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 – WiFi-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 2 940-0183-155 April 2008

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. Use the SDS’ web interface to
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

April 2008 940-0183-155 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 WiFi
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
Quatech World Wide Web site at http://www.quatech.com/

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

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 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.

WiFi implementation

Note: WiFi 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 WiFi communications.

See Enabling WiFi 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.

WiFi, short for wireless fidelity, allows WiFi-enabled devices to
connect to an Ethernet/Internet network without cables or wires. You
can use a WiFi network to connect these devices to each other, to the
Internet, and to wired networks. WiFi is a fast, powerful, reliable,
and secure alternative to wired communication.

Quatech’s WiFi-enabled SDS devices provide serial-to-wireless
network connectivity. They enable you to connect to and communicate
with your serial devices over 802.11b/g 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 WiFi 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/g 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 6 940-0183-155 April 2008

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.

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 WiFi SDS units:

¾ Infrastructure = SDS is

associated with Access Point

¾ Ad hoc = SDS has found

device to communicate with

Note: If you press and
immediately release the Reset
button, the SDS restarts
automatically with no changes.
Also, if you continue holding
the Reset button longer than 20
seconds, the Status LED stops
flashing and no changes are
made.

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)

On = SDS is up and running

The Status LED also works in
conjunction with the Reset button
as follows:

1. To restore the SDS to the

factory default configuration,
push in and hold the Reset
button. When the Status LED
starts flashing slowly, and
before it starts flashing
rapidly, release the button.
The SDS then restarts
automatically.

2. To restore the SDS to the

factory default firmware
revision, push in and hold the

Reset button. When the Status
LED changes from a slow flash
to a rapid flash, release the
button. The SDS then restarts

If the Reset 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.

If the Reset 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

eriod, the SDS is reset back to the

factory default firmware revision.

Enabling WiFi Device Servers Quatech SDS User’s Manual

Enabling WiFi Device Servers

Note: WiFi Device Servers link
via an AP in Infrastructure
mode; they connect directly to
another device in Ad hoc mode.

Note: The Link LED on the
Ethernet port will glow green
when your wireless SDS finds
and communicates with
another device.

Quatech’s WiFi 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 802.11b/g 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 47.
