Lantech IMR-3204DF series is a next generation industrial multi-function VPN router w/up to 2x LTE modem + 4x Gigabit Ethernet ports including 2 dual speed SFP+ 2 serial ports that supports advanced function of VPN, Load-balancing**(Basic & Full package), EMMC Flash Storage**, Protocol gateway(Modbus), and LTE quad SIM fail-over for industrial applications. The dual core CPU with 1.6GHz + 256M flash enables the router to multi-task smoothly.
Dual concurrent LTE design 4G/3G for load-balancing
With dual LTE module design (2L model), 4 SIM card slots, IMR-3204DF can allow auto-swap, failover & failback between multiple service providers for real non-stop connection. With concurrent LTE modules, it can also allocate bandwidth by Load Balancing** with 8 schemes between multiple WANs. With one mobile LTE module (1L model), 2 SIM card slots, IMR-3204DF provides redundant link between two service providers. Both GPS and Russian GLONASS systems are supported.
Optional EMMC Flash storage**
The optional EMMC flash storage on router can offer 8G/16G/32G capacity.
Load Balancing** with 8 mechanisms for multi-WANs (premium license)
IMR-3204DF supports Load Balancing** for LTE/WAN connections. There are eight schemes for Load Balancing** function:
|Standard||Fixed||Manually route by traffic type through fixed WAN link.|
|Basic Package||Failover||Routes connections through preferred WAN link while others stand-by. Sequentially activate another link if preferred link fail occurs. Once failover will not failback until link loss.|
|Priority||Routes connections through preferred WAN link as primary while others follow by. Ex. Wi-Fi client>LTE>others|
|Weighted Round-Robin||Evenly distribute the traffic over all working WAN links in circular order according to the specified weights.|
|Custom Route||Routing through the selected WAN for each specific traffic, ex: TCP/UDP port number and IP address.|
|Full Package (incl. basic package)||Sticky Session*||Binding all connections in an application session to particular WAN link to ensure all connections in the session are routed to the same WAN link , that is suitable for security services like online payment etc.|
|Smallest Load*||Routes connections through the WAN link with highest free bandwidth ratio.
The ratio = 1 – (traffic load / the capability of a WAN link).
The traffic load could be defined by downstream, upstream or total traffic
|Fastest*||Routes connections through the WAN link with lowest latency time.|
2 port serial connection
It builds in 2 port serial connection for RS232, RS422, 485 in which RS422/485 has 2.5KV isolation protection.
Managed switch Function
W/ port managed functions, QOS, VLAN, Multicast, Redundant protection, security
VPN and firewall
Besides traditional VPN peer to peer tunneling, IMR-3204DF support latest Multi-Site VPN function that is an efficient way for mesh tunneling. The registration is under cloud service and encrypted by SSH makes the connection easy and safe. It supports Multi-Site VPN, Open VPN, L2TP, IPsec L2 over GRE, NAT, and PPTP** for various VPN applications. The built-in Layer-4 firewall includes DoS**, IP address filter / Mac address filter* / TCP/UDP port number.
DIDO for alarm & email** notice; Event log; Remote Web/SMS** control
2 sets of DIDO function can support additional high/low physical contact for designate applications besides Port / Power events, for example, DIDO function can trigger alarm if the router was moved or stolen. In case of events, the IMR-3204DF will immediately send email** and trap. When the router is at remote area with limited access, Web/SMS** control can help to get router status or remotely reboot by Web/SMS**.
24V/HV isolated input voltage selection: dual 9V-60VDC (24V model) or single 90~305VAC/120~430VDC (HV model)
The IMR-3204DF is able to work from 9VDC to 60VDC (24V model). Or with single high power supply at 90~305VAC / 120~430VDC (HV model).
Environmental monitoring for inside router info& alerting; Graphic LTE signal strength and TX/RX rate display
The built-in environmental monitoring can detect router ambient temperature, voltage, current where can send the syslog, email** and SMS** alert when abnormal.
Ignition sense allows you to delay power off the router with a designated time delay.
Built-in Managed Switch Function
Managed switch function is built-in and provides various L2+ functions for network access deployment. It delivers ports and PoE management, VLAN, QoS, multicast, redundant ring, and security functions.
Dual image firmware
It supports dual-image firmware to choose which one to start.
Ruggedized industrial design and FCC*,CE*& E-marking** certificate
The IMR-3204DF is designed to meet with industrial network environment with IP 30 housing. It passed serious tests under extensive Industrial EMI and environmental vibration and shocks standards. With CE & FCC radio certification for LTE and E-marking certificate, the IMR-3204DF is best for outdoor community, vehicle, process control automation etc application. For more usage flexibilities, IMR-3204DF supports wide operating temperature from -20°C to 75°C & -40°C to 75°C (-E model)
