FCC and IC RFI Statements
Federal Communications Commission and Industry Canada Radio Frequency Interference
Statements
This equipment generates, uses, and can radiate radio-frequency energy, and if not installed and used properly, that is, in strict
accordance with the manufacturer’s instructions, may cause inter ference to radio communication. It has been tested and found to
comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emis sion from digital apparatus set out in the Radio
Interference Regulation of Industry Canada.

LES301A user manual
Chapter 2: Overview
2. Overview
2.1 Introduction
The LES301A Ethernet Serial Server is a gateway between Ethernet (TCP/IP) and RS-232 or RS-485/RS-422 communications. The
information transmitted by the LES301A is transparent to both host computers (Ethernet) and devices (RS-232 or RS-485/RS-422).
Data coming from the Ethernet (TCP/IP) is sent to the designated RS-232 or RS-485/RS-422 port and data being received from
the RS-232 or RS-485/RS-422 port is sent to the Ethernet (TCP/IP) transparently.
In the computer integration manufacturing or industrial automation area, the Ethernet Serial Server is used to directly connect
field devices to an Ethernet network. Terminal Server (the main control program that runs in LES301A) transforms whatever data is
received from RS-232 or RS-485/RS-422 to a TCP/UDP port, then connects the devices to the Ethernet network via a single
application program or multiple application programs.
Many control devices provide the ability to communicate with hosts through RS-232 or RS-485/RS-422; however, RS-232 or
RS-485/RS-422 serial communication has its limitations. For example, it is hard to transfer data through a long distance. The
LES301A can communicate with a remote device in the Intranet environment or even in the Internet, which increases the
communication distance dramatically.
The LES301A has (1) RS-232/RS-485/RS-422 port (software selectable), (1) RJ-45 Ethernet and Watch-Dog Timer etc.

2.4 Application Connectivity
TCP Server Mode: LES301A can be configured as a TCP server on a TCP/IP Network to wait for other applications (clients) in the
host computer to establish a connection with the serial device. After the connection is established between the serial device and
the host computer, data can be transmitted in both directions.

Chapter 2: Overview
TCP Client Mode: LES301A can be configured as a TCP client on TCP/IP network to establish a connection with other
applications (server) in the host computer actively. After the connection is established, data can be transmitted between the serial
device and the host computer in both directions.

UDP Mode: UDP is a faster but non-guaranteed datagram delivery protocol. LES301A can be configured as a UDP mode on TCP/
IP Network to establish a connection using unicast or multicast data from the serial device to one or multiple host computers. The
opposite is also true.

3.2 Installation Procedures (LES301A-KIT or LES301AE-KIT)
Step 1: Connect an LES301A to the included power supply (PS012 or PS012E) or to a 9–30 VDC source.
Step 2: Connect the LES301A to an Ethernet network. Use a standard straight-through Ethernet cable to connect to a hub/
switch, or connect it to a PC’s Ethernet port via a cross-over Ethernet cable.
NOTE: The PC must be in the same subnetwork as the LES301A.
Step 3: Connect the LES301A’s serial port to a serial device.
NOTE: You may need an adapter (LES30X-TB5) for RS-485 or RS-422 applications.
Step 4: Mount the LES301A to a wall or panel using the included mounting screws. Or, mount the unit to a DIN rail rack using
the DIN Rail Kit (LES30X-DR).
NOTES: Disconnect the device from power source completely before installing and wiring the server.
Do not exceed the maximum allowable current of the power cord and common wire. If you don’t, the wire might overheat
and cause serious damage to the connected and neighboring equipment.
The casing will be too hot to touch when operating in harsh environments. Please handle with care.
NOTE: Ground the LES301A properly through frame ground.

4.1.2 Auto IP (Dynamic IP)
A DHCP server can automatically assign the IP address and network settings. The LES301A supports the DHCP function. By
default, the DHCP function on the LES301A is disabled; you can use SerialManager software to search network information auto-
matically by following these steps:
1. Execute SerialManager (Figure 4-1).
2. Click on the IP address of the LES301A in SerialManager.
