BASIC ESTEEM PROGRAMMING

Most of the ESTeem commands outlined in this section have been
automatically input to the modem by the ESTeem Utility program.
A few of the commands used most often in troubleshooting and
programming are covered here. These commands can be
programmed to the modem directly by the Terminal Emulation
section of the utility or by any other terminal software package.

CHAPTER 1

STARTING OUT

HELP Functions

The ESTeem has over eighty software commands to aid the user in their application. The HELP command allow the user to list
the various software commands and their respective values.

From the COMMAND mode, type HELP<cr>. Your display should list the following:

Help switches are:

ALL (Lists all settings).
CHANGE (List settings changed from factory default).
CONTROL (List settings dealing with control).
PLC (List settings for PLCs).
RADIO (List settings for ESTeem radio).
RS232 (List settings for RS-232/422/485)
SETUP (List settings for control).
SYSTEM (List settings for system).

These are the different software categories.

Example: HELP SETUP<cr>, will list all the programmable variables and their settings for the SETUP category.

You can interrogate a discrete software command by just typing the command followed by a <cr>.

Figure 10: Test Radio Communication

Example: ADD<cr>, will list the current address saved in the connected ESTeem.

Note Appendix E of this manual will have the complete listing of software commands and categories for the factory

default of the ESTeem.

CHAPTER 1

STARTING OUT

Saving A Program

A program is saved by typing in the SAVE command at the CMD: prompt. The programming variables that have been changed
will be written to the non-volatile memory. The programming parameters will be loaded each time the modem is powered up or
reset.

Restoring Factory Defaults

The ESTeem has a very simple procedure to restore the program variables in the unit to the factory default setting. When the
FA<Enter> command is entered from the command mode the ESTeem will be configured from a variable table located in its
EPROM. It is a good practice to restore the ESTeem to a factory defaults before any programming of the unit.

To ensure the modem is in the COMMAND MODE set it back to the factory default by performing the following:

1. Set both switches (#1&2) on the RS-232 setup switches to the OFF position.

2. Reset the ESTeem.

3. Verify the computer's Comm port is configured for 19,200,N,8,1.

4. Type FA<Enter> and the ESTeem welcome message should be displayed. The characters may not be echoed on the screen.

5. Type SA<Enter> to save the factory default table.

Revised: 15 Oct 03 1-5 EST P/N AA104

CHAPTER 2

MODES OF OPERATION

The ESTeem has three major modes of operation, Command, Converse, and Transparent. This chapter of the manual describes
each one of these modes.

COMMAND MODE

The COMMAND Mode (CMD: prompt) is the default mode that the ESTeem initially enters on power -up or after a hardware or
software reset. From this mode the user can command or program the ESTeem. In this mode the user may access the various
program commands to configure the ESTeem for the specific application. These values can be stored in nonvolatile memory
within the ESTeem by the use of the SAVE command. The ESTeem reads these setup parameters stored in memory on power-up
or RESET.

When programming in the COMMAND Mode, the user need only enter enough characters to uniquely identify the respective
command.

Example: CMD:ADD 15 <Enter>

This enters the source address of the ESTeem to the decimal value of 15. The first three letters ADD were enough for the
ESTeem to uniquely identify the command for ADDress. The number of characters that need to be typed varies depending
upon the command being entered. In some cases, four or even more letters may have to be entered in order for the identification
to be uniquely determined. Up to ten multiple commands can be written on the same line if separated by a colon.

Example: CMD:ADD 15:SETC 2:SAVE <Enter>

CONVERSE MODE

This mode allows bi -directional communication from the input/output device attached to the ESTeem to a destination ESTeem
and its respective input/output device. The ESTeem will automatically switch to the CONVERSE Mode after the initial
CONNECT has been made.

When the ESTeem is in the CONVERSE Mode the * prompt will be displayed. The ESTeem will remain in the CONVERSE Mode
until the radio link has been broken or by typing a control character defined by the user with the COMMAND variable.

The factory default for the COMMAND variable is CTRL C. You can return to the CONVERSE Mode from the COMMAND
Mode by typing CONV <Enter>.

When you are in the CONVERSE Mode the echoing of the character comes from the ESTeem if ECHO = ON (factory default) has
been programmed in the ESTeem.

Transmitting Data

The ESTeem will transmit data from the CONVERSE Mode if one or more of the following conditions have been met.

1. The ESTeem transmit buffer has been filled. The size of the transmit buffer is defined in the ESTeem by the PACKLEN
variable. This variable is programmable from 1 to 2000 bytes. Factory default is 2000.

2. The ESTeem receives a SENDPAC (send packet) character from the RS-232C input data stream. The SENDPAC variable can
be defined from 0 to 255 by the user. Factory default is 13 (carriage return). The SENDPAC character is also transmitted by
the ESTeem. In file dump applications the SENDPAC character can be programmed to be the EOF (end of file) character
transmitted from the sending device (i.e.; CTRL Z, CTRL G, etc.).

Revised: 15 Oct 03 2-1 EST P/N AA104

CHAPTER 2

MODES OF OPERATION

3. Termination control timer. The termination control timer is enabled by the TERMC (on/off) command. When enabled, the
termination timer starts from the time the last transmit buffer has been updated in the RS-232C port. If the termination timer
expires before another character is received or transmitted, the contents of the ESTeem transmit buffer will be transmitted.
The waiting time of the timer is defined by the TERMT variable (termination time). The programming range of the TERMT
variable is 10-65,535ms. Factory default values are TERMC = OFF and TERMT = 50. It is noted that when the termination
timer is used, the SENDPAC variable is usually programmed to be a character that is non occurring in your data stream (i.e.;
SENDPAC = 255) so that premature transmission does not occur.

TRANSPARENT MODE

The TRANSPARENT Mode allows the ESTeem to pass all data characters (O-255 or 0-FF hex) using 8 data bits.

To program the ESTeem in the TRANSPARENT mode the TRANSPARent command must be enabled and switch Bit 2 to ON
(RS-232C Setup Switch). The TRANSPARent command will defeat the SENDPAC and COMMAND variables and put the
ESTeem in the transparent mode when Bit 2 is ON.

The transmission of the data packets can only be accomplished by enabling the termination control commands (TERMC and
TERMT) or the PACKLEN buffer being filled. The value of TERMT should be slightly longer than the maximum delay
encountered during RS-232C transmission. If this time is set to short, the ESTeem will truncate your data stream improperly.

When using the TRANSPARENT Mode, data flow control is by hardware handshaking only. Hardware handshaking is initiated
by enabling hardware flow control (XHF = ON).

The SETCON (Set Connect command) must be used to define the node that you want to communicate with while in the
TRANSPARENT Mode. When the TRANSPARENT Mode is enabled you can not communicate to the ESTeem in the
COMMAND Mode unless you use the Hardware Mode Control line (see explanation this chapter).

To remove the ESTeem from the TRANSPARENT Mode the user must perform the following:

1. Switch Bit 2, Off on the RS-232C Setup Switch.

2. Reset the ESTeem from the front panel switch.

3. Type TRANS OFF <Enter>.

Revised: 15 Oct 03 2-2 EST P/N AA104

CHAPTER 2

MODES OF OPERATION

SEMI-TRANSPARENT MODE

This mode should be utilized when sending a non-ASCII file and there is a possibility that the SENDPAC character could be
contained in the transmitted data set. Perform the following prior to programming the ESTeem to initialize the unit to factory
default settings:

1. Turn Bit 2, OFF on the RS-232C Setup Switch.

2. Reset the ESTeem.

3. TYPE FA <Enter>. Please note the characters may or may not be echoed by the CRT.

ESTeem

-------------------------

ADD xxx xxx = your address
SETC yyy yyy = destination address
TERMC ON
TERMT 10
SENDP 255
EDIT OFF
XSF ON
SAVE

If EDIT is off, and SENDPAC = 255, the SENDPAC character is disabled. This character when received will not cause packet
transmission and will be passed as normal data. The TERMC and TERMT commands are used to transmit the contents of the
ESTeem transmit buffer.

Software flow control in this example is enabled (factory default XSF = OFF) therefore the ESTeem will pass all characters except
the data flow control characters for Xon/Xoff.

HARDWARE MODE CONTROL

The MODECON (Mode Control) command is provided in the ESTeem to change the mode of the ESTeem modem from
COMMAND Mode to CONVERSE (or TRANSPARENT Mode) via a hardware control line. The hardware line is located on pin
19 of the RS-232C connector. If MODEC = ON, a "low or 0" on pin 19 (-3 to -15 vdc) will put the ESTeem in the COMMAND
Mode and a "high or one" on pin 19 ( +3 to +15 vdc) will put the ESTeem in the CONVERSE or TRANSPARENT Mode. The
factory default is OFF.

CHAPTER 3

PROGRAMMING

ESTEEM FEATURES

Listed in this chapter are the major ESTeem features and programming examples on how to use them. These features are
individual building blocks to solve your application needs. Remember your particular application may require one or more of
these features enabled.

DIGI-REPEATING

The Repeater feature allows an ESTeem to relay its respective transmission or packet through a maximum of three ESTeems to
increase the operating range of the unit. Any ESTeem in your radio network can function as a repeater for any other ESTeem.
This is independent of the fact that the ESTeem being used as a repeater is linked or connected to another node, therefore an
ESTeem can function as a repeater, operational node, or both at the same time. The data that is digi -repeated through ESTeem
will not output through the repeating ESTeem’s RS-232C port.

To specify one or more ESTeems as repeaters, the CONNECT command has been expanded to except up to three added
addresses as follows:

CONN r1,r2,r3,da

r1 = Address (1 to 254) of first ESTeem repeater.
r2 = Address (1 to 254) of second ESTeem repeater.
r3 = Address (1 to 254) of third ESTeem repeater.
Da = Address (1 to 255) of destination ESTeem.

Note: Address 255 is used for Global.

When transmitting packets through other ESTeems, the source ESTeem will automatically adjust it's FRACK time to allow
additional time for the packet to reach its destination and for the returned acknowledgment. Frack time takes into account the
packet size and the number of repeaters specified. The ACK still comes from the destination ESTeem, not the first or any
repeater.

For testing purposes, you can loop back a connection to yourself by placing your source address in the destination address of
the repeater string. Any data transmitted will repeat through the repeater address and display back on the screen.

Example:

CONN r1,Sa

r1 = Address (1 to 254) of first ESTeem repeater.
Sa = Address of local ESTeem.

Any ESTeem command in this manual that uses an address string can be configured to use the Digi-repeating feature.

Example:

SETC r1,r2,r3,da

CHAPTER 3

PROGRAMMING

ESTEEM FEATURES

GLOBAL BROADCAST

Global broadcast is the ability of one ESTeem to transmit it's message to more than one ESTeem at one time. All ESTeems within
radio range will receive the message whether or not they are connected to another ESTeem or in command or converse mode.
You can put your ESTeem in Global by connecting or programming the SETC to address 255. Address 255 is a non-assignable
unit address and is used by the ESTeem CPU to access this special mode. When the ESTeem is in Global, the standard ACK
protocol from the receiving ESTeem is disabled, but the 32 bit CRC error checking on the received ESTeem is still operational.
When you perform CONN 255 <Enter> from the COMMAND MODE the ESTeem will immediately go to the CONVERSE MODE
(* is displayed). All messages sent will be transmitted globally to all ESTeems in radio range.

In the ESTeem you have a GLOBAL (on/off) command. When GLOBAL = On, you can receive Global transmissions. If
GLOBAL = Off you will not display Global transmissions from other ESTeems.

Note: Factory default is ON.

By using the repeater function you can transmit Global messages from another ESTeem using the Digi-repeating feature.

Example:

CONN 10,20,30,255<Enter>
SETC 10,20,30,255<Enter>
By adjusting these commands you can route from unit 10 to 20, 20 to 30, and go Global at unit 30.

You can enable global transmissions in one or more ESTeem’s in your network. This will allow global communications between
all ESTeems within radio range.

AUTO TRANSMIT

The Auto Transmit feature of the ESTeem allows the user to transmit a data packet without filling up the PACKLEN (packet
length) buffer or defining a special control character using the SENDPAC (send packet) variable. The Auto Transmit feature is a
timer that is enabled in the ESTeem that monitors traffic in and out of the RS-232C port. If there are characters in the RS-232C
buffer, the termination control timer starts from the time the last receive or transmitted character is updated in the buffer. If the
termination time expires before another character is received or transmitted, the received characters are transmitted.

To enable this feature perform the following from the COMMAND MODE:

TERMC (on/off) = On. Enable termination control.

TERMT (10-65535) = One unit number equals 1ms.

TERMC is the termination control command. TERMT is the termination time command. Factory default for TERMC = Off and
TERMT = 50.

PROGRAMMING

ESTEEM FEATURES

AUTO CONNECT

The Auto Connect feature allows the user to program the ESTeem to perform a CONNECT to another ESTeem when data is sent
to the RS-232C communications port.

To enable this feature perform the following from the COMMAND MODE:

SETCON (1-255) = Address of destination ESTeem.

Remember, you can use the Repeater routing (r1,r2,r3,da) or put the ESTeem in Global (address 255). SETCON is the set connect
command.

SA SAVE command. This will save the SETC variable to the non-volatile memory so that it will not be lost when the

ESTeem is RESET.

Bit 2 (on/off) = On. Bit 2 is located on the RS-232C SETUP SWITCH on the front of the ESTeem. The ESTeem must be

RESET after the Bit has been changed to be read by the ESTeem CPU.

RESET ESTeem RESET is located on the front panel OFF/ON switch. The T/E light on the front panel of the ESTeem should

now flash at a two times per second rate.

PROGRAMMING

ESTEEM FEATURES

MULTI-CONNECT

The actual polling of the ESTeem must originate from the host device connected to the ESTeem using the CONNECT command
to originate the initial connect and the COMMAND character to return from the CONVERSE mode to the COMMAND mode.
The first time around the pole a CONNECT data packet (RF transmission) will be initiated. When a link is established, it is held
internally in the ESTeem connect table. The next time around the pole to the same address, the link status will be checked in the
ESTeem table. If the address indicates a link has already been established, then only data and its corresponding ACK will be
transmitted to that node. This greatly increases polling time by eliminating the usual CONNECT/DISCONNECT sequence each
time except when communication is first established.

The MULTID command allows the user to send data to a specific ESTeem address from the CONVERSE Mode by specifying the
ESTeem address routing before the data packet. This feature will also display the address of the sending ESTeem on any
received data.

Example Of Transmitted Data:

[001]DATA Routes data to an ESTeem addressed 1.

[100,200,250,1]DATA Routes data to an ESTeem addressed 1 via ESTeems addressed 100, 200, and 250.

The above example replaces the CONNECT command from the COMMAND Mode.
Received data packets will have the address of the ESTeem that sent the data at the beginning of the data packet.

Example Of Received Data:

[004]RECEIVED DATA Data received from ESTeem addressed 4.

[030,100,244,004] Data received from ESTeem addressed 4 via ESTeems addressed 30, 100, and 244.

MULTID (on/off) = On Enables this feature. Factory default = OFF.

REMOTE PROGRAMMING

The Remote Programming feature allows the user to remotely program ESTeems in his network. When a connection has been
made with the remote ESTeem the RPG: prompt will be displayed showing that you are now in the COMMAND mode of that
remote ESTeem.

To enable this feature perform the following from the COMMAND MODE:

PROG (1-254) Address of destination ESTeem.

Note: You can also use the Repeater routing (r1,r2,r3,da) to reach the destination ESTeem. (r1 = address of first repeater,

r2 = address of second repeater, etc. da = destination address).

To end a remote programming session, hold Control and type C (^C) and you will return to the COMMAND prompt of your
ESTeem. There is a Watch Dog Timer that will automatically disconnect you from remote programming if there is no activity for
thirty seconds.

The REMPROG (on/off) feature is used to defeat the ability of your ESTeem from being remotely programmed. If REMPROG =
OFF another ESTeem cannot remotely program your unit. Factory default = ON.

SECURITY

The Security feature allows the user to lock out programming of the ESTeem. REMEMBER TO STORE YOUR CODE NUMBER
IN A SAFE PLACE.
To enable this feature perform the following from the COMMAND MODE:

SECURITY (1 to 100,000) Entering a security number enables the security feature.

SAVE To enter the security code permanently into the ESTeem memory.

Note: When enabled, the ESTeem will output a “Security On” message.

To disable the security feature perform the following from the COMMAND mode.

CHAPTER 5

RS-232C/422/485 INTERFACING

DTE vs. DCE

The ESTeem is configured as a Data Communication Equipment (DCE) device. The following signals are available at the
RS-232C connector located at the rear of the unit.

Pin Description

---------------------------------------------------------------------

1 FG Shield Ground
2 TXD Transmit Data (Input)
3 RXD Receive Data (Output)

DCE 4 RTS Request To Send (Input)

5 CTS Clear to Send (Output)
7 SG Signal Ground

8 DCD Data Carrier Detect (Output)
12 RTS Request To Send (Output)
20 DTR Data Terminal Ready (Input)
22 Ring Ring Indicator (Output)

The important thing to remember is that for the ESTeem to communicate with an external device, the data output from pin 3 of
the ESTeem RS-232C connector must be connected to the data input of the device you are connected to; otherwise, the ESTeem
won't work. Likewise, the data input to pin 2 of the ESTeem must be connected to the data output of the device you are
connected to. Normally, if the equipment you are connecting to looks like a terminal or computer (DTE), its input, Receive Data
(RXD), will be on pin 3 its output, Transmit Data (TXD), will be on pin 2. Therefore, the ESTeem can be connected directly.

If the device you are connecting to is configured as a modem (DCE), its output will be on pin 3. If this configuration is
connected to the ESTeem, damage may result to the ESTeem or the connecting device. In this case, you can purchase a null
connector that internally reverses pins 2 and 3.

Whatever your situation may be, it is always best to check the manual on your particular device and connect accordingly.

Purchase or fabricate a RS-232C shielded cable for your ESTeem. The ESTeem requires a standard male 25 pin D connector on
one end of the cable for proper connection.

Remember to install the small retaining screws on either side of the cable connector. Tightening these screws keeps you from
accidentally losing connection with your ESTeem.

Notes:

• The ESTeem requires a shielded RS-232 cable. This is to prevent unwanted electrical noise from entering the ESTeem

and also to prevent any electrical noise from getting out of the ESTeem.

• Remember -- always use a shielded RS-232C cable.

• Pins 9, 10, 14, & 16 are used for RS-422/485 interfacing and should be left open if not used.

Revised: 8 Oct 03 5-1 EST P/N AA104

CHAPTER 5

RS-232C/422/485 INTERFACING

FLOW CONTROL

The ESTeem can be enabled to support SOFTWARE or HARDWARE flow control.

Software Flow Control

Software flow control is enabled by the XSFLOW (on/off) command in the ESTeem. When XSFLOW is ON the ESTeem will
respond to <XOFF>, (stop) and <XON>, (off) commands from the RS-232 port. The factory default setting is OFF. The default
value for START is 17 (CTRL Q) and for STOP is 19 (CTRL S).

Hardware Flow Control

Hardware flow control is enabled by the XHFLOW (on/off) command in the ESTeem. The factory default value is OFF.

When XHFLOW is enabled (on) the control signal lines, Request To Send (RTS, pin 4), Data Carrier Detect (DCD, pin 8), and
Clear To Send (CTS, pin 5) are available to the user at the RS-232C connector. The CTS and RTS signals are used to control the
flow of data into and out of the ESTeem.

The CTS signal on pin 5 is used to control the data into the ESTeem. When CTS is set (high on pin 5) the modem is ready to
receive data. When CTS is reset (low on pin 5) the ESTeem is not ready to receive data.

The RTS signal is used to control data out of the ESTeem. RTS is set (high on pin 4), by the user to indicate to the ESTeem that
the user is ready to receive data. When reset, the use r is not ready to receive data. (NOTE: Low = On, High = Off).

Revised: 8 Oct 03 5-2 EST P/N AA104

CHAPTER 5

RS-232C/422/485 INTERFACING

MEMORY BUFFERS

The ESTeem has a 4000 byte buffer on the TRANSMIT SIDE (outgoing data) and a 4000 byte buffer on the RECEIVE SIDE
(incoming data).

Transmit Buffer

The outgoing data buffer will hold two data blocks before the ESTeem will enable its RS-232C hardware/software flow control on
data coming into the modem if the network is busy. A data block in this example is a block of data that is defined by the
PACKLENGTH or SENDPAC character which ever occurs first.

Therefore, if PACKLENGTH = 10 the modem will input a maximum of 20 bytes before it enables its hardware/software handshake
line (two 10 byte packets). In another example, if PACKLENGTH = 2000 but the data block is terminated by the SENDPAC
character before the input buffer reaches the full 2000 bytes, the buffer will still hold only two data blocks if the network is busy.

In order to utilize the 2000 bytes storage for small data packets (bar code readers, etc.), program the modem using the following
guidelines:

PACKLENGTH = 2000 SENDPAC = 255
TERMC = ON TERMT = 10

Note: Set the TERMT time greater than the pause between data bursts.

By programming the above parameters the ESTeem will buffer the incoming data packets and automatically transmit the data
when the 2000 byte buffer is filled or the TERMT time limit is met. This will allow the customer to use two blocks of 2000 or 4000
bytes before the modem enables the respect hardware/software control.

Receive Buffer

If the device that the receiving ESTeem is outputting data to, enables its respective hardware or software control, the modem will
store 4000 bytes of data before flow controlling off the transmitting ESTeem.

DATA TERMINAL READY (DTR)

A software switch, DTR_ENAB (ON/OFF) is provided in the ESTeem for monitoring the status of a device connected to pin 20
of the RS-232C connector. The factory default setting is OFF. When this command is enabled the ESTeem will monitor the DTR
signal on pin 20. If the DTR line being supplied to the ESTeem, from the user, is at a SPACE (high) condition then the ESTeem is
enabled. If the DTR line is at a MARK (low) condition then the ESTeem is disabled.
This signal is normally used by the ESTeem modem as an indication that connection is made to a device that is on line and ready
to transmit/receive data.

CHAPTER 6

ANTENNA SETUPS

EST offers different types of antennas ranging from ¼ wave to 5/8 wave in physical size. The user choice is dependent on the
application.

Communications in the VHF and UHF bands are normally over "Line of Sight (LOS)". Looking from the antenna of one wireless
modem you must be able to see the antenna of the wireless modem you wish to communicate with. If a large object obstructs the
line of sight view it is unlikely that satisfactory communications will result. This means you must relocate the antennas or use the
REPEATER FEATURE and a second modem to go over or around the object.

The Model 192C, CHP, F, M and MHP products are allowed by the FCC to use high gain directional antennas.

It is noted that a ¼ wave antenna that does not have ground plane radials requires a ground plane to operate at maximum
efficiency. This can simply be a conducting surface under the antenna that is a ¼ wavelength in diameter. For the Model 192C
(450-470 MHz) this is approximately 6.5 inches. A conducting surface can be anything from the rooftop of an automobile to a file
cabinet.

COAXIAL CABLES

To minimize signal loss, the overall length of the coaxial cable should be as short as possible. To avoid corrosion select coaxial
cable manufacturers with tinned copper braid, where possible. Listed below are representative cable losses in db/100ft at the VHF
and UHF frequencies:

Frequency

(MHz)

150-174 -5.2 -4.4 -1.7 -0.964 -0.88

402-420 -8.4 -7.8 -2.9 -1.72 -1.36

450-470 -9 -7.8 -3 -1.72 -1.45

In a severe noise environment it may be desirable to use a double shield type of coax cable such as RG-214/U.

Note: Pre-made coax cables can be purchased from the factory. A -3 dB loss means you have lost 1/2 of your signal. A +3 dB

gain means you have doubled (x2) your signal.

Keep the antenna feedline as short as possible to minimize losses.

Extreme care must be taken when attaching coax connectors to the antenna feedlines. If there is any error in making

this connection the output of the transmitter will be greatly reduced.

WEATHER PROOFING COAX CONNECTIONS

1. Coat the threads of the connectors with silicone lubricant prior to assembly (See Note 1) and hand tighten. Care should be
taken not to get any lubricant on the center conductor.

2. Wrap the connector assembly with a non-adhesive silicone tape, EST part number AA243, for weather proofing (See Note 2).
Ensuring to overlap onto the coax cable approximately 1 1/2 inches and follow the instructions on the ESTeem AA243
technical bulletin.

3. Apply an electrical coating (sealing agent) over the vapor barrier patch for added protection (See Note 3).

Notes:

1. Dow Corning RTV-3140 or equivalent.

2. CoaxWrap, CW10B or equivalent.

3. SCOTCHKOTE, 3-M Company, or equivalent.

GROUNDING

All building mount antennas require attachment to a good earth ground for optimum efficiency. Contact a reputable local
communications shop for procedures for your area.

LIGHTNING ARRESTORS

Lightning arrestors should be used on all external building mount antennas for personal protection and to minimize damage to the
transceiver during lightning storms. The units should be installed as per manufacturers instructions provided with the device.

REFERENCE MATERIAL

The ideal reference book for antennas and transmission lines is the “The Radio Amateur's Handbook”, by the Headquarters Staff of
the American Radio Relay League.

CHAPTER 7

THEORY OF OPERATION

INTRODUCTION

ESTeem wireless modem products provide a "Wireless Solution" by eliminating conventional hardwiring of leased phone lines.

All of the ESTeem models come with the industry standard RS-232C, RS-422, and RS-485 asynchronous communications ports
to give the user a new dimension to "Local Area Networking".

Our packet burst, frequency agile communications products allow the user to create a "Radio Area Network" of up to 255 users
on a single frequency. The packet burst communications technique was chosen to give the system very high data integrity in
high noise industrial environments. The ESTeem incorporates a method of error checking that provides received data accuracy
of greater than one part in 100 million.

Internal Digi -Repeater features allow the user to increase operating range by relaying transmission through a maximum of three
ESTeems to reach the destination ESTeem. An ESTeem can operate as an operating node, a repeater node, or both
simultaneously for added flexibility.

"Private Data Communications" is provided by the use of an interleaving technique of the modulated data, user definable
commands for unit addressing, network addressing, and security lock-out of software programming. If higher security is
required, the ESTeem is compatible with asynchronous Data Encryption Standard (DES) encryption devices.

The ESTeem has programmable software commands to allow the user to easily configure the unit for any application or mission.
The ESTeem setup parameters are saved in non-volatile memory.

When you buy ESTeem products you are getting equipment designed by the company that holds the United States and
Canadian patent for the wireless modem. We are proud to say that we design, develop and manufacture our products in the
United States. Each ESTeem is subjected to a rigorous quality control bench test before shipping to insure our customers have
out-of-the-package reliability. We also have a dedicated Customer Support Staff, Field Engineering Services and Factory
Training classes to make sure that your application problems are solved.

HOW IT WORKS

Now, as you can probably guess, the ESTeem is a sophisticated piece of technology, however the concept is easy to
comprehend if you understand packet radio.

All packet systems, whether hardwired or radio, share the same principle of operation; data is taken from your standard RS-232C,
RS-422, or RS-485 asynchronous port and is transmitted in "Blocks". Think of this block as an "Electronic Envelope" that we
call a packet. The size of the packet can be defined by the user from 1 to 2000 bytes of information. Reducing the size of the
packet allows the ESTeem to operate better in high EMF noise environments, because by reducing the packet size you reduce
transmission exposure time on the radio waves thereby increasing your probability of a successful transmission.

Once this packet of data is formed, it’s transmitted in a "burst," one ESTeem to another, hence the term "packet burst
communications". Now, if more than one packet is required to send the data then the ESTeem goes into full automatic mode and
transmits additional packets.

Before an ESTeem transmits its packet it listens to ensure that the air waves are clear before transmitting. This listen before
transmit scheme is called "carrier sensed multiple access," or CSMA.

When a "packet" has been transmitted, every modem in radio range on the same frequency hears it. To design a modem to
communicate with a network of modems it has to be "address specific" so only the modem you want to talk to accepts your
information. It's like yelling into a crowd of 255 people but you want only the person’s name you called to acknowledge (ACK).

CHAPTER 7

THEORY OF OPERATION

Well, very simply, that's how the ESTeem works. Once the address you're calling receives your packet, it's checked for
accuracy.

Accuracy is probably the single most important part of any communication device. The ESTeem uses Forward Error Correction
(FEC) and a 32 bit Cyclic Redundancy Check (CRC) which is a very sophisticated method of checking the data integrity of the
packet once its been received. The CRC insures data integrity greater than one part in one hundred million. Once the CRC is
completed on the received packet, the data is outputted to the user and a positive acknowledgment (ACK) is transmitted back to
the sender.

It's safe to assume that the data you receive is good data or you get nothing at all using the CRC technique. If no ACK is
returned after a given delay, the sender assumes the packet was not received and "retries" the transmission. The number of
retries are user definable from 1 to 255, allowing the unit to automatically retry sending the packet.

SPECTRUM UTILIZATION

The ESTeem uses a "listen before transmit" or Carrier Sensed Multiple Access (CSMA) scheme. This means only one unit in a
network is allowed to transmit at a time. By fixing each user's communication window and allowing the computer in the ESTeem
to be the Air Traffic Controller, many individual users can share one frequency. The ESTeem firmware can support up to 255
ESTeems on a single channel or frequency. For example in the United States there are 1600 frequencies (12.5 kHz channel
spacing) in UHF, giving a network density of greater than 408,000 users in a given cell or geographical area. Once you are out of
radio range, you can construct another cell of users.

The CSMA technique is a very efficient way to manage your network of ESTeems and prevent communication bottlenecks. In
addition, an anti -collision software scheme is used to recover data if two or more units transmit at exactly the same time. When
this feature is added the technical term for this technique is now called CSMA-CD (collision detection).

By using this communications technique only one frequency channel is needed with a very narrow bandwidth (this is called
narrow band FM modulation) thereby saving valuable radio spectrum space.

PACKET PROTOCOLS

By using CSMA no polling station or token is required in the ESTeem network. When an ESTeem has information to send it will
check to see if the channel is clear before transmitting its packet and await an (ACK). The ESTeem is a Master/Master system,
meaning any ESTeem can communicate with any other ESTeem.

FLOW CONTROL

The ESTeem supports hardware and software flow control, which allow different devices on the network to communicate at
different baud rates. In addition to flow control the ESTeem also has a 4000 byte data buffer on both the receive and transmit
buffers in the unit.

DATA PRIVACY

Data privacy in the ESTeem is provided by three levels of data encoding in the firmware and by the user being able to define
over four security and communications parameters (Unit Address, Network ID, and Operating Frequency) that allow
communications access to the modem giving over 100 million combinations. If higher security is required, the units are
compatible with asynchronous Data Encryption Standard (DES) encryption peripherals.

CHAPTER 7

THEORY OF OPERATION

EFFECTIVE BAUD RATE

The maximum input baud rate to the modem is 19,200 baud, asynchronous, full duplex, but this is misleading since the ESTeems
actually communicate to each simplex over the RF link, at 19,200 bps (25 kHz channel spacing - Model 192C/F) or 9,600 bps (12.5
kHz channel spacing - Model 192C/F). The effective baud rate is a function of the above plus the packet length variable in the
ESTeem (definable from 1 to 2000 bytes). If the packlength variable is set to 2000 bytes the effective baud rate is approximately
18,000 baud (25 kHz channel spacing) or 9,000 baud (12.5 kHz channel spacing) the effective baud rate will degrade as the
packlength variable is reduced.

Another item that must be understood is transmission turn around time. Remember that the ESTeem sends a data packet and
waits for an (ACK) from the destination modem before another packet is transmitted. All radio transmitters have a fixed delay
time, this is the amount of time it takes the transmitter to stabilize once it is energized before it can send data. In the ESTeem the
delay is approximately 15 milliseconds one way which includes transmitter turn-on time and packet frame overhead or a total turn
around time accounting for the (ACK) of 30 milliseconds. Therefore total time to send a data packet is 30 milliseconds plus the
time required to send the data (i.e. number of bits sent/19,200 b/s).
