Introduction
The Case Communications 6402 Router / Gateway is an Industrial ADSL Router, and Modbus
Cellular Gateway for M2M (Machine-to-Machine) applications,
With a built-in 4G LTE and ADSL2+ module, you just need to insert a SIM card from a local mobile
carrier to get access to the Internet. The redundant SIM and mobile/ADSL combo-WAN design
provides a reliable WAN connection for critical applications. By using VPN tunnelling technology,
remote sites easily become a part of your Intranet, and all data is transmitted over a secure (256-bit
AES encryption) link.
To meet a variety of M2M application requirements the 6402 Industrial Router / Gateway includes
VPN, firewall, NAT, port forwarding, DHCP server and many other powerful features for complex
and demanding business and M2M (Machine-to-Machine) applications.
With its redundant design, dual 9-48 VDC power supplies, dual SIM cards and VRRP function makes
the 6402 suitable for non-stop operation.
Main Features:
•Provide various and configurable WAN connection.
•Support dual SIMs for the redundant wireless WAN connection.
•Support ADSL2+ uplink connection ability.
•Provide Ethernet ports for comprehensive LAN connection and the LAN-1 port can be
configured to be another WAN interface.
•VPN and NAT firewall to have powerful security.
•Supports local or remote management to monitor the network.
•Designed in a solid and easy-to-mount metal body for business and IoT environment to work
with a variety M2M (Machine-to-Machine) applications.
Before you install and use this product, please read this manual in detail to fully understand the
features and functions of the 6402.
