General
Auto-MDI/MDI-X

The NPort 6610-32 from Moxa is a Device-Server of the NPort 6600 series, specifically designed for integrating up to 32 serial devices (RS-232/422/485) into modern TCP/IP networks. It serves as a bridge between legacy serial devices and modern network infrastructures, enabling data transmission over Ethernet connections. The series is characterised by high security standards, particularly through encryption technologies such as TLS and SSH, as well as features compliant with the standard IEC 62443, making it suitable for security-critical industrial applications.

Applications

The NPort 6610-32 is used in industrial environments where serial devices such as sensors, controls, measuring instruments or machines need to be connected to an IP-based network. It is particularly useful in installations requiring high availability and data integrity, such as in manufacturing, energy supply or transportation. Support for IPv6 and a variety of operating modes extend its application possibilities in modern, networked systems.

Functions and Equipment in Detail

The Device-Server features 32 serial ports connected via 8-pin RJ45 connectors. The baud rate can be set between 50 bps and 921.6 kbps, including non-standard rates. Each port has an integrated buffer memory of 64 KB, which stores serial data in case of Ethernet failure and forwards it without delay once the connection is restored. This ensures uninterrupted data transmission. The buffer size can optionally be extended via an SD card, with capacities up to 32 GB possible.

Technology Explained Simply

The serial interfaces support RS-232, RS-422 and RS-485 standards, with RS-485 resistors manually adjustable via DIP switches on the device. This enables adaptable signal transmission in complex industrial environments with high immunity to interference. The network connection is made via a 10/100BaseT(X) Ethernet port with Auto-MDI/MDI-X and 1.5 kV isolation, ensuring a robust and reliable connection. Support for protocols such as TCP/IP, UDP, HTTP/S, SNMPv3, Telnet and LLDP enables flexible integration into existing networks.

Compatibility and Accessories

The NPort 6610-32 is compatible with a variety of operating modes, including Real COM, TCP Client/Server, UDP, Terminal and Reverse SSH. Full IPv6 support extends network capabilities. Configuration is performed via a web console (HTTP/HTTPS), Telnet/SSH, a Windows utility, DSU or the MCC tool. Standard models of the 6600 series feature an LCD display, enabling direct configuration on the device. Expansion options include NM modules for RJ45 or 100BaseFX fibre optics, allowing flexible adaptation of the network connection.

Mounting and Installation

The device is housed in a metal housing and can be mounted in a rack. Dimensions are 440 x 195 x 44 mm (without mounting brackets). Mounting is done using pre-installed rack mounting brackets included in the delivery. Alternatively, the device can also be mounted on a DIN rail, wall-mounted, or placed on a table, depending on the model. The operating temperature is 0 to 55 °C (standard version), with HV models capable of operation up to 85 °C. Humidity is 5–95 %, non-condensing.

Operational Advantages

The NPort 6610-32 offers high availability through the integrated data buffer, which stores data during network disruptions. Security features, including authentication via RADIUS or TACACS+ and encryption with AES-128/256, HMAC, RSA-1024 and SHA-1/256/384, protect data transmission. Support for HTTPS (TLS 1.2) and SSHv2 ensures secure communication. Certification according to EN 55032/35, CISPR 32, FCC Part 15B Class A, as well as UL 60950-1 and NEMA TS2, confirms EMC and safety compliance. The MTBF is up to 850,000 hours, indicating high reliability.

Scope of Delivery

The scope of delivery includes the device NPort 6610-32, two rack mounting brackets, a DB9-to-RJ45 cable, a power supply or power cable (model-dependent), a quick start guide and a warranty card. The listed components are specific to the 6600 series and support the installation and operation of the device.
