AirStream Technology
Overview
Reliability , security, range, and cost have been the traditional obstacles to widespread adoption of wireless data networks. But today frequency hopping technology provides reliability comparable to and security greater than wire. AirStream T ranscei vers ha ve been designed specifically for long range and low cost. Moreover, the license-free band at 2.4GHz allows wireless data connectivity solutions to be implemented without site licenses or carrier fees. These developments make wireless data networks more practical and affordable than wire for many applications.
AirStream wireless data connectivity solutions are more reliable, more secure, longer range, and lower cost than wire:
More Reliable
AirStream Transceivers evaluated with industry standard test equipment have exceeded a bit error rate (BER) standard 100 times more rigorous than for 10 BaseT Ethernet and 1,000 times more reliably than cellular devices.
More Secure
AirStream Transceivers utilize frequency hopping technology developed by the military and refined by intelligence agencies to avoid interception and interference. It is more difficult to intercept communications between AirStream wireless devices than to tap a wire.
Longer Range
AirStream Transceivers operate through walls and floors up to 1,500 feet in most buildings, and line-of-sight to the horizon outdoors. For longer distances, networks of AirStream Transceivers can relay data packets to and from out-of-range devices to significantly extend the range of a wireless data network.
Lower Cost
Wireless devices are installed at prices that can be a fraction of the cost of wires. AirStream devices can be moved or reconfigured at no additional cost.
AIRSTREAM T ECHNOLOGY
AirStream uses Frequency Hopping Spread Spectrum (FHSS) technology to ensure secure, reliable long-range data transmissions. AirStream utilizes this proven technology to provide OEMs and Systems Inte grators with a superior wireless data connectivity solution for many industrial and commercial applications.

AirStream Technology
Overview
Frequency Hopping Spread Spectrum technology was developed by the U.S. military to prevent interference or interception of radio transmissions on the battlefield. Frequency hopping devices concentrate their full po wer into a very narrow signal and randomly hop from one frequency to another within that spectrum up to 200 times per second. If they encounter interference on a particular frequency, the devices retain the affected data, randomly hop to another point on the spectrum, and continue transmission. There are always spaces without interference somewhere in the allotted radio spectrum. A frequency hopping device will find those spaces and complete a transmission where other wireless technologies fail.
AirStream Transceivers operate in the license-free Industrial, Scientific, and Medical (ISM) band at 2.4GHz. No one owns or licenses these frequency bands. Consequently, anyone may operate a wireless network in a license-free band without licenses or carrier fees (unlike cellular technology), subject only to restrictions on how much power can be used (1 watt or less in the U.S.) and the type of radio signals transmitted (spread spectrum). The U.S. FCC and telecommunications regulators in many countries have designated this band for low-power license-free use.
Speed and Bandwidth
There is a common misconception regarding speed and data connectivity; specifically, that faster is better. In computer and telecommunications networks, higher speeds are unquestionably superior . Ho wever , this is not the case with wireless data connectivity. There are many circumstances where range, in-building penetration, and reliability are more important than speed.
Paying for more speed than what is necessary to implement a data connectivity application is not efficient. The broader radio frequency (RF) bandwidth needed to transmit higher data rates dramatically reduces range. In contrast, the lower data rates used by AirStream allow narrow bandwidths to be used. This is ideal for intermittent, repetitive data transfer, where the premium is on accuracy and long-range transmission. AirStream products have been designed specifically to meet the requirements of such applications. A lower data rate enables AirStream Transceiv ers to operate within a narro w RF band o ver significantly longer ranges than other 2.4 GHz Frequency Hopping or Direct Sequence Spread Spectrum (DSSS) products.

AirStream Technology
Overview
Sessions and Links
AirStream Transceivers use demand-based frequency hopping where RF is only transmitted when there is data available to transmit. The initiating transceiver is termed the master and the recei ving transcei v er is called the slave. Any device (host or remote transceiver) can be a master or a slave depending on who initiates the data transfer. AirStream Transceivers transmit data using sessions and links. A session represents a complete data transfer cycle between two devices. The session lasts as long as it takes to transfer all of the data being sent. A session can be comprised of a number of links which represent the actual transfer of data between two devices. Radio interference can break a link but not end a session. It may take several links to complete a session. If a link is broken, it is the job of the master to reinitiate the link in order to complete the session. This strategy reduces the collision rate of packets and RF interference from adjacent devices.
Data going in and out of the transceiver via the serial port is (or can be) a continuous stream of information; whereas, data transmitted over the air is broken into frames. Links consist of these frames. The frame represents the physical data packet transmitted per hop between units.
The transceiver’s channel access (communications link) is based on the Carrier Sense Multiple Access (CSMA) protocol. This protocol has the advantage of requiring no special coordination between remotes and works best with a large or variable number of remotes transmitting infrequent bursts of data. Channel latency is exponentially distributed, meaning there is a wait cycle during interference. During interference, data is hopped to another frequency. Although there is a slight delay during each hop, data is not lost.
Error Detection and Correction
AirStream Transceivers provide CRC error correction, forward error correction, and transmission retry to ensure complete transmissions, even in the most demanding circumstances.
The transceiver uses the ITU cyclical redundancy code 16 (CRC-16) for error detection. Two separate CRC-16 checks are used within each packet frame:

AirStream Technology
Overview
Most wireless systems experience single bit errors as the most common type of reception error. Forward Error Correction (FEC) can be used to correct for a specific number of bit errors within x -number of bits transmitted. AirStream uses a ‘Half Rate Coding’ algorithm which achieves a correction rate of 1 bit-error in 4 bits transmitted.
The transceiver maintains data integrity over the air by means of an internal automatic-repeat-request (ARQ) protocol, which will resend erroneous data until it is received correctly. The transceiver takes user data and breaks it into packets which are then transmitted at a much higher channel data rate. If the received packet has errors and is not correctable via the forward-error-correction (FEC) algorithm, the packet is rejected and resent until a valid packet is received. The transceiver maintains two 4kB buffers (transmit and receive) which helps to support continuous uninterrupted transfers even in noisy situations. See Broadcast Network on page 22 for details on how Broadcast Network behavior differs.
Transmit Power Control
Wireless devices in close proximity often experience desensing or over­loading. AirStream Transceivers minimize this problem by providing adjustments in the Power Level Feed-Back Control Loop based on the time-averaged Received Signal Strength Indicator (RSSI) values and the Actual Power Level Setting as shared between both devices during a communication session.
Data T ransfer Sessions
All units are in one of six possible sequential modes or phases of operation which cover the complete cycle of data transfer.
Idle
Unit listens and scans in each of the 75 channels in the hop table. No activity.
Link Acquisition
Data is present locally , unit be gins to ping (search) each frequenc y in hop table to find the remote unit.
Synchronization
Units on both ends of data transfer synchronize their hopping patterns.

Security
Overview
SECURITY
Data Transfer
In-sync units each alternate transmitting and receiving data in 32msec intervals (32msec Tx, 32msec Rx). Each 64 msec they hop to the next frequency.
Exit Phase
Data transfer is complete based upon the setting for number of frames of No Data specified in the transceiver’s configuration.
End Connection
Data transfer is complete, units return to Idle mode.
Frequency hopping is inherently more secure than other RF technologies. In addition, each AirStream Transceiver has a Vendor ID set in the firmware shipped straight from the factory. As you configure each transceiver you may provide additional network ID numbers and assign varying hop tables for independent networks. The combination of firmware, software IDs, and frequency hopping technology ensures safe and secure data transmissions. AirStream Transceivers also support your data encryption software.

TRANSCEIVER FEATURES
AirStream Transceivers enable OEMs and Systems Integrators to integrate license-free 2.4GHz frequency hopping technology into their own products. Each transceiver includes a proprietary RF module with a frequency hopping transmitter and receiver, a Digital Control Module for RF Module and Application Interf ace management, and an interface (TTL or RS232) designed to communicate with a variety of products. The AirStream Transceivers employ a wireless interface designed to function as a virtual wire replacement.This offers some distinct advantages over wire. AirStream Transceivers:
Enable mobility that may not have been possible before. And using
either the RS232 or RS485 serial connection, the transceivers can connect devices at long range—up to 1500 feet indoors, and line of sight to the horizon.
Compensate for baud rate differences between devices, eliminating
the need for converters between older, slower devices and newer, somewhat faster ones.

SERIAL COMMUNICATIONS
In order to configure any transceiver, you must use a 9 pin RS232 cable. This is necessary because pin 4 is used to transmit the configuration data into EEPROM and other pins are used during the configuration process as well. AirStream provides a 9 pin RS232 cable with all Stand-alone Transceivers. A TTL to RS232 pin adapter is purchasable for Design-in Transceivers.
You must use the 9 wire cable in the following cases:
When using the Conguration Manager to initialize/setup a
transceiver.
When the Host PC is using network utilities.
When eld upgrading the transceiver.
Once configuration is complete, you may opt to use a 3 or 5 wire cable during field communication with Stand-alone transceivers. These cables are not provided by AirStream. They can be purchased from a number of sources.

9 Wire Connection All 9 pins are connected.
2. Determine whether you need a straight through or null cable.
The interface between the transceiver and the attached device is a Data Communications Equipment (DCE) or Data Terminal Equipment (DTE) connection requiring either a straight through or Null cable. The Null cable (or Null adapter) simply crosses the required pins to allow similar devices to communicate properly (e.g., DCE to DCE). In general:
• The AirStream Transceiver is always a DCE device.
•A PC is typically a DTE device.
• Remote devices (customer equipment) can be DCE or DTE depending on the device.
• DCE to DTE communications require a straight through cable.

Antennas
ANTENNAS
Antennas must be connected to each transceiver for proper operation. Without an antenna, two units will not communicate. The higher the gain of the antenna, the longer the range of the transceiver signal.
AirStream Transceivers are designed to be used only with certain antenna products. AirStream offers the omni-directional antennas listed below as compliant with FCC Certification for the transceiver. The AirStream Transceiver uses a unique mechanical connection (reverse thread SMA connector) for all external mount antennas to ensure that only compliant antennas are used with the transceiver . AirStream does not endorse the use of omni-directional antennas other than those listed below.

Chapter 3: Point to Point and Network T opologies
AirStream Transceivers support Point to Point Pairs and several Network topologies. Each AirStream Transceiver can be configured via its Configuration Manager to work in any of these topologies. The transceiver’s Configuration Manager controls how the transceiver transmits and receives data as connected to the device. The operation of the transceiver in the network topology is determined by its Network Software Utility.
POINT TO POINT PAIR
In a Point to Point topology, AirStream Transceivers are used to connect two devices (e.g., a bar code reader and a printer), or a PC with a single remote device. The

NETWORKS
Wireless data connectivity applications require a wide range of networking options. The AirStream Network topologies consist of more than two transceivers and may have a PC to host a network of devices. The host and network devices are each physically attached to a AirStream Transceiv er.
The following Network topologies may require Network Software Utilities. The required utilities are listed within each topology description and explained in detail in “Network Software Utilities” on page 23. Depending on the topology and network utility combination you select, some of the Transceiver Features on page 6 may not apply . This is e xplained for each topology.

assign GPIO mode to any remote on the network, the host must also be assigned GPIO mode. The Host has a GPIO register so it can detect which remotes are using GPIO.
Repeater Network
AirStream Transceivers in a Repeater Network function similarly to a Multi-Point Network. They expand the range of the Multi-Point Network by relaying data packets between otherwise out-of-range remote devices and a Host PC. The effecti ve transmission rate for data packets for de vices beyond direct connection with the host is reduced by one third. Data can be transmitted between as many as 238 remote devices and a Host PC. The transceiver connected to the Host PC transmits and receives data from any transceiver one at a time. Sessions may be initiated by any device on the network. Devices can be dumb (accept data directly without recognition) or intelligent (recognize data transmission on a network and grab what applies).
The most significant advantage of a Repeater Network is the ability to extend range. This is advantageous when you have some remote devices that are not within direct range of the host. This network extends range in

layers. These layers may overlap but you cannot go beyond 4 layers of range. Data travels through a single path to the receiving transceiver. This network works well in environments where you do not need to communicate large amounts of data but need to communicate over long range. In the diagram below there are four layers. Data is sent from the host through a path consisting of D, G, J, and M. This is the single path used to get the data from the host to M as M is out-of-range of the host.

The AirStream Broadcast Network has two modes of operation; Remote

B
In Remote To Host, transmissions by remote units can only be
received by the host.
In Remote To All, transmissions by remote units can be received by
C
D
every other unit in the network that is within range.
Unlike other AirStream Network topologies, in Broadcast there is no session established between the units engaged in communication. This means that transmitted data is not acknowledged by the receiving side. If, for example, there is a momentary signal blockage at the receiving unit location, the affected receiving unit will miss any data transmitted during the signal blockage. Although signal impairments could cause data “drop­outs” any data received over the wireless link is still checked and corrected (if possible) by the AirStream error detection/correction process. This ensures that data is error free.
Broadcast mode is especially useful to applications where you must transfer the same information to all units at once or where a polling protocol is employed to collect data from remote units. In polling applications, the sending transceiver sends a query message to each remote unit in turn, asking for any data that the remote unit has available. The remote unit then has a chance to send its data to the polling transceiver. In a typical polling arrangement, each remote must wait until it is queried by the sending transceiver before transmitting. In this way collisions between transmissions of more than one remote unit are avoided. If, when polling a number of remotes, a reply is not received within a predetermined time interval the sending transceiver can retransmit its query or simply move on to the next query on its list.
Broadcast mode is intended primarily to be a RS485 network wire replacement. It is especially useful in adding new equipment to older (legacy) systems where there is a 2 wire or 4 wire RS485 connection. The
irStream User’s Manual
22
4 wire connection is replaced with the Remote to Host mode and the 2 Wire connection is replaced with Remote to all mode. The AirStream RS232 to RS485 converter is needed to configure AirStream Transceivers for RS485 devices.
Note: The Broadcast Network does not support GPIO, data thresholding, or
power management and asymmetrical data rates are lower. Flow control was not intended for use in this topology.
Note: The sending transceiver’s link light will only turn on if a remote is
sending data. The remote transceiver’s link light will always be lit when synchronized on the network. The sending transceiver is always transmitting; however, other AirStream Networks will work when collocated with a Broadcast Network as long as their hop table assignment is different.
NETWORK SOFTWARE UTILITIES
Each network topology is supported by a combination of a Configuration Manager which allows you to configure each individual transceiver for your network topology and a variety of available Network Software Utilities which allow you to arrange data transmission in your network. Although summarized here, usage of each of these utilities is described in detail throughout this manual.

only be receiving data and will wake up when it is needed to deliver incoming data to the printer. The transceiver attached to the bar code reader will only be sending so it can sleep until awakened by the reader when it needs to send data to the printer. It is possible to conserve power usage in this manner without sacrificing efficiency of data transfer.
To change power modes
1. Click the Special Features tab.
2. Click the desired Power mode.
Mode Explanation
Normal Unit operates at full power. LED is a constant light. Sleep Unit will enter a Sleep mode with minimal power requirements.
The unit will not wake-up until data appears locally on the unit’ s serial port for transmission. During Sleep mode reception of data from another unit is not possible. This is practical for battery applications and other low power requirements. LED on unit will slowly blink on and off when unit is in Sleep mode.
Doze Unit will cycle the receiver on and off (at a 50% duty cycle).
Data can be received from another unit or transmitted from the local unit during the Doze mode. Response time in receiving data from another unit may be slightly longer than under Normal power. LED on unit will blink very rapidly when the unit is in Doze mode.

USING HOP TABLES
A Hop Table is a listing of frequencies in a given spectrum that are used for communication. Data is sent to each frequency in the table in a hopping pattern. Hop Tables provide improved security and the ability to avoid localized noise sources. There are 100 possible Hop Tables in your transceiver (this number may vary for international transceiver models). These are subdivided into five completely independent, non-overlapping Hop Table sets, each with no more than three consecutive frequencies. Each individual network can only utilize one Hop Table.
Entering Hop Table Numbers
Hop Table numbers can only be entered or changed by using the Quick Configuration wizard.

Validating the Hop Table
Specifying Hopping Parameters
This command verifies the integrity of the Hop Table stored within the transceiver. The Hop Table in the transceiver is compared to the Hop Table with the same number in the Configuration Manager database. The Advanced Settings tab provides the selected Hop Table number and whether the Hop Table has passed validation and the first and last indices used for the Hop Table. Index values are set to meet the requirements of the country in which the transceiver is deployed for a minimum number of hop frequencies. These values can not be changed to avoid violating country regulations. To validate the Hop Table, from the Commands menu, select Validate Hop Table.
You can customize Hop Table parameters by setting some features available from the Advanced Settings tab.
Max No Data
Max No Data is the number of hop cycles that must pass during which no data was received and no data was available for transmission before a session can be declared down. It is used as the trigger to end a session. After a certain number of Frames No Data between both units, the master will terminate the current session/link.
Max Bad Hop
Max Bad Hop is the number of data frames with errors received before a link is considered bad. This is the trigger to stop the current link and wait for a random standoff period (~0.5 to 3 seconds). This is due to the assumption that after 4 (system default but can be changed) consecutive bad hops, the link has been lost — either due to interference or lost synchronization. By waiting a small amount of time before attempting to reestablish the link, the obstruction (i.e., noise source) may have moved somewhere else.

SERIAL SETTINGS
The Serial Settings tab allows you to select the serial port, baud rate, flow control, data bit size, parity, and stop bits settings. Each side of the communication link need not have the same serial settings. Serial Settings can also be entered via Quick Configuration. These settings are how the transceiver communicates with the device attached to it.
Setting Explanation
Port The particular serial port number to be used. The default setting
is COM1.
Baud Rate Speed of the serial connection for the device to which the
transceiver will be connected. Available options: 300, 600, 1200, 2400, 4800, and 9600 full duplex and 14,400 and 19,200 for asymmetrical data transfer. The asymmetrical rates will automatically default back to 9600 full duplex during periods of peak bi-directional data exchange. The default setting is 9600. For a Host transceiver the setting must be 9600. Supported values are: 600, 1200, 2400, 4800, and 9600.

Setting Explanation
Flow Control A method of temporarily suspending the flow of data between
two devices. Available options: None, Hardware (RTS/CTS) or Software (Xon/Xoff). The default setting is None. Software flow control is not available for a Host transceiver. Flow control is a means of temporarily suspending the flow of data between two devices. The most popular methods are called hardware and software flow control. Hardware flow control uses the RTS/CTS lines. Software flow control uses special characters, often called tokens (Xon/Xoff) to achieve the same result. Hardware flow control is typically the more common of the two methods. When using asymmetrical data rates, hardware control should be used to ensure data buffers are not ov erfilled which can result in a loss of data. Supported values for Flow Control are: None, Hardware, or Software.
Data Bits Represents the number of bits within each piece of data.
Available options: 7 or 8. The default setting is 8. A host transceiver must be set to 8.
Parity Traditionally used as a method of detecting data errors. A v ailable
options: None, Odd, Even, Mark, or Space. The default setting is None. A host transceiver must be set to N.
GPIO Mode When enabled this allows for a General Purpose Input and
Output pin to be assigned on the RS232 connector (e.g. RTS & CTS). This provides additional benefit for contact closure applications such as opening/closing, turning on/off, notifying when specific events have occurred. When this function is enabled, Hardware Flow Control will be automatically disabled.
NOTE: You must assign control lines in your network utility software for GPIO mode to take affect.
Stop Bits Available options: 1 or 2. The default setting is 1. A Host
transceiver must be set to 1.
Supported combinations for Data Bits, Parity, and Stop Bits are:
Note: When setting up a Host device within a Network setting, the configuration
program will automatically preset the serial parameters to: 9600, 8, N, 1. These settings are required for the Network Software Utility to ensure the best possible data transfer speeds.

Configuring Y our Transceiver
This feature allows a predetermined time to elapse or amount of data to accumulate before a data transfer session is initiated. It is accessed through the Special Features tab.
Setting Explanation
Time A number (from 1 to 65,535) will specify the number of
100msec increments that must elapse between the initial receipt of data (locally) before a data transfer with another transceiver is initiated. This will provide up to 109 minutes of time that data can accumulate before a transfer. The time must be set to ensure that no more than 4K (the size of the data transfer storage buffer) of data collects before a transfer occurs. If the buffer were to fill up before a transfer, all additional data would be lost.
Size Up to 4096 bytes of data can be collected before a data transfer is
initiated.

ComPort Intercept™ is a Windows communication driver (software application) that intercepts all RS232 traffic and automatically reroutes it to/from the host transceiver. It allows up to 16 transceivers to be

• ComPort Congurator
• ComPort Activator
• Virtual Ports
•Physical Ports
The Host PC must be running a Microsoft W indo ws 95 or 98 operating system. ComPort Intercept allows the host transceiver to be configured to provide the network management functions. It can have multiple applications on the host communicating through the virtual ports at the same time. It can be used for Multi­Point or Repeater Network topologies.
This chapter discusses the configuration of the small network. It assumes that the ComPort Intercept software has been correctly installed.
ComPort Intercept consists of two components which are designed to hook into Windows serial communication traffic and transparently reroute the data through a Multi-Point or Repeater Network. The Configurator component is used to configure the Windows System Registry, by creating virtual communications devices. The Activator component is the actual loader/driver that will run in the background of the operating system and capture any configured serial data traffic and reroute it to the assigned remote transceiver and application program.
The host transceiver needs to be assigned to a physical communication port (typically COM1 or COM2). Virtual ports are created and assigned a remote Unit ID which corresponds to a particular remote transceiver’s Source ID Number thereby creating a logical association between each virtual COM port number and a remote transceiver within the network.
AirStream User’s Manual

ComPort Configurator
Setting up a Network with ComPort
Note: The ComPort Intercept program will work with various client programs
that communicate via COM ports (e.g., HyperTerminal) with serial rates of greater than 115K baud. While "over the air" data rates are effectively 9600 full duplex, the ComPort Intercept process will buffer data to each application according to its particular requirements. Internal buffer space for each virtual port is 8K Bytes.
Note: You can not activate ComPort Activator if any other application is
currently using the Physical COM port that has been configured for the host transceiver on the network (e.g., Configuration Manager).
COMPORT CONFIGURATOR
Microsoft Windows requires that all physical and virtual ports be registered within the System Registry for proper operation. ComPort Configurator is used to create and configure virtual ports and assign them to the host.

driver may be used for Windows NT as well as Windows 95/98 and above.
You can use any Windows compliant compiler, however, the examples provided in the following functions are specific to Visual C++, Visual Basic, and Visual J++. The sample code placed on your system during installation is also based on these three compilers. These files have been modularized to emphasize the unique properties of each of these compilers and the various system calls. Please use these examples as your instructional material for creating an application template. They are located in C:\Program Files\Zeuswireless\Samples. These samples include a simple Host to Multi-point application, a ping application, a background printing function, and complex example that incorporates all of these. This chapter provides the entire ActiveX API.

Chapter 8: T esting Your Units
You can test the operation of transceivers in a variety of ways using the Configuration Manager. The instructions in these chapter assume that the Configuration Manager is correctly installed and the transceiver is properly connected to your PC. These tests include:
Terminal mode
Loopback test (Stand-alone model only)
TERMINAL MODE TEST
The Terminal Mode tab provides a simple terminal interface from which data can be sent between two units configured as a Point to Point Pair. Anything typed in the input field of transceiver 1 will immediately be transferred to transceiver 2. The data is displayed in the transmit pane for transceiver 1 and the receive pane for transceiver 2. (Note you will only see received data if the destination transcei ver is connected to a PC with Configuration loaded and open or if the destination PC’s transceiver has a loopback connector.)

Test Operation
57. Connect transceivers 2 and 3 to peripheral devices. Note power supply,
connector, and antenna connections must all be made.
Transceiver 1 must remain connected to the Host PC.
58. Send data from the Host PC to a peripheral device.
For example, if you had a printer (with a serial connection) that you have been using (i.e., drivers are already set up) you could write a short memo in a word processor on the Host PC and select File>print. The information would be printed out on the printer just as if it had been connected by wire. This would work for any existing wired connection on a local LAN.
Another example would be to use HyperTerminal. This requires that your peripherals are also PCs or that you use a loop back connector to see the data sent returned in your HyperTerminal Window.
