MOXA Device server - NPort 5430I - 4-port, 10/100M ethernet, RS-422/485 terminal block, w/ 2 kV isolation, 12~48 VDC

Make up to 4 RS-422/485 serial devices Internet-ready
The NPort 5430 Series provides a convenient and transparent way to connect serial devices to an Ethernet, with basic configuration all that's needed to network your existing serial devices. Protect your current hardware investment, but also ensure future network expandability. Moreover, NPort 5430 can transparently transmit data bi-directionally between the serial and Ethernet interfaces.You can simultaneously centralize your serial device management and distribute management hosts over the network.

Easy-to-use Serial Device Server
The built-in LCM human-machine interface displays all configuration parameters,and includes 4 buttons for inputting data, or for selecting the operation mode, making it easy to set up server parameters, including IP address, netmask, and gateway address. Furthermore, you can also monitor server status and data transmission, eliminating the need to prepare additional PCs during installation.

Real COM/TTY Port
NPort 5430 works like an add-on multiport serial board to the Windows host, but with one major advantage—the TCP/IP network. With NPort's Real COM/TTY drivers, the serial ports on NPort 5430 are recognized as Real COM ports by the Windows operating system, or Real TTY ports by Linux environments. The usual transmit/receive data signals are provided for RS-422, and 2-wire and 4-wire RS-485.

4 independent serial ports can be configured for different operation modes
Versatile operation is ensured since different modes can be used for different serial ports. NPort 5430 Series products are suitable for connnecting different devices for remote data polling, event handling, or data multicasting via the TCP/IP network. For example, you can configure NPort 5430's port 1 for driver mode, port 2 for TCP server mode, and ports 3 and 4 for TCP client mode.
