SE5001A Serial Device Server
1 Introduction
The SE5001A Ethernet Serial device server acts as a gateway between Ethernet (TCP/UDP) and
RS-232/RS-422/RS-485 communications. The information transmitted by SE5001A
is transparent to both host
computers (Ethernet) and serial devices (RS-232/RS-422/RS-485). Data coming from the Ethernet is sent to the
designated RS-232/RS-422/RS-485 port and data received from RS-232/RS-422/RS-485 port is sent to the
Ethernet transparently allowing bidirectional communication.
In the computer-aided manufacturing or industrial automation areas, SE5001A is used by field devices to directly
connect to an Ethernet network. The user can then use a network application or use Virtual COM software to
simulate a virtual com port in the PC to fetch serial data from SE5001A remotely over Ethernet.
With SE5001A, it is possible to communicate with a remote serial device in the LAN or even in the Internet, which
dramatically increases reach in distance and scalability.
