The MOXA NPort 6650-8-G2 is an 8-port secure terminal server designed for users who need more serial flexibility than the 6610 models can provide. Unlike the 6610 branch, which is limited to RS-232, the NPort 6650 family supports RS-232, RS-422, and RS-485, making the 6650-8-G2 a strong fit for industrial control, utilities, process automation, traffic systems, and building infrastructure where different serial standards may be encountered in the same project. This flexibility is particularly valuable in brownfield environments, where newer and older serial devices often coexist and integrators need a single platform that can bridge them into Ethernet networks securely. The model supports Moxa’s secure operation modes, encrypted communications, and hardened authentication framework, allowing legacy serial devices to be integrated into industrial networks without leaving data exposed in transit. That makes the NPort 6650-8-G2 suitable for modern cyber-aware projects where simple serial-to-Ethernet conversion alone is no longer enough.
From a product-page perspective, the NPort 6650-8-G2 should be positioned as a secure 8-port RS-232/422/485 terminal server for industrial serial networking and remote device access. Its main difference from the NPort 6610-8-G2 is the addition of RS-422 and RS-485 support, including automatic data direction control and software-configurable terminator and pull high/low resistor settings for RS-485, which makes it more suitable for field buses, multidrop devices, and longer serial runs. Compared with the 16-port and 32-port 6650 variants, this SKU is better for compact deployments with fewer serial endpoints. It includes 1 power cable, operates from -10 to 60°C, and supports 2 x Gigabit Ethernet, Real COM, TCP/UDP-based modes, one-click log collection, and application analysis. Security features include Secure Boot, TLS 1.2/1.3, SSHv2, SNMPv3, RADIUS, TACACS+, and IEC 62443-4-2 Security Level 2 certification. It is therefore a strong option for secure machine connectivity, remote I/O integration, power automation, and industrial control applications where mixed serial standards need to be brought safely onto Ethernet.
