Description

The NE-4120S-T is an NE-4100 series serial device server module that connects an RS-232 serial device to a 10/100 Mbps Ethernet network through a 5-pin Ethernet pin header. Built as a ready-to-go embedded module, it is suited to OEMs and integrators adding network connectivity to serial equipment, and the -T variant is rated for -40 to 75°C operation in demanding environments.

The module supports Real COM, TCP Client, TCP Server and UDP operation modes, with configuration through a web console, Windows utility, Telnet or serial console. Real COM and TTY drivers cover Windows, Linux and a range of other operating systems, and built-in 1.5 kV magnetic isolation protects the Ethernet port. Four software-configurable digital I/O channels and a TTL console port add flexibility for integration.

FAQs

Q: What serial interface does the NE-4120S-T provide?
A: It provides one RS-232 serial port with TxD, RxD, RTS, CTS, DTR, DSR, DCD and GND signals, plus a TTL console port for configuration.

Q: How does the module connect to the Ethernet network?
A: It uses a 5-pin Ethernet pin header supporting 10/100BaseT(X) with auto MDI/MDI-X, so a magnetics-equipped connector or carrier board is wired to the header.

Q: What operating temperature range is supported?
A: The -T variant is rated for -40 to 75°C operation.

Q: Which operation modes and drivers are available?
A: Real COM, TCP Client, TCP Server and UDP modes are supported. Real COM drivers are available for Windows and Linux Real TTY drivers for kernel 2.4.x through 5.x, with fixed TTY drivers for several other operating systems.

Q: What power supply does it require?
A: The module runs from 5 VDC and draws 290 mA.

Q: How is the module configured?
A: Configuration is available through the web console (HTTP), a Windows utility, a Telnet console or the serial console.
