Moxa NPort 6610-32-48V , 32 Port RS232 Secure Device Server content_copy

The NPort 6610-32-48V from Moxa is a Device-Server of the NPort 6600 series, specifically designed for integrating serial RS-232 devices into TCP/IP networks. It serves as a bridge between legacy serial devices and modern network infrastructures, enabling communication over Ethernet- or IP-based systems. With 32 serial ports, it offers high connection density and is designed for industrial environments where reliability and security are paramount.

Applications
This Device-Server is suitable for use in industrial facilities, such as in manufacturing automation, power supply, or machine building. It enables remote control and monitoring of devices communicating via serial interfaces over existing networks. Support for industrial protocols and high security functions make it particularly suitable for critical applications requiring enhanced protection.

Functions and Features in Detail
Each serial port features an integrated 64 KB port buffer, which prevents data loss during brief network outages or data overloads. The buffer size can optionally be expanded up to 32 GB via an SD card. The serial interfaces are configurable for RS-232, RS-422, or RS-485, with baud rates adjustable from 50 bps to 921.6 kbps, including non-standard baud rates. The serial connectors are implemented as 8-pin RJ45 connectors, ensuring a standardized and robust connection.

Technology Explained Simply
The NPort 6610-32-48V features an Ethernet port with 10/100BaseT(X) and Auto MDI/MDI-X, enabling flexible network connectivity. The 1.5 kV isolation protects against electrical disturbances. Network functions include IPv6 support, as well as redundancy mechanisms such as STP, RSTP, and Turbo Ring (when using a network module). Encryption security is ensured through TLS 1.2, SSHv2, AES-128/256, HMAC, RSA-1024, and SHA-1/256/384. Authentication is performed locally, via RADIUS, or TACACS+.

Compatibility and Accessories
Devices from the NPort 6600 series are designed for mounting in rack systems and can also be mounted on DIN rails or walls. Network functionality can be extended using NM modules for RJ45 or fiber (100BaseFX). The serial ports are manually adjustable, particularly the RS-485 resistors, to optimize signal quality in demanding environments.

Mounting and Installation
Installation is performed using the integrated LCD configuration display and button control (only on standard models of the 6600 series). Alternatively, configuration can be done via a web console (HTTP/HTTPS), Telnet/SSH, DSU, or the MCC tool. The operating temperature is 0 to 55 °C (standard version), with HV models capable of operating up to 85 °C. Relative humidity is 5–95 % (non-condensing). The enclosures are made of metal and meet requirements for industrial robustness.

Operational Advantages
The Device-Server offers high availability thanks to the integrated port buffer and support for redundancy protocols. The flexible configuration of operating modes—including Real COM, TCP Server/Client, UDP, Reverse Telnet, PPP, and RFC2217—allows adaptation to various application scenarios. Security functions such as HTTPS, SNMPv3, and SSHv2 protect data transmission from unauthorized access. Certifications include IEC 61000-4-x, CISPR 32, FCC Part 15B Class A, UL 60950-1, NEMA TS2, RoHS, and WEEE, as well as vibration and drop testing according to IEC 60068, ensuring reliability in demanding environments. The MTBF is up to 850,000 hours (model-dependent).
