MOXA NPort 6600-G2 Series
2nd Gen 8/16/32-port RS-232/422/485 secure terminal servers








- Data encryption with secure operation modes for Real COM, TCP Server, TCP Client, Pair Connection, Terminal, and Reverse Terminal
- Secure Boot only allows Moxa-authorized firmware to run on devices
- One-click log collection and application analysis for easy troubleshooting
- Easy RS-485 configuration of serial interfaces with software-adjustable pull high/low resistor and terminator
- Supports SSL certificate signing by RSA-4096 / ECC-521
- IEC 62443-4-2 Security Level 2 certified
Moxa has leveraged the IEC 62443-4-1 secure development life-cycle process to develop a new generation of NPort G2 secure terminal servers. In addition, the NPort 6600-G2 Series secure terminal servers are also IEC 62443-4-2 Security Level 2 certified, enabling secure connections for your legacy serial devices to industrial networks. User experience is enhanced based on Moxa?s 35 years of experience in the serial-connectivity field by providing versatile installation means for different space requirements and an easy-to-use troubleshooting tool for maintenance.
Secure Data Transmission
For many applications, guaranteeing secure data transmission is an important concern when connecting serial devices to a network. To answer this concern, the NPort® 6600-G2 secure terminal servers support the TLS and SSH protocols, which work by encrypting data before sending it over the network. With the NPort® 6600-G2, you can be rest assured that serial data is transmitted securely over both private and public networks.
One-click Logs and Application Analysis for Easy Troubleshooting
During the deployment stage, system integrators must connect devices and ensure the communication is smooth. They may encounter issues and
will require tools to troubleshoot issues. Moxa provides a application analyzer that generates a report at the click of a button to help the system
integrator easily identify potential issues and understand how to resolve them.
At the maintenance stage, system errors may require you to call for help. Device vendors might take a long time to troubleshoot issues because
they need to collect information and then hold discussions with the technical support team. The NPort 6600-G2 comes with a one-click log
collection function, which can provide all the data that a technical support team needs to quickly troubleshoot system issues.
