Lantech TMR-5002 series is a next generation EN50155 multi-function VPN router up to 2x LTE modem + 2x Gigabit Ethernet(incl.1 PD)+ 2 serial ports that supports advanced function of VPN, Load-balancing**, EMMC Flash Storage**, Protocol gateway(Modbus), Storage**, and LTE dual SIM fail-over for on-board / onboard-to-ground 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, TMR-5002 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.

Optional EMMC Flash storage**
The optional EMMC flash storage on router can offer 8G/16G/32G capacity.

Load Balancing** with 8 mechanism for multi-WANs (premium license)
TMR-5002 supports Load Balancing** for LTE/WAN connections. There are eight schemes for Load Balancing** function:

Pack Algorithm Description
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, Modbus gateway
It builds in 2 port serial connection for RS232; RS422/ 485 in which RS422/485 has 2.5KV isolation protection. The built-in Modbus gateway can convert Modbus RTU/ASCII to Modbus TCP for device control.

Support various VPN applications and firewall
Besides traditional VPN peer to peer tunneling, TMR-5002 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 TMR-5002 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**.

Wide range dual isolated input voltage from 16.8-137.5V (WV model)
The TMR-5002 is able to work from dual16.8V ~137.5V DC isolated input (WV model) that is particular good for vehicle, rail train, depot etc applications.

Environmental monitoring for inside router info& alerting; 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.

Editable login page of captive portal
The TMR-5002 supports editable captive portal function that allows administrator to force end-users redirect to authentication page.

USB port for back up, restore configuration and upgrade firmware* Dual image firmware*
The built-in USB port can upload/download/upgrade the configurations through USB dongle for router replacement It supports dual-image firmware* to choose which one to start

Ruggedized EN50155 design and FCC/CE & E-marking** certificate
The TMR-5002 series is verified with EN50155, EN61373, EN45545 standard with IP65/54 housing. It passed tests under extensive Industrial EMI and environmental vibration and shocks standards. With CE & FCC radio certification for LTE and E-marking** certificate, the TMR-5002 is best for outdoor community, vehicle, power substation, process control automation etc application. For more usage flexibilities, TMR-5002 supports operating temperature from -20°C to 75°C or -40°C to 75°C(-E)
