Unauthorised modifications or utilization of accessories that have not been approved
may res u lt in damage to the router and in a breach of applicable reg ul a ti o ns . Unautho-
rized modifications or utilization of accessories that have not been approved may re sul t
in the t e r m i n a t i o n of the v a l i d i t y 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 b y small children.
•It must not be e x c e e d e d b y the maximum v o l t a g e 30 V DC power connector on the router.

moisture and high t e m p e r a t u r e .
•The router should not be used at petrol stations of flammable and e x p l o s i v e materials.
W e remi n d the users of the duty to observe the res t ri cti ons concerning the utilization
of radio devices at petrol stations, in chemical plants, or in the course of blasting w o r k s
in which e x p l o s i v e s are used.
•Switch off the router when travelling b y plane. Utilization of the router in a plane may
endanger the operation of the plane or interfere with the mobile t e l e p h o n e network, and
may be unlawful. F a i l u r e to observe these instructions may re su l t in the suspension
or cancellation of t e l e p h o n e services for the re s pe cti ve client, or, it may resu l t in legal
sanctions; it may also res u lt in both e v e n t u a l i t i e s .
•When using the router in the close proximity of personal medical devices, such as cardiac
pacemakers or hearing aids, y o u must proceed with heightened caution.

3. R O U T E R DESCRIPTION
3. R o u t e r description
L T E router LR77 v2 is used to wirelessly connect v a r i o u s equipments and devices via
Ethernet interface 10/100 to the Internet or intranet. Thanks to high data transfer speed of
up to 100 Mbit/s (download) and upload speed up to 50 Mbit/s it is an ideal wireless solution
fo r traffic and security camera systems, individual computers, LANnetworks, automatic t e l l e r
machines (ATM) and o t h e r self-service t e r m i n a l s , etc.
As a standard, this e x c e p t i o n a l l y fast L T E LR77 v2 wireless router is equipped with one
Ethernet 10/100, one USB Host port, one binary Input/output (I/O) port and one SIM card
T o save and backup communication data a v e r s i o n with two SIM cards is a v a i l a b l e . The wide
range of interface options of the router further e x p a n d s P o r t 1 and P o r t 2 e x p a n s i o n ports, which
are selected b y the customer. F o r P o r t 1 are a v a i l a b l e : Ethernet port 10/100, serial interface
ports RS232/RS485/RS422/MBUS or inputs/outputs (I/O – CNT). P o r t 2 may be equipped with
serial interfaces RS232/RS485/RS422/MBUS, wireless interfaces WIFI/WMBUS, SDH e x p a n -
sion port or inputs/outputs (I/O – CNT). Both of ports can be fitted with internal switch (exp.
port S W I T C H ) . This 3G wireless router is supplied either in a plastic or metal casing, based
on the re q ui r e me n ts of the customer.
Configuration is done via w e b interface protected b y password. The LR77 v2 router sup-
ports creation of VPN tunnels using t e c h n o l o g i e s IPsec, OpenVPN and L2TP to ensure safe
communication. W e b 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 b y SMS and many o t h e r function.
Other diagnostic functions ensuring continuous communication include automatic inspec-
tion of PPP connection offering an automatic re st ar t f e a t u r e – in case of connection losses, or
hardware w a t c h d o g which monitors the status of the router. With the help of a special window
(start up script window) y o u may insert Linux scripts for v a r i o u s actions. F o r some applica-
tions the k e y option to create several different configurations for one L T E wireless router, the
so-called profiles (maximum of 4), and the option to switch between them (for e x a m p l e via
SMS, binary input status, etc.) is essential. Cellular wireless routers LR77 v2 may automat-
ically upgrade configuration and firmware from server. This allows mass re co n fig u rat ion of
many routers in one time.
F o r easy use additional software may be used - communication VPN server Digicluster
and software fo r router monitoring R - S e e N e t .

Mounting rec o mm e nd a ti o ns :
•possibility to be put on a w o r k surface,
•DIN rail with clips CKD2 (ELPAC clip SL for metal v e r s i o n ) are included.
F o r the most of applications with a built-in router in a switch board it is possible to re cog niz e
two kinds of environments:
•no public and industry environment of low v o l t a g e with high interference,
•public environment of low v o l t a g e without high interference.
F o r both of these environments it is possible to mount router to a switch board, the following
there is no need to have e x a m i n a t i o n immunity or issues in connection with EMC according to
EN 60439-1 ed.2:00 + A1:04.
F o r compliance of EN 60439-1 ed.2:00 + A1:04 specification it is necessary t o observe next
assembly of the router to the switch – board:
•fo r whip antennas w e re c om m en d t o observe a distance of 6 cm from cables and metal
surfaces on e v e r y side according to the next picture due to the elimination of interfer-
ence, while using an e x t e r n a l antenna e x c e p t for the switch-board it is necessary to fit a
lightening conductor,
•before mounting a router on sheet-steel w e re com me n d using an e x t e r n a l antenna,

–With data cables they mustn’t carry cables with retic u la r t e n s i o n ∼230 V/50 Hz.
–All signals to sensors must be twisted pairs.

P o w e r supply for router is re qui red between +10 V to +30 V DC supply. Protection against
reve rs e d polarity without signaling is built into the router.
The power consumption during rec e iv i ng is 2,3 W . The peak power consumption during
data sending is 5,5 W . However, v a l u e s of consumption can be increased, if some e x p a n s i o n
port is eqquipped. F o r 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).
