ATOP ER, or Ethernet Router, is an advanced device that allows a very tangible scale-up of almost any industrial infrastructure. In addition to high EMC protection, wide-temperature operation, superb hardware and advanced features, ER will provide high-speed internet access with load balancing and high degrees of security, high speeds and advanced configuration options.

Quad-ARM Cortex A7 CPU
ER integrates an industrial-grade Quad-core A7 ARM CPU, enabling the processing power you need to filter heavy traffic over firewalls, routing, forwarding and security measures.

Harsh Environments
ATOP ER is proven to run at its maximum loading in the harshest EMC and climate environments.

With its integrated 4 x RJ45 LAN ports and 1 x RJ45 WAN Port with VPN feature, ER provides high-throughput connections.

Integrating firewall, zone forwarding, and VPN features, ATOP ER allows you to connect your industrial network to the internet without fearing intrusions into your organization data.

Application - As a Ethernet Router
ER5805 allows you to easily set up a VPN Router environment for providing a secured access to all users. Perfect for VPN deployment where high speed is required, ER can bridge to the remote VPN server via various VPN protocols with secured key exchange algorithms. Finally, these features are all enclosed in a rugged fanless design with operation temperatures from -40°C up to +75°C, to suit applications in any environment.
