FCC WARNING
Class A for Serial Device Server (Model SE5001A)
This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15
of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment uses, generates and radiates radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expenses.
A shielded-type power cord is required in order to meet FCC emission limits and also to prevent interference to the
nearby radio and television reception. It is essential that only the supplied power cord be used.
Use only shielded cables to connect other devices to this equipment by RS-232 or RS-485 ports.
Be cautioned that changes or modifications not expressly approved by the party responsible for compliance could
void ones’ authority to operate the equipment.

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.

1.3 Application Connectivity
TCP Server Mode：SE5001A can be configured as a TCP server in a TCP/IP Network to listen for an incoming
TCP client connection to a serial device. After the connection is established between the serial device server and
the host computer, data can be transmitted in both directions. This also applies to Virtual COM running in the server
mode.
Figure 1.1 TCP Server Mode
User Manual Version 1.0
SE5001A Serial Device Server
7
TCP Client Mode
SE5001A can be configured as a TCP client in TCP/IP Network to establish a connection with a TCP server in the
host computer. After the connection is established, data can be transmitted between a serial device and a host
computer in both directions. This also applies to Virtual COM running in the client mode.
Figure 1.2 TCP Client Mode
User Manual Version 1.0
SE5001A Serial Device Server
8
UDP Mode
UDP is a faster but connectionless network protocol. It does not guarantee the delivery of network datagrams.
SE5001A can be configured to transfer data using unicast or multicast UDP from the serial device to one or multiple
host computers. Data can be transmitted between serial device and host computer in both directions.

User Manual Version 1.0
SE5001A Serial Device Server

Tunneling Mode
In the case that the serial device needs to communicate with each other without a host computer, two SE5001As
can be paired together (pair connection) to communicate over TCP or UDP transparently. The serial device would
be unaware of the change in the communication medium.
