The Moxa NE-4120-ST is a starter kit for the development and evaluation of embedded device servers from the NE-4100 series. It serves as a platform for OEM applications and enables rapid integration and prototyping for serial-to-Ethernet capable devices. The kit is specifically designed for developers and device manufacturers who wish to integrate NE-4100 series modules into existing systems. It supports the use of NE-4120S and NE-4120A modules, which are connected via a pin header, and provides a foundation for developing industrial network devices.

Applications

The NE-4120-ST starter kit is suitable for developing devices that connect serial interfaces to Ethernet. It is used in environments where existing serial devices need to be integrated into modern network infrastructures, for example in automation technology, machine control, or industrial communication. The platform enables the creation of prototypes and validation of functionalities before series production.

Features and Equipment in Detail

The kit includes an evaluation board that serves as a base for mounting and testing compatible modules. The board is designed for use with NE-4120S and NE-4120A modules, which are connected via a pin header. The integrated network interface supports 10/100 Mbps Ethernet, enabling stable and fast data transmission in local networks. The serial interface supports baud rates up to 230.4 kbps, which is sufficient for most industrial applications. Power supply is provided by an included power adapter delivering +5 VDC, ensuring a low power consumption of typically 1.5 W.

Technology Explained Simply

The evaluation board acts as a carrier for the embedded modules and provides the necessary connections for network and serial communication. The Ethernet interface enables integration into existing networks, while the serial interface establishes a connection to legacy devices. The low power consumption of 1.5 W at 5 VDC makes the kit energy-efficient and suitable for applications where power consumption is a consideration. Support for baud rates up to 230.4 kbps ensures sufficient data transfer rates for serial communication in industrial environments.

Compatibility and Accessories

The NE-4120-ST kit is specifically designed for use with NE-4120S and NE-4120A modules, which are connected via a pin header. The kit includes all necessary cables and accessories for development and testing: a crossover Ethernet cable, a null modem serial cable, a universal power adapter, and power cords for EU and US sockets. Additionally, a Quick Installation Guide and a warranty card are included in the delivery scope.

Mounting and Installation

Mounting is performed by securing the compatible NE-4120S or NE-4120A module onto the evaluation board via the pin header. Connections for Ethernet and serial interface are directly available on the board. Power supply is provided by the included power adapter, which is connected to a wall socket. Installation is simple and does not require special tools. The included cables and Quick Installation Guide support the user during setup.

Advantages in Operation

The NE-4120-ST kit offers a quick and easy way to test and develop the functionality of embedded device servers. The integrated network interface and serial interface enable direct connection between legacy devices and modern networks. The low power consumption and compact design make the kit suitable for applications in space-limited environments. The 5-year warranty provides additional security for operation.
