The Moxa NPort 6150 is a 1-port serial server that integrates RS-232/422/485 support and enables secure transmission of serial data over Ethernet. The device offers a 3-in-1 serial port selectable via the configuration menu and is designed for industrial environments where remote access, reliable communication, and encrypted data transfer are required.
Advantages
The NPort 6150 provides multiple secure operation modes including Real COM, TCP Server, TCP Client, Pair Connection, Terminal, and Reverse Terminal. It supports nonstandard baud rates with high precision and automatic RS-485 data direction control. Enhanced remote configuration is available via HTTPS and SSH, and the device can buffer serial data when the Ethernet link is offline. IPv6 is supported, and generic serial commands can be used in Command-by-Command mode. Security features follow IEC 62443 guidelines and the device is compatible with Moxa's MXview management software through a plug-in.
Suitable for
- Connecting legacy serial devices (RS-232/422/485) to Ethernet networks
- Industrial automation systems requiring secure remote access
- Applications needing encrypted serial data transfer over public or private networks
- Environments where temporary network outages require serial data buffering

How to use
Install the NPort 6150 in your network and connect the serial device to its 3-in-1 port. Use the device configuration menu or Moxa configuration tools to select the required serial interface (RS-232, RS-422, or RS-485), set the baud rate (including nonstandard values if needed), and choose the appropriate operation mode (Real COM, TCP Server/Client, Pair Connection, Terminal, or Reverse Terminal). Enable HTTPS or SSH for secure remote management and, if required, configure SSL/SSH for encrypted data transmission. Optionally integrate the device with MXview for centralized monitoring.
Usage recommendations
For secure deployments, enable SSL/SSH and configure strong authentication settings; use the port buffer feature if your application must tolerate temporary network interruptions. Verify interface selection and wiring when switching between RS-232, RS-422, and RS-485 modes.
