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.

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:
o VLINX 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).
Web Server allows configuration via the network using
o
any web browser.
o
Telnet allows configuration via the network by accessing
the setup configuration menu.
o
Console 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
Introduction
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 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
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 packet back to serial data and sends the data out a serial port located on the
Serial Server.

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

To use this mode, the

Serial Ports
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.

RS-422 Mode
When
Default Mode is selected and the server properties are Updated
(
Saved) all the configuration settings return to their default values.
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 Console Mode configuration.
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.

Refer to Chapter 5 for details on Serial Server Configuration settings. See Chapter 12 for Serial Server default parameters.

Refer to Chapter 9 for details on Console 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
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.
NNoottee::
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.

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.
