Moxa NPort 6610-16 (UK),16 p RS232 Secure Device Server

The Moxa NPort 6400/6600 Series are high-performance, secure terminal servers that connect 4, 8, 16, or 32 serial RS-232/422/485 devices to an Ethernet network. Built with advanced security and redundancy features, these servers are ideal for critical infrastructure sectors including utilities, transportation, and manufacturing.

With support for TLS and SSH encryption, the devices provide secure serial-to-Ethernet transmission. Each serial port can be individually configured, and the 6600 models support adjustable termination and pull resistors for RS-485. If the Ethernet connection fails, a 64 KB port buffer ensures no data is lost—data is forwarded when connectivity is restored. Storage can be expanded via an SD card (up to 32 GB).

The NPort 6600 models come with an intuitive LCD panel for on-device configuration (standard temperature models only). Installation options include rack, DIN-rail, and wall mounting.
