Next generation secure terminal servers.

Legacy serial devices made network-ready for deployment on Industrial IP-based Ethernet LANs .

The next generation of RS-232/422/485 secure terminal servers, the NPort 6100-G2/6200-G2 Series has been developed by Moxa. The servers are in accordance with the cybersecurity best practices of IEC 62443-4-1. Because of their IEC 62443 certification, the new terminal servers provide reliable defense against cyberthreats when used to connect legacy serial devices to modern Ethernet TCP/IP networks. Deploying these terminal servers not only eliminate the expense of replacing serial field devices, such as sensors, actuators, HMIs, data loggers, and PLCs, but also helps enterprises avoid the time-consuming build-out of complex security solutions.

Legacy serial communications present significant security challenges to ICS as the protocols were devised before modern cyber threats existed. To address this issue, Moxa NPort 6100-G2/6200-G2 terminal servers support the TLS and SSH protocols that securely encrypt data before sending it over private or public networks. Support of SSL certificate signing by RSA-4096 / ECC-521 also heightens security against modern decryption attempts, while Secure Boot permits only firmware authorized by Moxa to run on the servers.

Consistent with the trend for smaller systems and easier setup, Moxa NPort 6100-G2/6200-G2 secure terminal servers support side-mount installation as an option, alongside desktop, DIN-rail or wall mounting choices. Two-sided LEDs are visually accessible in a variety of installation scenarios. In addition, software-configurable pull high/low resistors and a terminator function eliminate the need to open the chassis to adjust the pull high/low resistors or terminators, making it convenient to install serial devices at field sites. The NPort 6100-G2/6200-G2 Series also comes with a one-click log collection function to enable logging of data, which can provide the information that a technical support team needs to quickly troubleshoot system issues.

Moxa is offering NPort 6100-G2/6200-G2 secure terminal servers in four models with a choice of one or two serial ports, up to 2TB SD card support, and operating temperatures of either -10 to 60°C or -40 to 75° C.
