Description

NCOM-21X-M is a network-based serial device server. It is designed to control your serial devices located virtually anywhere through a TCP/IP or UDP/IP network connection. The serial device server can map TCP/IP connections and UDP broadcasts to a virtual serial port. Applications include accessing a faraway device for functions such as remote control and data transmission. NCOM-21X-M serves as a transparent virtual serial port without limitations on operating systems and distances. The virtual serial port redirection uses the protocol known as RFC2217.

NCOM-21X-M supports several operation modes, including Driver mode, RFC2217 Server/Client mode, Pair Connection mode, TCP Server/Client mode and UDP mode. It also supports Windows virtual serial port driver, allowing you to add two virtual serial ports in your Windows system to work over a TCP/IP network. The virtual serial port functions as a native Windows COM port and is compatible with Windows serial communication applications. It is installed in the Device Manager of the operating system. This in turn will allow communications with the connected serial device in the same manner as a device physically connected to the COM port on a PC. The serial port supports high serial speeds up to 921.6Kbps in RS-232 for NCOM-211-M, RS-422/485 for NCOM-212-M and RS-232/RS-422/485 for NCOM-213-M.
