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!

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.
RS-232 Device

DSE-100 2 DSE-400
QSE-100 4 QSE-400
ESE-100 8 ESE-400
RS-232/422/485 Device
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 Quatech World Wide Web site at

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.
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.

Enabling Wi-Fi Device Servers
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.
