About Your LWS40xA Wireless Serial Server

LWS40xA Wireless Serial Servers are part of Black Box growing family

of device servers, products that allow you to connect equipment with
available serial connections into existing networks. LWS40xA wireless serial
servers connect RS-232, RS-422 or RS-485 devices to a wireless network via
wireless access points, eliminating the need for network cabling. Devices
connected to the serial ports on your LWS40xA can be accessed from any
node on the LAN using Direct IP Mode, Virtual COM Port, or Serial
Tunneling (Paired Mode) connections. Based on the 802.11g wireless
standard, LWS40xA servers operate at up to 54Mbps over the 2.4 GHz band,
which does not require licensing.

Communication Modes

LWS40xA Wireless Serial Servers enable communication with serial
devices over a wireless network. The three main types of communications
supported by LWS40xA Wireless Serial Servers are Direct IP Mode,
Virtual COM Mode and Serial Tunneling Mode.

Direct IP Mode

Direct IP connections allow applications using TCP/IP or UDP/IP socket
programs to communicate with the asynchronous serial ports on the serial
server. In this type of application the serial server is configured as a TCP or
UDP server. The socket program running on the PC establishes a
communication connection. The data is sent directly to and from the serial
port on the server. When using UDP protocol the server can be configured to
broadcast data to and receive data from multiple IP addresses.

Virtual COM Mode

Virtual COM Mode allows application programs to effectively extend their
COM ports across the network. Data sent to that port is redirected via the
network to a COM port on the serial server. Windows programs using
standard Windows API calls are able to interface to these virtual COM ports.
When a program on the PC opens the port, it communicates with the remote
serial device connected to one of the ports on the serial server.

After connection, the LAN is transparent to the program and serial device.
Applications are able to work just as if the serial device is connected directly
to a physical COM port on the computer. The virtual COM port software
converts the application’s data into IP packets, sends it across the network to
the serial server, which converts the IP packet back to serial data and sends
the data out a serial port located on the serial server.

Serial Tunneling Mode

Serial Tunneling is also called paired mode. In this mode any two serial
devices that can communicate across the wireless link will be able to
communicate using two serial servers.

One server is configured as a TCP or UDP client and the other as a
TCP/UDP server. When setting up the server the remote IP address section
must contain the address of the client. This will allow the client’s IP address
to pass the IP address-filtering feature of the server. Conversely, the Remote
IP address of the client must contain the server’s IP address. Both
communication port numbers must be the same.

802.11 Wireless Networking Basics

LWS40xA wireless serial servers allow you to connect non-network-

enabled serial devices into a wireless network, giving you the capability to
gather more data and implement remote programming and management.
Serial devices no longer are limited to a physical connection to a PC. The
serial device can be connected to a LWS40xA wireless serial server
anywhere within range of an 802.11g compatible wireless access point.
Communication occurs transparently using TCP/IP or UDP/IP over a
wireless link. This allows traditional Windows PC software access to serial
devices anywhere on the wireless network.

The enabling technology for LWS40xA wireless serial servers is based on
the IEEE 802 standard. Some background on the standard follows.

802.11 Wireless Networking

IEEE 802.11 is a set of standards that defines how multiple devices can
communicate on a wireless network. The standard has grown into a set of
several standards that define various features and functions. The 802.11g
standard defines the physical and data link layers for a wireless network
using the 2.4 GHz frequency band, a band that does not require licensing. As
a part of the IEEE family of standards, 802.11 WLANs are easily connected
to 802.3 (Ethernet) LANs. Higher layer LAN protocols, network operating
systems and internetworking protocols such as TCP/IP integrate seamlessly.

Under the IEEE 802.11 standard there can be two different types of devices
on the wireless network: stations and access points (AP). A station often is a
PC equipped with a wireless network adapter. An 802.11 access point is a
radio with an interface that allows connection to a wired LAN. Access points
run bridging software to facilitate the connection from wireless to wired
network. The access point becomes the base station for the WLAN. It
aggregates access to the wired network for multiple wireless stations. An
access point may be a standalone device or a card in a PC.

Wireless Network Configurations

The 802.11 standard defines two modes of operation: infrastructure mode
and ad hoc mode. Infrastructure mode makes use of one or more access
points connected to a wired LAN. Wireless stations communicate with access
points to gain access to each other and/or the LAN. In the Basic Service Set
(BSS) several stations communicate with one access point, which is
connected to a wired LAN. In the Extended Service Set (ESS) two or more
access points connect to the LAN creating a subnetwork.

In ad hoc mode, also called Independent Basic Service Set (IBSS), access
points are not used. Wireless stations communicate directly with each other
in a peer-to-peer fashion. This mode allows individual computers to set up a
network where wireless infrastructure does not exist.

LWS40xA wireless serial servers can be configured to operate in
infrastructure mode only, ad hoc mode is not supported at this time. During
device configuration a wireless configuration wizard guides you through the
process of setting up the type of network, naming the network (specifying the
SSID, or service set identifier) and other parameters.

IEEE 802.11g

IEEE 802.11g standard specifies a WLAN that operates on the 2.4 GHz band
at data rates up to 54 Mbps, but is backward compatible with the earlier

802.11b standard (which operates at up to 11 Mbps). Systems can
incorporate 802.11b and 802.11g equipment and they will interoperate.
However, when connected into the same network the 802.11g equipment will
operate at the 11 Mbps limitation of the 802.11b equipment.

For media access, 802.11 wireless networks use CSMA/CA, a scheme in
which a station that intends to transmit ‘listens’ for traffic on the radio carrier
frequency and sends data packets if the frequency is clear. If the receiving
station receives the packet intact it sends an acknowledgement (ACK) to
confirm the packet has been received. If the transmitting station does not
receive an ACK it assumes a collision occurred and transmits again after a
random delay period.

Communications distances vary depending on the type and thickness of
material around an 802.11g node. The transmitter power output, the type of
antenna used and the amount of attenuation through materials also affects the
useable range. Electromagnetic noise, reflections, the amount of network
traffic, other radio devices operating in the same frequency band also affect
range and overall performance. In an infrastructure network the number of
access points and their coverage pattern also affect how well the system
operates. Typically an 802.11 device operating indoors will have a range
from 100 feet minimum to about 300 feet maximum. Outdoors, some
products, using high gain antennae may achieve line-of-sight ranges of five
miles or more.

Security is a significant concern for WLAN users. Whether security threats
originate intentionally or unintentionally, wireless systems are more
susceptible than wired systems. LWS40xA offer several security options
including WEP (Wired Equivalent Privacy), LEAP (Lightweight Extensible
Authentication Protocol) and others.

RS-485 Receiver Biasing

LWS40xA wireless serial servers provide built-in receiver biasing on RS­485 ports (includes the LWS406A 485 port, LWS402A Port 2 and
LWS404A Ports 2 and 4). The Data(+) line is pulled up to 3.3V supply using
a 4.7 kΩ resistor and the Data(-) line is pulled down to ground, also using a

4.7 kΩ resistor.

RS-422/485 Terminating

If a terminating resistor is deemed necessary, for RS-422 operation typically
a 120 Ω resistor would be connected across the Receive Data(+) and Receive
Data(-) lines. For RS-485 operation the resistor would be connected across
the Data(+) and Data(-) lines.

There is a significant difference between serial and Ethernet data communications.
Data that comes in through the Ethernet is presented to the device in the form of very
distinct packets. On the other hand without information about the format of the data
coming in through the serial port the device may not know at what point to package
up the data and hand it off to the Ethernet network. It is for this reason that the
LWS40xA series of devices allow you to define when the device converts serial
stream data into Ethernet packets. The following examples are provided to illustrate
the power behind these options:

Configuration #1: The LWS40xA is connected to a device used to monitor air
temperature. Software that interfaces with this hardware polls the device for the
current status once a minute. This data is returned in the form of a single byte
containing the temperature in Celsius.

Configuration #2: This LWS40xA is connected to a machine is connected to an
ATM machine. When a customer starts a transaction with the ATM a large burst of
serial data is passed onto the central bank.

Obviously in both of the configurations the data is critical and needs to be passed over
the network in the quickest manner possible. For configuration #1 the best behavior
for the device would be to send the incoming byte of temperature information out over
the network as soon as it comes in. On the other hand if the device acted the same way
for the second configuration it would flood the network with all of the Ethernet
overhead. In this case the device would be better to wait for a moment and send a full
Ethernet packet rather than a packet for each byte of data.

There are a number of different conditions that your LWS40xA can be configured to
watch for when dealing with the data coming in through it’s serial communication
port(s).

• Polling Strings

• Timeouts

• Data Quantities

Polling Strings

Polling strings are used when you want the LWS40xA to look for a specific data
pattern before taking the data in it’s serial buffer and creating an Ethernet packet with
it. Polling strings can be configured to monitor not only the serial traffic but the
Ethernet traffic as well.

Timeouts

Polling strings are used when you want the LWS40xA to look for a specific data
pattern before taking the data in its serial buffer and creating an Ethernet packet with
it.

There are two different types of timeouts. Total Message and Inter-character timeouts.
A Total Message timeout counter starts when the first byte is received. Once the
specified amount of time has elapsed since this initial byte the trigger is fired and the
device will transmit the buffered data.

The second type of timeout is an Inter-character timeout. This is used to trigger after a
defined amount of inactivity.

Data Quantities

In addition to the two previously mentioned methods of Ethernet packet transmission
triggers you can also setup a specific data amount that the device will wait for before
acting on the incoming data.

Using Multiple Conditions

You can use the data trigger conditions individually or it is also possible to use them
in combination with each other. When more than one condition is specified they are
treated as a “logical AND”. This means that if any of the conditions specified is true
then the data buffer is transmitted.

Device Detection Utility

To find devices on a wireless network, run the Device Detection Utility. This
program will be installed in the start menu at Black Box\Tools.

To use, click “Scan For Devices”. The software will send a broadcast and all
devices on that subnet will be displayed in the list. The device will be displayed
with a friendly name and the IP Address that it was found on.

A typical scan would look something like this:

After completing a network scan, use the IP Address to browse to the Web Server
to configure the device.
