The Moxa NPort 6450-2TX-G2 is a secure 4 port RS-232/422/485 terminal server designed for industrial networks that need extra Ethernet connectivity at the edge. Unlike basic single port device servers, this model provides three 10/100M RJ45 Ethernet ports, which can be useful for wiring flexibility, panel layouts, and scenarios where you want to simplify the number of upstream switch ports used in a cabinet or junction box.
At its core, the NPort 6400-G2 platform is built around secure connectivity for legacy serial equipment. The NPort 6450-2TX-G2 supports encrypted serial data transmission using TLS and SSH, helping protect device communications when serial traffic is encapsulated over TCP/IP. Secure Boot helps ensure only authorised firmware can run on the unit, supporting lifecycle security and reducing risk in unattended environments. The series is IEC 62443-4-2 Security Level 2 certified, which is a key requirement for many modern industrial and infrastructure projects.
On the serial side, the unit provides four DB9 ports supporting RS-232, RS-422, and RS-485. It supports baud rates from 50 bps up to 921.6 kbps, including non-standard rates, making it suitable for a broad range of PLCs, RTUs, meters, sensors, and specialist serial devices. RS-485 configuration is streamlined with software configurable termination and selectable pull high/low resistors, helping installers stabilise the bus quickly without hardware changes.
For commissioning and support, one click log collection and application analysis helps engineers diagnose connectivity issues faster and reduce downtime. The unit accepts 12 to 48 VDC input and is rated for -10 to 60 degrees C operation. This standard temperature model is supplied with a power adapter in the box, making it easy to deploy in new panels or retrofit projects. If you need secure serial integration plus more Ethernet ports for practical cabinet design, the NPort 6450-2TX-G2 is the most versatile copper Ethernet option in the range.
