1.2 AceWare™

A wireless solution is not complete until you have software tools to manage the
devices monitoring your valuable equipment. AceWare™ is the device
management and monitoring application suite for RadioLinx Intelligent Cellular
products powered by ALEOS.

These modem utilities, except AceNet, are free of charge to those who own
Intelligent Cellular modems. You can download the applications and their user
guides from the ProSoft Solutions web site: www.prosoft-technology.com.
Contact your dealer or ProSoft Technology representative for information on
AceNet.

AceManager, the AceWare remote configuration and monitoring tool, simplifies
deployment, and provides extensive monitoring, control and management
capabilities. AceManager gives you the power to monitor and control your
RadioLinx communications platforms in real time.

Simplified Deployment

AceManager provides the ability to remotely set up and configure your RadioLinx
Intelligent Cellular products. Remote device setup and configuration reduces the
deployment timeline of your wireless solution, and provides a quicker path to
ROI.

Templates allow you to easily configure other devices in your fleet with identical
settings, ensuring a simple, accurate deployment.

Monitor and Control

AceManager allows an administrator to remotely monitor a modem's status,
health, and configuration settings. The user interface displays signal strength,
cell site information, byte counters, and error conditions, enabling you to locate
any issues, and troubleshoot immediately.

AceManager enables remote configuration and parameter settings to be changed
or reset instantly over the air, change a device's port configuration, IP address
settings, and much more. After configuring one modem, use the template feature
to copy that device configuration to other modems.

Tip: Configuration steps and examples in this guide use AceManager.

AceNet, the enterprise grade productivity enhancing tool, enables you to
efficiently deploy, and monitor RadioLinx Intelligent Cellular products on a large
scale.

User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

Network Monitoring

AceNet allows you to efficiently deploy, monitor, and maintain wireless networks
of any size by enabling you to quickly configure an entire group of RadioLinx
modems to the same parameter settings using templates built with AceManager.

To ensure your implementation is optimal, users can easily see when modems
are out of contact, and periodically poll each device for performance statistics.

AceView is an efficient status and connection monitoring application with a low­profile, easy to read interface.

1.2.1 Modem Doctor

Modem Doctor is a troubleshooting and diagnostics utility. This utility will allow
you to get a log file of the RLXIC-SG activity which you can then send to ProSoft
Technology support, erase the current configuration completely, and temporarily
set the RLXIC-SG to a known configuration to aid in trouble shooting (SOS
mode).

1.3 Connecting to your cellular provider

The RLXIC-SG uses your cellular provider as an ISP (Internet Service Provider)
to connect you to the Internet.

1.3.1 Steps of a connection:

1 When your RLXIC-SG is powered on, it automatically searches for cellular

service using GSM/GPRS.

2 Your RLXIC-SG establishes a PPP (Point to Point Protocol or "dial" up

connection) link to the your cellular provider network, also called registering
on the network, and receives an IP address.

ProSoft Technology, Inc. Page 9 of 136
May 29, 2009

RLXIC-SG ♦ Intelligent Cellular Introduction to the RLXIC-SG
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

3 When your RLXIC-SG has received its IP address from your cellular provider,

a connection to the Internet or the cellular network is also available for a
computer or other device connected directly to the RLXIC-SG.

The RLXIC-SG will perform a one-to-one routing for all internet traffic to and
from the computer or other end device. One-to-one means that your RLXIC-SG
will provide a connection for one device to the Internet at a time. In Private Mode,
the RLXIC-SG will provide NAT (Network Address Translation) for the computer
or other end device.

Note: The RLXIC-SG does not provide advanced routing required by one-to-many (several devices
connected to one port). If you need to have more than one device connected to the Internet
through your RLXIC-SG, you will need to have a router connected to the modem. The modem
would provide the one-to-one connection to the router with the router configured to provide a
broader NAT service to the other devices connected to it.

1.3.2 Dynamic vs. Static IP Addresses

There are two types of addresses on networks: dynamic and static.
 Dynamic addresses are assigned on a "need to have" basis. Your RLXIC-SG

might not always receive the same address each time it connects with your
cellular provider.

 Static addresses are permanently assigned to a particular account, and will

always be used whenever your RLXIC-SG connects to the Internet. The IP
address will not be given to anyone else.

Most ISPs (cellular included) use dynamic IP addresses rather than static IP
addresses, because it allows them to reuse a smaller number of IP addresses for
a large number of customers. A dynamic IP address is suitable for many
common Internet uses, such as web browsing, looking up data on another
computer system, or other client functions (such as data only being sent out or
only being received after an initial request).

Tip: If your account with your cellular provider includes a dynamic IP address, and you need a
static IP, please consult your cellular provider Representative for more information about changing
your account for static IP support.

May 29, 2009

Introduction to the RLXIC-SG RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

If you need to contact your RLXIC-SG, a device connected to the RLXIC-SG, or
a host system using the RLXIC-SG from the Internet, you need to have a known
IP (such as one which is static) or domain name (an IP address which is
converted by a DNS server into a word based name). If you have a dynamic IP
address for your modem, you can use a Dynamic DNS service (such as IP
Manager) to translate your IP address into to a domain name.

Caution: If you want to connect remotely to your RLXIC-SG using TCP/IP, the IP address given to
your modem by your cellular provider cannot be a private or internal IP address (such as a custom
APN or special private network Data Link) unless you are on the same network or inside that
network's firewall (such as with frame relay).

1.4 GSM

GSM Networks use SIM cards which are smart cards containing the account
holder's details. A SIM can generally be moved from one device to another
allowing for account portability and flexibility.

1.4.1 GPRS

General Packet Radio Service (GPRS) is packet-switched with many users
sharing the same transmission channel, but only transmitting when they have
data to send. This means that the total available bandwidth can be immediately
dedicated to those users who are actually sending at any given moment,
providing higher utilization where users only send or receive data intermittently.
GPRS provides speeds of 30- to 70 kbps with bursts up to 170 kbps.

3.2 Configuring the APN

The APN (Access Point Name) is the way your modem knows how it will be
communicating with the network. The APN allows custom IP addressing and
tailoring your company's wireless IP solution to meet the security and IP
addressing requirements of your applications.

Note: Most accounts use the default addressing solution of Private or Public IP addresses supplied
by the Internet and Proxy APNs. Only if you have a Static or Custom IP address should you need
to configure a custom APNs.

The default APN is Internet. If you need a different APN, use AceManager to
configure it.



Mounting................................................................................................26

Note: During installation, please be sure that the cables are secure but do not bear any additional
weight that could loosen the connector from the unit.

Your RLXIC-SG should be mounted in a position that allows easy access for the
cables so they are not bent, constricted, in close proximity to high amperage, or
exposed to extreme temperatures. The LEDs on the front panel should be visible
for ease of operational verification. You should ensure that there is adequate
airflow around the modem but that it is kept free from direct exposure to the
elements, such as sun, rain, dust, etc.

Caution: The RLXIC-SG is in a hardened case, and designed for use in industrial and extreme
environments. However, unless you are using cables expressly designed for such environments,
they can fail if exposed to the same conditions the RLXIC-SG can withstand.
Note: This device is not intended for use within close proximity of the human body. Antenna
installation should provide for at least a 20 CM separation from the operator.

ProSoft Technology, Inc. Page 23 of 136
May 29, 2009

RLXIC-SG ♦ Intelligent Cellular Hardware Installation of the RLXIC-SG
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

Antennas selected should not exceed a maximum gain of 5 dBi under standard
installation configuration. In more complex installations (such as those requiring
long lengths of cable, and/or multiple connections), it is imperative that the
installer follow maximum dBi gain guidelines in accordance with the radio
communications regulations of the Federal Communications Commission (FCC),
Industry Canada, or your country's regulatory body (if used outside the US).

Your RLXIC-SG will work with most cellular antennas with a SMA connector.
Connect the primary antenna or primary RF cable directly to the antenna
connector on the back of the RLXIC-SG.

Tip: When using a cable to an antenna placed away from the modem, minimize the length of your
cable. All gain from a more advantageous antenna placement can be lost with a long cable to the
modem.

4.1 Connecting to Power

This I/O port handles external input and output events. An external device can
send digital input to the modem, through the digital I/O port.

Your RLXIC-SG can be used with either DC or AC, with the appropriate power
adapter. DC cables and AC adapters are available as optional accessories in
addition to the one included with your RLXIC-SG.

The color wires are:
 BLACK

(2 conductor) = Ground

 RED (1 conductor) = Power

Note: When using a DC power source (such as a solar cell), ProSoft Technology recommends
placing a fuse (1-2 Amp) on the line close to the power source to protect your power source from
possible surges due to shorts or other line issues.

The DC power cable positive lead should be connected to the battery or power
source positive terminal. The power cable negative lead should be connected to
the battery or power source negative terminal.

Tip: The DC power cable has a white wire lead in addition to the power positive and negative. This
is for a feature not present in the RLXIC line modems. In the RLXIC-SG, the white wire lead has no
function and can be ignored.

Warning: Explosion Hazard - Do not disconnect equipment unless power has been switched off or
the area is known to be non-hazardous.

4.2 Connecting to a Computer or other Device

Your RLXIC-SG's full-speed (12 Mbit) USB 2.0 port can
be connected directly to most computers or other devices
using a standard full-speed USB 2.0 cable. If the
computer or device you are connecting or the cable is not
rated for full-speed, the modem will communicate at a
reduced speed to match. The RLXIC-SG functions as a
device, not a host.

When it is connected to a computer, the USB port should be seen as a COM port
or Ethernet port after the applicable driver is installed.

The RLXIC-SG has a standard mini-B connector.

Warning: The USB port can only be used in a non-hazardous environment.

4.3 Indicator Lights

When your RLXIC-SG is connected to power and
an antenna, there is a specific pattern to the lights
to indicate its operation mode.

 Network - Indicates a successful connection

to the cellular network with an IP address
given, and a channel acquired.

 Signal - Light shows the strength of the

signal, and may be nearly solid (strong signal)
or flashing (weaker signal). A slow flash
indicates a very weak signal.

4.3.1 RSSI LED Ranges

RSSI/Signal LED Status Ranges of RSSI (dBm)

On Solid Equal to or stronger than -69
Fast Blink -70 to -79
Normal blink -80 to -89
Slow Blink -90 to -99
Extinguished Equal to or weaker than -100

 Activity - Lights will flash as data is transferred to and from the RLXIC-SG

modem on the remote network.

 Power - Indicates the power adapter is connected, and there is power getting

to the RLXIC-SG.

In This Chapter

 Using AceManager................................................................................29



Using Templates ...................................................................................32

 Using a Terminal Application with AT Commands.................................36

With ALEOS as its "brain", the RLXIC-SG is a highly configurable device, more
than just a "dumb" modem.

To configure your RLXIC-SG, you have two options. You can use the
configuration and management applications of the AceWare suite or you can use
a terminal emulator application such as HyperTerminal, PuTTY, or many others.

Because the AceWare applications are designed for ease of use, nearly all
descriptions and screen shots of RLXIC-SG configuration in this guide and
Application Notes are done with AceManager. In addition to the various chapters
in this guide giving information and directions about using the features of your
RLXIC-SG, the Configuration Commands appendix briefly describes all the
commands available. To get a more expanded view of the other AceManager
features, refer to the AceManager Guide.

Refer to Configuration Commands for a full listing of the available commands
(page

89).

5.1 Using AceManager

AceManager is a free utility and is available on the product CD or can be
downloaded from the ProSoft Technology website.

5.2.2 Applying a Template to one modem with AceManager

You can use a template you created yourself, using the steps above, or a
template provided by your RadioLinx representative or someone in your
company who has set up a modem template. The template you wish to apply
must be saved to your hard drive.

1 Load the template.

a Connect to the modem you want to configure using AceManager.
b Click the L

c Select the template you have saved (you may need to change folders if

you saved it to a different location).

2 Verify the configuration settings.

Tip: After you load the template, it is best to go back over the AceManager groups to make sure all
the settings are what you require.

3 Click the W

RITE button on the toolbar to write the configuration to the modem.

Wait for the "Write Successful" message.

4 Reset the modem.

Caution: Many of the configuration settings will not take effect until the modem has been reset.
Tip: You can use common settings on one modem to configure those same settings on another

modem even of a different type. For example, you can use the serial settings of a modem (such as
RLXIC-SG, SV) to configure the serial settings of a RLXIC-SG. Settings not applicable to the
modem on which you are loading the template, will be discarded.

5.2.3 Optional: Applying one template to several modems
simultaneously with AceNet

AceNet allows you to connect to and monitor several modems at the same time.
For your convenience, you can also apply a single template to selected modems
simultaneously.

Connecting to the modems with AceNet is covered in the AceNet User Guide.

Caution: When applying a template in AceNet, it is even more important to make sure there are no
non-general settings in the template from the "master" modem.

Unlike AceManager, AceNet does not check the modem type before applying the
template. Settings not applicable, such as a USB setting from a RLXIC-SG
template being applied to a modem of a different type, are not read by the
receiving modem. You will get a "partial success" status if all items in a template
cannot be applied by the receiving modem.

1 Select modems to configure with the template.

The RLXIC-SG is equipped with a USB port which increases the methods by
which you can send and receive data. The USB port can be set to work as either
an Ethernet port or a virtual serial port. A driver installation is required to use the
USB port in either mode.

Note: It is recommended that you use a USB 2.0 cable with your RLXIC-SG and connect directly to
your computer for best throughput.

6.1 Changing the USB port communication

The command to change the port configuration is *USBDEVICE, and it is in the
USB group of AceManager.

By default, the port is set to work as a virtual Ethernet port (*USBDEVICE=1).
To change the USB port to allow virtual serial port communication, disable the

Ethernet port emulation, set *USBDEVICE to 0.

Note: If you use a terminal connection with the USB port to change *USBDEVICE, the change is
immediate. Your connection will be terminated after inputting the command.



Keepalive...............................................................................................65

Note: This section describes general communication options for the RLXIC-SG. For specific
information regarding configuration of the RLXIC-SG for different industrial applications, refer to the
application notes and templates on the RadioLinx CD.

The RLXIC-SG plays the part of a HOST when a computer or another device is
connected directly to its port, and routes data to/from the connected device to the
cellular network.

Tip: If you need to have one-to-many routing, you can connect the RLXIC-SG to a router. The
router would provide the multiple routing, and the RLXIC-SG would provide one-to-one for the
router to the cellular network and the Internet.

As the host, the RLXIC-SG can use different communication modes:

7.1.1 Basic Modes

 AT: The RLXIC-SG accepts and responds to standard AT commands.
 PassThru: Direct connection to internal hardware (OEM Module) of the

RLXIC-SG.

 Telnet: The RLXIC-SG auto-answers TCP connections to allow terminal

emulation using either a local USB Ethernet connection or remotely using the
cellular connection.

Tip: By default, the RLXIC-SG is in AT Mode, and allows AT Commands to be entered via terminal
connection (through the local port connection) or remotely (through the cellular network). PassThru
Mode can only be exited by resetting the RLXIC-SG. All serial modes are entered by use of a
startup mode command.

computer connected to the serial or USB port.

 UDP and UDP PAD: Any data received on the serial port is assembled into

UDP packets, and sent to the session's associated IP address and Port
(described later). Any responses received from the associated IP address
and port destined for the Device Port are unwrapped, and sent out the serial
port.

 TCP and TCP PAD: Any data received on the serial port is packaged into

TCP messages, and sent to the associated connection's IP address and Port
(described later). Any data received from the TCP peer is unwrapped and
sent out the serial.

7.1.3 Data Communication

 Public and Private Modes: The method used by the RLXIC-SG to pass an

IP address to a connected device.

 Keepalive: How the RLXIC-SG maintains its connection to the cellular

network.

7.2 Basic Modes

7.2.1 Start up Mode

The serial port of the RLXIC-SG can be configured to enter any of the modes
automatically on power up (in most cases, this is also after it has registered on
the cellular network). This is done by setting the Startup Mode Default to the
desired mode. If this setting is non-zero, the modem will enter the specified mode
after 5 seconds. If you want to cancel this behavior, the ATMD0 command can
be used before the 5-second time-out expires.

You can configure the Startup Mode in AceManager at part of the UDP

group.

Data Communication and Host Modes RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

 If the serial port of the RLXIC-SG is in any mode other than AT or PassThru,

the AT command mode can be re-entered by:

 Deactivating DTR (if &D2 or Ignore DTR, S211, is not set).
 Issuing the +++ escape sequence (if Disable AT Escape, DAE, is not set).
 Resetting or Power cycling the modem.

Note: DTR needs to be asserted (S211=1 or &D0) by the host before PPP Mode, SLIP Mode, UDP
PAD Mode, or TCP PAD Mode can be entered.

7.2.2 AT Mode

Using a terminal connection, AT commands are used to configure the modem,
command it to do something, or query a setting. For a full listing of the AT
commands, refer to the appendix. AceManager is a graphical user interface for
most AT Commands.

 AT commands must always be terminated by <CR> (ASCII character 0x0D),

a carriage return (pressing enter on the keyboard). Some may also include a
new line or line feed <LF>.

 If E=1 (Echo On), the AT command (including the terminating <carriage

return) will be displayed (output) before any responses.

 Two settings affect the format of AT command output: V (Verbose), and Q

(Quiet).

 If Q=1 (Quiet On), no result codes are output whatsoever, so there is no

response generated by a (non query) command.

 If Q=0 (Quiet Off), result codes are output. The format of this output is then

affected by the Verbose setting.

If Quiet mode is off, the result code is affected as follows:
For V=1 (Verbose mode), the textual result code is surrounded by a carriage

return and new line. Any AT query response is also surrounded by a carriage
return and new line.

For V=0 (Terse mode), a numeric result code is output with a single trailing
carriage return (no new line is output), while any AT query response is followed
by a carriage return and new line (there is no preceding output).

 For example, possible output to the AT command "AT" with carriage return

(assuming quiet mode is not on) is:
carriage return - if V=0

carriage return and new line OK another carriage return and new line - if V=1

Note: These commands work for the port on which they are executed. For example, if the user
types ATE1, and then AT&W using a serial port connection, it will set the serial port to Echo On.

RLXIC-SG ♦ Intelligent Cellular Data Communication and Host Modes
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

7.2.3 PassThru Mode

In PassThru mode, the RLXIC-SG does not behave normally, all port
communication is passed directly between the internal hardware and the
computer connected directly to the modem. This mode can be used to configure
hardware-specific settings. For example, provisioning, troubleshooting,
communicating with legacy equipment, etc.

Caution: ALEOS is disabled in PassThru Mode. You cannot use most ALEOS specific commands
while the modem is in PassThru Mode.

Issuing the "AT\APASSTHRU" from a terminal emulation enters this mode. The
modem responds with OK, at which point a direct connection to the internal
hardware is established. You can also configure the modem to enter PassThru
mode on start up using MD.

Tip: PassThru can only be exited by resetting or power-cycling the modem. This mode cannot be
entered via a remote Telnet session.

You can configure a string of AT commands to be sent to the RLXIC-SG when it
enters PassThru, and other PassThru settings.

PassThru Mode allows only specific AT commands. Some ALEOS commands
will be unavailable when the RLXIC-SG is in PassThru mode. The commands
usable also depend heavily on the modem model number (found on the label on
the top of the RLXIC-SG).

Note: Some internal hardware requires upwards of 20 seconds before AT commands can be
entered, so be patient if there seems to be no response to AT commands.

7.2.4 Telnet Mode

In AceManager you can configure Telnet operation.

If you need to change the port for Telnet (for example, you have the default port
blocked on your firewall), the option is on the O

2332. You can also change the Telnet timeout, if the connection is idle, default

is
2 minutes.

7.3 Serial Modes

7.3.1 PPP

In PPP mode, the RLXIC-SG acts as a PPP server, providing an IP address, and
DNS servers (if available) to the connected device or computer.

PPP mode is entered from the AT mode by using any of the following
commands:

 AT\APPP
 ATDT10.0.0.1
 ATDT10001
 ATD#19788 or #777 *99***1#
 CLIENT

ProSoft Technology, Inc. Page 55 of 136
May 29, 2009

RLXIC-SG ♦ Intelligent Cellular Data Communication and Host Modes
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

In response to any of the preceding commands, the RLXIC-SG will respond with
CONNECT a carriage return and new line and is ready for the host to begin PPP
negotiations. The IP received by the host in the resulting negotiation will either be
a private (non-routable) IP address or a public (network-routable) IP address
provided by the network, depending on the settings of *HOSTPRIVMODE. If
*HOSTPRIVMODE=1, the value of the private IP address can be determined
beforehand by querying S110. The private IP address to be used can be defined
with the command AT*HOSTPRIVIP=192.168.100.33, substituting the desired IP
address.

Using a private IP insulates the PPP client from changes in IP addresses of the
underlying network. The will perform basic NAT-like address translation on all
packets.

If a public IP address is being used, any changes in the IP (as determined by the
wireless network) will result in the PPP link to the host being disconnected,
requiring the host to reinitiate it. The public IP is passed to the host in the PPP
negotiations, so when the network forces a change, the modem has to force the
host to renegotiate the PPP link to make this happen.

7.3.2 SLIP

SLIP mode is entered be using the "AT\ASLIP" command. As in PPP Mode, the
IP address that the host assumes is affected by the setting of
*HOSTPRIVMODE. SLIP does not negotiate the IP address with the connected
device or computer, so before making a SLIP connection, the SLIP driver on that
device or computer must be configured to use the IP address specified by
querying S110.

Data Communication and Host Modes RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

 When the modem is in UDP PAD (Packet Assembly and Disassembly) Mode,

all characters received on the serial port are assembled into UDP packets,
and sent to the remote IP address/port or the RLXIC-SG, and any packets
received from the same IP/port-destined for the device port of RLXIC-SG
(see *DPORT)--are disassembled, and dumped onto the serial line.

A UDP session is initiated by one of the following events:

 Using the Dial UDP (DP) AT command (example, ATDP192.168.3.23/3456).
 Setting the Startup Mode Default (MD) to 3 (UDP) so that a UDP session is

entered automatically when the modem registers onto the network. Serial
data will be sent to the IP/port specified in S53.

Incoming UDP packets will be processed out the serial port if

 UDP auto answer is enabled (S82=2);
 The destination IP address matches that in S53 (if Friends Mode is enabled,

the IP address also needs to be present on the Friends List);

 Or allow any IP is set (AIP=1);
 The modem is in AT mode (not in a current UDP or TCP session).

UDP packet assembly is affected by the values of S50 (PAD Forwarding Time­out) and S51 (PAD Forwarding Character). Data received in the serial buffer will
be transmitted when the idle inter-character time-out specified in S50 (in tenths of
seconds) occurs or when a character is received that matches S51 (if non-zero).

7.3.3 UDP Auto Answer

UDP auto answer (previously called UDP half-open) is set with S82=2. When set,
the RLXIC-SG will automatically establish a UDP session to the source IP
address, and port of the UDP packet received. The RLXIC-SG will remain
"locked" to this one remote IP/port until no data is sent or received for the time
interval defined in the UDP auto answer time-out (S83). During this session,
packets from other IP/port addresses will be rejected, unless *UALL is set.
Whether or not an incoming packet will cause the modem to enter a UDP session
is always dependent on the S53 and AIP settings.

The Normal UDP Mode (MD3) can be combined with UDP auto answer to cause
the incoming serial data to be sent in UDP packets (instead of being treated as
AT commands), while allowing sessions to be established from different UDP
sources. A UDP session will be initiated either by incoming serial data or by an
incoming UDP packet. The session, started by either method, will be terminated
when no data has been sent or received for the S82 period. After the session
terminates, another may be initiated by either means.

When idle, after the time-out has occurred, the modem is in AT command mode
on the serial port, and any valid AT command may be entered during this time.

Tip: It is best to ensure the idle time-outs for TCP and UDP are never 0 if you're going to be using
auto-answer, or either PAD mode. In those circumstances, you will want the modem to close the
socket if the connection goes idle for too long, particularly if the other side does not normally close
the connection.

ProSoft Technology, Inc. Page 57 of 136
May 29, 2009

RLXIC-SG ♦ Intelligent Cellular Data Communication and Host Modes
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

When the session is initiated by serial data, the new session will be established
using the destination address specified in S53. The S53 setting can be changed
if the connect to last UDP setting (*UDPLAST=1) is set. The address in S53 will
be updated to reflect the address of the last session initiated by an incoming
UDP packet. So that when new data is received over the host serial port while in
the idle state, a session will be re-established with the last address. (This
behavior is the same as the previous Hybrid2 (MD6) mode).

Tip: TCP auto answer (S0) may also be set simultaneously with UDP auto answer. Then, when in
the idle state, the modem will accept either a TCP or UDP incoming packet, and enter a TCP or
UDP session as appropriate.

Reliable UDP

Reliable UDP adds a simple protocol on top of UDP to provide reliable delivery of
data. When data is received from the host serial port, a 2 byte header is added to
the data, containing a message type and a sequence number. The RLXIC-SG
will continue to send this data (buffering any received data in the meantime) until
it receives an acknowledgement with this sequence number. If an
acknowledgement is not received within the time-out period (specified in S7), the
data will be retransmitted. This will continue until an acknowledgement is
received or the modem is reset. Likewise any UDP packets received by the
RLXIC-SG are expected to have this simple header. The RLXIC-SG will issue an
acknowledgement for any valid packets which are received.

To configure the RLXIC-SG for a normal UDP session, you need to set the
Startup Mode Default to 73 (ATMD73). If you are using two modems, configure
the Destination IP and Port in each to point to each other. Serial data will then be
sent reliably between the two.

Caution: Although it adds reliability, the simple implementation of the Reliable UDP mode in the
RLXIC-SG does not check for duplicate packets.

UDP Multicast Mode

UDP Multicast mode results in any data received from the host serial port being
sent to all the clients in the address list. The remote port number is taken from
S53. To avoid flooding the network, the packets are sent to each client with a
20ms pause in between. The receipt of UDP packets works as in normal UDP
mode (that is, bound by the value S53 and/or AIP). Because it may take a while
to transmit the data to all hosts (especially if all 20 Modbus entries are used and
name resolutions are required), new data received from the host port is buffered
until current transmissions to all hosts are finished.

Enter the list of target IPs in the address list (ADDR LIST). The index numbers in
the list are not used. Configure for a normal UDP session. Set the Startup Mode
Default to 83 (ATMD83). Configure the Destination port to match the device port
of the remote modems.

Data Communication and Host Modes RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

7.3.4 TCP and TCP Pad

When the RLXIC-SG is in a TCP session, all characters received on the serial
port are assembled into TCP packets, and sent to the mode's remote IP
address/port, and any packets received from the remote end of the TCP
connection are disassembled, and dumped onto the serial line.

A TCP connection is established by one of the following methods:
 Using the Dial TCP (DT) AT command. For example,

ATDT192.168.3.23/3456.

 TCP auto answer is enabled (S1), a TCP connection request is received, and

the modem is not in a data session.

 Data is received on the serial port, and

o The Startup Mode Default (MD) is 4 (auto TCP)
o The remote TCP destination, as defined in S53, successfully responds to

the TCP connection request.

The value of S7 (TCP Connection Time-out) specifies the number of seconds to
wait, after initiating a TCP connection attempt, for a successful connection to be
established. If the connection has not been successfully established before the
time-out occurs, ERROR/BUSY is returned.

TCP packet assembly is affected by the values of S50 (PAD Forwarding Time­out) and S51 (PAD Forwarding Character). Data received in the serial buffer will
be transmitted when the idle inter-character time-out specified in S50 (in tenths of
seconds) occurs or when a character is received that matches S51 (if non-zero).

The TCP session will be terminated if no data is transmitted or received for the
time interval specified in TCPT and TCPS. TCPT is the number of minutes
(TCPS=0) or seconds (TCPS=1) used for this idle time-out.

Caution: TCPT should never be 0 when using the TCP mode. A broken TCP session can result in
the modem being left with a TCP Auto Answer

TCP auto answer (S0=1|2) also allows a TCP connection request to be
"answered" when the modem is idle, not in a data session. The TCP connection
request's destination port has to match the modem's device port.

Note: UDP auto answer may also be set simultaneously with TCP auto answer. Then, when in the
idle state, the modem will accept either a TCP connection request or UDP incoming packet, and
enter a TCP or UDP session as appropriate.

7.3.5 Hybrid Mode

Hybrid modes are supported mainly for legacy implementations. Some previous
hybrid modes (MD=5, 6) are no longer implemented as special, unique modes.
Now that UDP auto answer (UDP Half-open, S82=2) can be enabled in
conjunction with UDP PAD mode (MD3), effectively this is the same as MD5 and
MD6 previously accomplished. Setting MD5 and MD6 are still supported, but not
recommended.

7.4 Data Communication

Note: The RLXIC-SG forwards messages to and from the cellular network for only ONE device per
port. The RLXIC-SG is a one-to-one gateway, and does not have advanced routing features
required to do one-to-many routing.

The primary purpose of the RLXIC-SG is to forward data from a single device
connected to one of the ports to the cellular network, and, ultimately, under most
circumstances, to the Internet in a one-to-one gateway configuration.

When the RLXIC-SG obtains its IP address from your cellular provider, it also
obtains the network routing information necessary to forward messages to their
routers which can then forward on from there. The RLXIC-SG then acts as a
router for the device connected to it, forwarding to or from the cellular network.

Note: If you have a device connected to the serial port and the USB port, they will not be able to
communicate to each other. Each port is routed separately to the cellular network with one-to-one
routing for each.

7.4.1 Public and Private Mode

In Public Mode, the RLXIC-SG will pass the IP address assigned by the cellular
network to the device connected to its port. Public Mode is the default mode for
the RLXIC-SG.

If you need more control over which gateway address, device address, and
netmask that is given out by the internal DHCP server, you can use the private
host mode, *HOSTPRIVMODE, and set the internal network IP addresses. The
RLXIC-SG will use NAT to forward packets to the end device.

Tip: When using Public mode, ProSoft Technology recommends connecting the modem directly to
the computer or other end device. Using a hub or switch may prevent the RLXIC-SG from updating
the IP address of the end device when an IP address is received from the cellular network.

In AceManager, the Private mode settings are part of the PPP/Ethernet group.

Data Communication and Host Modes RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

 *HOSTPRIVMODE - Set to 1 to enable the explicit IP addresses.
 *HOSTPRIVIP - Set to the IP address you want the RLXIC-SG to give to your

device.

 DHCP network Mask - The subnet mask that is passed to the DHCP client

on the Host device.

 *HOSTPEERIP - Set to the IP address you want for the RLXIC-SG.
 *HOSTNETMASK - Set to the subnetmask, generally 255.255.255.0.

Tip: If you are using Private Mode (*HOSTPRIVMODE=1), you will need to make sure that
*HOSTPRIVIP and *HOSTPEERIP are on the same subnet. If the subnet mask is 255.255.255.0, it
is safe to use 192.168.x.y for each as long as the x is the same number (0 in the example screen
shot above), and the y is different (1 and 2 in the example), and between 0 and 254.
Note: Regardless if the RLXIC-SG is configured for Public Mode or Private Mode, the same IP
address will be given to all devices connected to any of the ports. While you can connect with each
to the cellular network and the Internet, you cannot use the RLXIC-SG as a hub or router to
communicate between them.

Internal DHCP Server

DHCP (Dynamic Host Configuration Protocol) has become a primary component
of today's network environments. DHCP allows one server to automatically and
dynamically allocate network IP addresses, and other network related settings
(such as subnet masks, routers, etc.) to each computer or device without the
need to set up each specifically or keep track of what addresses have already
been used.

In a default configuration, the RLXIC-SG acts as a DHCP host to any device
connected to its ports, providing that device with an IP address which can be
used to communicate on the Internet. In Public Mode, that will be the IP address
assigned by the cellular network. In Private Mode, that will be the IP address
defined in *HOSTPRIVIP.

1 When the RLXIC-SG registers on the cellular network, it is assigned an IP

address from your cellular provider, for example, 10.1.2.0.

2 Acting as a DHCP server, in Public Mode, when the RLXIC-SG receives a

DHCP request from an Ethernet device connected via USB, it hands off the
assigned address to the device, and sets up the default gateway address as

10.1.2.1. If the fourth octet is already a 1, it assigns 10.1.2.2 as the router
address.

3 The RLXIC-SG also sends a /24 netmask (255.255.255.0 by default), and

sets up a static route which maps 192.168.13.31 (or the address configured
with *HOSTPEERIP if it is changed) to 10.1.2.1 (or 10.1.2.2 if that was what
the gateway address was given as).

Tip: When PPPoE is used with the RLXIC-SG, DHCP is not needed. A tunnel is set up connecting
a device (such as your computer or a router) with the modem. The device will then simply use the
MAC address of the RLXIC-SG to send all outgoing packets.

RLXIC-SG ♦ Intelligent Cellular Data Communication and Host Modes
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

Additional Connected Networks

If you have a router connected to the RLXIC-SG with additional networks
configured behind that router, you can specify them in the PPP/Ethernet group of
AceManager. Configure the Network the Host Network Mask for up to two
additional networks.

7.4.2 Basic Routing

Expanding the capabilities of the RLXIC-SG, ALEOS features some basic routing
to connected computers and networks.

Port Forwarding

Any data coming in on the defined Public Port will be passed to the
corresponding Private Port connected to the physical interface specified and
using the host IP address.

Note: This feature can be used only in private mode.

In AceManager, enter the fields in the Port Forwarding group.
 Number of PF Entries: Set value to number of used Port forward rules for

performance gain. Each forwarding entry has four parameters:

o Public Port: Port number of the Modem/Gateway.
o Host/IF: Physical connection type to the modem. (USB, Ethernet, Serial).
o Host IP: IP address of the connected device/computer.
o Private Port: Port number on the connected device.

You can set a default in the PPP/Ethernet group, if you do not need:
 To forward to specific ports on your connected device, but you want all data

to be directly used by ALEOS, or otherwise forwarded.

 To pass to only one connected device.

Note: The default settings are independent of the number of Port Forward entries, and can be
used with port forwarding to pass anything not forwarded to specific ports.

o Default Interface: Choose the Default Interface desired (that is, Ethernet

or USB or Serial).

o Default IP: Enter this option only when you want to forward ports not

specified, to the default IP.

Firewall Functions

The RLXIC-SG can provide a basic firewall between the public and private
networks. There are two types of firewall rules supported by the RLXIC-SG, IP
filtering and port filtering.

 IP Filtering: When enabled, only packets with source IP addresses matching

those in a list or range of trusted hosts will be allowed through.

o Friends List IP: Each entry can be configured to allow a single IP address,

for example 64.100.100.2, or the IP addresses from a complete subnet,
such as 64.100.10.255 allowing all IP addresses from 64.100.10.0 to

64.100.10.255.

o Non-Friends Port Forwarding: Non-Friends port forwarding is like an allow

rule for any of the forwarded ports. If it is enabled, the port forwarding
rules apply to all incoming packets. If it is disabled, only Friends List IPs
get through.

o Start and End Range: Specify the IP address range that is allowed

access, for example 64.100.10.2 to start and 64.100.10.15 to end would
allow 64.100.10.5 but would not allow 64.100.10.16.

Data Communication and Host Modes RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

7.5 Keepalive

Keepalive is used to test the connection to the cellular network by pinging an IP
address after a specified period of inactivity. Keepalive is only recommended for
users who have a remote terminated modem that infrequently communicates to
the network or if you have experienced issues over time where the modem can
no longer be reached remotely.

When Keepalive pings the IP address, an acknowledgement indicates there is an
active connection to the network. If the RLXIC-SG does not receive a response
from the IP address, it will make additional attempts according to a backoff
algorithm before determining the Internet connection is not functioning properly. If
it determines the connection is not functioning, the modem will then attempt to
reconnect to your cellular provider to reestablish IP connectivity.

7.5.1 Configuring Keepalive

In AceManager, the Keepalive settings are part of the OTHER group.

 *IPPING sets the interval, in minutes, you want Keepalive to test the network

connection. To disable Keepalive, set *IPPING to 0 (default setting).

Note: The minimum time which can be set for Keepalive is fifteen minutes. If you set *IPPING for a
value less than the minimum, the minimum value will be set.

 *IPPINGADDR sets the IP address you want to use for the connection test.

Caution: If *IPPINGADDR is left blank or is set to an invalid IP address (example, an IP which is
unreachable or one which is not a valid IP address), modem performance will be adversely
affected.

7.5.2 Data usage using Keepalive

Keepalive is an optional feature. If you frequently pass data with your modem,
you most likely do not need to have Keepalive enabled. When using Keepalive,
be aware that a ping moves approximately 66 bytes of data over the network,
and is billable by your cellular provider. The following *IPPING settings will incur
approximate monthly data usage in addition to any other data usage:

If you have a fleet of RLXIC modems or even if you only have one, it can be
difficult to keep track of the current IP addresses, especially if the addresses are
not static but change every time the modems connect to Provider. If you need to
connect to a modem, or the device behind it, it is so much easier when you have
a domain name.

8.1.1 Reasons to contact the modem and/or the connected device:

 Requesting a location update from a delivery truck.
 Contacting a surveillance camera to download logs or survey a specific area.
 An oil derrick that needs to be triggered to begin pumping.
 Sending text to be displayed by a road sign.
 Updating the songs to be played on a juke box.
 Updating advertisements to be displayed in a cab.
 Remote access to a computer, a PLC, an RTU, or other system.
 Monitoring and troubleshooting the status of the modem itself without needing

to bring it in or go out to it.

A dynamic IP address is suitable for many Internet activities such as web
browsing, looking up data on another computer system, data only being sent out,
or data only being received after an initial request (also called Mobile Originated).
However, if you need to contact RLXIC-SG directly, a device connected to the
modem, or a host system using your RLXIC-SG (also called Mobile Terminated),
a dynamic IP will not give you a reliable address to contact (because it may have
changed since the last time it was assigned).

Domain names are often only connected to static IP addresses because of the
way most domain name (DNS) servers are set-up. Dynamic DNS servers require
notification of IP Address changes so they can update their DNS records, and
link a dynamic IP address to the correct name.

 Dynamic IP addresses are granted only when your RLXIC-SG is connected,

and can change each time the modem reconnects to the network.

 Static IP addresses are granted the same address every time your RLXIC-SG

is connected, and are not in use when your modem is not connected.

RLXIC-SG ♦ Intelligent Cellular IP Manager
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

Because many cellular providers, like wire-based ISPs, do not offer static IP
addresses or static address accounts cost a premium vs. dynamic accounts, IP
Manager works with a Dynamic DNS server to receive notification from RLXIC
modems to translate the modem's dynamic IP address to a fully qualified domain
name. Thus, you can contact your RLXIC-SG directly from the Internet using a
domain name.

8.2 Understanding Domain Names

A domain name is a name of a server or device on the Internet which is
associated with an IP address. Similar to how the street address of your house is
one way to contact you and your phone number is another, both the IP address
and the domain name can be used to contact a server or device on the Internet.
While contacting you at your house address or with your phone number employ
different methods, using a domain name instead of the IP address actually uses
the same method, just a word based name is commonly easier to remember for
most people than a string of numbers.

Understanding the parts of a domain name can help to understand how IP
Manager works, and what you need to be able to configure the modem. A fully
qualified domain name (FQDN) generally has several parts.

 Top Level Domain (TLD): The TLD is the ending suffix for a domain name

(.com, .net, .org, etc.)

 Country Code Top Level Domain (ccTLD): This suffix is often used after the

TLD for most countries except the US (.ca, .uk, .au, etc.)

 Domain name: This is the name registered with ICANN (Internet Corporation

for Assigned Names and Numbers) or the registry for a the country of the
ccTLD (that is, if a domain is part of the .ca TLD, it would be registered with
the Canadian domain registry). It is necessary to have a name registered
before it can be used.

 Sub-domain or server name: A domain name can have many sub-domain

or server names associated with it. Sub-domains need to be registered with
the domain, but do not need to be registered with ICANN or any other
registry. It is the responsibility of a domain to keep track of its own subs.

server123.example.com

 .com is the TLD


example is the domain (usually noted as example.com, because the domain is

specific to the TLD)

server123 is the subdomain or server name associated with the device,



computer, or modem registered with example.com.

server123.example.com.ca

This would be the same as above, but with the addition of the country code. In
this example, the country code (.ca) is for Canada.

IP Manager RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

Tip: A URL (Universal Resource Locator) is different from a domain name in that it also indicates
information on the protocol used by a web browser to contact that address, such as www.prosoft­technology.com. www.prosoft-technology.com is a fully qualified domain name, but the http://, the
protocol identifier, is what makes the whole thing a URL.

8.3 Dynamic Names

When an IP address is not expected to change, the DNS server can indicate to
all queries that the address can be cached and not looked up for a long period of
time. Dynamic DNS servers, conversely, have a short caching period for the
domain information to prevent other Internet sites or queries from using the old
information. Because the IP address of a modem with a dynamic account can
change frequently, if the old information was used (such as with a DNS server
which indicates the address can be cached for a long period of time) when the IP
address changed, the domain would no longer point to the new and correct IP
address of the modem.

If your RLXIC-SG is configured for Dynamic IP, when it first connects to the
Internet, it sends a IP change notification to IP Manager. IP Manager will
acknowledge the change, and update the Dynamic DNS server. The new IP
address will then be the address for your modem's configured name.

After your modem's IP address has been updated in IP Manager, it can be
contacted via name. If the IP address is needed, you can use the domain name
to determine the IP address.

Note: The fully qualified domain name of your RLXIC-SG will be a subdomain of the domain used
by the IP Manager server.

8.4 Using IP Manager with your RLXIC-SG

To allow your RadioLinx modem to be addressed by name, the modem needs to
have a minimum of three elements configured. You can also configure a second
dynamic server as a backup, secondary, or alternate server.

In AceManager, select D

RLXIC-SG ♦ Intelligent Cellular IP Manager
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

 *MODEMNAME : The name you want for the modem. There are some

restrictions listed below for the modem name.

 *DOMAIN : The domain name to be used by the modem. This is the domain

name of the server configured for *IPMANAGER1.

 *IPMANAGER1 : The IP address or domain name of the dynamic DNS

server which is running IP Manager.

 *IPMANAGER2 : The secondary server for the domain. While it is optional to

have two servers configured, it is highly recommended.

Tip: You can use a domain name instead of the IP address for your IP Manager servers if you
have DNS set up in your RLXIC-SG.

 *IPMGRUPDATE1 and *IPMGRUPDATE2: How often, in minutes, you want

the address sent to IP Manager. If this is set to zero, the modem will only
send an update if the IP address changes (example, if your RLXIC-SG is
reset or is assigned a different IP address).

 *IPMGRKEY1 and *IPMGRKEY2: User defined password key which is used

instead of RadioLinx secret key when using an IP Manager server other than
the one provided by ProSoft Technology.

Restrictions for Modem Name

For the Modem Name, you should use something which is unique but also easy
to remember. Your company name or the intended function of the modem are
recommended. If you have more than one modem, and want to name them the
same, you can append a number for each. Because it is an Internet domain
name, there are some restrictions for the name.

 Must begin with a letter or number
 Can include a hyphen (-)
 Cannot contain spaces
 Must be no longer than 20 characters total

8.4.1 Data Usage for IP Manager Server Updates

The IP Manager update is a small packet sent to the server with a response sent
back to the modem. If you have *IPMGRUPDATE1 or *IPMGRUPDATE2 set to
any number but zero, the modem will send the update not only when it receives a
new IP address but at the time interval as well. The data traffic could be billed by
your carrier.

Each update is a total of 68 bytes from the modem with a 50 byte total response
from the server for a round trip update of 118 bytes.

8.4.2 Eairlink.com

As a service, ProSoft Technology offers an IP Manager server, which can be
used for any RadioLinx Intelligent Cellular modem.

Note: The IP Manager service is currently not a guaranteed service, although every effort is made
to keep it operational 24/7.

 *DOMAIN : eairlink.com
 *IPMANAGER1 : edns2.eairlink.com
 *IPMANAGER2 : eairlink.com

Important: Because many modems use the IP Manager service, you must have a unique name for
your modem.

8.5 Understanding DNS

The RLXIC-SG has the ability to query DNS servers in order to translate domain
names into IP addresses. This allows you to use domain names in place of IP
addresses for most of the configuration options requiring IP addresses. This is
important if your RLXIC-SG will need to contact another modem or other device
that has a domain name but an unknown or dynamic IP address (such as
another remote RLXIC-SG using IP Manager).

8.5.1 Configuring DNS

Generally, when your RLXIC-SG receives its IP address from Provider as part of
the connection process, it will also receive the DNS servers to use for resolving
(or translating) names to IP addresses which it will automatically configure in the
modem settings. Unless your RLXIC-SG will be used on a network with other
modems or devices which have names internal to the local network or frequently
changing IP addresses, the DNS servers provided by Provider should be all you
need.

If the RLXIC-SG will be communicating with a device that has a domain name
but changes its IP address frequently (such as another RadioLinx modem using
IP Manager) or is on a network where devices are accessed by names rather
than IP addresses, you will want to put in an alternate DNS (*DNSUSER) where
that domain is updated, such as the IP Manager server the remote modem is
using or the listing of IP addresses to names is kept.

If you need to manually configure DNS, in AceManager, select DNS.

ProSoft Technology, Inc. Page 71 of 136
May 29, 2009

RLXIC-SG ♦ Intelligent Cellular IP Manager
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

 *DNSUPDATE - This command sets how often you want DNS Updates to be

requested. Otherwise the RLXIC-SG will only send updates when it is reset,
powered up, or the IP address is granted by network changes.

 Use Alternate DNS 2 - Set another DNS User.

Note: You can set up a second DNS User, if you have two DNS users.

 *DNS1 and *DNS2 - The primary and secondary DNS servers set by Provider

when your RLXIC-SG gets its IP address.

 *DNSUSER - Set this, if desired, to an additional DNS server to query first

before the primary or secondary (just as a hosts file is queried first on a
computer). If *DNSUSER is set to 0.0.0.0, it will be ignored.

8.5.2 The "PPP-Peer" Domain Name

The RLXIC-SG uses the unqualified domain name of "ppp-peer" when it is in
PPP or SLIP address mode to resolve the address of the device or computer
connected via PPP or SLIP address. If the RLXIC-SG is not in PPP or SLIP
address mode, "ppp-peer" will resolve to 0.0.0.0.

In This Chapter

 Modbus Overview..................................................................................73



Configuring the RLXIC-SG at the Polling Host for Modbus on UDP......75

 Configuring the Remote RLXIC-SGs for Modbus with UDP..................77

The RLXIC-SG supports Modbus ASCII, Modbus RTU, BSAP, and can also
emulate other protocols like DF1 or others using its Modbus Variable feature.

9.1 Modbus Overview

The Modbus Protocol, developed by Modicon in 1979, provides for client-server
(also referred to as master-slave) communications between intelligent devices.
As a de facto standard, it is the most widely used network protocol in the
industrial manufacturing environment to transfer discrete/analog I/O and register
data between control devices. Modbus, BSAP, and other Modbus variations are
often used in conjunction with telemetry devices.

Tip: This section is just a brief overview of Modbus. For more information, refer to your Modbus
equipment distributor or manufacturer or http://www.modbus.org.

9.1.1 Telemetry

Telemetry is an automated communications process by which data is collected
from instruments located at remote or inaccessible points, and transmitted to
receiving equipment for measurement, monitoring, display, and recording. Trans­mission of the information may be over physical pairs of wires,
telecommunication circuits, radios or satellite.

9.1.2 Remote Terminal Unit (RTU)

Modbus was originally designed to be used in a radio environment where
packets are broadcast from a central station (also called master or host) to a
group of remote units. Each remote unit, Remote Terminal Unit (RTU), has a
hexadecimal identification number (ID). The first part of the broadcast packet
contains an RTU ID which corresponds to the ID of one of the remote units. The
Modbus host looks for the ID, and sends to only the unit with the matching ID.
The RTU would then reply back to the central station.

The RTU connects to physical equipment such as switches, pumps, and other
devices, and monitors and controls these devices. The RTU can be part of a
network set up for Supervisory Control and Data Acquisition.

RLXIC-SG ♦ Intelligent Cellular Configuring Modbus/BSAP
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

9.1.3 Supervisory Control and Data Acquisition (SCADA)

Supervisory Control and Data Acquisition (SCADA) describes solutions across a
large variety of industries, and is used in industrial and engineering applications
to monitor and control distributed systems from a master location. SCADA
encompasses multiple RTUs, a central control room with a host computer (or
network), and some sort of communication infrastructure.

SCADA allows for "supervisory" control of remote devices as well as acquiring
data from the remote locations. Programmable Logic Controllers allow for a
higher degree of automated SCADA.

9.1.4 Programmable Logic Controller (PLC)

A Programmable Logic Controller (PLC) is a small industrial computer which
generally monitors several connected sensor inputs, and controls attached
devices (motor starters, solenoids, pilot lights/displays, speed drives, valves, etc.)
according to a user-created program stored in its memory. Containing inputs and
outputs similar to an RTU, PLCs are frequently used for typical relay control,
sophisticated motion control, process control, Distributed Control System, and
complex networking.

9.1.5 Modbus TCP/IP

Modbus TCP/IP simply takes the Modbus instruction set and wraps TCP/IP
around it. Because TCP/IP is the communications standard for the Internet and
most networked computers, this provides a simpler installation. Modbus TCP/IP
uses standard Ethernet equipment.

9.1.6 RLXIC Modbus on UDP

When RadioLinx modems are used in place of radios, one RLXIC-SG is
connected to the central station (host) and the other RLXIC-SG is connected to
each remote unit. When the RLXIC-SG is configured for Modbus with UDP, the
RLXIC-SG connected to the host can store a list of IP addresses or names with
matching IDs. When the host at the central station sends serial data as a poll
request, the RLXIC-SG at the host matches the RTU ID to a corresponding IP of
a RLXIC-SG at a remote unit. A UDP packet is assembled encapsulating the
RTU ID and serial data transmitted from the host. The UDP packet is then
transmitted to the specific RLXIC-SG at the remote unit matching the RTU ID.
The remote RLXIC-SG then disassembles the packet before transmitting the
RTU ID and serial data to the remote unit. The remote units operate in normal
UDP mode, and their data is sent to the host via the remote RLXIC-SG and host
RLXIC-SG.

9.2 Configuring the RLXIC-SG at the Polling Host for Modbus on UDP

This section covers a Polling Host with standard Modbus, variations may need
additional AT commands.

9.2.1 Configure the listening/device ports

In AceManager, select MISC in the side menu.

The destination port for the modem at the host needs to match the device port
(*DPORT) in use on all the modems at the remote sites. For example, if the
remote modem's device port (*DPORT) is "12345", then the Modbus host
modem's S53 destination port should be set to "12345".

Take note of (or set) the Device Port setting in *DPORT to configure the
destination port on the remote modems.

9.2.2 Configure the default mode for start-up.

In AceManager, select UDP in the side menu. Select the appropriate MD mode
from the drop down menu.

 MD13: Modbus ASCII
 MD23 : Modbus RTU (Binary)
 MD33: BSAP
 MD63: Variable Modbus - individual parameters are set up manually.

9.2.3 Configure IP addresses for the Modbus IDs.

The last step of configuring the modem at the host is setting the IDs to their
specific IPs. In AceManager, select the menu option A

DDR LIST.

Addresses can be entered in decimal or hex. AceManager will translate hex
entries into decimal. The number before the "=" is ID, the number after is the IP
address. There can be a total of 100 remote ID/Local addresses entered into the
modem.

When using AT commands via telnet or direct serial connection, use ATMLIST
for decimal IDs, and ATMLISTX for hexadecimal. For example, if the ID is 27,
and the IP is 123.123.123.124, you would enter it as
ATMLIST27=123.123.123.124 or ATMLISTX1B=123.123.123.124.

9.2.4 Optional: Dynamic IP Address

If you do not have a static IP, the host modem should be configured to report its
current IP to a Dynamic DNS (DDNS) server with IP Manager.

In the Host modem's configuration, instead of IP address for the Addr List
(ATMLIST or ATMLISTX), substitute a single unique name for each modem, that
is, remote1, remote2, etc.

When you configure IP Manager for the host modem, make note of your modem
name and domain setting in AceManager in the menu selection D
used with the remote modems.

Configuring Modbus/BSAP RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

With names instead of IP addresses for the Address List, the host modem will
query the DNS server for the current IP address assigned to the specific name of
a remote modem to send a message corresponding to the ID.

When you use names instead of IP addresses, to ensure your modems are
updated quickly with the correct IP addresses for the names, you will want to set
the DNS settings as well. In AceManager, select DNS.

Configure *DNSUSER to the same IP address as the IP Manager
(*IPMANAGER1). If your modems have dynamic IP addresses, and not static
(the IP address can change when it is powered up), configure *DNSUPDATE to a
low interval to allow frequent updates.

9.3 Configuring the Remote RLXIC-SGs for Modbus with UDP

This section covers standard Modbus settings for the RLXIC-SG at the remote
unit, variations may need additional commands.

9.3.1 Configure the ports

In AceManager, select MISC in the side menu.

ProSoft Technology, Inc. Page 77 of 136
May 29, 2009

RLXIC-SG ♦ Intelligent Cellular Configuring Modbus/BSAP
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

The destination port for the modem at the host needs to match the device port in
use on all the modems at the remote sites. For example, if the remote modem's
device port (see below) is "12345", then the Modbus host modem's S53
destination port should be set to "12345".

Set the destination port (S53) to match the device port of the host modem
(*DPORT). Make sure the device port of the remote modem (*DPORT) matches
the destination port of the host modem (S53).

9.3.2 Configure IP addresses for the host.

If the Host modem has a static IP address, enter it in the Destination Address for
S53.

Note: With a name instead of IPs for the host modem, the remote modems will query the DNS
server for the current IP assigned to the host modem before sending data back to the host.

If the modem at the host has a dynamic IP, and is using IP Manager, instead of
an IP address for S53, specify the name of the host modem (*MODEMNAME). If
the remote modems are using a different DDNS than the host modem, you will
need to specify the fully qualified domain name (*MODEMNAME+*DOMAIN).

Note: Setting the Host modem IP address as the S53 Destination Address provides a low level
security. The modem will not forward UDP traffic unless the source IP/port matches what is in S53.
However, if you set *AIP=1, the modem will forward UDP traffic from any source IP address as long
as it is accessing the modem on the configured *DPORT.

9.3.3 Configure the default mode for start-up.

Each modem at the remote locations will need to be configured to communicate
with the modem at the host. In AceManager, select UDP in the side menu.

1 Enable S82, UDP auto answer.
2 Set S83 to the idle time-out applicable to your application, commonly 20.

9.3.4 Configure other RTU settings.

Other parameters may need to be changed, but this is dependent on the RTU
type being used. As a minimum, this typically involves setting the proper serial
settings to match your RTU.

9.3.5 Optional: Dynamic IP Address

If you do not have a static IP, the host modem should be configured to report its
current IP to a Dynamic DNS (DDNS) server with IP Manager.

You will need to match the name of the modem to the names specified in the
host modem's MLIST or MLISTX for the connected RTU.

When you configure IP Manager for the host modem, make note of your modem
name and domain setting in AceManager in the menu selection D
used with the remote modems.

When you use names instead of IP addresses, to ensure your modems are
updated quickly with the correct IP addresses for the names, you will want to set
the DNS settings as well. In AceManager, select DNS.

Configure *DNSUSER to the same IP address as the IP Manager
(*IPMANAGER1). If your modems have dynamic IP addresses, and not static
(the IP address can change when it is powered up), configure *DNSUPDATE to a
low interval to allow frequent updates.

10 SNMP : Simple Network Management Protocol

In This Chapter

 SNMP Configuration..............................................................................82



SNMP MIB Definition Sample................................................................84

The Simple Network Management Protocol (SNMP) was designed to allow
remote management and monitoring of a variety of devices from a central
location. The SNMP management system is generally composed of agents (such
as your RLXIC-SG, a router, a UPS, a web server, a file server, or other
computer equipment), and a Network Management Station (NMS) which
monitors all the agents on a specific network. Using the management information
base (MIB), an NMS can include reporting, network topology mapping, tools to
allow traffic monitoring and trend analysis, and device monitoring.

Authentication ensures SNMP messages coming from the agent, such as the
RLXIC-SG, have not been modified, and the agent may not be queried by
unauthorized users. SNMPv3 uses a User-Based Security Model (USM) to
authenticate, and, if desired or supported, message encryption. USM uses a user
name and password specific to each device.

The RLXIC-SG can be configured as an SNMP agent, and supports SNMPv2c
and SNMPv3.

10.1.1 Management Information Base (MIB)

The management information base (MIB) is a type of database used to compile
the information from the various SNMP agents. Reports from various agents,
such as the RLXIC-SG, are sent as data in form designed to be parsed by the
NMS into its MIB. The data is hierarchical with entries addressed through object
identifiers.

10.1.2 SNMP Traps

SNMP traps are alerts that can be sent from the managed device to the Network
Management Station when an event happens. Your RLXIC-SG is capable of
sending the linkUp trap when the network connection becomes available.

ProSoft Technology, Inc. Page 81 of 136

RLXIC-SG ♦ Intelligent Cellular SNMP : Simple Network Management Protocol
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

10.2 SNMP Configuration

To configure your RLXIC-SG to work as an SNMP agent, you can use either
AceManager, or a terminal connection to configure the modem using AT
commands. In AceManager, the SNMP commands are all part of the Other
group under the Common group.

There are only three commands to set for SNMP in the RLXIC-SG: the listening
port, the security level, and the trap destination.

10.2.1 Listening Port

*SNMPPORT sets the port for the SNMP agent to listen on. If set to zero, default,
SNMP is disabled.

Tip: SNMP generally uses port 161, however most Internet providers (including cellular) block all
ports below 1024 as a security measure. You should be able to use a higher numbered port such
as 10161.

10.2.2 Security Level

*SNMPSECLVL sets the security level and which version of SNMP
communications are used.

 0 - No security required. SNMPv2c and SMNPv3 communications are

allowed.

 1 - Authentication required. SNMPv3 is required to do authentication, and

SNMPv2c transmissions will be silently discarded. Authentication is
equivalent to the authNoPriv setting in SNMPv3.

 2 - Authentication required, and messages are encrypted. SNMPv3 is

required to do authentication. SNMPv2c, and SNMPv3 authNoPriv
transmissions will be silently discarded. Authentication and encryption is
equivalent to the authPriv setting in SNMPv3.

User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

10.2.3 User Name and Password

The user name is "user". The user name cannot be changed. The RLXIC-SG's
password is used as the SNMP password (default is "12345").

To change the password in the RLXIC-SG, select Modem from the top menu line
in AceManager.

The current password will be pre-entered. As you type the new password and
confirm it, the characters you type will be obscured by "x". For the password, you
can use numbers, letters, and/or punctuation.

Caution: The password is case sensitive. "drowssaP" is not the same as "drowssap".

10.2.4 Trap Destination

*SNMPTRAPDEST needs to be set with the destination IP and port. If either are
set to zero or empty, SNMP traps are disabled.

Note: Traps are sent out according to the SNMP security level (that is, if the security level is 2,
traps will be authenticated and encrypted). Currently, the only trap supported is LinkUp.

10.2.5 Community String

The community string can be configured using *SNMPCOMMUNITY. The default
is "public".

The configuration commands (AT commands) in this chapter are arranged
according to their placement in AceManager.

Note: Some commands can only be configured using a terminal emulation and typed AT
commands. Some commands also require PassThru mode.
Tip: You can use a fully qualified domain name instead of an IP address for most configuration
options calling for an IP address if your RLXIC-SG is configured to use DNS. DNS settings
frequently come directly from your cellular provider while your RLXIC-SG is registering on the
cellular network, and receiving its IP address.

11.1 Info (information)

The commands in the "Info" group have read-only parameters. They only provide
information about the modem. Some of the information displayed in this group
does not correspond directly to AT commands.

*DEVICEID?

The 64-bit device ID the modem uses to identify itself to the cellular network.

11.2.2 AT Commands Requiring PassThru mode

These commands are not displayed in AceManager.

11.3 Common

The groups under the heading Common encompass those commands that are
common to most RadioLinx modems.

11.3.1 Misc (Miscellaneous)

The commands of the "Misc" group are a variety of commands that do not
directly fit in other categories.

Enable Event Reporting = n

Enable or disable Event Reporting, by selecting either 1-Turn on ER or 0-Turn off
ER. If you choose to enable, click on Write, and then Refresh all to see all the ER
fields.

 n=0 : Disables
 n=1 : Enables

+++

Note: +++ is not proceeded by AT nor does it require a carriage return (enter). There must be an
idle time (set by S50) on the serial port before and after this command.

AT Escape sequence. If the RLXIC-SG is in a data mode (any mode other than
PassThru), this command causes the modem to re-enter AT command mode.
The "+" is ASCII 0x2B.+++ is not available in AceManager.

RLXIC-SG ♦ Intelligent Cellular Configuration Commands
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

Tip: DAE=1 disables the +++ command.

A/

Note: A/ is not proceeded by AT.

Re-execute last command. A/ is not used in AceManager.

A
Manually answer an incoming connection. A is not used in AceManager.

D[method][d.d.d.d][/ppppp] or D[method][@name][/ppppp]

Dial a connection to a remote IP and Port using method. Cannot be configured in
AceManager.

 method=P : Establish a UDP connection
 method=T : Establish a TCP connection
 method=N : Establish a Telnet connection
 d.d.d.d= IP address to contact
 ppppp= port to contact

Examples:

ATD - Dial (establish) default connection.
ATDP192.168.13.31/2332 - Dial (establish) UDP session to 192.168.13.31, at

port 2332.

To end the connection, issue the +++ escape sequence or drop the DTR line (if
Ignore DTR S211=0 or &D2). The default connection is set in S53.

If the method, IP address, or port is omitted, the values from S53 are used. If a
telnet connection is requested (N), and the port is not supplied, port 23 will be
used instead of the value from S53.

If a domain name is specified, the "@" symbol can be used to explicitly indicate
the start of the name. For example, if ATDPHONY is issued, this will be
interpreted as dial a UDP connection to "HONY". To dial using the default
method to host "PHONY", one would issue ATD@PHONY.

Several special dialing numbers exist to make it easy to establish a PPP or SLIP
connection with the modem. ATD#19788 or ATDT#19788 will establish a PPP
connection (see \APPP) and ATDT#7547 will establish a SLIP connection (see
\ASLIP).

Tip: The source port of the session is the Device Port (set by S110 or *DPORT).

RLXIC-SG ♦ Intelligent Cellular Configuration Commands
RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM User Manual

Z

Reset the RLXIC-SG. In AceManager, this command is performed with the Reset
option on the toolbar.

Tip: *DATZ=1 will disable Z.

&W

Writes all changed modem settings. If this command is not issued, any modified
values will revert back to their previous values at modem reset. Cannot be
configured in AceManager.

*DATE=[mm/dd/yyyy],[hh:mm:ss]

Sets and queries the internal clock. Either the date and time can be specified, or
simply one of the two can be specified in which case the unspecified value will
remain unchanged. The date and time are always specified 24-hour notation.

 mm/dd/yyyy=date in month/day/year notation
 hh:mm:ss=time in 24-hour notation

*DPORT=n

The modem's Device Port which the modem is listening on for inbound
packets/data/polls. Can also be set with the command S110.

 n=1-65535

*HOSTPAP=n

Use PAP to request the user login and password during PPP negotiation on the
host connection.

Configuration Commands RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

*NETUID=uid

The login that is used to login to the cellular network, when required.
 uid=user id (up to 64 bytes)

*STATICIP=d.d.d.d

Set the static IP required to be received from the network. If the modem does not
get this IP address from the network, it will reset the internal hardware, and try
again. The default is 0.0.0.0, which allows any IP address from the network.

 d.d.d.d=IP address
Example:

AT*STATICIP=192.168.1.23

Caution: STATICIP does not set the IP address of the modem, it merely tells the modem which IP
address to expect. If the expected IP address is not granted while registering on the cellular
network, the modem will try to register on the network again until it receives that IP address. If your
account is set up for a dynamic IP address, and you set an address for *STATICIP, you may not be
able to register on the network at all because there is no guarantee you will receive the same
dynamic IP address again.

*STATUSCHK=n

Checks if an SMS message has been received by the modem.

 n=1-255 : Seconds between checks.
 n=0 : Never check.

11.3.2 Serial

This group includes commands specific to general use of the serial port.

Note: With more than one connection types (serial, and Telnet, and USB) the echo command can
be set differently on each interface. USB is only available on RLXIC Serial radios.

Qn

The AT quiet-mode setting. If quiet mode is set, there will be no responses to AT
commands except for data queried.

 n=0 : Off (Default).
 n=1 : Quiet-mode on.

S3=n

The standard end of line character used to indicate the end of an AT command.
This character is also used as the carriage return character for framing
responses and result codes in command state. Cannot be configured in
AceManager.

S4=n

The standard line feed character sent by the modem to the host at the end of a
response or return code in command state. Cannot be configured in
AceManager.

S5=n

This register sets the character recognized as a backspace during command
entry. Cannot be configured in AceManager.

S6=n

This register denotes the wait time, in seconds, before a blind dial (no dial tone
detection). Cannot be configured in AceManager.

S8=n

Whenever a dial command contains the comma character, the contents of this
register specify the pause time for each comma. Cannot be configured in
AceManager.

S9=n

Specifies the time that the received carrier must be present for the modem to
recognize it, and turn on Data Carrier Detect (DCD) if applicable. The
implementation is entirely at the IWF modem. Cannot be configured in
AceManager.

Page 98 of 136 ProSoft Technology, Inc.

May 29, 2009

Configuration Commands RLXIC-SG ♦ Intelligent Cellular
User Manual RadioLinx Intelligent Cellular Serial Modem for Global GPRS/GSM

S10=n

Specifies the amount of time that the carrier from the remote modem can be lost
before the modem goes on-hook. This allows temporary disruptions to carrier
without disconnecting. A setting of 255 causes the modem to disable Carrier
Detect, and presume carrier is always present. Cannot be configured in
AceManager.

S23=[speed],[databits][parity][stop bits]

Serial line parameters. The settings take affect after reset.
 speed=300 | 1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600 | 115200 |

230400

 databits=7 or 8 (Databits MUST be 8 data bits for PPP mode.)
 parity=O : Odd
 parity=E : Even
 parity=N : None
 parity=M : Mark
 stopbits=1 | 1.5 | 2

Example:

ATS23=19200,8N1

Sets modem to 19200, 8 databits, no parity, and 1 stop bit.

Tip: Can also be set using &L=[speed],[databits] [parity][stop bits]

S50=n

Data forwarding idle time-out. If set to 0, a forwarding time-out of 10ms is used.
Used in UDP or TCP PAD mode.

 n=tenths of a second

S51=n

PAD data forwarding character. ASCII code of character that will cause data to
be forwarded. Used in UDP or TCP PAD mode.

 n=0 : No forwarding character.

S211=n

For applications or situations where hardware control of the DTR signal is not
possible, the modem can be configured to ignore DTR. When Ignore DTR is
enabled, the modem operates as if the DTR signal is always asserted.

 n=0 : Use hardware DTR. (default).
 n=1 : Ignore DTR.
 n=3 : Ignore DTR, and assert DSR. This value is deprecated, and it is

recommended to use &S to control the DSR instead. When this value is set to
3, &S will automatically be set to 0. See also: &D and &S.

ProSoft Technology, Inc. Page 99 of 136
