VLINX ESR90x Industrial Ethernet Serial Servers allow connection of RS-

232, RS-422 or RS-485 devices to an Ethernet network. The serial ports can
be accessed over a LAN/WAN using

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. 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.

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

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

Ports (COM &

computer. Any program running on the computer and using Windows­based COM ports can access the serial devices attached to the

Server. The LAN becomes transparent to the serial device and the

Serial

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
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.

Serial Server. The data is sent directly

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

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

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.

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.

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.

Gateway fields become inaccessible and cannot be changed by the user.

NNoottee::

A dynamic address assigned by the DHCP server may change if the server
loses the Ethernet connection or power is removed. The host (client)
communication software requests a connection to the specific IP address of the
serial server. If the DHCP reassigns a different IP address the software will not
be able to communicate with the hardware. Therefore, using a static IP address
is recommended.

IP Address

Software or hardware attempting to access the Serial Server via the network
must know the

default IP address of the Serial Server is printed on a label on its bottom
cover. Entering an appropriate address in the IP Address field and updating
the server will change the server’s IP address. The network administrator can
assign/establish the static address or group of addresses to be used.

The IP Address of the Serial Server can be confirmed using the DOS Ping
command.

Link Status

Link status automatically displays the type of Ethernet connection. It will
either display 10BaseT or 100BaseTX in full duplex or half duplex. This will
depend on the LAN, switches, hubs used in the LAN topology.

Server Serial Port

This field indicates the number of the port for with Serial Server properties
are currently being displayed. Changing the number in this field will cause
all the other fields to display the properties for the specified port. Note,
however, that before changing ports, any changes to properties must be

Updated (Saved) or the n will not retain them.

NNoottee::

Select None when setting the port as RS-485 or 4-wire RS-422.

TCP/UDP Protocol

Select TCP (Transmission Control Protocol) or UDP (User Datagram
Protocol) protocol. If the application does not require a UDP connection,
select TCP. TCP guarantees reliable communication with error checking
whereas UDP provides faster transmission.

UDP Mode

When UDP mode is chosen the Serial timeout, TCP alive timeout,

Connection mode, Connection at, Max connection and Remote
IP address fields are replaced with the following four fields:
Destination IP address range, Port number and Source IP
address range. In this mode the server can be configured to

Force Transmit

This field allows the user to set a maximum time limit between transmissions
of data. The value set in this field multiplied by 100 ms determines the Force
Transmit time. When the elapsed time reaches the time configured in this
field, the TCP/IP protocol will pack the data currently in the serial buffer into
a packet and send it out the Ethernet port.

Port Status

This field indicates whether a serial port is connected via the Serial Server to
a virtual COM port of a device on the network.

TCP/UDP Port

This sets the port number for connection. The default port number for the

ESR901 serial port is 4000. The default port numbers for serials ports 1, 2, 3

and 4 are

4000, 4001, 4002 and 4003 respectively.

In all modes of operation,
the Server Properties menu must match the Virtual COM or socket software
port settings.

NNoottee::

Example: The Virtual COM default setting is TCP/UDP Port 4000. If the port #
property is changed to 4001, the virtual COM port will have to be changed to

4001. The hardware settings can be changed from the ESP Manager or
Console Configuration Menu. The Virtual COM port setting also can be
changed within the Device Manager of the computer on which it is installed.
