Introduction

Communication Modes

ES1A Ethernet to RS-232 converters allow you to connect serial devices

over a LAN or WAN. Serial devices no longer are limited to a physical
connection to the PC COM port. They can be installed anywhere on the LAN
using TCP/IP or UDP/IP communications. This allows traditional Windows
PC software access to serial devices anywhere on the LAN/WAN network.

Direct IP

Direct IP Mode allows applications using TCP/IP or UDP/IP socket
programs to communicate with the asynchronous serial ports on the serial
server. In this mode the ES1A is configured as a TCP or UDP server. The
socket program running on the PC establishes a communication connection.
The data is sent directly to and from the serial port on the server.

TCP Server Mode allows network devices to initiate a TCP connection to
the serial device connected to the serial port on the ES1A. This is also
referred to as reverse telnet.

UDP Server Mode allows network devices to initiate a UDP connection to
the serial device attached to the serial port of the ES1A. When using UDP
protocol the ES1A can be configured to broadcast data to and receive data
from multiple IP addresses.

Virtual COM Port

Virtual COM Port mode (also called RealPort, or com port redirection)
allows you to map a COM port on your PC to the serial port on your ES1 A.
Using the RealPort software (included with the ES1A) you create virtual
COM ports on your PC. When your application sends data to this port,
RealPort redirects the data across the network to serial device connected to
the ES1A serial port. The network is transparent to the user application and
the serial device connected to the ES1A.

Paired Mode

Paired Mode (also called Serial Tunneling or Serial Bridge mode) allows
serial devices connected to two ES1A converters to communicate across a
network. The two ES1A converters automatically connect to each other.

In Paired Mode the heartbeat feature ensures reliable communications by
restoring the connection if communications are temporarily lost at either end
due to loss of power or Ethernet connection.

Introduction

Other Communications Modes

ES1A Converters also feature the following communications profiles:

Modem Emulation Mode allows you to configure the serial port to operate
as if it is a modem. For legacy applications where a serial device is set up to
communicate through a modem, the serial device can now be connected to
the ES1A and communication occurs over the network. The ES1A emulates
modem responses to and from the serial device.

In Console Management Mode the ES1A can be configured for connectio n
to the management port typically found on network devices such as routers,
switches and servers. This allows remote management of the network device.
Communication can be accomplished using telnet to a specific port in the
converter.

Custom Mode allows you to custom configure the ES1A serial port and is
used if your application does not fit into any other predefined modes.

Configuring the ES1A

CChhaapptteerr 44:: CCoonnffiigguurriinngg tthhee IIPP AAddddrreessss

Before you can begin the configuration of your ES1A you must know its IP
address to access it with a web browser. Once you have access to the
Configuration and Management Interface via a web browser you can reset the
IP address using static IP addressing, if necessary.

Your ES1A comes from the factory configured to obtain an IP address
dynamically, or failing that, to generate its own IP address using the APIPA
protocol. You can determine the current IP address using the discovery
software included on the CD with your ES1A

Using the Discovery Software

1. Connect the ES1A to your network (with PoE supply installed and

operating). When it starts it will obtain an IP address.

2. To determine the initial IP address of your ES1A, start the finder.exe

utility included on the included CD.

Figure 5. Discovery Utility Dialog

3. The finder.exe utility scans the network for devices and then lists

each device’s IP Address, MAC Address, Name and Product ID.
Identify your ES1A by its MAC address (printed on a label on the
ES1A).

RealPort

Select RealPort to implement th e use of virtual COM ports. This allows you
to map a COM port on a PC to the serial port on your ES1A. Using RealPort
software (included with the ES1A) you create a virtu al COM port on the PC.
When your application sends data to this port, RealPort redirects the data
across the network to the ES1A. The ES1A passes the data to the serial
device connected to its serial port. The network is transparent to the user
application and the serial device connected to the ES1A.

For information on how to use RealPort to create virtual COM ports on your PC
see Chapter 8

Console Management

In Console Management the ES1A can be configured for connection to the
management port typically found on network devices such as routers,
switches and servers. This allows remote management of the network device.
Communication can be accomplished using telnet to a specific port in the
converter.

Using RealPort

CChhaapptteerr 88:: UUssiinngg RReeaallPPoorrtt

RealPort is a COM port redirector program that allows you to add and
remove virtual COM ports on your PC and update the RealPort software.

Virtual COM ports allow you to set up a connection between your PC and the
device connected to the serial port on your ES1A via an Ethernet network
connection using TCP/IP. If you will be using virtual COM ports
(configuring your serial port with the RealPort profile) you must use RealPort
to configure those ports on your PC. Once you have co nfigured a new v irtual
COM (VCOM) port using RealPort, application software can communicate
through that COM port as if it is located within the PC.

There are three steps to setting up a virtual COM port with RealPort.

1. Configure the ES1A with an IP address

2. Configure the ES1A serial port for RealPort (VCOM) mode

3. Configure the port itself using RealPort
