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 interference 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 emission from digital apparatus set out in the Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.

8.Servicio—El usuario no debe intentar dar servicio al equipo eléctrico más allá a lo descrito en las instrucciones de operación.
Todo otro servicio deberá ser referido a personal de servicio calificado.
9.El aparato eléctrico debe ser situado de tal manera que su posición no interfiera su uso. La colocación del aparato eléctrico sobre una cama, sofá, alfombra o superficie similar puede bloquea la ventilación, no se debe colocar en libreros o gabinetes que impidan el flujo de aire por los orificios de ventilación.
10.El equipo eléctrico deber ser situado fuera del alcance de fuentes de calor como radiadores, registros de calor, estufas u otros aparatos (incluyendo amplificadores) que producen calor.
11.El aparato eléctrico deberá ser connectado a una fuente de poder sólo del tipo descrito en el instructivo de operación, o como se indique en el aparato.
12.Precaución debe ser tomada de tal manera que la tierra fisica y la polarización del equipo no sea eliminada.
13.Los cables de la fuente de poder deben ser guiados de tal manera que no sean pisados ni pellizcados por objetos colocados sobre o contra ellos, poniendo particular atención a los contactos y receptáculos donde salen del aparato.
14.El equipo eléctrico debe ser limpiado únicamente de acuerdo a las recomendaciones del fabricante.
15.En caso de existir, una antena externa deberá ser localizada lejos de las lineas de energia.
16.El cable de corriente deberá ser desconectado del cuando el equipo no sea usado por un largo periodo de tiempo.
17.Cuidado debe ser tomado de tal manera que objectos liquidos no sean derramados sobre la cubierta u orificios de ventilación.
18.Servicio por personal calificado deberá ser provisto cuando:
A:El cable de poder o el contacto ha sido dañado; u
B:Objectos han caído o líquido ha sido derramado dentro del aparato; o
C:El aparato ha sido expuesto a la lluvia; o
D:El aparato parece no operar normalmente o muestra un cambio en su desempeño; o

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 Configuration by SerialManager
4.1.1 Static IP
Use SerialManager that’s included on the product CD to configure the LES301A’s network parameters. Click on the “Configuration” button (see Figure 4-1) then give it static IP information (see Figure 4-2.)
Figure 4-1. Configure using SerialManager.

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 automatically by following these steps:
1.Execute SerialManager (Figure 4-1).
2.Click on the IP address of the LES301A in SerialManager.
3.Click on the “Config” button, and the dialog window will pop up (Figure 4-2).
4.Check ”DHCP (Obtain an IP automatically)” (Figure 4-3).
5.Click on the “Config Now” button (The LES301A will restart and get its IP from the DHCP server automatically.)

4.2 Configuration by Telnet Utility
You can use the Telnet utility to change configuration settings of the LES301A.
4.2.1 Log into the System
Open the MS-DOS® command prompt window.
Telnet to the LES301A using the command “Telnet IP_address.” (For example: Input Telnet 10.0.50.100 in the MS-DOS command prompt window). After you Telnet to LES301A, the system prompts for a password; the default password is blank. (Figure 4-4).
Figure 4-4. Log into the system.
NOTE: Press the LES301A default button to reset the password to the default value.
After verifying the password, the following terminal screen appears (see Figure 4-5).
Figure 4-5. Main menu.
NOTES: If the LES301A does not receive any command within one minute, Telnet will be terminated automatically.
The networking parameter changes will take effect only when you exit and restart the LES301A.
Select “1” from “Input choice and enter (0–4):” to enter the overview page as shown in Figure 4-6.
