Introduction

Chapter 1: INTRODUCTION

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 Direct IP Mode, Virtual COM Port, or Paired Mode connections. The 10/100 Mbps Ethernet connection auto-selects 10BaseT or 100BaseTX and indicates the type of connection with a bi-color link light.

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 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.

•Virtual COM Driver Software for Windows - installs a virtual COM port, viewable in the Windows Device Manager under Ports (COM & LPT). Virtual COM port provides access to any of the ports on the 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 Mode

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.

Virtual COM Mode

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.

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.

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 Virtual COM Port Mode or with Paired Connection Mode. 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 Virtual COM Port Mode and Paired Connection mode. This is not available when using a UDP application.

Serial Port Operational Modes

Using the ESP Manager or the Console Mode Configuration Menu each serial port can independently be configured as RS-232 Mode, RS422 Mode 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.

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.

Note:

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.

In Console Mode the default serial port settings are: 9600 baud, 8 data bits, No parity, and 1 stop bit. From Windows, HyperTerminal with VT100 terminal emulation can be used for Console Mode configuration.

Note:

Refer to Chapter 9 for details on Console Mode

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.)

Note:

Refer to Chapter 8 for details on Upgrade Mode
