1.2. Operating Instructions
The modem can interfere with electronic devices; therefore there are the following limitations on its use:
Power off the modem in medical centres and keep it away from medical equipment (for example, cardiac
pacemakers, and hearing aids).
Power off the router in aircraft, take measures against accidental switch-on.
Power off the modem near gas stations, enterprises of chemical industry, in areas where blasting opera-
tions are in progress.
At close range the modem can interfere with television and radioreceiver operation.
To ensure safe operation, follow the recommendations:
6
Do not expose the modem to aggressive influences (high temperatures, corrosive chemicals, dust, water,
etc.).
Protect the modem from impacts, falls and excessive vibration.
Do not attempt to disassemble or modify the modem. Such actions will void the warranty.
Note! Use the device in compliance with the operating instructions. Damages caused by improper use
and storage of the device are not covered by the warranty.
1.3. Terms and Definitions
Local configuration or updating firmware –configuration or updating of the modem firmware connected to
a computer via a USB cable. For the ATM modem they are performed via the ATM Control program.
Remote configuration or updating firmware –configuration or updating of the modem firmware located on
the site, from the dispatching center. For the ATM modem they are performed via the iRZ Collector dispatching
application, which is used together with the iRZ Collector server application.
Modem-client –the ATM modem operating in the TCP/IP client mode, i.e. the modem is connected to the
data collection server and transmits it data from an external device.
Server modem –the ATM modem operating in the server mode, i.e. the modem waits for incoming connec-
tions and processes them.
The system of data collection and device control (hereinafter referred to as system) –a set of tools for
automated data collection from external devices, located on sites, and their control as well as its processing,
accumulation and transmission.
Server –a computer or specialized computer equipment with the installed server software for processing cli-
ent requests (in the terms of a client-server interaction model).
iRZ Collector solution –iRZ-manufactured software solution including the server and the dispatching appli-
cations of iRZ Collector.
iRZ Collector server application –the iRZ Collector server software to be installed on a data collection
server. It enables a third-party polling software, acting as a client (in the terms of a client-server interaction
model), to receive data from the modems, which also act as clients. That is, the server application serves as a
kind of "layer" enabling their interaction (see Fig. 1.1). For ease of reference, hereinafter the server with the in-
stalled iRZ Collector server application is referred as the iRZ Collector server.
When ATM operates in server mode, it receives connections on its own –it no longer requires a broker to in-
teract with the polling software, operating in a client mode. In this case the iRZ Collector solution can be still
used to monitor and control the system modems (see Fig. 1.2).

mode
Fig. 1.2 Interaction diagram when using the iRZ Collector software solution –the modem operates in a server
mode
The iRZ Collector dispatching application –the iRZ Collector dispatching software which operates to-
gether with the iRZ Collector server application and enables remote monitoring and control of the system mo-
dems. It can be used in the dispatching center or data collection server as well as in any computer with the op-
erating system supporting the application.
External devices polling software is used in the dispatching center to poll external devices and is provided
by their manufacturer. Generally, it operates in the client mode, and therefore the following two main methods
are used to interact with the modem: First –the modem operates in the client mode, and a special-purpose
"layer" (for example, the iRZ Collector server application) is used to interact with it. Second –the modem oper-
ates in the server mode that enables a third-party software to connect it directly. However in the second case
each modem requires an external
1
static IP address.
1
If your company rents an access point (APN) from a mobile network carrier, the modem will use an internal static ad-
dress.
8
Dispatching center –data collection and dispatching center intended to poll external devices, installed on
sites, and to monitor and control the system modems.
Data collection server
1
–the server where all the system data is accumulated and processed: data from ex-
ternal devices and system's service information. The modem-clients are connected to the data collection server
and transmit the required data, the external device polling software is also connected to the server and re-
quests the data received by the server from the modem.
External device –the device mounted on a site and connected to the modem via the RS232 communica-
tions interface. Heat and energy meters, as well as any systems of telemetry and telemechanics, may operate
as external devices.
SMS command –an SMS message sent to the modem, containing a character-based command of a certain
format.
2. Product Overview
2.1. Product Purpose and Main Functions
The iRZ ATM 3G communicator provides data transmission via TCP/IP protocol stack. The device is de-
signed for operation in telemetry systems.
The modem can operate in any of the three modes: client, server or CSD only In the Client mode (hereinaf-
ter –client modem) the modem is connected to the data collection server and transmits data from an external
device. In the Server mode (hereinafter –modem server), the modem, on the contrary, waits for the client in-
coming connection (for example, from a dispatcher computer) on a certain port and processes it. In the CSD
Only mode data is transmitted via CSD (voice channel) with no data transmission over network and the offline
mode available.
For operation in the Client mode you can use any SIM card, for operation in the Server mode it is recom-
mended to use a SIM card with an external
2
static IP address. For operation in the CSD only mode you can
use any CSD-enabled SIM card.
In the Client and Server modes the modem automatically connects to the network. After that the modem es-
tablishes connection to the specified server (if operating in the client mode) or opens an incoming port and
waits for incoming connections (if operating in the server mode).
1
2 Used if the modem and the external devices polling software operate as clients. If the modem operates in the server
mode, the software can be connected to it directly and read out the required data.
2
If your company rents an access point (APN) from a mobile network carrier, addresses of the sites for such network will
be internal. In this case it is recommended to use a private static address.
9
The device provides transparent communication between a third-party external devices polling software and
an external device connected to the modem via RS232 interface. The modem tracks the internet connection
status and in case of connection loss, the modem restores it (see section "Device Operating Procedure".).
The ATM modem supports the use of two SIM cards providing backup mobile access (see section "Working
with SIM Cards").
The client mode supports backup Internet connection –the main server switches to a backup server in case
of disconnection. Switching between servers is also possible with a signal from the modem GPIO pins (see
section "Working with the Server").
The client modem can operate with a standard server (see section "Working with the Server") or a special-
purpose iRZ Collector server. The iRZ Collector server provides transparent data communication between a
third-party polling software, operating as a client, and the modems which also operate as clients and do not
have static IP addresses (see section "Working with the iRZ Collector Server").
The modem supports data transmission via CSD (voice channel). If there is phone number group enabled in
the modem settings, data transmission over CSD is available in the client and server mode. In addition, ATM
supports a separate mode for data transmission only over CSD.
The modem has additional pins (GPIO) to monitor and control external devices (see section "GPIO Pins Op-
eration"). ATM can send SMS messages at change of pin signal strength enabling remote control of external
devices connected to the modem. The pins state can be changed sending SMS command to the modem ena-
bling remote control of external devices.
The modem features the offline mode supporting all functions except network connection (see section
"Offline Mode"). Offline mode provides economy of traffic and power consumption. It is used if there is no need
for continuous connection.
ATM tracks the 3G module hangup and provides its additional restart by a signal from the configurable
watchdog timer (see section "Watchdog Timers"). GSM module rebooting can be initiated with a phone call
from a group of numbers, specified in ATM Control application (Settings → Advanced→ WDT → Phone No.
for rebooting the module), as well as with the SMS command "XXXX reboot", where XXXX is the access
code for service mode (5492 by default). The modem provides operation within a wide range of input voltages
and temperatures.
During its operation the modem displays messages in the log via USB interface in a real time. To view and
analyze the log on a computer, use any terminal program (see section "Main Log Messages").

2.10. Interfaces
The device is equipped with two serial interfaces: Mini USB and RS232 as well as the GPIO programmable
interface.
2.10.1. Mini USB Connector
The mini USB interface is used to set up the modem and log its operation (log removal). For operation of the
modem via Mini USB, it is required to install the USB driver which can be downloaded from the official website
of the Radiofid System Company (www.radiofid.ru) in "Support" section). The computer determines the modem
as a virtual COM port. The modem is powered via Mini USB interface only for operation in the service mode.
Fig. 2.4 Mini USB Connector
Note 1 USB is used in the "device" mode, therefore it can be used only for connection to a computer or
other host controller.
Note 2 With a terminal program, for example, Hyper Terminal, close a COM port in this program before
you connect a USB cable. You can open a COM port after connecting a USB cable.
2.10.2. DB9 Connector (RS232)
The connector is used to connect the modem to an external device with the RS232 interface (COM port).
Port factory settings: baud rate –9600, data bits –8, parity –not used, stop bits –1. All the parameters of the
operating COM port are changed in the service mode.

Note! The RS232 (COM port) standard does not allow hot plugging. To prevent damage to the COM port,
wait at least 5 seconds to plug and unplug connected devices after turning off the power.
The DCD, DSR, CTS, RING pins can be set to a high or low state in the encapsulation mode (see section
"Encapsulation Mode") or in the service mode using the ATM Control application. By default, the DCD, DSR,
CTS pins are set to a high state, RING –to a low state.
The modem supports operation with the COM port via the Modbus protocol. There are two protocol imple-
mentations available –Modbus RTU and Modbus ASCII.
Modbus RTU –the packet data protocol used for communication with external devices via RS232, RS485
and RS422. When operating in the GPRS network, overload of base stations might cause data link failure. The
17
modem operating with Modbus RTU prevents data link failure (over 1.5 times character length), i.e. the modem
task is to transmit a single data packet over the RS232/RS422/RS485 interfaces. The Pause option allows the
user to manually set the time interval of data absence, which will enable the modem to identify the end of data
package. Foremost, the Modbus RTU protocol is to be used if an external device operation is based on it.
Specify the Modbus ASCII protocol in the modem settings only if it is recommended to use this protocol by
the manufacturer of the external device.

2.11. The Modem Status Indication
To display the modem operation status, it is equipped with LED indication. The LEDs are placed above the
SIM card trays.
When you turn on the modem, both LEDs light up for 300 mc. In case of the RTC-timer failure, LEDs can
light up for 10 seconds while RTC is being initialized.
At the modem operation the indication is performed via the LED placed above the tray with an active SIM
card (a SIM card operating at a given moment is called active, the second one –inactive). LED signal interpre-
tation is shown in 2.4.

2.11.1. Signal Strength Indicators
The ATM modem is equipped with the
1
hard reset button which also designed for measuring the signal
strength of the modem. This feature allows you to find an optimal place to mount the modem antenna on a site.
Signal strength is displayed in the log and indicated by the LED for each SIM card of the modem.
To determine the signal strength, press the button using a thin object and release it. The LEDs indicate the
signal strength within a minute, after that the modem returns to the previous operation mode. With GPRS, 3G
or CSD connection established, the connection is terminated by pressing the button, and after the end of signal
verification it is re-established. Signal detection is not supported in the service mode.
When pressing the button, both LEDs light up for 2 sec, after the pause of one second active SIM LED starts
to blink in accordance with a signal strength of its SIM card (only if modem is registered in GSM nerwork).
Depending on the CSQ signal strength, the LED of each SIM card blinks certain times:
signal strength is below 9 –1 time;
signal strength is from 9 to 15 –2 times;
signal strength is from 16 to 19 –3 times;
signal strength is from 20 to 24 –4 times;
signal strength is above 24 –5 times;
Each LED blinking lasts for 80 / 400 ms: 80 ms –LED is on, 400 ms –LED is off. The pause of 4 seconds is
followed by LED blinking of certain number of times. After that the modem detects signal level and the process
is repeated –the LED blinks the number of times corresponding to the CSQ signal strength, then follows a four-
second pause –and so until a minute passes from the time the button has been pressed (see the sample in
Fig. 2.8).

be used for the modem authentication on a standard server (not iRZ Collector) if IMEI-based authentica-
tion is not sufficient. In addition, it can be used for iRZ protocol-based authentication (for more details, re-
fer to section "Authentication of Connecting Clients"). By default the modem login is equal to the modem
IMEI value.
SIM Cards Key Attributes
1. Mobile network carrier settings:
APN (Internet access point name);
Login (user name);
Password.
Request for network settings at the mobile operator of your SIM card.
2. PIN code (required if PIN code request is activated on the SIM card)
Key Attributes (for the modem-client operation)
1. Server IP address –the server IP address to which the modem-client is to be connected and transmit data
from an external device. It is required to specify a public static IP address of the data collection server or
network gateway (if the data collection server is in the local network behind the gateway). In the latter
case it is required to set up port forwarding from the gateway IP port to the server data collection IP port. If
you rent an APN from a service provider, it is required to specify the private address of the data collection
server in the IP address field. The address is 4 bytes long, consists of four decimal numbers, each ranging
from 0 to 255, separated by dots. For example, 83.58.124.13
2. Server port is a network port of data collection server where it waits for connection of client modems. Val-
ue –0 to 65000. This port should not be used by other services. If data collection server is located in the
local network behind network gateway, it is required to set up port forwarding from the gateway IP port to
the IP port of the server data collection.
If you plan to use the backup server, it is required to enter its IP address and port and authorize its use.
Key Attributes (for the server modem operation)
1. Incoming port is a network port of the modem-server where it waits for connection of clients. Value –0 to
65000. This port should not be used by other services.
