1.3. Terms and abbreviations
Router - iRZ RUH2b Router;
3G – a general description of a set standards describing the work in UMTS and GSM networks: GPRS,
EDGE, HSPA;
Server – this term can be used to mean:
a server part of a software package used in a computing complex;
roles of a component or an object in a structurally functional technical solution diagram being deployed
using the router;
a computer providing certain services (network services, data processing and storage, etc.);
Technical solution – an idea or a document describing a set of technical measures and/or activities to
perform a specific task that requires functionality of components used in this solution, which are interconnected
and interacting in a certain way;
External IP address – an Internet IP address assigned by an internet connection provider to customers for
use on their equipment to ensure the possibility of a direct communication with customers’ equipment via the
Internet;
Static external IP address – an external IP address, which may not change in any circumstances
(changing a customer's equipment type, etc. ) or events (reconnection to a network service provider, etc.); the
only possibility to change a static IP address is by sending an application to the service provider;
Authentication – a procedure for authentication of a user/customer/node by comparing their details with
the respective details of this user name/login in the database at the time of the connection;
Router web-interface router – a management tool built into the Router that provides a possibility to control
and customize its functions, and to monitor the status of these functions;
Remote device (remote site) – a device, geographically remote from a particular place, or object/node.

2. Device information
2.1. Purpose
A router is a multidisciplinary radio-technical subscriber device that works in cellular GSM/UMTS networks.
Router allows solving challenges of data transfer, reception, protection, and computer network support.
2.2. Communications standards
HSPA (speed: data transfer - up to 5.76 Mbps, reception - up to 7.2 Mbps);
EDGE;
GPRS;
USSD;
SMS;
Wi-Fi (optional, by using an external adapter).
2.3. Hardware specifications
Table 2.1: Key features
Type Feature
Processor ARM920T
Dynamic RAM 64 MB
Flash memory capacity 8 MB + possibility to expand to up to 2 GB
Ethernet connector 10/100Mbit, 100BASE-TX, MDI
COM connector RS232 (TX, RX, GND); RS485
USB connector USB 1.1

2.4. Compliance with the standards
Table 2.2: Standards
Standard Description
Ethernet (IEEE 802.x)*
The hardware that provides the router operation in Ethernet computer networks, designed
in accordance with the recommendations of the international standard IEEE 802.
RS232 / RS485 (EIA-232 / EIA-485)*
The interface used in routers to transfer user data designed in accordance with the
standard RS232 / RS485 recommended by the International Association of the Electronics
Industry - EIA.
USB*
Universal Serial Bus interface (the current version - USB 1.1) designed primarily to connect
a USB drive to the router. This allows to increase the volume of serviceinformation
registered by the router during operation (the system log, Status and log àSystem Log ).
It can also be used to enhance the router functionality by connecting to the USB port
adapters USB-Ethernet, and USB-COM.
* radio-technical implementation of the Ethernet interfaces, RS232 / RS485 and USB was implemented on the basis of Atmel micro
controller (series 9200)

sinusoidal vibration as per GOST 30631-99; the vibration frequency of 80 Hz should not be exceeded for the
equipment operating in motion, installed on tractors, track machines and on water transport (speed boats,
hydrofoil boats, etc.), and on technological equipment and ground transport.
Vibration insulation elements are not available.
2.7. Electrical characteristics
Power supply specifications:
power supply voltage from 8 to 30 V (DC);
maximum current consumption:
at the power voltage +12 V - 800mA;

Restrictions on the use of the device near other electronic devices:
Turn off the router in hospitals or when located near medical equipment (for example: pacemakers and
hearing aids); interference with medical equipment may occur;
The router off when on an airplane. Take measures against accidental turning on;
Turn the router off in the vicinity of gas stations, chemical plants, and places where demolition work is
conducted. May interfere with technical devices; at a close range, the router can produce interference
for television sets and radio transmitters
Protect the router against dust and water.
Please comply with the allowable power and vibration requirements at the device installation location.
