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.

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

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

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:
1. T u rn Bit 8 OFF on the RS-232C Setup Switch.
2. Reset the ESTeem.
3. TYPE FA <cr>. Please note the characters my not

the reference ESTeem. It is noted that repeater address
strings can be assigned to the remote ESTeem SETC
