Introduction

Introduction

ESP904 can be attached to a network or to the Ethernet port of a
computer (using a crossover cable). Non-Windows users can configure it

CChhaapptteerr 11:: IINNTTRROODDUUCCTTIIOONN

in the Console Mode using an RS-232 port, VT100 Terminal Emulation
program and an RS-232 crossover cable. Telnet also can be used to
access the setup configuration menu.

The VLINX Model ESP904 Quad-Port Ethernet Serial Server provides
Ethernet to Serial connections for RS-232, RS-422 or RS-485 devices. The
serial ports can be accessed over a LAN/WAN using

COM Port

, or Paired Mode connections. The 10/100 Mbps Ethernet

Direct IP Mode, Virtual

connection auto-selects 10BaseT or 100BaseTX and indicates the type of
connection with a bi-color link light.

• Virtual COM Driver Software for Windows - installs a virtual COM

port, viewable in the Windows Device Manager under

. Virtual COM port provides access to any of the ports on the

LPT)

ESP904, like any other serial port (legacy, PCI, USB or PCMCIA) on
the computer. Any program running on the computer and using
Windows-based COM ports can access the serial devices attached to the
ESP904. The LAN becomes transparent to the serial device and the
software running on the PC.

• Heart Beat Connection - selectable protocol ensures reliable

communications in Virtual COM Port or Paired Connection modes. This
feature restores the connections if communications are temporarily lost
at either end due to loss of power or the Ethernet connection.

Communication Modes

The ESP904 enables communication with 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 connections allow applications using TCP/IP or UDP/IP socket

programs to communicate with the asynchronous serial ports on the ESP904.
In this type of application the ESP904 is configured as a TCP or UDP server.
The socket program running on the PC establishes a communication
connection with the ESP904. The data is sent directly to and from the serial
port on the server.

Use Install Virtual COM to add a driver, to provide a virtual COM port on
the computer. The new COM port shows up in the Device Manager.
Windows programs using standard Windows API calls are able to interface
to virtual COM ports. When a program on the PC opens the new COM port,
it communicates with the remote serial device connected to one of the ports
on the ESP904.

Introduction

After connection, the LAN is transparent to the program and serial device.
Applications are able to work just as if the serial device is connected directly
to a physical COM port on the computer. The virtual COM port software
converts the application’s data into IP packets, sends it across the network to
the ESP904, which converts the IP packet back to serial data and sends the
data out a serial port located on the ESP904.

Introduction

ESP904 Quick Start Guide

Hardware Setup

Required hardware:
To use this mode, the ESP904 must be set to either TCP/server or
UDP/server with a designated communication port number. The virtual COM
driver is the TCP or UDP client.

Paired Mode

Paired Mode is also called serial tunneling. In this mode any two serial

devices that can communicate with a serial link will be able to communicate
using two ESP904s and the LAN.

• A PC operating on an Ethernet LAN.

• A serial device with a RS-232 interface.

• Network and serial cables, as required.

Step 1: Connect the ESP904 to the network using a standard network cable

Step 2: Connect the ESP904 to the RS-232 serial device.

Two ESP904s are connected to a network, one configured as a TCP or UDP
client and the other as a TCP/UDP server. When setting up the server the
remote IP address section must contain the address of the client. This will
allow the client’s IP address to pass the IP address-filtering feature of the
server. Conversely, the Remote IP address of the client must contain the
server’s IP address. Both communication port numbers must be the same.

Heart Beat

The Heart Beat protocol connection provides a reliable communications
connection in
This feature restores the connection if communications are temporarily lost at
either end due to loss of power or Ethernet connection.

Without this feature a device that loses a connection and stops
communicating would not be able to reconnect without human intervention.
A TCP data connection can be lost when there is a power failure or
temporary loss of an Ethernet connection on either the client or server. If a
loss occurs the Heart Beat feature will try to reconnect the TCP data
connection every five seconds until communications is established again. The
Heart Beat feature is available for use in

Connection

Virtual COM Port Mode or with Paired Connection Mode.

Virtual COM Port Mode and Paired

mode. This is not available when using a UDP application.

NNoottee::

If the serial device is configured as a DCE use a straight-through serial cable. If
the serial device is configured as a DTE use a crossover (null modem) cable.

Ethernet Connector

The ESP904 has a standard RJ-45 receptacle mounted in the top edge of the

chassis. The ESP904 can be connected to an Ethernet hub, switch, or wall

plate using a standard straight-through RJ-45 (male) Ethernet cable. To

connect directly to an RJ45 Ethernet port on a PC or laptop a crossover

Ethernet cable must be used.

Serial Port Operational Modes

Power Connector

Plug the ultra-miniature phone plug from the included power supply into the
power jack and then plug the supply in. When power is applied the Red
power light will illuminate. The tip of the power plug is positive; the sleeve
is negative.

Reset Button

This switch resets the unit, similar to the effect of removing/applying power.
The Reset switch is recessed to avoid accidental operation. To reset the unit,
insert a small plastic tool, press lightly and hold for 3 seconds. The Link and
Ready lights will go out and then come back on.

Serial Ports

The ESP904 has four serial ports, each configurable through software as RS­232, RS-422 or RS-485 interfaces. The connectors are DTE DB-9M.

Using the ESP Manager or the Console Mode Configuration Menu each

serial port can independently be configured as

or

RS-485 Mode. Port 1 of the ESP904 also can be placed in Console Mode,

Upgrade Mode or Default Mode. Port 1 default setting is Console Mode.

RS-232 Mode, RS422 Mode

Default Mode

When Default Mode is selected and the Server Properties are Updated

(

Saved) all the configuration settings return to their default values. The

default settings for the ESP904 serial ports are:

Console Mode for Port 1;

RS-232 mode for Ports 2, 3 and 4.

Refer to Chapter 5 for details on Server Configuration settings

Console Mode

In Console Mode the ESP904 Configuration Menu can be accessed from a

computer by connecting its RS-232 serial port to the ESP904’s Port 1. Since

the computer is a DTE device, and the ESP904 serial ports are configured as

DTEs (with DB-9M connectors), a null modem crossover cable must be

used.

Console Mode the default serial port settings are: 9600 baud, 8 data bits,

In

No parity, and 1 stop bit. From Windows, HyperTerminal with VT100

terminal emulation can be used for

Console Mode configuration.

Upgrade Mode

Using a similar connection setup to that used in Console Mode, firmware for

the ESP904 can be updated by connecting the ESP904 to a computer via Port

1, using RS-232. (Upgrading also can be done by communicating with the

ESP904 over the network connection, using the ESP Manager software and a

virtual COM port mapped to the ESP904 Port 1.)
