Introduction

Chapter 1: INTRODUCTION

VLINX Models ESP901 and ESP902 Ethernet Serial Servers provide Ethernet to Serial connections for RS-232, RS-422 or RS-485 devices. The ESP901 features a single serial port and the ESP902 features two serial ports. 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.

LAN and WAN Communications

TCP or UDP Client or Server operation - configurable

Software Support - Windows 98/ME/2000/XP or NT 4.0

Firmware Upload for future revisions/upgrades

Configuration of Ethernet and serial port settings can be accomplished using any of four methods:

oVLINX ESP Manager Software for Windows allows configuration via a network connection or directly from the Ethernet port of a computer (using an Ethernet crossover cable).

oWeb Server allows configuration via the network using any web browser.

oTelnet allows configuration via the network by accessing the setup configuration menu.

oConsole Mode allows configuration through an RS-232 serial port in using a VT100 Terminal Emulation program and an RS-232 crossover cable.

Virtual COM Driver Software for Windows - installs virtual COM ports, viewable in the Windows Device Manager under Ports (COM & LPT). Virtual COM port provides access to any of the ports on the ESP901 and ESP902, 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 Serial Server. 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.

Introduction

Communication Modes

The ESP901 and ESP902 Serial Servers enable 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 Serial Server. In this type of application the Serial Server is configured as a TCP or UDP server. The socket program running on the PC establishes a communication connection with the Serial Server. The data is sent directly to and from the serial port on the server. When using UDP protocol the server can be configured to broadcast data to and receive data from multiple IP addresses.

Virtual COM Mode

Install Virtual COM Mode allows the user 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 Serial Server.

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 Serial Server, which converts the IP packet back to serial data and sends the data out a serial port located on the Serial Server.

To use this mode, the Serial Server 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.

Introduction

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 Serial Servers and the LAN.

Two Serial Servers 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 addressfiltering 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.

Making Hardware Connections

DIP Switches

A triple DIP (dual inline package) switch allows the Serial Server to be placed into Console Mode. When all three switches are moved into the ON position the Serial Server enters Console Mode, allowing configuration of the Serial Server (using an RS-232 connection through the serial port on the ESP901 or Serial Port 1 on the ESP902) from a PC running a terminal program such as HyperTerminal. When the Serial Server enters Console Mode the Console Mode screen will appear in the HyperTerminal program window. The serial port settings must be 8-N-1 at 9600 baud.

Figure 7. The Console Mode (Server) Screen in the HyperTerminal Window

When any of the DIP switches are switched back to the OFF position, the Serial Server will revert to the mode it was in before Console Mode.

Note:

The Serial Server can be put into Console mode using either of two methods:

1.Switching all the DIP switches to the ON position

2.With any DIP switch in the OFF position set the Server Properties Console Mode field to Console and Update/Save the configuration

The ESP901 has one serial port. The port can be configured as a Console Mode connection or as an RS-232, RS-422 or RS-485 interface to the Serial Server (if any of the DIP switches are in the OFF position) using the ESP Manager software, via Telnet, or using the Web Server.

The ESP902 has two serial ports. Port 1 operates the same as the ESP901 serial port. Port 2 on the ESP902 is an RS-232 only interface.

The RS-232 interfaces are configured as DTEs. The connectors for all ports are DB-9M.

Console Mode

Making Hardware Connections

Default Mode

When Default Mode is selected and the server properties are Updated (Saved) all the configuration settings return to their default values.

Note:

Refer to Chapter 5 for details on Serial Server Configuration settings.

See Chapter 12 for Serial Server default parameters.

Console Mode

In Console Mode the Configuration Menu can be accessed from a PC by connecting its RS-232 serial port to the ESP901 serial port or ESP902 Serial Port 1. Since the computer is a DTE device, and the 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

configuration.

Note:

Refer to Chapter 9 for details on Console Mode

Upgrade Mode

In Upgrade Mode firmware can be uploaded from a PC via its serial port to the ESP901 serial port or ESP902 Serial Port 1. Upgrading also can be accomplished via the network connection, using the ESP Manager software and a virtual COM port.

Note:

Refer to Chapter 8 for details on Upgrade Mode

RS-232 Mode

In RS-232 Mode the currently selected serial port is configured as an RS-232 interface supporting eight RS-232 signal lines plus Signal Ground and is configured as a DTE, like a computer. Signals are single ended and referenced to Ground. To use handshaking, Flow Control must be set to RTS/CTS during Configuration.

Note:

Refer to Appendix A for RS-232 connection pin-outs.

Making Hardware Connections

RS-422 Mode

In RS-422 Mode the currently selected serial port is configured as an RS-422 interface supporting four RS-422 signal channels with full duplex operation for Receive, Transmit, RTS (Request To Send) and CTS (Clear To Send). The data lines are differential pairs (A & B) in which the B line is positive relative to the A line in the idle (mark) state. Ground provides a common mode reference. To use handshaking, Flow Control must be set to RTS/CTS during configuration.

Note:

Refer to Appendix B RS-422 connection pin-outs.

RS-485 Mode

In RS-485 Mode the currently selected port is configured as an RS-485 interface supporting transmit (TX) and receive (RX) signal channels using 2-wire, half-duplex operation. The data lines are differential with the Data B line positive relative to Data A in the idle (mark) state. Ground provides a common mode reference.

Note:

Refer to Appendix C for RS-485 connection pin-outs.

RS-485 Receiver Biasing

RS-485 Receiver Biasing can be implemented from the Serial Server if the network does not supply it. Remove the two side-cover screws of the Serial Server, slide the cover off and re-position the bias jumpers (shown open in the figure below) to enable biasing (shorting).

Figure 10. Internal Setting to Select RS-485 Bias
