Quatech SDS User’s Manual Introduction

Introduction
Quatech’s line of Serial Device Servers (SDS) is designed to networkenable any device currently using RS-232 or RS-422/485 serial
communications protocols. Our Device Servers provide industryleading 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:
Note: For on-line technical
support, see Quatech’s Web site.
A typical scenario:
You 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.
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.
¾ Remote support – support personnel can diagnose and repair
many problems by communicating with your serial devices via the
Internet or Intranet.
¾ Remote management – install new firmware or software upgrades
on your serial devices without physically removing them from
service.
¾ Efficient communications – instead of having one device
communicating with one computer, your device can communicate
with any computer on the network.
¾ Wireless freedom – Wi-Fi-enabled Device Servers provide serial-
to-wireless connectivity to your network.
¾ 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!
¾ 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!

Introduction Quatech SDS User’s Manual

Understanding how virtual communication ports work
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.
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 networkbased 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
Note: You can find the unit’s
Ethernet (MAC) address on the
product information label
located on the bottom of the
unit.
Assigning an IP 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
Quatech’s Unique product
unique identifie
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:
¾ Through the Installation Wizard for initial configuration
¾ Through the Web interface for reconfiguration and maintenance
identifier
Page 2 940-0183-153 July 2005
Quatech SDS User’s Manual Introduction
Using Port numbers
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.
Identifying operating modes
Normal mode
Note: Normal is the standard
connection mode for an SDS.
Tunneling mode
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.
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.
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.
Note: In Tunneling, a master
sends out the configuration
information to a slave so that
the slave can communicate
with it.
Raw TCP mode
Note: You could use Raw TCP
if you were running a simple,
custom TCP application.
Auto TCP mode
Note: Auto TCP is the only
communication mode that lets
an SDS initiate the connection.
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.
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 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:
¾ It receives serial data (Data mode).
¾ 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
July 2005 940-0183-153 Page 3
Introduction Quatech SDS User’s Manual
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
Note: Raw UDP can provide
one-to-many communications.
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:
¾ Multicast (transmits to specified group of recipients)
¾ Broadcast (transmits to unspecified recipients)
¾ Point-to-Point (transmits to one recipient)
Identifying Quatech’s SDS product line
Quatech provides a family of SDS products. SSE-100, DSE-100, QSE100, 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 RS422/485 communications. For convenience, this manual refers to all
these products as SDS unless otherwise noted.
Table 1 - SDS models
Note: All models are available
with surge suppression as an
–SS option. For example, the 4port RS-232 unit with DB-9
connectors and surge suppression
would have a part number of
QSE-100D-SS.

Note: SDS products with a “W”
in their part numbers (such as
SSEW-100) implement Wi-Fi
technology. They provide serialto-wireless communications in
addition to all standard SDS
functions.
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 supplied 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

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:
¾ Security system alarm/access control devices
¾ Industrial computers and sensors
¾ Point-of-Sale (POS) peripherals
¾ Time clocks
¾ Banking peripherals and ATM machines
¾ Medical equipment
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:
¾ Network addressing, routing, and data block handling: IP
¾ Network communications: TCP, UDP, DHCP, HTTP, and ARP
¾ Network management: SNMP
SNMP Network management support
The Simple Network Management Protocol (SNMP) agent running on

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 Webbased interface (see page 43).
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:
¾ Network manager – One or more workstations used to monitor
¾ Managed system – Composed of managed devices on the network
¾ Management Information Base (MIB) – Standard organization
Note: SNMP is used to
communicate status updates
and parameter values between
a remote device such as an
SDS and a network manager.
¾ Network management protocol – SNMP is a set of rules governing
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.
Note: The SDS is a read-only
device. You cannot set any
parameters via SNMP.
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

Introduction Quatech SDS User’s Manual
Note: Traps are messages or
alarms generated by an SNMP
agent to indicate to the SNMP
manager that a significant
event has occurred.
Wi-Fi implementation
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.
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, 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.
¾ 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 and WPA security protocols can encrypt
data to protect it during transmission from the SDS to an AP.
¾ 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™
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.
Page 6 940-0183-153 July 2005
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.

connecting to the SDS is turned off.
Step 2 Connect a serial cable between the SDS
and your serial device.
Step 3 Connect an Ethernet cable between your
Ethernet outlet and the SDS’ 10/100 port.
Step 4 Insert the power source jack into the
power plug on the back of the SDS.
See Serial port(s) on page 10 for pinout
and connector information.
The Ethernet port is located on the back
panel.
An SDS requires a 5-VDC, 2-A (10-W
max) power source. The power source
ships with the SDS.
Note: These are the available power cables:
920-0111-01A Std North America
920-0112-01A Std Continental Europe
920-0113-01A Std United Kingdom
920-0114-01A Std Australia
Step 5 Plug the power source into a wall socket. The SDS powers up automatically.
Step 6 Power up the serial device. Now you are ready to install the device
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
low green when your wireless
SDS finds and communicates
with another device.
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
the device drivers
on page 16 and Setting network parameters on page 47.

Use a CAT5 or better Ethernet cable to attach
the SDS.
When the SDS is ready, the Status, Power,
and Link LEDs should glow.
You will need this address for the network
configuration.
The Quatech Device Server Home page
displays.
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: The Channel setting is only used in Ad hoc
mode. In Infrastructure mode, the AP determines
the channel.
Step 11 Press Submit to configure the SDS with
your settings.
Step 12 Reset the SDS. Click on the link to perform a remote reset,
