Introduction
Quatech’s line of Serial Device Servers (SDS) is designed to network-
enable any device currently using RS-232 or RS-422/485 serial
communications protocols. Our Device Servers provide industry-
leading hardware and user-friendly software to make connecting your
serial devices to an Ethernet network a surprisingly simple process.
There are many reasons to network your serial devices using a
Quatech Device Server, such as:
! Remote support – support personnel can diagnose and repair
many problems by communicating with your serial devices via the
Internet or Intranet.
! Remote management – install new firmware or software upgrades
on your serial devices without physically removing them from
service.
! Efficient communications – instead of having one device
communicating with one computer, your device can communicate
with any computer on the network.
! Wireless freedom – Wi-Fi-enabled Device Servers provide serial-
to-wireless connectivity to your network.
! Lower cost of ownership – no need to upgrade serial devices to
newer, costlier versions containing built-in Ethernet interfaces –
if such an upgrade is even available!
! Extended service life of software – your existing software can be
used to communicate with the serial device as if connected to a
local COM port; the network connection is “invisible” to the
application.
After following the simple steps included in the Quick Start Guide to
attach your network and serial devices to the appropriate connectors
on the Serial Device Server, you’ll need just a few more minutes to
install the driver. You’ll then be able to communicate with the serial
device via its own application software and with the SDS using a Web
browser!
To network-enable a serial device, plug it into the serial port located
on the Device Server. Plug in the network Ethernet cable and power
source, and load the Quatech device drivers onto a host PC anywhere
on the network, using the instructions provided. The Quatech device
drivers will install the SDS’ serial ports as if they were additional
local COM ports in Windows. Simply change the settings in the serial
device’s application software to look for the serial device on the new
COM port. It’s that easy!
A typical scenario:
Y
ou have a serial device
that is operated by a PC.
The application software on
the PC “talks” to the serial
device using COM port 3.
Unfortunately, anyone who
wants to communicate with
that device must come to the
local PC. This can be very
time consuming if the serial
device is located in a remote
area, and expensive if you
need a PC for every serial
device.
A
Device Server eliminates
the need for a local PC and
allows anyone with the
proper application software,
the Quatech Device Server
drivers, and authorized
access to the network, to
communicate with the serial
device.

Introduction Quatech SDS User’s Manual
Page 2 Rev 1.50 (3/13/2005)
Understanding how virtual communication ports work
Single port Device Servers allow you to network individual serial
devices such as printers, simple terminals, or medical monitoring
equipment that were previously accessible only via a direct link.
According to Dataquest, a Device Server is a “specialized network-
based hardware device designed to perform a single or specialized set
of functions with client access independent of any operating system or
proprietary protocol.” In terms of your new SDS, this means that you
can connect any serial device to your network by connecting the serial
device to a serial port on your SDS and connecting the Ethernet port
on your SDS to your network.
The SDS, once it has been correctly configured, makes accessing a
single serial device such as a time clock from your network a
transparent operation. This means that a PC can perform all the
operations in the same way it would if the serial device were plugged
directly into its serial port.
A network connection allows operation of serial devices at much
greater distances than can be accomplished with a direct serial
connection. Your SDS uses the TCP/IP protocol suite for network
communications. This means that communication through an SDS
can actually be more reliable than communication over long serial
lines, which lacks the advanced error checking built into TCP/IP.
Another benefit of accessing a serial device through an SDS is that
you can monitor and manage the device remotely, even from across
the world, if you have authorization and the network connection is to
the Internet.
Understanding MAC and IP addresses and port numbers
Identifying the Ethernet (MAC) address
Ethernet address, hardware address, and MAC address are all
equivalent names for a device’s unique network address. In the case
of an SDS, the first three bytes identify the unit as a Quatech
product. The last three bytes are unique to each unit and are
assigned when the unit is released from production. Colons separate
the bytes. The following is an example of an SDS Ethernet (MAC)
address:
00:0B:28:12:34:56
Assigning an IP address
Every device that communicates over the Internet must have a
unique IP address. You can assign an IP address to your SDS by
either of two methods:
! Through the Installation Wizard for initial configuration
! Through the Web interface for reconfiguration and maintenance
Note: Quatech Device Server
technology now allows access
to individual serial devices by
anyone with access to the
network on which they are
installed.
Note: Anyone in your organization
with a PC can connect to the
serial device over the network
just as though the two devices
were directly connected.
Note: A protocol is a set of rules
that notifies a transmitting
device and a receiving device
that the other is present and
ready to exchange information,
when the exchange is complete,
and whether it was successful.
Note: You can find the unit’s
Ethernet (MAC) address on the
product information label
located on the bottom of the
unit.

Using Port numbers
In order for devices to communicate via a TCP connection or a UDP
datagram, they must know each other’s IP address and port number.
The SDS driver automatically sets the unit’s port number for you.
A specific port number identifies each SDS serial port. An SDS
assigns a port number of 5000 to the first port, and then increments
the port number sequentially for each subsequent serial port. SDS
drivers must see the first port as IP address: 5000.
Identifying operating modes
Normal, Tunneling, Raw TCP, Auto TCP, and Raw UDP are all
different schemes to make a serial connection across a network using
one or more Serial Device Servers.
Normal mode
If you use Quatech’s virtual COM port drivers or the IntelliSock™
SDK (see TCP socket services – IntelliSock™ on page 6), you should
use the Normal mode to make your network connections. Normal
mode is used in the vast majority of applications. Unless you are
certain that you need to use a different mode, go ahead and configure
your SDS in Normal mode. This mode allows for complete software
control of the serial port by an application program.
Tunneling mode
Serial Tunneling allows two Device Servers and their Ethernet
TCP/IP connection to act like a direct cable connection between two
serial devices. No host computer is required.
Tunneling is very simple to use. Using the SDS’ web interface,
designate one SDS’ serial port as the tunneling master and the other
SDS’ port as the tunneling slave. Configure the master with the serial
port settings desired for the connection as well as the IP address of
the tunneling slave. The master makes the connection and automatically
configures the slave with the corresponding settings.
Raw TCP mode
In Raw TCP mode, serial port data travels over the TCP/IP
connection without any protocol wrapper. You must configure the
serial port settings using the SDS’ web interface. Raw TCP mode
works with most third party universal serial device server drivers.
Auto TCP mode
Auto TCP mode is a special case of Raw TCP mode that allows the
SDS to act as a network client and to initiate a TCP connection to a
network host. You can configure the SDS so that it makes the
connection in one of two possible instances:
! It receives serial data (Data mode).
! It sees that the DSR input is active (DSR mode).
As with Raw TCP mode, you must configure the serial port settings
using the SDS’ web interface. You must configure the SDS with the
Note: You can think of the IP
address as a telephone number
and the port number as a
telephone extension.
Note: This information is
useful for firewall configuration.
Note: Normal is the standard
connection mode for an SDS.
Note: In Tunneling, a master
sends out the configuration
information to a slave so that
the slave can communicate
with it.
Note: You could use Raw TCP
if you were running a simple,
custom TCP application.
Note: Auto TCP is the only
communication mode that lets
an SDS initiate the connection.
Introduction Quatech SDS User’s Manual
Page 4 Rev 1.50 (3/13/2005)
IP address and TCP port number of the network host to which it
should connect. If the SDS is idle, it will listen for normal Raw TCP
mode connections from the network host.
Raw UDP mode
Raw UDP is used primarily for broadcasting messages over a network.
It is lightweight and efficient; however, your application program
must handle all error processing and retransmission. Quatech
supports the following modes of UDP communication:
! Multicast (transmits to specified group of recipients)
! Broadcast (transmits to unspecified recipients)
! Point-to-Point (transmits to one recipient)
Identifying Quatech’s SDS product line
Quatech provides a family of SDS products. SSE-100, DSE-100, QSE-
100, and ESE-100 provide one, two, four, and eight RS-232 ports for
your serial devices, respectively. SSE-400, DSE-400, QSE-400, and
ESE-400 allow you to software-select between RS-232 and RS-
422/485 communications. For convenience, this manual refers to all
these products as SDS unless otherwise noted.
Table 1 - SDS models

SSE-100 1 SSE-400
DSE-100 2 DSE-400
QSE-100 4 QSE-400
ESE-100 8 ESE-400
Quatech’s SDS products all perform the same function (see notes),
differing mainly in the number of serial ports available or in the
serial protocol supported. All “D” models, which add a suffix of D to
the part number, (e.g. SSE-100D) are supplied with DB-9 connectors.
All “M” models, which add a suffix of M to the part number, (e.g.
QSE-100M) are not only supplied with DB-9 connectors, but also with
10-pin RJ-45 adapters that attach to the DB-9 connectors.
System requirements
Quatech’s SDS ships with device drivers for Windows 2000, Windows
NT4, Windows XP, and Linux. Other operating systems can access
the SDS using Raw TCP mode or the IntelliSock™ TCP socket
services. Quatech will provide reference materials and utilities to
assist those who wish to do so.
Contact our sales department for details on current software
offerings. Most device drivers are available for download from the
Quatech World Wide Web site at http://www.quatech.com/.
Note: All models are available
with surge suppression as an
–SS option. For example, the 4-
port RS-232 unit with DB-9
connectors and surge suppression
would have a part number of
QSE-100D-SS.
Note: Raw UDP can provide
one-to-many communications.
Note: SDS products with a “W”
in their part numbers (such as
SSEW-100) implement Wi-Fi
technology. They provide serial-
to-wireless communications in
addition to all standard SDS
functions.

Features
Quatech Device Servers can connect virtually any serial device to any
standard Ethernet network (Intranet or Internet) using TCP/IP
protocols. The following list details some of the serial devices an SDS
can bring to your fingertips:
! Security system alarm/access control devices
! Industrial computers and sensors
! Point-of-Sale (POS) peripherals
! Time clocks
! Banking peripherals and ATM machines
! Medical equipment
Protocol support
The SDS communicates over an Ethernet network using the standard
IP and TCP protocols to ensure data integrity and accurate targeting.
An SDS supports the following protocols:
! Network addressing, routing, and data block handling: IP
! Network communications: TCP, UDP, DHCP, HTTP, and ARP
! Network management: SNMP
SNMP Network management support
The Simple Network Management Protocol (SNMP) agent running on
your SDS collects network statistics such as the amount of data
transmitted and received, the number of frames that contain errors,
and the speed of the interface.
A network management system consists of these four parts:
! Network manager – One or more workstations used to monitor
and manage the elements comprising a network
! Managed system – Composed of managed devices on the network
running the agent process, such as an SDS
! Management Information Base (MIB) – Standard organization
scheme for storing data records; an SDS device with a firmware
revision of 5.0 and above supports MIB-II
! Network management protocol – SNMP is a set of rules governing
the exchange of management information between a network
manager and the elements of a managed system
The SDS supports MIB II, which is a standard set of statistics. It
includes information on system interfaces, address translation, IP,
ICMP, TCP, UDP, transmission, and SNMP group information.
For example, the agent running on the SDS collects network statistics
including the amount of data transmitted and received, the number of
frames that contain errors, the percentage of utilization of the
network, maximum packet size, speed, MAC address, and whether
the device is up and working. The agent provides a whole tree of
Note: Quatech Device Servers
capture data from legacy serial
devices without having to go
through a PC.
Note: Only SDS devices with a
firmware revision level of 5.0
and above can support SNMP.
To determine the revision level
of an SDS, check the bottom of
the Home page in the Web-
based interface (see page 43).
Note: The SDS is a read-only
device. You cannot set any
parameters via SNMP.
Note: SNMP is used to
communicate status updates
and parameter values between
a remote device such as an
SDS and a network manager.
Introduction Quatech SDS User’s Manual
Page 6 Rev 1.50 (3/13/2005)
information that a management network host can retrieve using the
Get command.
In addition to providing information upon request, the SDS supports
a cold start Trap, which is a spontaneous message the SDS initiates
whenever it boots up.
Wi-Fi implementation
Wi-Fi, short for wireless fidelity, allows Wi-Fi-enabled devices to
connect to an Ethernet/Internet network without cables or wires. You
can use a Wi-Fi network to connect these devices to each other, to the
Internet, and to wired networks. Wi-Fi is a fast, powerful, reliable,
and secure alternative to wired communication.
Quatech’s Wi-Fi-enabled SDS devices provide serial-to-wireless
network connectivity. They enable you to connect to and communicate
with your serial devices over 802.11b wireless networks. These units
all have a “W” incorporated in their names, such as SSEW-100 or
DSEW-400.
There are two access modes you can use with your Wi-Fi SDS,
depending on whether or not an access point (AP) is involved.
! Infrastructure uses an access point to link the SDS to other
network devices.
For example, an SDS connected to a POS device by a serial cable
will send and receive POS data through an AP to a wireless
network. Any PC connected to that network (either by a wired
connection or via an AP) can communicate directly with the POS
device. Optional WEP security protocol can encrypt data to
protect it during transmission from the SDS to an AP.
! Ad hoc directly links a SDS with another device without going
through an access point. For example, if you connect a security
camera’s serial port to an SDS, a wireless PC can connect directly
to the security camera through the SDS without ever going
through an AP.
Before an SDS can communicate on an 802.11b wireless network, the
WLAN settings must match those of the wireless network. By default,
an SDS is set to Infrastructure network mode and its wireless
Network Name (SSID) is blank, which will allow it to connect to any
available wireless network.
TCP socket services – IntelliSock™
The SDS implements Quatech’s IntelliSock™ TCP socket services.
Quatech supplies device drivers for Windows 2000, NT4, XP, and
Linux to make the SDS look like it is a built-in COM port.
IntelliSock offers you the option of interfacing directly to the SDS
through a TCP socket programming interface rather than using the
virtual COM port device drivers. IntelliSock can be used with any
operating system that supports TCP/IP communication.
Refer to the IntelliSock Software Developer’s Kit (SDK) folder on the
installation CD-ROM for documentation and sample code.
Note: Traps are messages or
alarms generated by an SNMP
agent to indicate to the SNMP
manager that a significant
event has occurred.
Note: Quatech’s IntelliSock™
provides the most flexible and
powerful TCP socket services
available for custom applications.
Note: If you do not need the
power of the IntelliSock interface,
the Raw TCP mode provides a
simple way of using a direct
TCP connection with the SDS.
Note: Wi-Fi is a wireless Ethernet
communication option.
Note: To setup the Wireless
SDS, you must first connect to
it in wired Ethernet mode to
obtain the IP address. Then,
use the Web browser to
configure the network settings
for Wi-Fi communications.
See Enabling Wi-Fi Device
Servers on page 14 for details
on installing and configuring
your wireless SDS.

Understanding LED codes
The SDS LEDs inform you of the communications status and activity
of the SDS. The following table lists the possible states of the LEDs
and their meaning.
Table 2 - SDS LED codes
LEDs Meaning
Link (green) On steady = connected to network
On steady for Wi-Fi SDS units:
! Infrastructure = SDS is
associated with Access Point
! Ad hoc = SDS has found
device to communicate with
Speed (amber) Off = 10 Mbps network connection
established if Link LED is on
On steady = 100 Mbps network
connection established
Data (red/green) Red = RS-232 connection
Green = RS-422/485 connection
Blinking = data activity
Status (green)
The Status LED also works in
conjunction with the Reset button
as follows:
On = SDS is up and running
1. To restore the SDS to the
factory default configuration,
push in and hold the Reset
(Default) button. When the
Status LED starts flashing
slowly, and before it starts
flashing rapidly, release the
button. The SDS then restarts
automatically.
If the Reset (Default) button is
held during the first 10 seconds of
bootup, the Status LED flashes at
a rate of 1 flash every 2 seconds
for 10 seconds. If the button is
released during this time period,
the configuration is reset to factory
defaults.
2. To restore the SDS to the
factory default firmware
revision, push in and hold the
Reset (Default) button. When
the Status LED changes from
a slow flash to a rapid flash,
release the button. The SDS
then restarts automatically.
If the Reset (Default) button is
held past the first 10 seconds of
bootup, the LED flashes faster at a
rate of 1 flash every second for 10
seconds. If the button is released
during this time period, the SDS
is reset back to the factory default
firmware revision.
Note: If you press and
immediately release the Reset
button, the SDS restarts
automatically with no changes.
Also, if you continue holding
the Reset (Default) button
longer than 20 seconds, the
Status LED stops flashing and
no changes are made.
Note: QSE-/ESE-100 units
have a Default button in
addition to a Reset button. If
you have one of these units,
hold the Default button (see
parentheses) and momentarily
press and release the Reset
button. Continue holding the
Default button as indicated.
Note: QSE-/ESE-100 units
have a green Speed LED.

Enabling Wi-Fi Device Servers Quatech SDS User’s Manual
Page 14 Rev 1.50 (3/13/2005)
Enabling Wi-Fi Device Servers
Quatech’s Wi-Fi Device Servers need to have a wireless network
connection established before they can be configured for use. To
enable the wireless connection, you need to obtain the SDS’ IP
address as outlined below. Once you have the IP address, you can
configure the SDS for wireless communications via the Web interface.
In Infrastructure mode, you can use your wireless SDS just as you
would a wired SDS, but it will communicate via an access point on
the 801.11b network rather than through an Ethernet cable. The SDS
will scan all channels until it finds an AP, at which time the Link
LED on the Ethernet port will glow green.
The following briefly describes how to obtain the IP address of the SDS
and to enable wireless communications. For greater detail, see Installing
the device drivers on page 16 and Setting network parameters on page 45.
Step Procedure Description
# Step 1 Turn on the power to your computer system.
# Step 2 Insert the Quatech SDS installation CD-
ROM into your CD-ROM drive.
If the CD-ROM does not launch
automatically, select Start – Run from the
Task bar, browse to the CD-ROM drive,
and select the ThinQ.exe file. Click “OK” in
the Run window to launch the
installation.
# Step 3 From the Main Menu, select Install SDS.
Click Next.
# Step 4 Connect the Ethernet port on your SDS
either to the NIC port on your computer or
to a switch/hub.
Use a CAT5 or better Ethernet cable to
attach the SDS.
# Step 5 Connect power to the SDS. When the SDS
is ready, click the Next button to search for
Serial Device Servers.
When the SDS is ready, the Status, Power,
and Link LEDs should glow.
# Step 6 When the search is finished, find your SDS
and make note of its IP address.
Press Cancel to abort the installation
procedure.
You will need this address for the network
configuration.
# Step 7 Open your Web browser and type the IP
address for the SDS in the Web browser’s
URL (address) field.
The Quatech Device Server Home page
displays.
# Step 8 Click on Network in the selection bar.
# Step 9 Select Infrastructure as the Access Mode.
# Step 10 Configure the Device Server’s SSID to
match the access point’s SSID.
To communicate wirelessly, the AP and
the SDS must both use the same SSID. If
you don’t know the proper SSID, check
with your system administrator.
Note: Wi-Fi Device Servers link
via an AP in Infrastructure
mode; they connect directly to
another device in Ad hoc mode.
Note: In Ad hoc mode, the Link
LED on the Ethernet port will
glow green when your wireless
SDS finds and communicates
with another device.
Quatech SDS User’s Manual Enabling Wi-Fi Device Servers
Rev 1.50 (3/13/2005) Page 15
Step Procedure Description

Win NT Device Manager
Windows NT does not provide a Device Manager; however, you can
use Quatech’s Device Manager to manage all the Quatech devices
installed on your machine. Double click the Device Manager (DM)
icon on your desktop to launch. Expand the Quatech Device Server
group at the bottom. Select your Device Server (SSE-x00, DSE-x00,
QSE-x00, or ESE-x00) and click Properties.
Four tabs display:
! General – information on device type, manufacturer, location, and
device status
! Driver – information on drivers used including location and
version
! Resources – COM port enumeration and first port number
! SDS Configuration – network information including MAS
address, IP address, subnet mask, and default gateway
The SDS Configuration tab will be the most useful to you. You can
differentiate between SDS units using the MAC address, which is
equivalent to the serial number. The IP number shows how this PC is
set up to talk to the SDS.
The Diagnostic Tools button runs a Ping test. Use the Web Interface
button to bring up the Web interface. See Configuring the SDS using
the Web interface on page 44 for details on using this interface.
Use the Advanced button to repair a broken connection. For instance,
if the SDS’ IP address changes and your DM can no longer find it, you
can search for the SDS and note its changed IP address.
Win NT – Changing port numbers
Click on the first port to see its designated port number. You can use
the DM to change the port numbers if necessary. Changing the first
port causes the others to change sequentially. See page 44 for details.

Configuring the SDS using a Web interface Quatech SDS User’s Manual
Page 44 Rev 1.50 (3/13/2005)
Configuring the SDS using the Web interface
This section explains how to configure an SDS using a standard Web
browser so that it can communicate over a network with a serial
device.
After the installation program included on the SDS CD-ROM is
finished, the Device Server will be ready for use as configured. If you
wish to make changes to the configuration at a future time, it is a
simple matter of entering the IP address of the Device Server into the
address bar of your computer’s Web browser.
Quatech recommends the use of Microsoft’s Internet Explorer for
accessing the Web browser-based configuration utilities built into our
Device Servers. Other browsers can be used but be aware that we
have not tested the many alternative browsers available, so some
graphics and page formatting could be misaligned.
The SDS stores its configuration in nonvolatile memory (Flash),
which is retained even when the unit is turned off.
Once you have installed the drivers on your computer and established
an Ethernet connection with the SDS, you can maintain and configure
the SDS using a Web interface.
Using a Web interface, you can:
! Configure the network settings (static vs. DHCP; if static, you can
set the IP address, Gateway address, and Address mask)
! View and set the serial port parameters (set per serial device
application; setup lets you set data rate multiplier, performance
mode, heartbeat timer, operating mode and operating mode settings)
! Perform diagnostic tests (Ping test, view port status list)
! Perform administrative functions (view, add, or remove users,
give the SDS a descriptive name, upgrade software, and perform
a remote reset)
! Contact Quatech corporate headquarters, sales, and technical
support
Follow these steps to manage your SDS using a Web interface.
Step Procedure Description
# Step 1 Open your Web browser. We recommend Internet Explorer 5.0 or
higher.
# Step 2 Type the IP address for the SDS in the
Web browser’s URL (address) field.
The format for an IP address is http://
followed by a series of numbers
separated by periods, such as
http://123.456.789.123.
The Quatech Serial Device Server Home
page displays.
Note: We have eliminated the
need to use console ports, DOS
shell commands, Telnet and
other complicated methods of
configuration. Just enter the IP
address after the HTTP://
prefix in your Web browser’s
Address bar, click Go, and you
are ready to reconfigure the
Device Server remotely!
Note: Wi-Fi units must have
their parameters configured
before they can communicate
wirelessly. See page 6 for Wi-Fi
information and page 14 for
configuration information.

Configuring the SDS using a Web interface Quatech SDS User’s Manual
Page 46 Rev 1.50 (3/13/2005)
Figure 44 - Network Setup screen
Step Procedure Description
# Step 1 Select between a Static IP address and
one set by the DHCP server.
For Static only, set the IP address.
This must be a unique address in your
network. Only let the DHCP server set
the IP address if it is configured to
always assign the same address to the
SDS; otherwise, the connection will fail.
Note that the SDS’ MAC address is
displayed. The MAC address is an
Ethernet serial number.
# Step 2 For Static only, set the Gateway IP
address.
The Gateway address must be within
your local network. It should be the
same as the IP address for the router
that is connected to the same LAN
segment as the SDS.
# Step 3 For Static only, set the Address mask. The Address mask is a string of 0's and
1's that screens out the network part of
an IP address so that only the host
computer part remains. Most people
select the Class C Address mask.
! Class A: 24 bits
! Class B: 16 bits
! Class C: 8 bits

# Step 4 For Wired Setup, go to □ Step 11.
For Wireless Setup, continue with
□ Step 5.
Before the SDS can communicate on an
802.11b wireless network, the WLAN
settings must match the wireless
network. By default, the SDS is set to
Infrastructure network mode and its
SSID, which is its wireless Network
Name, is blank. This allows it to connect
to any available wireless network.
# Step 5 Configure the SSID (network name).
The Service Set Identifier (SSID) is the
name assigned to your wireless network.
All devices on a wireless network must
be configured with the same SSID.
# Step 6 Select the Access Mode.
! Infrastructure (using the access point)
If using Infrastructure mode,
go to □ Step 8.
! Ad hoc (no access point)
If using Ad hoc mode,
continue with □ Step 7.
In Infrastructure mode, an AP bridges
or joins a wireless network (WLAN) to a
wired Ethernet network (LAN).
Ad hoc is a wireless communication
mode that allows all wireless devices
within range of each other to discover
and communicate with one another
Configuring the SDS using a Web interface Quatech SDS User’s Manual
Page 48 Rev 1.50 (3/13/2005)
Step Procedure Description
without involving central access points.
Devices communicating in ad hoc mode
do so in peer-to-peer fashion. All wireless
adapters on the ad-hoc network must
use the same SSID and the same
channel number.
# Step 7 For Ad hoc only, configure the Channel. As with the SSID, devices sharing a
wireless link must be tuned to the same
channel.
Note: The Channel setting is only used in
Ad hoc mode. In Infrastructure mode, the
access point (AP) determines which channel
all devices associated with it must use.
# Step 8 Enable or disable WEP.
! Select the Enable WEP checkbox to
enable WEP. Continue with □ Step 9.
! Clear the checkbox to disable WEP.
Go to □ Step 11.
An optional security protocol for wireless
local area networks, WEP provides
security by encrypting data over radio
waves so that it is protected as it is
transmitted from the SDS to the AP.
# Step 9 Select the Key Length.
! 64 bit
! 128 bit
Sets the WEP key length to be used.
Selecting 64 bit activates the top row of
hex number boxes.
Selecting 128 bit activates both rows.
# Step 10 Enter the WEP Keys in hex. These are two digit hex values that will
be used for the WEP keys. Valid
characters are 0-9, a, b, c, d, e, and f.
# Step 11 Press Submit to configure the SDS with
your settings.
Note: Press the browser’s Back button to make
no changes to the original settings.

Setting serial port parameters
In configuring your Serial Device Server’s serial port parameters,
there are two main considerations:
! Which operating mode should you use?
! Is your serial port RS-232 or RS-232/422/485 (MEI)?
Setting Normal operating mode parameters
This section explains how to set your RS-232 and RS-422/485 parameters
and also provides details on setting up your SDS in the Normal operating
mode. In the following sections, you’ll find information on configuring your
SDS for Tunneling, Raw TCP, Auto TCP, and Raw UDP operating modes.
In most cases, you will use the Normal operating mode for your SDS.
This allows you to use either Quatech’s virtual COM port drivers or the
IntelliSock SDK to communicate over a network.
Step Procedure Description
# Preliminary

Setting Tunneling operating mode parameters
Serial Tunneling allows two SDS units to create a virtual cable
connection between each other’s serial ports with one end configured
as a master and the other end as a slave. You set up the master with
the slave’s IP address and serial port number that you want use for
the virtual connection. The master finds the slave and makes the
connection. The master configures the slave’s parameters (baud rate,
parity, and so forth) as necessary. A master can connect either to an
SDS in Normal mode or to a slave in Tunneling mode.
On the slave end, all you have to do is click Slave and leave the rest of
the Operating Mode settings blank. The slave waits for a master to
connect to it and to provide the configuration parameters.
A master connects to one of a slave’s serial ports. A second master can
connect to another port on the slave at the same time. However, you
can only have one Tunnel master/slave combination working at the
same time between any single set of ports.

Setting Raw TCP operating mode parameters
Raw TCP mode allows an application to communicate with an SDS
without any custom protocol overhead. In this mode, the only data
sent over the TCP connection is that which will be sent or received
over the serial port.
An SDS port in Raw TCP mode cannot connect to an SDS port in
Normal mode because our Normal virtual COM port wraps the data
in headers before it transmits. In Raw TCP mode, you can’t send
down a packet that says change the baud rate; you have to set up the
serial port configuration yourself.
Raw TCP lets you write your own simple program to communicate
without having to put headers on the packet (no custom protocol
overhead).

That’s it! You’re done. Your SDS is
configured for the Raw TCP operating
mode.
Setting Auto TCP operating mode parameters
In Auto TCP, the SDS acts both as a client and as a server. As a
client, it connects to the server at the specified TCP address and port.
As a server, it will accept a Raw TCP mode connection.
You can configure an SDS port to use either DSR or Data to initiate a
connection. As with Raw TCP, you must configure all the connection
information (baud rate, data bits, and so forth) on the Serial Port
Setup page. There is no way for the application to tell the SDS what
to use for that serial port connection.
Auto TCP is also somewhat similar to Raw TCP in that only data
passes through an SDS serial port – there are no headers and no
packet. For this reason, you cannot use Auto TCP with our virtual
COM port drivers.
You can connect to the SDS via another host and use a port just as
you would in Raw TCP. The main differences between Raw and Auto
TCP are that Auto TCP operates in two modes (DSR and Data) and
that it can enable the SDS to initiate a connection.
! Auto TCP–DSR mode: When the SDS port sees DSR become
active (raised), it connects, on its own, to the end point specified
by the IP address and TCP port on the Serial Port Setup Web
page. When DSR is de-activated, the SDS drops the network
connection.
! Auto TCP– Data mode: When an SDS starts receiving data on its
serial port, it connects to the end point specified by the IP address
and TCP port on the Serial Port Setup Web page.
Auto TCP timeout: When a given amount of time passes
without any new data, the SDS closes the connection. The Auto
TCP Timeout is used only in Data mode, not in the DSR mode.
Note: Auto TCP is the only
communication mode that lets
an SDS initiate the connection.
Note: In Normal and Raw TCP,
an outside device such as a
computer performs the act of
connecting to the SDS. That’s
also one of the modes under
Auto TCP. A PC can connect to
the SDS and start transferring
data back and forth using its
serial port.
Note: Auto TCP settings must
include the baud rate, parity,
data bits, stop bits, and flow
control.

That’s it! You’re done. Your SDS is
configured for the Raw TCP operating
mode.
Setting Raw UDP operating mode parameters
Raw UDP is mainly used to broadcast messages over a network. It is
a connectionless protocol that offers a direct way to send and receive
datagrams over an IP network but provides very few error recovery
services. UDP applications must generally be willing to accept some
loss, errors, or duplication. Most UDP applications do not require
reliability mechanisms and may even be hindered by them. If your
application requires a high degree of reliability, you should use a
protocol such as TCP.
UDP provides no guarantees for message delivery and a UDP sender
has no way of telling the status of its messages once it sends them
onto the network. For multicast packages, unlimited propagation of
UDP packets through routers is prevented by the Time To Live (TTL)
scheme. Each router decrements a packet’s TTL value and only
forwards those packets whose TTL value is greater than the
threshold configured on the router.
UDP has three possible modes of communication that you select
according to the IP/UDP address you enter:
! Point to point – key in a specific device’s address to communicate
only with that device
! Broadcast – key in the broadcast address of 255.255.255.255 to
send to all devices listening for the transmission
! Multicast – key in an address in the assigned UDP range of
224.0.0.0 – 239.255.255.255 to send to several devices with the
selected address
Step Procedure Description
# Preliminary
Step
Select Serial Ports from the selection
bar.
Note: Setup screens vary slightly between
RS-232 and RS-232/422/485 (MEI) units.
If you have an RS-232/422/485 (MEI) SDS,
the Configure Serial Port Interface step will
display so that you can select between RS-
232 and RS-422/485 operation.
If you have an RS-232 SDS, the Configure
Serial Port Interface step will not display
and you will not be presented with any RS-
422/485 configuration options.
The Serial Port Setup screen shown on
the following page displays.
Note: Click on a link to see a pop-up help
screen for that item. For example, if you
click on the Raw UDP link, the following
help screen pops up.
Note: In Raw UDP, your SDS
can send messages to multiple
receivers simultaneously.

Step Procedure Description
# Step 1 Select the serial port you want to
configure.
Click on a port number to select that
port. The selections on the screen are
automatically populated with any
existing parameters for the selected port.
# Step 2 Click on the Raw UDP Operating Mode
selector.
Raw UDP allows an SDS device to
perform one to many transmissions.
You will find directions for configuring
ports in Normal, Tunneling, Raw TCP
and Auto TCP modes mode in the
previous sections.
Note: Click on a link
to see a pop-up help
screen for that item.
Quatech SDS User’s Manual Configuring the SDS using a Web interface
Rev 1.50 (3/13/2005) Page 67
Step Procedure Description
# Step 3a Configure the Operating mode.
Click on the desired data Rate Multiplier.
Your choices are:
! Auto (Recommended)
! Force X2 mode
! Force X4 mode
! Force X8 mode
The auto setting has no effect on the
baud rate you set. However, if you select
X2, X4, or X8, the baud rate of the serial
port will be the baud rate that you set
multiplied by 2, 4, or 8, respectively.
Note: Forcing a change in the data rate may
cause communication problems with some
serial devices. If this is the case, change the
setting back to Auto (Recommended).
# Step 3b Click on the desired Performance
Selector.
Choose balanced mode except in those
cases where the serial device cannot
tolerate the slight delays inherent in
normal TCP/IP operation.
Balanced mode offers excellent
performance for most applications.
Low Latency mode heavily favors
responsiveness over throughput.
# Step 3c Set the Heart Beat Time to a value from 1
to 65534 seconds. Default is 45 seconds.
Note: Use a value of 0 to disable the heartbeat
timer.
Heartbeat messages help detect when a
connection has been lost between the PC
driver and the SDS.
If you need quick notification that the
connection has been lost, set this timer to
a shorter value.
If you are more concerned about network
traffic, set this timer to a longer value.
# Step 3d Set the Baud Rate. The SDS and the serial device(s) to
which it is attached must use the same
serial connection speed.
# Step 3e Set the Parity. Parity can be odd, even, or none.
# Step 3f Set the Data Bits. Data Bits can be 7 or 8.
# Step 3g Set the Stop Bits. Stop Bits can be 1 or 2.
# Step 3h Set the Flow Control. Flow control determines the handshake
method used between the SDS and the
serial device(s) to stop the serial
input/output process
# Step 3i Set the UDP/IP Address.
These are your options:
! Multicast
! Broadcast
! Point to point
This selection determines the destination
IP address where data will be sent.
For multicast, enter a valid multicast IP
address (244.0.0.0 – 239.255.255.255) to
broadcast data to a specific multicast group.
For broadcast, enter 255.255.255.255 to
broadcast the serial data to all devices
ready to accept data.
For point to point, enter a specific
address to which the SDS can send UDP
packets containing serial data.

Step Procedure Description
# Step 3j Set the UDP port designation. Enter a valid UDP port number to which
the SDS can send. The SDS will receive
on both port 5000 and on the designated
serial port number.
# Step 3k Set the TTL value. This selection sets the TTL (Time To
Live) value for multicast packets. Each
router decrements the TTL value of the
packet and will only forward a packet if
its value is greater than the threshold
configured on the router. The following
are standard settings:
! 0 Restricted to host
! 1 Restricted to subnet
! 15 Restricted to site
! 63 Restricted to region
! 127 Worldwide
! 255 Unrestricted
Steps 4a through 4d apply only to RS-232/422/485 (MEI) units
# Step 4a
(MEI only)
Configure the serial port interface.
Click on the desired interface selector.
This series of steps only applies to MEI
units, such as the SSE-400.
If you select RS232, the RS422/485
selections will be grayed out. Continue
with □ Step 5.
# Step 4b
(MEI only)
Click on the desired duplex mode selector. Select Full Duplex to always enable
transmit and receive drivers.
Select Half Rx to only enable the
transmit drivers when the SDS is
transmitting; receivers always enabled.
Select Half Rx Tog to disable receivers
and enable the transmit drivers only
when the SDS is transmitting.
# Step 4c
(MEI only)
Click on the desired connector setup. Select Loopback All to internally loopback
RTS and CTS in the SDS. AuxIn and
AuxOut are looped at the connector.
Select Modem Control to send RTS on
the AuxOut signal and to receive CTS on
the AuxIn signal.
# Step 4d
(MEI only)
Select 2- or 4-wire communication. Select 2-wire to use the transmit pair for
both transmit and receive in RS-422/485.
Select 4-wire to use a separate pair of wires
for transmit and receive in RS-422/485.
Step 4 (non-MEI) / Step 5 (MEI) applies to all units
# Step 4
(non-MEI)
or
# Step 5
(MEI only)
Repeat the steps above for each port you
need to configure and then press Save to
implement all of your changes.
Close and re-open the port to activate
your changes. That’s it! You’re done.

FCC Notice: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
The user is cautioned that changes and modifications made to the
equipment without approval of the manufacturer could void the user’s
authority to operate this equipment.
It is suggested that the user use only shielded and grounded cables to
ensure compliance with FCC Rules.
Canadian Notice: This device complies with Industry Canada ICES-003 regulations.
Cet appareil est conformé à la norme ICES-003 du Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference, including interference that
may cause undesired operation of the device.
To prevent radio interference to the licensed service, this device must be
operated indoors only and should be kept away from windows to provide
maximum shielding.
This device has been designed to operate with an antenna having a
maximum gain of 2.2 dBi. Antennae having a higher gain are strictly
prohibited per regulations of Industry Canada. The required antenna
impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type
and its gain should be so chosen that the equivalent isotropically radiated
power (EIRP) is not more than that required for successful
communication.
The installer of this radio equipment must ensure that the antenna is
located or pointed such that it does not emit RF field in excess of Health
Canada limits for the general population.
