Wireless Computer As an Edge Gateway

Optimize OT Infrastructure With Reliable and Secure Wireless Computers

Wireless Technologies Bring Efficiency to Data Transmission in Harsh Environments

The UC-3400A and UC-4400A Series computers feature dual wireless capabilities for 4G/5G and Wi-Fi 6/6E, ensuring reliable operations in harsh environments. Leveraging Qualcomm's QXDM, Moxa offers advanced log analysis and troubleshooting support for enhancing wireless connection quality through log analysis, troubleshooting, and protocol decoding.

Moxa Connection Manager Automatic Network Failover Ensures Continuous Connectivity

Moxa Connection Manager (MCM) allows for the creation of multiple profiles for network interfaces. When a connection fails, MCM can automatically failover to a connection with the highest priority based on your profile settings and switch back when the connection is restored. The user-friendly GUI helps set up device connections in just a few clicks.

Streamline Large-scale Deployment With Effortless Provisioning

Moxa Swift offers an intuitive web GUI for configuring and provision supported devices in batches. Use the tool to create a golden sample of the configuration on one computer and used this backed-up configuration settings to batch provision multiple industrial computers.
