Introduction
Chapter 1: INTRODUCTION
VLINX ESR90x Industrial Ethernet Serial Servers allow connection of RS232, RS-422 or RS-485 devices to an Ethernet network. 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 autoselects 10BaseT or 100BaseTX and indicates the type of connection with a bi-color link light. ESR90x serial servers are built for use in industrial environments, featuring an IP30, approved slim line DIN rail mountable case. They operate from a range of AC or DC power supply voltages, support redundant DC power and feature terminal block power connectors.

Introduction
oAll ports are software selectable as RS-232, RS-422, RS-485 full duplex or RS-485 half duplex interfaces
oFor all models Port 1 is software, or DIP switch selectable for Console Mode operation (configuration via direct serial connection)
•Slim line DIN rail mountable case
•Accepts AC or DC power over a wide volt range
•Redundant DC power supply input
•10/100 Mbps Ethernet with Auto Selection
•LAN and WAN Communications
•TCP or UDP Client or Server operation - configurable
•Software Support - Windows 98/ME/2000/2003/XP/ NT 4.0 and Vista
•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 a 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 RS232 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 Serial Server, like any other serial port (legacy, PCI, USB or PCMCIA) on the computer. Any program running on the computer and using Windowsbased 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 ESR90x 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.
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.

Introduction
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 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.

ESR90x Indicators, Switches and Connectors
Indicators
•One bi-color Link LED (Yellow = 10BaseT, Green = 100Base T)
•One green Ready LED (flashing = system ready)
•One red Power LED
•One red RX LED and one green TX LED for each serial port
Switches
Reset
A recessed reset switch that allows the united to be reset. Insert a small plastic tool, press lightly and hold for three seconds. The Link and Ready lights will go out and then come back on.
Run/Console Switch
A recessed single DIP (dual inline package) switch that allows the Serial Server to be switched between Run Mode and Console Mode. When switched to the Console position the Serial Server enters Console Mode. This allows you to configure the Serial Server from a PC running a terminal program such as HyperTerminal without connecting the server to the network. To communicate with the connected serial device the switch must be returned to “Run” position.
DB-9/Terminal Switch (ESR901 only)
Allows connection to the serial port (RS-232, 422 or 485) via the DB-9M connector or the five-terminal removable terminal block.
Connectors
Ethernet Connector
One standard RJ-45 receptacle that allows the Serial Server to be connected to an Ethernet hub, switch, or wall plate using a standard straight-through RJ45 (male) Ethernet cable. To connect directly to an RJ-45 Ethernet port on a PC or laptop a crossover Ethernet cable must be used.

Serial Server/Port Operational Modes
Using the ESP Manager, Web Server or Telnet the Serial Server can be put into Console Mode, Default Mode or Upgrade Mode. The serial ports can be configured for RS-232, RS-422, RS-485H (half duplex) or RS-485F (full duplex) operation. The server also can be put into Console Mode by placing the Run/Console switch in the Console position.

Making the 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 ESR901 serial port or ESR902/904 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.
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 ESR901 serial port or ESR902/904 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.

Making the 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.
RS-485H Mode
In RS-485H Mode the currently selected port is configured as a two-wire RS485 interface supporting DataB(+) and DataA(-) signal channels using halfduplex 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.
RS-485F Mode
In RS-485F Mode the currently selected port is configured as a four-wire RS485 interface supporting transmit lines TXDB(+) and TXDA(-) and receive lines RXDB(+) and RXDA(-) for full duplex operation. The lines are differential with the B line positive relative to A in the idle (mark) state. Ground provides a common mode reference.
RS-485 Receiver Biasing
RS-485 Receiver Biasing can be implemented from the Serial Server if the network does not supply it. Remove the four screws from the cover of the Serial Server, slide the cover off and re-position the bias jumpers as indicated in the diagrams and tables below. Note that ESR Serial Servers provide separate jumpers for RS-485 half duplex and RS-422/485 full duplex operation. Also, the ESR901 provides separate jumpers for the terminal block and DB-9 connectors. Biasing jumpers are also provided for CTS inputs.
