HELP Functions
The ESTeem has over a hundred 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.
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<cr> 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 to
set it back to the factory default perform the following:
1. Set Bit 8 on the RS-232 setup switches to the OFF
position.
2. Reset the ESTeem.
3. Type FA<cr> and the ESTeem welcome message
should be displayed. The characters may not be
echoed on the screen.
4. Type SA<cr> to save the factory default table.
You can interrogate a discrete software command by just
typing the command followed by a <cr>.
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.
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.

CHA PTER 2
MODES OF OPERA TION
The ESTeem has three major modes of operation,
Command, Converse, and Transparent. This chapter of
the man u al describes ea ch one of these modes.
COMMAND M ODE
The COMMAND Mode (CMD: p rompt) 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 E ST eem 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:
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. Th e number of characters t hat
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 commands can be
written on the same line if separated by a colon.
Example:
CMD:ADD 15 <cr>
CMD:ADD 15:SE T C 2 : SAVE < cr>
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 t he initial CONNEC T has been
made.
When the ESTeem i s i n 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 t he COMMAND vari a ble.
The factor y default for t he COMMAND vari a ble i s
CTRL C. You can retur n to the CONVE RSE Mode fr om
the COMMAND Mode by typing CONV <cr>.
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 1010 bytes. Factory default
is 1010.
2. Th e ESTeem receives a SENDPAC ( send pa ck et )
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 i s also tra nsmitted 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
(ie; CTRL Z, CTRL G, etc.).
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 an ot her character is received or tra nsmitted,
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 1-255
(one unit equals 16.67 ms.). Factory default values
are TE RMC = OFF a nd TERMT = 1 0 . I t i s noted
that when the termination timer is used, the
SENDPAC vari a ble i s u su ally programmed to be a
character that is non occurring in your data stream
(ie; SENDPAC = 255) so tha t premature
transmission is not caused.
2-2
CHA PTER 2
MODES OF OPERA TION
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 th e E ST eem i n th e T RANSPARENT m ode
the SET MODE ( on /off) and SETTRANS (on/off)
commands must be enabled (SETMODE = ON and
SETTRANS = ON) and switch Bit 8 to ON (RS-232C
Setup Switch) . T he SETMOD command will defeat the
SENDPAC an d COMMAND variables and will put the
ESTeem in the transparent mode when Bit 8 is ON.
The SETTRANS command when enabled will program
the following discrete commands:
AUTOLF = OFF ECHO = OFF EDIT = OFF
PROMPT = OFF TYPS = OFF
PLEASE NOTE: When SETTRANS is enabled th e
screen will go blank because ECHO has been disabled,
therefore this should be the last variable programmed
before the SAVE command.
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 usi ng th e T RANSPARENT Mode, d ata flow
control is by hardware handshaking only. Hardware
handshaking is initiated by enabling hardware flow
control (XHF = ON) or the Request to Send/Clear to
Send lines (RTS_CTS = ON) and disabling software flow
control (XSF = OFF) in the ESTeem.
The SETCON (Set Connect) or ALTERO (Alternate
Route) commands must be used to define the node that
you want to communicate with because while in the
TRANSPARENT Mode you can not commun icate to th e
ESTeem in the COMMAND Mode unless you use the
Hardware Mode Control line (see explanation this
chapter).
To remove the EST eem from the TRANSPARENT Mode
the user must perform the following:
1. Switch Bit 8, Off on the RS-232C Setup Switch.
2. Reset the ESTeem from the front panel switch.
3. Type FA <cr>. The characters FA will not be
echoed on your CRT because the ECHO command in
the ESTeem is disabled.
HARDWARE MODE CONTROL
The MODECON ( Mode Con t rol) command is provided
in the ESTeem to change the mode of the ESTeem
modem from COMMAND Mode to CONVERSE or
TRANSPARENT Mode via a hardwar e cont rol line. Th e
hardware line is located on pin 19 of the RS-232C
connector. If MODEC = HARDWARE, a "low or 0" on
pin 19 (-3 to -15 vdc) will put the ESTeem in the
COMMAND Mode and a "high or on e" on pin 19 ( 3 to
15 vdc) will put the ESTeem in the CONVERSE or
TRANSPARENT Mode. Th e factor y default is
SOFTWARE.
Pin 6 on the ESTeem RS-232C connector provides a
feedback status to the user when MODECON is set to
HARDWARE. A "high or 1" condition on pin 6
indi ca t es t he ESTeem modem i s in the COMMAND
mode. A "low or 0" condition on pin 6 indicates the
ESTeem modem i s i n the CONVERSE or
TRANSPARENT mode.
CONDITIONAL TRANSPARENT MODE
This mode is a special version of the TRANSPARENT
Mode. This mode is entered by typing the following from
the COMMAND Mode:
TRANS X <cr>
The " X " specifies t he number of packets t o be sent before
returning to th e COMMAND Mode. I f the argu m ent is
set to zero or not entered, then the original form of the
Transparent Mode will be executed. When using this
command the ">" prompt will be displayed on your CRT.
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.
2-3
CHA PTER 2
MODES OF OPERA TION
Perform the following prior to programming the ESTeem
to initialize the unit to factory default settings:
1. T u rn Bit 8, OFF on t he RS-232C Setup Switch.
2. Reset the ESTeem.
3. TYPE FA <cr>. Please note the characters may or
may not be echoed by the CRT.

HAYES MODE EMULATION
The ESTeem modem is placed in the Hayes Emulation
Mode by setting the HAYES (on/off) software command
to ON.
When the HAYES command is enabled (HAYES = 0N)
the ESTeem will respond to certain Hayes modem
commands from the RS-232C port.
The HAYESTIM (x) command (Hayes protocol
termination sequence delay) is used to define the delay
which terminates the Hayes protocol sequence. Listed
below are standard values for "x".
11 = 4800 b/s 22 = 2400 b/s 44 = 1200 b/s

PROGRA M MING 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
my require one or more of these features enabled.
DIGI-REPEATING
The Repeater feature allows an ESTeem to relay it's
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 independent of the fact
that the ESTeem being used as a repeater is linked or
conn ected to anoth er n ode. Th erefore a n ESTeem can
function as a repeater, operational node, or both at the
same time. The data that is digi-repeated through an
ESTeem will not be output through its respective
RS-232C port.
To specify one or more ESTeems as repeaters, the
CONNECT command has been expanded to accept up to
three added addresses as follows:
CONN r1, r2,r 3 , d a
r1 = Address (0 to 253) of first repeater.
r2 = Address (0 to 253) of second repeater.
r3 = Address (0 to 253) of third repeater.
da = Address (0 to 255) of destination ESTeem.
Example:
SETC r1,r2,r3,da
GLOBAL BROADCAST
Global broadcast is the ability of one ESTeem to transmit
it's message to more than one ESTeem at once. All
ESTeems within radio range will receive the messa ge
whether or not they ar e connected to anoth er ESTeem or
in command or converse mode. The global message will
have the highest priority over all other traffic on the
receivi ng E STeem.
You can put your ESTeem in Global by connecting to
address 255. Address 255 is a non assignable unit
address and is used by the ESTeem CPU to put the
modem in this special mode. When an ESTeem is in
Global the st and a rd AC K p rotocol from the recei vi ng
ESTeem is disabled, but the 16 bit CRC error checking
on the received ESTeem is still operational.
When you perform CONN 255 <cr> from the
COMMAND MODE th e E ST eem will immediately go to
the CONVERSE MODE (* is disp l ayed). All messages
sent will be transmitted globally to all ESTeems in radio
range.
In your ESTeem you have a GLOBAL (on/off)
command. When GLOBAL = On, you will receive
Global transmissions. If GLOBAL = Off you will not
display Global transmissions from other ESTeems.
Factory default is ON.
: Address 254 is used for self test and address 255
Note
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 repeater.
For testing purposes you can answer back to yourself if
you place your source address in the destination address
of the repeater string.
REMEMBER, you can use a repeater address string in
any command that requires a specific address in this
manual.
3-2
By using the repeater function, you can go Global from
another ESTeem.
Example:
CONN 10,20,30,255 <cr>. By performing th i s conn ect
string you can route from unit 10 to 20, 20 to 30, and go
Global at unit 30.
You can also enable global in more than one ESTeem in
your network and have all units talk to all other units at
the same time.
AUTO TRA NSMIT
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 chara ct er using t he SENDPAC (sen d packet)
CHA PTER 3
PROGRA M MING ESTEEM FEATURES
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 chara cters in the RS-232C
buffer, the termination control timer starts from the time
the last receive or tra nsmitted character is updated in the
buffer. If the termination time expires before another
charact er is received or tr ansmitted, the received
characters are transmitted.
To enable this feature perform the following from the
COMMAND MODE:
TERMC (on/off) = On. Enable termination control.
TERMT (1-255) = One unit number equals 16.67 ms.
(i.e. 60 units equal 1 second).
TERMC stands for termination control. TERMT stands
for termination time. Factory default for TERMC = Off
and TERMT = 10.
AUTO CONNECT
The Auto Connect or Auto Dial Up feature allows the
user to pr ogram the ESTeem to per form a CONNECT t o
another ESTeem when data is sensed in its’ respective
RS-232C communications port.
front panel of the ESTeem should now
flash at a twice per second rate.
AUTO DISCONNECT
The Auto Disconnect feature allows the user to program
the ESTeem to automatically disconnect the radio link if
there is no data being received or transmitted through its
respective RS-232C port for the time frame defined by
IDLET (idle port timer).
To enable this feature perform the following from the
COMMAND MODE:
IDLEC (on/off) = On. Enables idle port disconnect.
IDLET (1-255) = One unit number equals one
second if IDLEF = Off. One unit
equals one millisecond if IDLEF =
On.
IDLEF (on/off) = Ch anges t he scale of IDLE T above.
IDLEF stands for idle port timer fine control.
Factory default for IDLEC = Off, IDLET = 30, and
IDLEF = Off.
To enable this feature perform the following from the
COMMAND MODE:
SETCON (0-255) = Address of destination ESTeem.
NOTE: You can use the Repeater routing (r1,r2,r3,da) to
put the ESTeem in Global (address 255). SETCON
stands for set connect.
SA SAVE command. This is to save the SETC
variable to the non volatile memory so that it
will not be lost when the ESTeem is RESET.
Bit 8 (on/off) = On . Bit 8 is located on the RS-232C
SETUP SWITCH on the rear of the
ESTeem. Remember the ESTeem must
be RESET after the Bit has been
changed to be read by the ESTeem
CPU.

AUTO CALL BACK
The Auto Call Back feature allows the ESTeem to
automatically call back a destination ESTeem if that
ESTeem is connected t o a nother node.
To enable this feature perform the following from the
COMMAND MODE:
RECONN (on/off) = On. Enables reconnect feature.
RECONR (1-255) = One unit num ber stan ds for the
number of retries that will be made
if the destination address is
connected to another node.
RECONR stand s for reconnect

CHA PTER 3
PROGRA M MING ESTEEM FEATURES
Factory default for RECONN = Off, RECONR = 10 , and
RECONT = 1.
ALTERNATE ROUTING
The Alternate Routing feature allows the user to define
up to four communication routes for the ESTeem. The
communication routes or paths are changed when the
ESTeem is unable to perform a CONNECT or t he
DESTINATION C ONNE C T ED TO ANOTHER NODE
message is encountered. The ALTERETRY variable
defines the number of connect attempts before switching
to the next route. The ESTeem will start with the route
defined in ROUTE 1 or the last route used in its table.
To enable this feature perform the following from the
COMMAND MODE:
ALTERO (on/off) = On. Alternate Routing is enabled.
When this feature is enabled the user will be prompted to
enter Route 1, Route 2, Route 3, and Route 4. If all four
routes are not needed for your application then enter a
<cr> for the last route entered.
Remember

should be defined the same as
Route 1.
The ESTeem RETRY variable determines the number of
times that you will go through the ALTERNATE
ROUTE table before a "LINK IS DOWN" message will
appear.
CALL WAITING
The Call Waiting feature will tell the addresses of the
first five ESTeems that attempted to connect to you when
you were connected to another node. If a connect attempt
has been made from another ESTeem the following
message will be displayed when you return to the
COMMAND MODE from the CONVERSE MODE.
* NODE CONNECT ATTEMPTS WERE
The NODES command will display the addresses of the
first five callers.
Example:
The ESTeem will output the addresses in the following
format:
NODES = [address 1], [ad dress 2], [a d d ress 3],
If a "*" p recedes t he add ress then one or more rep eater s
were used to reach you. To determine the repeater
routing path th e NODES PATH command must be used.
To use this command type NODES PATH(x) where x =
the number of the caller (x can be 1, 2, 3, 4, or 5).
The NODES CLE AR command is used to clear the nodes
buffer. The nodes buffer is automatically cleared when a
conn ect is made.
When you are connected to anot her node you can
momenta rily return to the COMMAND MODE to check
the n odes buffer and return back t o the CONVERSE
MODE with out breakin g your communications link.

MULTI-CONNECT
The Multi-Connect feature when enabled allows an
ESTeem to perform a direct connect to more than one
ESTeem at a time. The maximum number is 255. This
feature changes the usual ESTeem point to point protocol
to a point to multi-point protocol. The main use of this
feature is in a polled or contention applications where
3-4
CHA PTER 3
PROGRA M MING ESTEEM FEATURES
many remotes are sending data to a common point. The
stand a rd CONNECT ( t ran sm ission plu s ACK) a nd
DISCONNECT (transmission p l u s AC K) are eliminated.
This feature will also allow REPORT BY EXCEPTION
(a remote can communicate with a central point even
though it is not being polled or addressed by the central
point).
To enable this feature perform the following from the
COMMAND MODE:
MULTCON (on/off) = On.
Multi-Connect is enabled. Factory default = OFF.
The actual polling of the ESTeem must originate from
the host devi ce connected to the ESTeem by usin g the
CONNECT command (to originate the initial connect)
and t he COMMAND character , to retur n from the
CONVERSE mode to th e COMMAND m ode. T he first
time around the poll a CONNECT data packet (rf
transmission) will be initiated. When a link is
established it will be remembered internally in the
ESTeem connect table. The next time around the poll 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/DI SC ONNE C T sequ ence each time except
when the initial communication is established.
Two other software features have been added to support
the MULTI-CONNEC T command; The MULT-ID
command and the MULTDEL command.
The MULTID command allows the user to send data
from the CONVERSE Mode by specifying th e a dd ress
routing before the data packet. This feature will also
display the address of sending ESTeem on an y r ecei ved
data.
This replaces using the CONNECT command from the
COMMAND Mode. The br a cket s [ a nd ] are defined
using the MULTDELI command.
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 recei ved from an
ESTeem addressed 4.
[030,100,244,004] Data received fr om an
ESTeem addressed 4 via
ESTeems addressed 30, 100,
and 244.
MULTID (on/off) = On Enables this feature. Factory
default = OFF.
MULTDEL (0-255,0-255)Defines the delimiters used to
bracket the MULTID address
when enabled. Factory default
= 91,93.
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 (0-254) = Address of destination ESTeem.
Remember, you can also use the Repeater routing
(r1,r2,r3,da) to reach the destination ESTeem.
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.

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 EST eem
cannot remotely program your unit. Factory default =
ON.

RADIO SELF TEST
The Radio Self Test feature is used to test the radio
conductivity of a given geographical area without the use
of external hardware attached to the ESTeem
(i.e. terminal, computer, etc.) by performing a GO or NO
GO test by visually looking at the ESTeem T/E light. If
after resetting the ESTeem the T/E light changes from a
twice per second flash rate to solid ON light the radio
path has been tested. This test is usually done by
attaching a 12 VDC battery pack to the remote ESTeem
and walking a given area and pushing the reset switch to
test the radio path at various points of interest relative to
a fixed reference point. This test is used to give the user
a rough test of the radio operating range but does not
give signal strength, back ground noise levels, or sources
of co-channel int erference.
To perform a radio self test requires two
ESTeems. Address 254 is a special address used for the
self-test feature and is assigned to the remote ESTeem.
After addressing the remote ESTeem to 254 it is then
programmed to auto connect to the reference ESTeem.
Address 254 is a special command that allows the
ESTeem to per form t he AUTO CONNECT up on reset,
not when the unit senses data through it's RS-232C port.
Perform the following prior to programming the
ESTeem(s) to initialize the units to factory default
settings:

RS-232C/422/485 INTERFACING
DTE vs. DCE
The ESTeem is configured as a Data Communication
Equipment (DCE) device. The following signals
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 directly connected.
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.
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.
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 ON. 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.
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
5-2
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 user is not ready to receive data.
(NOTE: Low = On, High = Off).
CHAPTER 5
RS-232C/422/485 INTERFACING
MEMORY BUFFERS
The ESTeem has a 2020 byte buffer on the TRANSMIT
SIDE (outgoing data) and a 2020 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 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
accept a maximum of 20 bytes before it enables its
hardware/software handshake line (two 10 byte packets).
In another example, if PACKLENGTH = 1010 but the
data block is terminated by the SENDPAC character
before the input buffer reaches the full 1010 bytes, the
buffer will still hold only two data blocks if the network
is busy.
In order to utilize the 2020 bytes storage for small data
packets (bar code readers, etc.), program the modem
using the following guidelines:
PACKLENGTH = 1010 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 1010 byte buffer is filled or
the TERMT time limit is met. This will allow the
customer to use two blocks of 1010 or 2020 bytes before
the modem enables the respect hardware/software
control.
REQUEST TO SEND/CLEAR TO SEND
A software switch, RTS_CTS (on/off), is provided in the
ESTeem for operation of the Request to Send (RTS) pin 4
and Clear to Send (CTS) pin 5 when Hardware Flow
control is not necessary or available, but the RTS/CTS
lines are required. When the users device raises the RTS
line (Pin 4) the ESTeem will assert the CTS (Pin 5) in
response. This feature is used to have the ESTeem
emulate a standard phone modem, but can NOT be used
a method of flow control.
When the RTS_CTS software switch is ON,
HARDWARE FLOW CONTROL can NOT be enabled in
the ESTeem.
The factory default setting for this switch is OFF.
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.
Also note that if DTR command is enabled, and the line
is disabled then the ESTeem will perform a "Disconnect"
if connected. DTR enabled also turns on Carrier Detect
(pin 8) if the ESTeem is "Connected" to another
ESTeem, Carrier Detect will go off if the ESTeem is
"Disconnected".
Receive Buffer
If the device that the receiving ESTeem is outputting data
to, enables its respective hardware or software control,
the modem will store 2020 bytes of data before flow
controlling off the transmitting ESTeem.

EST offers different types of antennas ranging from 1/4
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
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 United States Federal Communications Commission
(FCC) specifies that th e antenna type used on the
ESTeem Model 95 be limited to one-half wave vertically
polarized omni-direction in design. This limits the
overall gain of the antenna to a maximum of
approximately 3 dB.
The Model 96 products are allowed by the FCC to use
high gain directional antennas.
It is noted that a 1/4 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 1/4 wave length in
diameter. For the Model 95 this is approximately 42
inches. A conducting su rface ca n be an ythin g from t he
roof top of an automobile to a file cabinet.

Notes:
1. Pre-made coax cables can be purchased from the
factory. A -3 dB loss means you have l ost 1/2 of
your signal. A +3 dB gain means you have double d
(x2) your signal.
2. Keep the antenna feedline as short as possible to
minimize l o sse s.
3. 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
lubricant on the center conductor.
2. Wrap the connector assembly with a vapor barrier
patch for weather proofing (See Note 2), ensuring to
overlap onto the coax cable approximately 1 1/2
inches.
3. Apply a electrical coating (sealing agent) over the
vapor barrier patch for added protection (See Note
3).

COAXIA L CABLES
To minimize signal loss, the overall length of the coaxial
cabl e s hould be as short as possi ble. To avoid corros ion
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:

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 VHF and UHF
communications products allow the user to create a
"Radio Area Network" of up to 254 users on a single
frequency. The packet burst communications using
Synchronous Data Link Control (SDLC) technique was
chosen to give the system very high data integrity in high
noise industrial environments. The ESTeem incorporates
a met hod of error checking that p rovides 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
the ESTeem firmware SDLC, bit compression, and
Man chester encoding techniqu es. Th e user ca n define
over four different security code and communications
parameter groups that allow communication access to the
"Radio Area Network". If higher security is required, the
ESTeem is compatible with asynchronous Data
Encryption Standard (DES) encryption devices.
The ESTeem has over a 100 programmable software
commands to allow the user to easily configure the unit
for any application or mission. The ESTeem setup
parameters are saved in its own 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 shippi ng to in su re 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 problem are solved.
ESTEEM HOW IT WORKS
Now, as you can probably guess, the ESTeem is a
sophi s ticat ed piece of technol ogy, however the concept is
easy to comprehend if you understand pa cket radi o.
All packet systems, whether hardwired or radio, share the
same principle of operation; data is taken from your
standard RS-232C 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 1010 bytes of
information. Reducing the size of the packet allows the
ESTeem to operate better in high EMF noise
environm ents, because by redu cing 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, its 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 in formation. It's like yelling into a
crowd of 255 people but you want only the persons name
you called to acknowledge (ACK). Well, very simply,
that's how the ESTeem works. Once the address you're
calling receives your pa ck et, it's checked for accuracy.
Accuracy is probably the single most important part of
any communication device. The ESTeem uses a 16 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 i nsures dat a
integrity greater than one part in one hundred million.
Once t he CRC is com p leted on th e received p acket, the
data is outputted to the user and a positive
acknowledgment (ACK) is transmitted back to the
sender.
7-1
CHA PTER 7
THEORY OF OPERATION
It's safe to assume that the data you receive is good d ata
or you get nothing at all using the CRC technique. If no
ACK is returned after a given delay, the sender assumes
the p acket was not received and "retries" t he
transmission. The number of retries are user definable
from 1 to 255, allowing the unit to automatically retry
sending the p a cket.
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 253
ESTeems on a single channel or frequency. For example
in the United States there are over 50 frequencies
available in the VHF spectrum and 1600 frequencies in
UHF, giving a network density of greater than 16,830
users in a given cell or geographical area. Once you are
out of radio range, you can construct another cell of
users.
The CSMA techniqu e i s a ver y 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).
FLOW CONTROL
The ESTeem supports hardware an d 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 2020 byte data buffer on
both t he receive and tra nsmit buffers in the modem.
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, Operating
Frequency, and HDLC Communications Baud Rate) that
allow communications access to the modem giving over
200 million combinations. If higher security is required,
the units are compatible with asynchronous Data
Encryption Standard (DES) encryption peripherals.
EFFECTIVE BAUD RA TE
The maximum input RS-232C baud rate to the modem is
9600 baud, asynchronous, full duplex, but this is
misleading since the ESTeems actually communicate to
each other half duplex, synchronous, at 4800 b/s. The
The effect ive baud rat e is a func tion of the a bove items
plus the packet length variable in the ESTeem (definable
from 1 to 1010 baud). If the packlength variable is set to
1010 baud the effective baud rate is approximately 4484
baud but the effective baud rate will degrade as the
packlength variable is reduced.
By using this communications technique only one
frequency channel is needed with a very narrow
bandwidth (this is called narrow bank 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.
7-2
Another item that must be understood is transmission
turn around time. Remember, 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, which 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 45 milliseconds one way which
includes transmitter turn-on time and packet frame
overhead or a total turn around time accounting for the
(ACK) of 90 milliseconds. Therefore total time to send a
data packet is 90 milliseconds plus the time required to
send the data (ie. number of bits sent/4800 b/s). There
are tables in Appendix D that give the user greater detail
on this subject.

This message is caused by either receiving a reply from a Log
On Packet, receiving a Log On Packet, or by typing LINK when
connected and in the COMMAND MO DE. XX is the address
of the modem connected to.
2. A "DISCONNECTED FROM X X"
B SSO2-xx
Tells that you have been disconnected from the device you
were originally co nnected to (xx is unit address).
3. A "DESTINATION CONNECTED TO ANOTHERNODE"
B SSO3
This message occurs while trying to log to a node that is
already logged to another node. The destination node sends a
Node Busy Packet which, when received, causes this message
to be displayed. The ESTeem remains in the COMMAND
mode.
4. A "LINK BUSY"
B SSO4
This message is caused by receiv ing a Node Busy Packet from
the destination node. Any further packet transmission is
disabled until a Node Ready Packet is received from the
destination node.
7. A "LINK DOWN"
B SSO7
This message occurs after sending the last retry data packet
and receiving no response from the destination node. This
message usually indic ates a har d failure -i.e. destination node
not energized, wrong baud rate, (not compatible between units)
improper transmit/re ceive frequency between nodes, etc.
8. A "ADDRESS USED AS SOURCE!"
B SSO8
The Connect Address you gave is the same as your Unit

This message is caused by an invalid sequence number
between transmit and receive. T his could happen if the data
somehow was modified during transmission. The normal
recovery from this message is to reconnect. This will
synchronize the sequence numbers between the transmit and
sending ESTeems. This message usually indicates a soft
failure in the link.
6. A "DESTINATION NODE RESET"
B SSO6
This message is caused by the destination node being reset
(power up, down, etc .), and the other node continues to send
data. The normal recovery from this message is to reconnect.
This will synchronize the sequence numbers between the
transmit and sending ESTeems. This message usually
indicates a soft failure in the link.

SOFTWAR E COMMANDS
TERMCont (on /off)
The RS-232 receive termination timer.
ON: If there are characters in the RS-232 buff er and the modem is
in Converse Mode, the termination timer starts from the time
the last receive character is updated in the buffer. If the
term inati on time exp ires b efore an other c harac ter is recei ved,
the characters are transmitted.
Factory default = OFF.
TERMTime (1-255)
The RS-232 receive termination timer value. T his value can be 1 to
255 tick intervals (1 tic = 16.67 ms.). This value time out is enabled
by TERMCONT.
Factory default = 1O.
TRans (0-255)
The transparent mode command. The execution of this command
causes an immediate exit by the ESTeem unit COMMAND mode to
TRANSPARENT mode and cannot be saved by the SAVE
command. This mode allows the ESTeem link to be completely
transparent to the communicating RS-232 devices. When in
transparent mode, and prompts are enabled, a ">" is dis played on
the terminal. If a variable is specified with this command the
ESTeem will return to the COMMAND Mode after the number of
transmissions equal the number specified.
EXAMPLE: CMD: TRANS <cr>
The ESTeem would immediately be placed in the T RANSPARENT
Mode (> prompt would be displayed) and remain in that mode until
the ESTeem was hardware reset.
EXAMPLE: CMD: TRANS 5 <cr>
The ESTeem would immediately be placed in the T RANSPARENT
Mode and would return to the COMMAND Mode after five
transmissions.
TXDATA (1-255)
This command defines the transmit data delay in milliseconds.
TXEnd (1-255)
TXSTAT (clear/high/low)
This command prints the total number of rf transmissions vs. the
total number of retries.
CLEAR: Initiation of this command causes the total tr ansmit and
retry count to be zeroed.
HIGH: Initiation of this c ommand displays the upper 16 bit value
of the total transmit count and the total retry count.
LOW : Initiation of this command displays the lower 16 bit value
of the total transmit count and the total retry count.
TYPerr (on /off)

RECEIVER SQUELCH SELECTION
An application may arise where environmental noise triggers the
carrier dete ct circuitry and inhibits operation of the ESTeem. The
user has the option to increase receiver squelch above the noise.
Increasing the receiver squelch allows operation of the ESTeem in
the users' high noise environment.
REMEMBER, an increase in receive r squelch causes a
corresponding decrease in range.
Receiver squelch switches are provided on the rear of the ESTeem
to allow the user to select different values of receiver sensitivity.
The last two bits (11 & 12) on the Frequency Select Switch located
on the rear panel of the ESTeem a re used to adjust the receiver
carrier dete ct threshold. Four ranges are prov ided for the user.
Listed below are the switch settings.
