Moxa

The MOXA NPort 6610-32-G2 is the highest-density RS-232-only model in the NPort 6610 branch, making it a strong choice for large-scale serial-to-Ethernet deployments where many legacy devices need to be consolidated into a single rackmount terminal server. With 32 RS-232 ports, this model is ideal for central control rooms, large equipment racks, traffic management systems, building automation hubs, and industrial sites where a high concentration of serial endpoints must be managed from one secure platform. Its high port count helps reduce cabinet clutter and lowers the need for multiple smaller serial servers, which can simplify maintenance and network design. Like the wider NPort 6600-G2 family, it is built with secure networking in mind, including TLS and SSH encryption, Secure Boot, SNMPv3, RADIUS, TACACS+, and IEC 62443-4-2 Security Level 2 certification. That security focus makes it especially relevant for infrastructure operators modernising older serial estates but still needing compliance-minded network integration. 

In terms of positioning, the NPort 6610-32-G2 is best described as a high-port-count RS-232 terminal server for industrial serial aggregation and secure remote access. The clear difference from the NPort 6610-8-G2 and 6610-16-G2 is simply scale: it is built for users handling dozens of RS-232 devices in one location. The key difference from the NPort 6650 family is flexibility: the 6610-32-G2 is limited to RS-232, so it is the right model where all connected devices use classic RS-232 signalling and there is no need for RS-422 or RS-485 multidrop support. The unit includes 2 x 10/100/1000M Ethernet ports, support for Real COM and multiple secure operating modes, plus Moxa’s one-click log collection and application analysis to make troubleshooting faster for integrators and maintenance teams. Rated for -10 to 60°C and supplied with 1 power cable, it is a practical fit for standard industrial environments, equipment rooms, and secure network cabinets where high serial density is the main requirement. It also benefits from the same rackmount-friendly mechanical design and broad industrial certification set as the rest of the family.
