Overview

The STE400A-232 / STE800A-232 are 4 or 8-port IP Device Servers that provide communication with asynchronous RS-232 (3 or 5 wire) devices located virtually anywhere over a TCP/IP connection.
The STE400A-232 / STE800A-232 have 4 or 8 DB9 serial ports and a 10/100 Mbps Ethernet connection. They connect serial devices such as PLC, alarm sensors and PTZ camera control to IP networks.

Applications include industrial/factory automation,public safety and surveillance systems.The supplied STE400A-232 / STE800A-232 Windows® driver is designed to control the IP Serial Server. The driver installs a virtual COM on Windows® which maps a COM port to the IP address of the IP Serial Server across the network, enabling Windows® applications to access remote serial devices over Ethernet. IP Device Server can function as a server or client for TCP connection that provides a Serial over Ethernet solution.

Application scenarios for the STE400A-232 / STE800A-232 include direct IP mode, virtual COM mode, or paired mode.  When in the paired mode one IP Serial Server will be set as a client while the other will act as a server for TCP connection.

Use with Windows®

The VCOM serial port redirector for Windows® is configured using a control-panel style graphical user interface for creating virtual COM ports, configuring settings for individual COM ports, and configuring global settings affecting all COM ports. The VCOM GUI also includes displays of virtual COM port activity and various diagnostic aids. VCOM allows legacy serial programs that access the PC communications ports (COM1, COM2, etc.) to access the device server by IP address, just as if it were an actual communications port.

An intuitive web based graphical user interface may be used to configure the STE400/800.  Alternatively, a console interface is accessable using the port redirection driver and any terminal emulation software.
