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 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. 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.

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 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 Serial
Server, 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.

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.

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.

•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 RJ-
45 (male) Ethernet cable. To connect directly to an RJ-45 Ethernet port on a
PC or laptop a crossover Ethernet cable must be used.
