1. SAFETY INSTRUCTION
1. Safety instruction
Please, observe the following instructions:
•The router must be used in compliance with all applicable international and national laws
and in compliance with any special restrictions regulating the utilization of the router in
prescribed applications and environments.
•To prevent possible injury to health and damage to appliances and to ensure that all
the relevant provisions have been complied with, use only the original accessories.
Unauthorised modifications or utilization of accessories that have not been approved
may result in damage to the router and in a breach of applicable regulations. Unautho-
rized modifications or utilization of accessories that have not been approved may result
in the termination of the validity of the guarantee.
•The router can not be opened.
•Before handling of the SIM card turn off the router and disconnect it from power supply.
•Caution! The SIM card could be swallowed by small children.
•It must not be exceeded by the maximum voltage 30 V DC power connector on the router.
•Do not expose the router to extreme ambient conditions. Protect the router against dust,
moisture and high temperature.
•The router should not be used at petrol stations of flammable and explosive materials.
We remind the users of the duty to observe the restrictions concerning the utilization
of radio devices at petrol stations, in chemical plants, or in the course of blasting works
in which explosives are used.
•Switch off the router when travelling by plane. Utilization of the router in a plane may
endanger the operation of the plane or interfere with the mobile telephone network, and
may be unlawful. Failure to observe these instructions may result in the suspension
or cancellation of telephone services for the respective client, or, it may result in legal
sanctions; it may also result in both eventualities.
•When using the router in the close proximity of personal medical devices, such as cardiac
pacemakers or hearing aids, you must proceed with heightened caution.
•If it is in the proximity of TV sets, radio receivers and personal computers, the telephone
may cause interference.
•It is recommended that you should create an appropriate copy or backup of all the im-
portant settings that are stored in the memory of the device.

3. ROUTER DESCRIPTION
3. Router description
LTE router LR77 v2 Libratum is used to wireless connect various equipments and devices
via Ethernet interface 10/100 to the internet or intranet. Due to the high data transfer speed of
up to 14.4 Mbit/s (download) and up to 5.76 Mbit/s (upload) is this router an ideal wireless so-
lution for traffic and security camera systems, individual computers, LAN networks, automatic
teller machines (ATM) and other self-service terminals, etc.
As a standard, LR77 v2 Libratum wireless router is equipped with two Ethernet 10/100 and
two SIM card holders. This wireless router is supplied either in a plastic or metal casing, based
on the requirements of the customer.
Configuration is done via web interface protected by password. LR77 v2 Libratum sup-
ports creation of VPN tunnels using technologies IPsec, OpenVPN and L2TP to ensure safe
communication. Web interface provides detail statistics about the 3G router activities, signal
strength, detailed log, etc. Cellular router supports functions: DHCP, NAT, NAT-T, DynDNS,
NTP, VRRP, control by SMS and many other function.
Other diagnostic functions ensuring continuous communication include automatic inspec-
tion of PPP connection offering an automatic restart feature – in case of connection losses, or
hardware watchdog which monitors the status of the router. With the help of a special window
(start up script window) you may insert Linux scripts for various actions. For some applica-
tions the key option to create several different configurations for one LTE wireless router, the
so-called profiles (maximum of 4), and the option to switch between them (for example via
SMS, binary input status, etc.) is essential. Cellular wireless routers LR77 v2 Libratum may
automatically upgrade configuration and firmware from server. This allows mass reconfigura-
tion of many routers in one time.
For easy use additional software may be used – communication VPN server Digicluster
and software for router monitoring R-SeeNet.
Examples of possible applications
•mobile office
•fleet management
•security system
•telematic
•telemetric
•remote monitoring
•vending and dispatcher machines

5.6 Mechanical dimensions and mounting recommendations
Mounting recommendations:
•possibility to be put on a work surface,
•DIN rail with clips CKD2 (ELPAC clip SL for metal version) are included.
For the most of applications with a built-in router in a switch board it is possible to recognize
two kinds of environments:
•no public and industry environment of low voltage with high interference,
•public environment of low voltage without high interference.
For both of these environments it is possible to mount router to a switch board, the following
there is no need to have examination immunity or issues in connection with EMC according to
EN 60439-1 ed.2:00 + A1:04.
For compliance of EN 60439-1 ed.2:00 + A1:04 specification it is necessary to observe next
assembly of the router to the switch – board:
•for whip antennas we recommend to observe a distance of 6 cm from cables and metal
surfaces on every side according to the next picture due to the elimination of interfer-
ence, while using an external antenna except for the switch-board it is necessary to fit a
lightening conductor,
•before mounting a router on sheet-steel we recommend using an external antenna,
Figure 9: Space around antennas Figure 10: Space around antennas for SL

5. ROUTER DESIGN
•For every cables we recommend to bind the bunch according to the following picture, we
recommend for this use:
–Length of the bunch (combination of power supply and data cables) can be max-
imum 1.5 m. If the length of data cables exceeds 1.5 m or in the event of, the
cable leads towards the switch – board. We recommend installing over – voltage
protectors (surge suppressors).
–With data cables they mustn’t carry cables with reticular tension ∼230 V/50 Hz.
–All signals to sensors must be twisted pairs.
Figure 11: Cable routing Figure 12: Cable routing for SL version
•Sufficient space must be left before individual connectors for handling of cables,
Figure 13: Space in front of connectors Figure 14: Space in front of connectors – SL
•For correct function of the router we recommend to use in the switch-board earth-bonding
distribution frame for grounding of power supply of router, data cables and antenna.

5.7 Removing from the DIN rail
Default position of CPD2 holder (or CKD2 holder for SL version), which is used for mount-
ing the router on a DIN rail, is shown in the following figure:
Figure 15: Default position of DIN holder
For removing from the DIN rail it is necessary to lightly push upward the router so that the
top part of the CPD2 holder (or CKD2 for SL version) hitched to the DIN rail get out of this rail
and then fold out the top part of the router away from the DIN rail.

5.8.2 Power connector PWR
Panel socket 2-pin.
Pin number Signal mark Description
1 VCC(+) Positive pole of DC supply voltage (+10 to +30 V DC)
2 GND(-) Negative pole of DC supply voltage
Table 5: Connection of power connector
Figure 19: Power connector
Power supply for router is required between +10 V to +30 V DC supply. Protection against
reversed polarity without signaling is built into the router.
The power consumption during receiving is 2.3 W. The peak power consumption during
data sending is 5.5 W. However, values of consumption can be increased, if some expansion
port is eqquipped. For correct operation it is necessary that the power source is able to supply
a peak current of 1 A.
Connector on the power cable connects into the power connector on the router head and
tightens locking screws (see figure below).

5.8.3 Antenna connector ANT, DIV (and WIFI)
Main and diversity antennas are connected to the router using the SMA connector on the
front panel. For LR77 v2 Libratum with WIFI module is also available reverse SMA antenna
connector, through which the WIFI antenna can be connected.
The router can not operate without the main antenna connected labeled as ANT.
ANT connector is used to connect the main antenna router. To connect the diversity an-
tenna is used the second antenna connector DIV. In version with WIFI module is also available
WIFI connector used for antenna, which is intended to communicate via WIFI.
Example of antenna:
Figure 22: External antenna
For connection the antenna is used SMA connector. The antenna is connected by screwing
this antenna to the SMA connector on the front panel of the router (see figure below).
Figure 23: Connecting of the antenna
Diversity antenna improves radio features of the router at low signal strength.
