INTRODUCTION
The AOR Model AR-210 Terminal Node Controller is designed as a link between your radio trans-
ceiver and a simple data terminal (or personal computer). This Terminal Node Controller (TNC) al-
lows you to operate new computer-based communications mode – "Packet-Radio". You will find
this unit convenient and easy to use.
The most unique and important feature of Packet-Radio transmissions, unlike RTTY, is that they are
virtually error free. Information that you intend to transmit is first made into digital groups, or
packets. Confirmation of correct reception of these packets is then returned to the originating sta-
tion by the destination station. If the originating station does not receive confirmation, it automati-
cally resends the packets until the correct information is confirmed, or the contact is terminated.
A modem (modulator / demodulator) that can operate at very high baud rates is included in the
unit. This results in very short transmissions by each station and allows several stations to use the
frequency at the same time. Also, due to the choice of operating parameters, you are not aware of
the presence of other stations on frequency.
The unit also functions as an automatic repeater. You may use it as an unattended repeater, a bea-
con or a "mailbox" with the appropriate computer and software. You may also use it with a FSK or
AFSK FM station on the VHF and UHF bands.
In addition to your radio equipment, you will need either an ASCII data terminal or a personal
computer that has an RS-232C output and uses a terminal emulator program. Such programs are
widely available for connecting your computer to a modem like the Hayes Smart modem. They are
often used to access CompuServe, GEnine o other computer telephone service.
The demonstration terminal software supplied with the AR-210 package is for the IBM PS/2,
PC/XT/AT and compatible computers.
A 9 pin straight computer cable supplied with the AR-210 is for the IBM AT or compatible comput-
ers, but you may need a different cable and connectors if the supplied cable does not fit your com-
puter.

1. INSTALLATION
Before you can perform the "Operational Test and Alignment", which follows in this section, you
will have to properly connect your AR-210 (thereafter called TNC) to a terminal or a computer and
run the proper terminal emulation program.
In addition, you will have to connect the TNC to you radio equipment, read and comply with the
following information that pertains to your situation under "Computer Connections", "Software Re-
quirements" and "Radio Connections".
If you use a computer you will need a terminal emulator or communications program such as Pro-
com, Procomm Plus or accessory terminal program that comes with MS Windows.
A sample terminal program supplied with the TNC can be used for the IBM PS/2, PC, XT, AT and
compatible computers running under MS DOS.
Since these programs allow a computer to operate like a terminal, the following information
will use the term "Computer" to refer to a computer or a terminal.
The TNC communicates with your computer through a serial port using signals that correspond to
the RS-232C standard. Most computers that are available today either incorporate an RS-232C
style serial port, or have one available as an accessory. If you have already been using your com-
puter with an RS-232C modem, you can use this TNC the same way.
COMPUTER CONNECTIONS
Table 1-1 shows the minimum connections that are required between the RS-232 I/O connector on
the rear of the TNC and your computer. These minimum connections do not permit hardware flow
control. DO NOT connect any wires other than pins 1 through 8 and 20 if your computer I/O is a
DB-25 style connector. Pins 17 through 19 and 21 through 25 are reserved for future use.
The supplied cable i for the IBM PS/2, AT and 100 % compatible computers with DB-9S asynchro-
nous communication port (serial port) connector.
You may also consider using a 9-to-25 pin adaptor for connecting to a 25-pin serial port computers
such as the IBM PC, XT and compatibles.
IMPORTANT: Whether you purchase a ready-made cable or make your own, make sure that it
is a SHIELDED cable.

OTHER COMPUTERS WITH 25-PIN RS-232C PORTS
If your computer has a 25-pin RS-232C port, refer to its manual to determine the transmit data,
receive data and signal ground pins. Follow the manufacturers recommendations for connecting
the serial port to a modem.
AR-210 Manual 1-3

Your TNC is configured as Data Communications Equipment (DCE), while most computers are con-
figured as Data Terminal Equipment (DTE). If this is true of your particular computer, you can
probably connect pins 2, 3 and 5 of your TNC to pin 3, 2 and 7 respectively of your computers RS-
232C port.
If your computer is configured as DCE, you will have to cross the wires between pins 2 and 3 of
the TNC. In other words, connect pin 2 of the TNC to pin 2 of he computer and pin 3 of the TNC
to pin 3 of the computer. The signal ground is the same (pin 5 of the TNC to pin 7 of the com-
puter).
Some computers may require that you connect pin 5 of the serial port connector to an appropriate
signal. Others may require connections to pin 8 and 20. You can use the computers output signals
on pin 4 and 6 for this purpose as shown in table 1-5.

OTHER COMPUTERS WITH NONSTANDARD SERIAL PORT
Computers with non standard serial ports must meet the following conditions:
1. The signal levels should be RS-232C compatible. The TNC requires that the voltage levels that
come from the computer be greater than +3 volts in one state and less than 0 volts in the
other state.
2. The polarity of the signals must conform to the RS-232C standard. A lower voltage state must
correspond to a logical "1" and a higher voltage state to a logical "0".
3. The computer must be able to correctly receive a signal which meets the RS-232C specifica-
tion. The TNC supplies signals that meet this specification.
Make or purchase a cable that provides the necessary connections. The serial port common pin
must be connected to the TNCs serial port connector at pin 5. The data line that sends data FROM
the computer must be connected to the TNCs connector at pin 3. The line that your computer uses
to RECEIVE data must be connected to the TNCs connector at pin 2.
If your computer requires any other signals, you must find ways of providing them. The documen-
tation provides with your computer or its accessory serial port should specify any special require-
ments of your particular port.

SOFTWARE REQUIREMENTS
Any software package that enables your computer to act as an ASCII terminal with an ordinary te-
lephone modem should work with your TNC. If you have a program that you have successfully
used with a telephone modem, and you are familiar with its operation, use that same program to
communicate with the TNC.
