2.2 DESCRIPTION

The Model 1009 Asynchronous Short Range Modem lets two

asynchronous RS-232 devices with DB-9 connectors communicate at
distances up to 17 miles. Operating full duplex over two unconditioned
twisted pair, the Model 1009 supports data rates from 300 to 19,200
bps. The Model 1009 draws all necessary operating power from the
RS-232 interface, and requires no AC power or batteries.

The Model 1009 has been designed to connect directly to IBM AT
compatibles, Unisys 6000/7000 Series, NCR "Towers" and other RS­232 machines with DB-9 serial ports. Its ultra-miniature size (2.50" x

1.20" x 0.75") allows the Model 1009 to fit in very tight installation
spaces. Twisted pair connection can be made using RJ-11, RJ-45 or
terminal blocks with strain relief. For added flexibility, the Model 1009 is
compatible with Patton's Model 1000 and 1015 Short Hauls.

The Model 1009S uses the latest in bi-directional, clamping
transient suppressors to guard itself and connected equipment against
data line transients. For surge handling capability, the Model 1009S is
compliant with IEC 801.5, Level 2, 1kV. The Model 1009S is
recommended for environments prone to lightning storms, static
discharge and other forms of EMR.

3.0 INSTALLATION

The Model 1009 is easy to install and requires no pre­configuration. This section tells you how to properly connect the Model
1009 to the twisted pair and RS-232 interfaces, and how to operate the
Model 1009.

3.1 CONNECTION TO THE TWISTED PAIR INTERFACE

The Model 1009 operates full duplex in point-to-point
environments. It passes data as well as X-ON/X-OFF (software)
handshaking signals. There are two essential requirements for
installing the Model 1009:

1. These units work in

pairs

. Therefore, you must have one Model

1009 at each end of a two twisted pair interface.

2. To function properly, the Model 1009 needs two twisted pairs of

metallic wire. These pairs must be

unconditioned

, dry, metallic wire,
between 19 and 26 AWG (the higher number gauges may limit distance
somewhat). Standard dial-up telephone circuits, or leased circuits that
run through signal equalization equipment, are

not acceptable

.

For your convenience, the Model 1009 is available with three
different twisted pair interfaces: RJ-11 jack, RJ-45 jack, and terminal
blocks with strain relief.

3.1.1 TWISTED PAIR CONNECTION USING RJ-11 OR RJ-45

The RJ-11 and RJ-45 connectors on the Model 1009's twisted pair
interface are pre-wired for a standard TELCO wiring environment. The
signal/pin relationships are shown below:

RJ-1

1 SIGNAL RJ-45 SIGNAL

5----------------RCV+ 5 --------------XMT­6----------------GND* 6 --------------RCV+

7 --------------GND*
8 --------------N/C

* Connection to Ground is Optional

When connecting two Model 1009s it is necessary to use a "cross
over" cable. The diagram below shows how a cross over cable should
be constructed for an environment where both Model 1009s use a 6­wire RJ-11 connector. Similar logic should be followed when using RJ­45 connectors or a combination of the two.

3.1.2 TERMINAL BLOCK TWISTED PAIR CONNECTION

If your application requires you to connect one or two pairs of bare
wires to the Model 1009, you will need to access the internal terminal
blocks. The instructions on the following pages will tell you how to
open the case, connect the bare wires to the terminal blocks, and
fasten the strain relief collar in place so that the wires won't pull loose.

Note: The terminal block configurations are different for the 1009M
(male) and 1009F (female).

1. Open the unit by gently inserting a screw driver between the DB­9 connector and the lip of the plastic case (See below). You don't have
to worry about breaking the plastic, but be careful not to bend the D-sub
connector.

Once the unit has been opened, you will be able to see the

terminal block located at the rear of the PC board.

2. Strip the outer insulation from the twisted pairs about one inch

from the end.

Figure 5: Stripping the Outer Insulation from the Twisted Pair

3. Strip back the insulation on each of the 2 twisted pair wires

about .25".

4. Connect

one pair

of wires to XMT+ and XMT- (transmit positive
and negative) on the terminal block, making careful note of which color
is positive, and which color is negative.

5. Connect the

other pair

of wires to RCV+ and RCV- (receive
positive and negative) on the terminal block, again making careful note
of which color is positive, and which color is negative.

Ultimately, you will want to construct a two pair cross over cable that

makes a connection between the Model 1009s as shown below:

6. If there is a shield around the telephone cable, it may be
connected to "G" on the terminal block. We recommend connecting the
shield at the computer end only to avoid ground loops. A ground wire is

not necessary

for proper operation of the Model 1009.

7. When you finish connecting the wires to the terminal block, the
assembly should resemble the diagram below:

8. Place the 2 halves of the strain relief assembly on either side of
the telephone wire and press together very lightly. Slide the assembly
so that it is about 2 inches from the terminal posts and press together
firmly. If your cable diameter is too small or too large for our strain
relief, please contact our technical support. We have strain relief
assemblies to accommodate most cable diameters.

9. Insert the strain relief assembly with the wire going through it
into the slot in the bottom half of the modem case and seat it into the
recess in the case. (If the telephone wire is too thin to be held by the
strain relief assembly, you will need to order a different sized strain
relief. Call Patton's Sales Department at [phone].)

10. BEND the top half of the case as necessary to place it over the

strain relief assembly. Do not snap the case together yet.

11. Insert one captive screw through a saddle washer and then
insert the captive screw with the washer on it, through the hole in the
DB-25 end of the case. Snap that side of the case closed. Repeat the
process for the other side. This completes the cable installation
process.

3.2 CONNECTION TO THE RS-232 INTERFACE

The Model 1009 is configured as a DCE, and is designed to
connect to the DB-9 serial port of an RS-232 DTE (PC, laptop, host).
If you must use a cable to connect the Model 1009 to the DTE device,
make sure that it is a

straight through

cable of the shortest possible

length—we recommend 6 ft or less (See Appendix C).

Should you wish to connect a DTE to a DCE using short range
modems (ex. a PC/AT connecting to a multiplexer several hundred feet
away), we recommend using a Model 1009 for the DB-9 DTE
connection and a Patton Model 1000 for the DB-25 DCE connection.
These two short hauls

are compatible

. If you need to use a Model 1009

on both ends, connection to the DCE device will require a

cross over

RS-232 cable. Call Patton Technical Support at [phone] for
more details.

3.3 OPERATING THE MODEL 1009

Once the Model 1009 is properly installed, it should operate
transparently—as if it were a standard cable connection. Operating
power is derived from the RS-232 data and control signals; there is no
"ON/OFF" switch. All data from the RS-232 interface, including
X-ON/X-OFF flow control information, is passed straight through. Any
hardware flow control signals are looped back at the interface and are
not passed between the short hauls.

APPENDIX B

PATTON MODEL 1009 CABLE RECOMMENDATIONS

The Patton Model 1009 operates at frequencies of 20kHz or less
and has been performance tested by Patton technicians using twisted­pair cable with the following characteristics:

Wire Gauge Capacitance Resistance

19 AWG/.9mm 83nf/mi or 15.72 pf/ft. .0163 Ohms/ft.
22 AWG/.6mm 83nf/mi or 15.72 pf/ft. .0326 Ohms/ft.
24 AWG/.5mm 83nf/mi or 15.72 pf/ft. .05165 Ohms/ft.

To gain optimum performance from the Model 1009 please keep the
following guidelines in mind:

•

Always

use twisted pair wire—this is not an option.

• Use twisted pair wire with a capacitance of 20pf/ft or less.

• Avoid twisted pair wire thinner than 26 AWG (i.e. avoid higher
AWG numbers than 26)

• Use of twisted pair with a resistance greater than the above
specifications may cause a reduction in maximum distance
obtainable. Functionality should not be affected.

• Environmental factors too numerous to mention can affect the
maximum distances obtainable at a particular site. Use “maximum
distance” figures as a general guideline only

.
