BASIC ESTEEM PROGRAMMING
Most of the ESTeem commands outlined in this section have been
automatically input to the modem by the ESTeem Utility program.
A few of the commands used most often in troubleshooting and
programming are covered here. These commands can be
programmed to the modem directly by the Terminal Emulation
section of the utility or by any other terminal software package.
CHAPTER 1
STARTING OUT
HELP Functions
The ESTeem has over eighty software commands to aid the user in their application. The HELP command allow the user to list
the various software commands and their respective values.
From the COMMAND mode, type HELP<cr>. Your display should list the following:
Help switches are:
ALL (Lists all settings).
CHANGE (List settings changed from factory default).
CONTROL (List settings dealing with control).
PLC (List settings for PLCs).
RADIO (List settings for ESTeem radio).
RS232 (List settings for RS-232/422/485)
SETUP (List settings for control).
SYSTEM (List settings for system).
These are the different software categories.
Example: HELP SETUP<cr>, will list all the programmable variables and their settings for the SETUP category.
You can interrogate a discrete software command by just typing the command followed by a <cr>.
Figure 10: Test Radio Communication
Example: ADD<cr>, will list the current address saved in the connected ESTeem.
Note Appendix E of this manual will have the complete listing of software commands and categories for the factory
default of the ESTeem.

CHAPTER 1
STARTING OUT
Saving A Program
A program is saved by typing in the SAVE command at the CMD: prompt. The programming variables that have been changed
will be written to the non-volatile memory. The programming parameters will be loaded each time the modem is powered up or
reset.
Restoring Factory Defaults
The ESTeem has a very simple procedure to restore the program variables in the unit to the factory default setting. When the
FA<Enter> command is entered from the command mode the ESTeem will be configured from a variable table located in its
EPROM. It is a good practice to restore the ESTeem to a factory defaults before any programming of the unit.
To ensure the modem is in the COMMAND MODE set it back to the factory default by performing the following:
1. Set both switches (#1&2) on the RS-232 setup switches to the OFF position.
2. Reset the ESTeem.
3. Verify the computer's Comm port is configured for 19,200,N,8,1.
4. Type FA<Enter> and the ESTeem welcome message should be displayed. The characters may not be echoed on the screen.
5. Type SA<Enter> to save the factory default table.
Revised: 15 Oct 03 1-5 EST P/N AA104
CHAPTER 2
MODES OF OPERATION
The ESTeem has three major modes of operation, Command, Converse, and Transparent. This chapter of the manual describes
each one of these modes.
COMMAND MODE
The COMMAND Mode (CMD: prompt) is the default mode that the ESTeem initially enters on power -up or after a hardware or
software reset. From this mode the user can command or program the ESTeem. In this mode the user may access the various
program commands to configure the ESTeem for the specific application. These values can be stored in nonvolatile memory
within the ESTeem by the use of the SAVE command. The ESTeem reads these setup parameters stored in memory on power-up
or RESET.
When programming in the COMMAND Mode, the user need only enter enough characters to uniquely identify the respective
command.
Example: CMD:ADD 15 <Enter>
This enters the source address of the ESTeem to the decimal value of 15. The first three letters ADD were enough for the
ESTeem to uniquely identify the command for ADDress. The number of characters that need to be typed varies depending
upon the command being entered. In some cases, four or even more letters may have to be entered in order for the identification
to be uniquely determined. Up to ten multiple commands can be written on the same line if separated by a colon.
Example: CMD:ADD 15:SETC 2:SAVE <Enter>
CONVERSE MODE
This mode allows bi -directional communication from the input/output device attached to the ESTeem to a destination ESTeem
and its respective input/output device. The ESTeem will automatically switch to the CONVERSE Mode after the initial
CONNECT has been made.
When the ESTeem is in the CONVERSE Mode the * prompt will be displayed. The ESTeem will remain in the CONVERSE Mode
until the radio link has been broken or by typing a control character defined by the user with the COMMAND variable.
The factory default for the COMMAND variable is CTRL C. You can return to the CONVERSE Mode from the COMMAND
Mode by typing CONV <Enter>.
When you are in the CONVERSE Mode the echoing of the character comes from the ESTeem if ECHO = ON (factory default) has
been programmed in the ESTeem.
Transmitting Data
The ESTeem will transmit data from the CONVERSE Mode if one or more of the following conditions have been met.
1. The ESTeem transmit buffer has been filled. The size of the transmit buffer is defined in the ESTeem by the PACKLEN
variable. This variable is programmable from 1 to 2000 bytes. Factory default is 2000.
2. The ESTeem receives a SENDPAC (send packet) character from the RS-232C input data stream. The SENDPAC variable can
be defined from 0 to 255 by the user. Factory default is 13 (carriage return). The SENDPAC character is also transmitted by
the ESTeem. In file dump applications the SENDPAC character can be programmed to be the EOF (end of file) character
transmitted from the sending device (i.e.; CTRL Z, CTRL G, etc.).
Revised: 15 Oct 03 2-1 EST P/N AA104
CHAPTER 2
MODES OF OPERATION
3. Termination control timer. The termination control timer is enabled by the TERMC (on/off) command. When enabled, the
termination timer starts from the time the last transmit buffer has been updated in the RS-232C port. If the termination timer
expires before another character is received or transmitted, the contents of the ESTeem transmit buffer will be transmitted.
The waiting time of the timer is defined by the TERMT variable (termination time). The programming range of the TERMT
variable is 10-65,535ms. Factory default values are TERMC = OFF and TERMT = 50. It is noted that when the termination
timer is used, the SENDPAC variable is usually programmed to be a character that is non occurring in your data stream (i.e.;
SENDPAC = 255) so that premature transmission does not occur.
TRANSPARENT MODE
The TRANSPARENT Mode allows the ESTeem to pass all data characters (O-255 or 0-FF hex) using 8 data bits.
To program the ESTeem in the TRANSPARENT mode the TRANSPARent command must be enabled and switch Bit 2 to ON
(RS-232C Setup Switch). The TRANSPARent command will defeat the SENDPAC and COMMAND variables and put the
ESTeem in the transparent mode when Bit 2 is ON.
The transmission of the data packets can only be accomplished by enabling the termination control commands (TERMC and
TERMT) or the PACKLEN buffer being filled. The value of TERMT should be slightly longer than the maximum delay
encountered during RS-232C transmission. If this time is set to short, the ESTeem will truncate your data stream improperly.
When using the TRANSPARENT Mode, data flow control is by hardware handshaking only. Hardware handshaking is initiated
by enabling hardware flow control (XHF = ON).
The SETCON (Set Connect command) must be used to define the node that you want to communicate with while in the
TRANSPARENT Mode. When the TRANSPARENT Mode is enabled you can not communicate to the ESTeem in the
COMMAND Mode unless you use the Hardware Mode Control line (see explanation this chapter).
To remove the ESTeem from the TRANSPARENT Mode the user must perform the following:
1. Switch Bit 2, Off on the RS-232C Setup Switch.
2. Reset the ESTeem from the front panel switch.
3. Type TRANS OFF <Enter>.
Revised: 15 Oct 03 2-2 EST P/N AA104
CHAPTER 2
MODES OF OPERATION
SEMI-TRANSPARENT MODE
This mode should be utilized when sending a non-ASCII file and there is a possibility that the SENDPAC character could be
contained in the transmitted data set. Perform the following prior to programming the ESTeem to initialize the unit to factory
default settings:
1. Turn Bit 2, OFF on the RS-232C Setup Switch.
2. Reset the ESTeem.
3. TYPE FA <Enter>. Please note the characters may or may not be echoed by the CRT.
ESTeem
-------------------------
ADD xxx xxx = your address
SETC yyy yyy = destination address
TERMC ON
TERMT 10
SENDP 255
EDIT OFF
XSF ON
SAVE
If EDIT is off, and SENDPAC = 255, the SENDPAC character is disabled. This character when received will not cause packet
transmission and will be passed as normal data. The TERMC and TERMT commands are used to transmit the contents of the
ESTeem transmit buffer.
Software flow control in this example is enabled (factory default XSF = OFF) therefore the ESTeem will pass all characters except
the data flow control characters for Xon/Xoff.
HARDWARE MODE CONTROL
The MODECON (Mode Control) command is provided in the ESTeem to change the mode of the ESTeem modem from
COMMAND Mode to CONVERSE (or TRANSPARENT Mode) via a hardware control line. The hardware line is located on pin
19 of the RS-232C connector. If MODEC = ON, a "low or 0" on pin 19 (-3 to -15 vdc) will put the ESTeem in the COMMAND
Mode and a "high or one" on pin 19 ( +3 to +15 vdc) will put the ESTeem in the CONVERSE or TRANSPARENT Mode. The
factory default is OFF.

CHAPTER 3
PROGRAMMING
ESTEEM FEATURES
Listed in this chapter are the major ESTeem features and programming examples on how to use them. These features are
individual building blocks to solve your application needs. Remember your particular application may require one or more of
these features enabled.
DIGI-REPEATING
The Repeater feature allows an ESTeem to relay its respective transmission or packet through a maximum of three ESTeems to
increase the operating range of the unit. Any ESTeem in your radio network can function as a repeater for any other ESTeem.
This is independent of the fact that the ESTeem being used as a repeater is linked or connected to another node, therefore an
ESTeem can function as a repeater, operational node, or both at the same time. The data that is digi -repeated through ESTeem
will not output through the repeating ESTeem’s RS-232C port.
To specify one or more ESTeems as repeaters, the CONNECT command has been expanded to except up to three added
addresses as follows:
CONN r1,r2,r3,da
r1 = Address (1 to 254) of first ESTeem repeater.
r2 = Address (1 to 254) of second ESTeem repeater.
r3 = Address (1 to 254) of third ESTeem repeater.
Da = Address (1 to 255) of destination ESTeem.
Note: Address 255 is used for Global.
When transmitting packets through other ESTeems, the source ESTeem will automatically adjust it's FRACK time to allow
additional time for the packet to reach its destination and for the returned acknowledgment. Frack time takes into account the
packet size and the number of repeaters specified. The ACK still comes from the destination ESTeem, not the first or any
repeater.
For testing purposes, you can loop back a connection to yourself by placing your source address in the destination address of
the repeater string. Any data transmitted will repeat through the repeater address and display back on the screen.
Example:
CONN r1,Sa
r1 = Address (1 to 254) of first ESTeem repeater.
Sa = Address of local ESTeem.
Any ESTeem command in this manual that uses an address string can be configured to use the Digi-repeating feature.
Example:
SETC r1,r2,r3,da

CHAPTER 3
PROGRAMMING
ESTEEM FEATURES
GLOBAL BROADCAST
Global broadcast is the ability of one ESTeem to transmit it's message to more than one ESTeem at one time. All ESTeems within
radio range will receive the message whether or not they are connected to another ESTeem or in command or converse mode.
You can put your ESTeem in Global by connecting or programming the SETC to address 255. Address 255 is a non-assignable
unit address and is used by the ESTeem CPU to access this special mode. When the ESTeem is in Global, the standard ACK
protocol from the receiving ESTeem is disabled, but the 32 bit CRC error checking on the received ESTeem is still operational.
When you perform CONN 255 <Enter> from the COMMAND MODE the ESTeem will immediately go to the CONVERSE MODE
(* is displayed). All messages sent will be transmitted globally to all ESTeems in radio range.
In the ESTeem you have a GLOBAL (on/off) command. When GLOBAL = On, you can receive Global transmissions. If
GLOBAL = Off you will not display Global transmissions from other ESTeems.
Note: Factory default is ON.
By using the repeater function you can transmit Global messages from another ESTeem using the Digi-repeating feature.
Example:
CONN 10,20,30,255<Enter>
SETC 10,20,30,255<Enter>
By adjusting these commands you can route from unit 10 to 20, 20 to 30, and go Global at unit 30.
You can enable global transmissions in one or more ESTeem’s in your network. This will allow global communications between
all ESTeems within radio range.
AUTO TRANSMIT
The Auto Transmit feature of the ESTeem allows the user to transmit a data packet without filling up the PACKLEN (packet
length) buffer or defining a special control character using the SENDPAC (send packet) variable. The Auto Transmit feature is a
timer that is enabled in the ESTeem that monitors traffic in and out of the RS-232C port. If there are characters in the RS-232C
buffer, the termination control timer starts from the time the last receive or transmitted character is updated in the buffer. If the
termination time expires before another character is received or transmitted, the received characters are transmitted.
To enable this feature perform the following from the COMMAND MODE:
TERMC (on/off) = On. Enable termination control.
TERMT (10-65535) = One unit number equals 1ms.
TERMC is the termination control command. TERMT is the termination time command. Factory default for TERMC = Off and
TERMT = 50.

PROGRAMMING
ESTEEM FEATURES
AUTO CONNECT
The Auto Connect feature allows the user to program the ESTeem to perform a CONNECT to another ESTeem when data is sent
to the RS-232C communications port.
To enable this feature perform the following from the COMMAND MODE:
SETCON (1-255) = Address of destination ESTeem.
Remember, you can use the Repeater routing (r1,r2,r3,da) or put the ESTeem in Global (address 255). SETCON is the set connect
command.
SA SAVE command. This will save the SETC variable to the non-volatile memory so that it will not be lost when the
ESTeem is RESET.
Bit 2 (on/off) = On. Bit 2 is located on the RS-232C SETUP SWITCH on the front of the ESTeem. The ESTeem must be
RESET after the Bit has been changed to be read by the ESTeem CPU.
RESET ESTeem RESET is located on the front panel OFF/ON switch. The T/E light on the front panel of the ESTeem should
now flash at a two times per second rate.

PROGRAMMING
ESTEEM FEATURES
MULTI-CONNECT
The actual polling of the ESTeem must originate from the host device connected to the ESTeem using the CONNECT command
to originate the initial connect and the COMMAND character to return from the CONVERSE mode to the COMMAND mode.
The first time around the pole a CONNECT data packet (RF transmission) will be initiated. When a link is established, it is held
internally in the ESTeem connect table. The next time around the pole to the same address, the link status will be checked in the
ESTeem table. If the address indicates a link has already been established, then only data and its corresponding ACK will be
transmitted to that node. This greatly increases polling time by eliminating the usual CONNECT/DISCONNECT sequence each
time except when communication is first established.
The MULTID command allows the user to send data to a specific ESTeem address from the CONVERSE Mode by specifying the
ESTeem address routing before the data packet. This feature will also display the address of the sending ESTeem on any
received data.
Example Of Transmitted Data:
[001]DATA Routes data to an ESTeem addressed 1.
[100,200,250,1]DATA Routes data to an ESTeem addressed 1 via ESTeems addressed 100, 200, and 250.
The above example replaces the CONNECT command from the COMMAND Mode.
Received data packets will have the address of the ESTeem that sent the data at the beginning of the data packet.
Example Of Received Data:
[004]RECEIVED DATA Data received from ESTeem addressed 4.
[030,100,244,004] Data received from ESTeem addressed 4 via ESTeems addressed 30, 100, and 244.
MULTID (on/off) = On Enables this feature. Factory default = OFF.

ESTEEM FEATURES
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.

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 (positi ve 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-Repeater Status, R3-Repeater Status, Data Bytes Sent
xxx = ESTeem Address
DA = Destination ESTeem
SA = Source ESTeem
R1 = Address of first ESTeem repeater.
R2 = Address of second ESTeem repeater.
R3 = Address of third ESTeem repeater.
