with the ESTeem modem. Select the operating
parameters you wish or leave at the default of
9600,N,8,1. Press the control key and the enter key
at the same time (CTRL-Enter) to select your choice.
6. This next section is titled Set RS-232 Switches of the
ESTeem. Press ENTER and the window will display
how the RS-232 switches on the rear of the ESTeem
(Figure 5) need to be set to match the configuration
of the computer’s communication port that we set in
step 5. Configure the switches on the ESTeem to
match those listed in the window and press any key
to continue.
7. Select Turn ESTeem ON. If your power cord and
serial interface cable are installed correctly, the
ESTeem welcome message will be displayed. This
will confirm communications between computer and
the ESTeem. If you do not see the welcome message
or the computer displays an error in communication,
follow the on-line troubleshooting procedure that
will be displayed.
8. Select Attach Antenna & Adjust Squelch from the
menu. This section will give you instructions on
antenna placement and installation. Install antenna
and press the ENTER key to set the squelch.
Proceed to step 9.
9. This section of the utility will set the receiver
squelch on the ESTeem. The ESTeem’s radio
communication protocol will not allow the modem to
transmit if the ESTeem has a solid receive light due
to outside interference. Look on the front of the
modem and adjust the squelch to as high a level as
possible that will keep the receive light out when
other ESTeems are not transmitting. Press ESC to
leave this section.
10. Press Set Address of ESTeem. You must give each
ESTeem an unique address in the system. Type in
the address number and press ENTER to continue.
11. Select Set Transceiver Frequency. This will allow
you to configure the ESTeem’s operating frequency.
Set all ESTeems on the same frequency for
operation within this section. Press CTRL-Enter to
continue.
12. You have just configured all operating parameters
within the ESTeem. If this is your first ESTeem you
have programmed for testing, press the Repeat for
next ESTeem and all check marks will be erased.
Proceed to step 2 and complete all items for the next
ESTeem. If you have at least two ESTeems
programmed and wish to test communication,
proceed to step 13.
13. Press Test Communication Between ESTeems. This
section will allow you to test the radio frequency
(RF) communications between two or more
ESTeems. Two types of tests are listed in this
window (Figure 6). If you have a computer attached
to both ESTeems proceed to step 14 and if you only
have one computer to test both ESTeems proceed to
step 15.
14. The first test will be used if you have a computer
attached to both ESTeems. Select the first of two
items and press ENTER. Follow the instructions on
the screen to establish a communication link between
modems.
15. This second test will allow you to use the remote
ESTeem as a digi-repeater for your local modem.
This procedure is explained in the window and can
test communication with only one computer.
16. You now have competed the basic programming and
setup of your ESTeem modems. You have tested
their operation with each other and are now ready to
proceed in programming them for your application.
Press Exit to Main Menu and continue with the
programming of the ESTeem for your application.
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.
Communication Test
To perform this test, please select one of the
following test configuration:
[ ] Establish communications link from the ESTeem
connected to this computer to another
ESTeem/computer pair.
[ ] Loop Back Test from the ESTeem connected
to this computer to a remote ESTeem.
