STE-100A-SERIAL RS-232/RS-422/RS-485 to Ethernet IP Terminal Server

The STE-100A-SERIAL IP Device Server provides the serial device server for hosts to control RS-232, 2 or 4 wire asynchronous RS-422/485 serial devices located virtually anywhere through a TCP/IP or UDP/IP connection. The Device Server has the DB9 port connection on one side, and a 10/100 Mbps Ethernet connection on the other side. It connects 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 IP Device Server Windows driver is designed to control the IP Serial Server devices. The driver installs a virtual COM on Windows which maps the virtual COM port to the IP address of the IP Serial Server device across the network, enabling the Windows applications to access remote serial devices over Ethernet. IP Device Server can function as a UDP or a server or client for TCP connection. The application scenarios are direct IP mode, virtual COM mode, and paired mode.

The STE-100A-SERIAL terminal server(access server) allows RS-232/RS-422 or RS-485 enabled devices to connect over Ethernet(10/100Base-TX) using TCP/IP protocol. This small powerful device allows serial only managed devices to be seen and controlled over Internet. STE-100A-SERIAL can be managed either from serial port or RJ-45 Ethernet side. Serial port is DTE, which allows direct connection to a DCE device (like modem). For connection to a DTE also equipment (like PC) a null-modem (cross-over) cable is required.
