1 Introduction
The Quatech DSE-410D Dual-Port Ethernet Serial device server provides Ethernet to
Serial connections for RS-232, RS-422, or RS-485 devices. The serial ports can be
accessed over a LAN/WAN using “Direct IP Mode”, “Virtual COM Port”, or “Paired
Mode” connection. The 10/100 Mbps Ethernet connection auto-selects 10 BaseT or
100 BaseTX and indicates the type of connection with a bi-color link light.
Features
Dual Serial Ports –One Multi-Interface Selectable
(RS-232, RS-422, or RS-485), and One RS-232
10/100 Mbps Ethernet with Auto Selection
LAN and WAN Communications
Configurable as TCP or UDP Client or Server
Device Driver Support – Windows 98/ME/NT/2000/XP
Includes Quatech DSE-410D Manager Software for Windows
Includes Virtual COM Driver Software for Windows
Selectable Heart Beat Connection
Firmware Download for Future Revisions/Upgrades
The Heart Beat Connection ensures reliable communications in Virtual COM port
mode or with paired connections. This feature restores the connections if
communications are temporarily lost at either end due to loss of power or the Ethernet
connection.
The Quatech DSE-410D Manager Software provides easy configuration of Ethernet
and Serial port settings. For configuration, the DSE-410D can be attached to your
network using a standard Cat 5 Ethernet cable, or to the Ethernet port of your
computer using a crossover cable. If a network connection is not available, the DSE410D can be configured in Console Mode from an RS-232 port, using a VT100
Terminal Emulation program and an RS-232 crossover cable. HyperTerminal is
included with Windows and is recommended.
The DSE-410D Virtual COM Driver installs a virtual COM port which is viewable in
the Windows Device Manager under “Ports” (COM & LPT). This virtual COM port
provides access to one of the ports on the DSE-410D the same as 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 DSE-410D. The LAN becomes transparent to the serial device and the software
running on the PC.

Communication Modes
The DSE-410D enables communication with serial devices over a LAN or WAN.
Serial devices are no longer 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 will allow 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 DSE-410D. In this type of
application the DSE-410D is configured as a TCP or UDP server. The socket program
running on the PC establishes a communication connection with the DSE-410D. The
data is sent directly to and from the serial port on the server.
Virtual COM Mode
Use Install Virtual COM to add a driver that provides 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 such Virtual ports. When a
program on the PC opens the new COM port, it connects to the remote serial device
connected to one of the ports on the DSE-410D.
DSE-410D
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 an IP packet, sends it across the network to the DSE-410D,
which converts the IP packet back to serial data and sends the data out the serial port.
To use this mode, the DSE-410D must be set to either TCP/server or UDP/server in
the menu with a designated communication port number. The virtual COM driver is
the TCP or UDP client.

Heart Beat Connection
The Heart Beat Connection provides an extra measure of reliable communications
assurance in Virtual COM Port Mode or Paired (Tunneling) Mode. This feature
restores the TCP connection if communication is 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 attention to correct the problem. 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 5 seconds until communications is established again.
The Heart Beat feature is not available when running in UDP Mode.
Quick Start
This section lists the steps needed to start using the DSE-410D.
Please familiarize yourself with the connections, indicators and switches before
beginning. See chart and diagram on page 7.
There are three ways to configure the DSE-410D for your network and serial devices.
We recommend the first method if using a Windows operating system.
1. Ethernet connection using the Quatech DSE-410D Manager under Windows
2. Ethernet connection using the Telnet VT100 Terminal software
3. RS-232 connection in Console mode using VT100 Terminal software
The DSE-410D can be configured on your network using a standard Cat 5 Ethernet
cable, or to the Ethernet port on your computer using a crossover cable. Use the DSE410D Manager utility with Windows or use Telnet for configuration without Windows.
With Console configuration, an RS-232 Crossover (null modem DTE/DTE) cable is
usually needed, as the DSE-410D ports are configured DTE for RS-232. Set the mode
switches to Console mode, (SW 1 - ON, SW 2 - ON, SW 3 - ON) before configuration.
Step 1: Decide which method to use for configuration and operation.
If using the Console mode for setup, refer to the Console mode section, Chapter 9,
and Chapter 5, then power up the DSE-410D.

Quatech, Inc. - 5675 Hudson Industrial Parkway, Hudson, OH 44236 – 330.655.9000
http://www.quatech.com
Step 2: Attach the DSE-410D to your network’s switch or hub using a standard Cat 5
Ethernet cable, or directly to the LAN port on your computer using a crossover cable.
You can connect your serial devices now if needed.
If using Telnet for setup, refer to the Console mode section, Chapter 9, and
Chapter 5, then power up the DSE-410D.
Step 3: If using Windows, install the Quatech DSE-410D Manager software on the
configuring Computer.
Step 4: Power on the DSE-410D and check the status lights.
Step 5: Start the Quatech DSE-410D Manager from your program menu.
Step 6: Select Search to find the DSE-410D on your network.
Step 7: When found, Double-Click the DSE-410D to bring up the Server Properties
Configuration Screen. If more than one DSE-410D shows up, select the one that
matches the Default IP Address shown on the bottom of the DSE-410D (usually
192.168.0.1).
Step 8: Refer to the Server Properties section, Chapter 5 for details on the
Configuration parameters for each field. Configure and then Save/Update.
Step 9: If you want to use Virtual COM ports with Windows, install the Virtual COM
port or ports on each computer requiring access to the DSE-410D.

RS-485 Mode
The RS-485 mode supports the Transmit and Receive Channels using 2-wire halfduplex operation. The data lines are differential with the Data B line positive relative
to Data A in the Mark state. Ground provides a common mode reference. Refer to the
Pin-out table for connections.
Selecting Internal RS-485 Bias Resistors
You can select RS-485 Receiver Biasing from the DSE-410D if your network doesn’t
supply any. Remove the two side cover screws, slide the cover off, then set the two
bias jumpers (shown open) to enable biasing (shorting).
RS-422 Mode
The RS-422 mode supports 4 channels with full duplex operation for Receive,
Transmit, RTS (Request To Send) and CTS (Clear To Send). The data lines are in
differential pairs with the B lines positive relative to the A lines. Ground provides a
common mode reference. To use handshaking, Flow Control must be set to RTS/CTS
during configuration. Refer to the Pin-out table for connections.
RS-232 Mode
The RS-232 mode supports eight channels plus Signal Ground and is configured as
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. Refer to
the Pin-out table for connections.
Default Setting
Use this mode to reset the original factory default settings when powered on.

http://www.quatech.com
Upgrade Mode
You can install newly revised firmware for the DSE-410D using RS-232 connections
from a PC, through either the DSE-410D Manager or through the Virtual COM port.
See Chapter 8 for details.
Console Mode
The Console mode provides access to the configuration menu using RS-232
connections. Connect a null modem crossover cable between the Multi-Interface port
and one of the computer’s RS-232 serial ports. The DSE-410D Serial ports are wired
as DTE, like a computer, using DB9M connectors, so a crossover cable must be used
to connect to another DTE port.
In Console mode the default serial port settings are: 9600 baud, 8 data bits, No parity,
and 1 stop bit. With Windows, you can use HyperTerminal with VT100 terminal
emulation for Console mode configuration. Use the default settings only if they have
not been changed during a prior installation/configuration. See Chapter 7 for details.

RS-422 Connections
In the RS-422 mode, TXD lines are outputs and RXD lines are inputs. Connect the
TXDB(+) line to the RXDB(+) line of your device, and the TXDA(-) line to the
RXDA(-) line of your device.
If Flow Control is set for RTS/CTS, connect the RTSB(+) line to the CTSB(+) line of
your device and RTSA(-) to CTSA(-) of your device. Connect from CTSB(+) to
RTSB(+) of your device and from CTSA(-) to RTSB(+) of your device.
If connecting to Receive Only RS-422 devices, connect from TXDB(+) and TXDA(-)
to the receive pairs on all your devices.
Ground is signal ground and provides a common mode reference for the RS-422
Receiver and Transmitters.
The RS-422 mode can be used for full duplex 4-wire RS-485 operation provided that
the DSE-410D is acting as a sole master connecting to all the slave devices, and all
slave devices share the Receive signal lines to the master. Set Flow Control for none,
and omit connections to RTS/CTS line pairs.
