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.
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>.
Example: ADD<cr>, will list the current address saved
in the connected ESTeem.
Figure 10: Test Radio Communication
CHAPTER 1
STARTING OUT
Revised: 27 Mar 01 1-6
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.
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 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<cr> and the ESTeem welcome message
should be displayed. The characters may not be
echoed on the screen.
5. Type SA<cr> to save the factory default table.
CHAPTER 2
MODES OF OPERATION
Revised: 27 March 01 2-2
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.).
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.
CHAPTER 2
MODES OF OPERATION
Revised: 27 March 01 2-3
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>.
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 = HARDWARE, 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
SOFTWARE.
CHAPTER 3
PROGRAMMING ESTEEM FEATURES
Revised: 27 March 01 3-2
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 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. 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 an ESTeem will not be 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
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 an 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.
CHAPTER 3
PROGRAMMING ESTEEM FEATURES
Revised: 27 March 01 3-3
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 more than one
ESTeem 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.
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.
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.
CHAPTER 3
PROGRAMMING ESTEEM FEATURES
Revised: 27 March 01 3-4
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 an
ESTeem addressed 4.
[030,100,244,004] Data received from an 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.
SECURITY (1 to 100,000) Entering your security
number disables the
security feature.
SAVE To remove the security code permanently from
the ESTeem memory.
Note: When disabled, the ESTeem will output a
“Security Off” message.
CHAPTER 3
PROGRAMMING ESTEEM FEATURES

HARDWARE RING LINE (Factory Option)
When the ESTeem establishes a CONNECT or link with
another ESTeem (T/E Light on solid), pin 22 at the
ESTeem RS-232C will change from a -15 vdc voltage
state to a +15 vdc voltage state. The RING software
command allows the user to change the output from a
latched state to a pulsed state. To change the state of this
line program the following from the COMMAND mode.
Factory default = LATCH.
RING =Latch. Pin 22 is high when the ESTeem T/E
light is on solid.
RING =Pulse. Pin 22 is pulsed (positive 250 ms.) when
the ESTeem T/E light is on solid.
PACKET MONITOR
The PACKM [ON/OFF] command places the ESTeem in
a special packet monitor mode. When this feature is
enabled the ESTeem is placed in a receive only mode and
will not function as a normal ESTeem. The ESTeem will
monitor and report the status of all message traffic within
the network in the following format, the actual packet
message will not be outputted.
SA-xxx, DA-xxx, Type Code, R1-Repeater Status, R2-

USING THE INFRARED
COMMUNICATIONS PORT
The infrared (IR) communications port will allow you to
program and interrogate the ESTeem without
disconnecting the serial cable from the back of the
modem. The IR port is located on the front panel of the
ESTeem, above the T/E light.
To communicate from a computer to the ESTeem
through the IR port you will need a copy of the ESTeem
Utilities (Version 4.0 or higher) and an ESTeem IR
Communication Dongle (ESTeem P/N AA300).
Connect the dongle directly to the serial port of the
computer. The dongle requires initialization from the
ESTeem Utilities. From the Terminal Emulation screen
press the F3 function key to initialize the dongle. If the
modem is not in the COMMAND mode, press CTRL-C
to display the CMD: prompt.
Note:With Switch 2 (RS-232 Setup) in the On position
the ESTeem defaults the IR port to the command
mode.

CHAPTER 5
RS-232C/422/485 INTERFACING
Revised: 27 Mar 01 5-2
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.
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 user is not ready to receive data.
(NOTE: Low = On, High = Off).
CHAPTER 5
RS-232C/422/485 INTERFACING
Revised: 27 Mar 01 5-3
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.
RS-422/485 CONFIGURATION
The ESTeem will support the requirements of the EIA
Standard RS-422/485. This is a four (4) wire interface
consisting of the TRANSMIT DATA (-), TRANSMIT
DATA (+), RECEIVE DATA (-), AND RECEIVE
DATA (+) or a two (2) wire interface using B (+) and A
(-). These signals are available at the 25 pin RS-232C
connector on the modem.
Pin Description
9 BTR (-) TRANSMIT DATA (-)
10 BTR (+) TRANSMIT DATA (+)
DCE 14 BRX (+) RECEIVE DATA (+)
(4-Wire) 16 BRX (-) RECEIVE DATA (-)
Pin Description
DCE 14 (+) HALF-DUPLEX B (+)
(2-Wire) 16 (-) HALF-DUPLEX A (-)
This interface is designed to provide unipolar differential
drive to twisted pair or parallel wire transmission lines.
Note: The ESTeem is configured at the factory for
RS-422 interfacing . RS-485 (either 4 or 2 wire
mode) requires internal jumper configuration.
Please contact EST Customer Support at 509-
735-9092 for instruction.
The ESTeem can be factory configured RS-485
interfacing prior to shipment. Call EST

CHAPTER 6
ANTENNAS
Revised: 27 Mar 01 6-2
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 "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/F/M 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 192C this is approximately 6.5
inches. A conducting surface can be anything from the
roof top 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) RG-58u RG-8 ½” Heliax
---------------------------------------------------------------------
150-174 - 5.2 - 2.3 - 0.845
402-420 -10.0 - 4.2 - 1.5
450-470 -10.8 - 4.4 - 1.5
In a severe noise environment it my 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 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).

Revised: 27 Mar 01 6-3
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.

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.

THEORY OF OPERATION
Revised: 27 March 01 7-2
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). 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.
CHAPTER 7
THEORY OF OPERATION
Revised: 27 March 01 7-3
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.
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).
