Industrial 4G/3G GTR Routers
Compact industrial routers designed to provide robust and high-speed wireless Internet connectivity over 3G or LTE cellular network for industrial, M2M/IoT and commercial applications.
Devices can be efficiently employed at remote automation facilities. It is recommended to use the GTR routers in M2M solutions area, where quick and secure data transmission over the protected channel is required.
Linux-based OpenWrt operating system capabilities (Firewall, NAT, VPN, etc.) allow creating secure VPN networks and ensure reliable communication system functioning between various nodes.
— AMR/AMI systems, smart grids
— Small business, SOHO network
— Power and energy industry
— POS terminals, ATM, vending
— Security systems (alarm, warning, IP video surveillance etc.)
GTR routers are manufactured in robust aluminum enclosure and can be mounted on a wall or DIN rail.
Series includes the following model lines:
2 x Ethernet 10/100Base-TX (LAN/WAN)
Cellular 3G or 4G modem providing secure Internet connection in any place, where the mobile operator’s network coverage is available
2 x SIM card slots providing communication channel redundancy
Hardware Watchdog timer for router reboot in case of software failures
4 x I/O lines supporting three operation modes: voltage measurement, resistive sensors connection, load control
Linux-based OpenWrt® operating system allows to create secure VPN networks and install user software packages to customize router configuration
1 x RS-232, 1 x RS-485 serial ports. Modbus-TCP – Modbus RTU/ASCII conversion
Temperature compensated real-time clock (RTC) providing high timekeeping accuracy
Additional options can be selected depending on user requests:
GPS module for precise location determination and high accuracy time synchronization (up to 1 msec)
Supercapacitor that provides router back-up power supply for two minutes in case external power supply is disabled
GTR ROUTER CONNECTION SCHEME
The main function of industrial 4G/3G GTR router series is to ensure reliable connectivity solution for AMR/SCADA systems to easily monitor and control remote equipment.
Router provides secure remote access for IoT devices over the 4G network. To create an IoT network, connect meters, sensors, PLCs, to GTR IO lines. IO lines can be configured to operate in 3 modes: voltage measurement, connection of resistive sensors, and load management.
In addition, GTR routers have RS-232 and RS-485 serial ports and support Modbus RTU/ASCII to Modbus TCP conversion, that is, act as a gateway, providing a transparent data transfer channel between devices.
Router is managed using Linux-based OpenWrt operating system. All parameters can be easily configured via the convenient Web Interface.
