the host’s domain name. Refer to
Appendix C for more information.

3. Connecting TCP client and TCP server within the same cellular service provider.
In order to connect properly, the IP addresses of the two OnCell devices must belong to the same

subnetwork. To ensure that this is the case, use the same cellular service provider to connect the devices
to the network. In addition, you will need to request that the cellular service provider provide you with two
private IP addresses (e.g., 192.168.1.1 and 192.168.1.2).

UDP Mode

Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can unicast to one host
or multicast to multiple hosts and the serial device can receive data from one or multiple host computers. These
traits make UDP mode especially well suited for message display applications.

A-8

Types of UDP Connection

1. Fixed Public IPs for both OnCell and Host PC.
If your cellular service provider offers a fixed public IP address after you connect to the cellular network,

you can access the OnCell G3111/G3151-HSPA from a host PC that has a fixed public IP.

2. Domain name with DDNS.
If your cellular service provider assigns a public IP address after you connect to the cellular network, you

can also access the OnCell G3111/G3151-HSPA using the domain name. If your service provider assigns a
public IP address (either fixed or dynamic) to your cellular device and your control center is the side that
initiates the connection, you can enable the DDNS function and UDP mode to allow other devices on the
Internet to connect to your device using its domain name. This will ensure that your device will remain
reachable even when its public IP address is updated. Note that you will need to register your device with
a DDNS server. Refer to Appendix C for more information.

Ethernet Modem Mode

Ethernet Modem mode is designed for use with legacy operating systems, such as MS-DOS, that do not support
TCP/IP networks. By connecting a properly configured OnCell G3111/G3151-HSPA serial port to the MS-DOS
computer’s serial port, it is possible to use legacy software to transmit data over the cellular network, even if
the software was originally designed to transmit data through a modem. In this case, the AT commands are
converted into IP format.

SMS Tunnel Mode

A major benefit of GSM technology is that it supports short messages (SMS) for easy communication over the
mobile network. Moxa’s proprietary SMS Tunnel Mode allows you to expand your applications and reduce cost.
For example, SMS Tunnel Mode can be used to update the message on a highway display panel, place refill
orders for vending machines, handle maintenance for remote rental equipment, or even help create an SMS
alarm by directly transforming text, binary, or unicode data from a legacy device to short messages. SMS
Tunnel Mode is particularly suitable for devices that communicate infrequently, or lack access to the local
network. SMS Tunnel Mode converts ASCII, binary code, and UCS2 data to short messages transparently (both
back and forth). In addition, the caller ID (phone number) identification can be used to block messages sent
from uncertified users, broadcast messages, and unwanted SMS advertisements.

Moxa’s proprietary SMS Tunnel Mode has the following features:

1. Transparently converts serial data to short message, and vice versa.

2. Text, binary, and Unicode formats are supported.

3. Verification of Incoming Caller ID calls is implemented to block uncertified users.

Disabled Mode

You can disable the serial port on the OnCell G3111/G3151-HSPA by setting the operation mode to Disabled.
