Introduction

The NPort 6000-G2 device servers use the TLS v1.2/v1.3 and SSHv2 protocols to transmit encrypted serial data over the Ethernet. The NPort 6000-G2's 3-in-1 serial port supports RS-232, RS-422, and RS-485 with the interface selected via an easy-to-use configuration menu. Furthermore, the pull high/low resistors and terminators are software configurable, eliminating the need to open the product case to adjust them.

IEC 62443-4-2 Security Level 2 Certified

The NPort 6100-G2/6200-G2 Series is IEC 62443-4-2 Security Level 2 certified, making it easier for asset owners and system integrators to integrate IIoT applications by providing a secure platform that has already been tested and validated to protect IIoT data and infrastructure against cyberthreats.

IEC 62443-4-2 Security Level 2 certificate: https://certificates.iecee.org/#/deliverables/CERT/2018356/view

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® 6100-G2/6200-G2 secure terminal servers support the TLS and SSH protocols, which work by encrypting data before sending it over the network. With the NPort® 6100-G2/6200-G2, you can be rest assured that serial data is transmitted securely over both private and public networks.

Easy Provisioning With Side-mount and Software-configurable Pull High/low Resistors and Terminator

In line with the trend for smaller systems and easier setup, the NPort® 6100-G2/6200-G2 secure terminal servers support side-mount installation and two-sided LEDs to fit in a variety of installation scenarios with the added benefit of reduction in the system size. The software-configurable pull high/low resistors and terminator function eliminate the requirement to open the chassis to adjust the pull high/low resistors or terminators, making it convenient for operators to install the devices at field sites.

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 hold discussions with the technical support team. The NPort 6100-G2/6200-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.
