2.0 GENERAL INFORMATION  
3.0 CONFIGURATION OVERVIEW  
Thank you for your purchase of this Patton Electronics product.  
This product has been thoroughly inspected by Patton's qualified tech-  
nicians. If any questions or problems arise during installation or use of  
this product, please do not hesitate to contact Patton Electronics  
Technical Support at (301) 975-1007.  
The Model 1065 is fairly simple to install and is ruggedly designed  
for excellent reliability: just set it and forget it. The following instruc-  
tions will help you set up and install the Model 1065 properly.  
3.1 CONFIGURATION SWITCHES  
2.1 FEATURES  
The Model 1065 uses 24 external mini DIP switches that allow  
configuration to an extremely wide range of applications. These 24  
DIP switches are grouped into three eight-switch sets, and are exter-  
nally accessible from the underside of the unit (see Figure 1). Since all  
configuration DIP switches are externally accessible, there is no need  
to open the case for configuration.  
• Synchronous or asynchronous operation  
Model 1065 supports data rates up to 64.0 kbps  
• Two-wire/half duplex or four-wire/full or half duplex  
V.52 & V.54 test modes  
• Equalization  
• Anti-streaming timer  
• Distances up to 12 miles (19.2 km)  
• Point-to-point or multipoint  
• Internal, external or received loopback clocking  
• 2000 VAC transformer isolation & high speed surge protection  
• Internal power supply  
The configuration switches allow you to select data rates, clocking  
methods, V.52 & V.54 tests, word lengths, extended signaling rates,  
async. or sync. mode, 2- or 4-wire operation, anti-stream control and  
input impedance. The drawings, text and tables on the following pages  
describe all switch locations, positions and functions.  
• Mono-color LED indicators  
2.2 DESCRIPTION  
The Model 1065 Industrial Short Range Modem operates 2-wire  
(half duplex) or 4-wire (full or half duplex), in synchronous or asyn-  
chronous modes, over unconditioned telephone lines. The Model 1065  
supports bit rates up to 64.0 kbps. The Model 1065 operates in syn-  
chronous mode between the local and remote modems; when connect-  
ed to an asynchronous RS-232 device, the Model 1065 SRM converts  
the asynchronous data to synchronous data.

The Model 1065 has several features to enhance overall perform-  
ance: equalization, anti-streaming timer, transformer isolation to guard  
against data loss due to ground potential differences, and Silicon  
Avalanche Diode surge protection to guard against data line transients.  
The Model 1065 features V.52 compliant bit error rate pattern tests  
and two V.54 test modes: local analog loopback and remote digital  
loopback. The operator at the local end may test both local and  
remote modems, plus the line, in the digital loopback mode. Both RDL  
and LAL modes can be controlled by a manual switch or via the  
V.24/RS-232 interface.

Switch S3-3: Rate Selection  
Switches S3-1 & S3-2: Input Impedance  
Use Switch S3-3 to select the timing mode of the 1065. To oper-  
ate the 1065 at 16, 32, or 64kbps, set S3-3 to the On position. To  
select any other DTE rate, set Switch S3-3 Off.  
The setting for Switches S3-1 and S3-2 determines the 1065  
Series’ input impedance. This allows you to choose the optimum  
impedance setting for your application. In long distance applications  
the impedance of the cable must match the impedance of the load (or  
resistor) of the Model 1065 Series unit. Thicker gauge cables requires  
a lower Ohm setting, while a thinner gauge cable should receive a  
higher Ohm setting. If you are using higher speeds you will need a  
lower Ohm setting, and a higher Ohm setting for the slower speeds.  
Refer to the table on the following page for assistance in selecting a  
setting.

Switch S3-5: RS-232 Initiation of Local Loopback Test  
4.0 INSTALLATION  
The setting for switch S3-5 determines whether or not the Model  
1065 local analog loopback test can be initiated by raising pin 18 on  
the RS-232 interface.  
The Model 1065 operates in four twisted pair topologies:  
2-wire/point-to-point, 2-wire/multipoint, 4-wire/point-to-point, and  
4-wire/multipoint. In each of these topologies, the twisted pair wire  
must be 19 - 26 AWG "dry", unconditioned metallic wire (see Appendix  
C for wire recommendations). Dial-up analog circuits, such as those  
used with a standard Hayes-type modem, are not acceptable. The  
twisted pair may be shielded or unshielded. Both types yield favorable  
results.

rear panel of the Model 1065 Series. Connect the wire to each Model  
1065 Series as described in the instructions that follow the illustration.  
The “+” and “-” indicators are for reference only.

4.1 TWO-WIRE INSTALLATION  
When communicating over a single twisted pair circuit, the Model  
1065 operates half duplex: that is, it transmits in only one direction at  
a time. This method of operation is effective for both point-to-point and  
multipoint applications.  
In single pair point-to-point applications, you will need a pair of  
Model 1065s for each circuit—one at each end of the single pair wire.  
In single-pair multipoint applications you will need three or more Model  
1065 units. These can be connected using a star topology, although a  
daisy chain topology is usually used.

4.2 FOUR-WIRE INSTALLATION  
4.1.1 Two-Wire Cable Connection Via RJ-45  
When communicating over a two twisted pair circuit, the Model  
1065 can operate full or half duplex, point-to-point or multipoint. In two  
pair point-to-point applications, you will need a pair of Model 1065s for  
each circuit—one at each end of the two pair cable. In two pair multi-  
point applications you will need three or more Model 1065 units. These  
can be connected using a star topology, although a daisy chain topolo-  
gy is usually used.

4.3.1 Multipoint Twisted Pair Connection  
The Model 1065 supports multipoint applications using a star topol-  
ogy. Maximum distance between the units will vary based upon the  
number of drops, data rate, wire gauge, etc. Call Patton Technical  
Support for specific distance estimates. Figures 5 and 6 show how to  
wire the one-pair and two-pair cables properly for a Model star topolo-  
gy. Note that the ground connection is not needed.

4.3 FOUR-WIRE, MULTIPOINT INSTALLATION  
Multipoint operation involves the connection of several terminals to  
one host port. In such an application, one local Model 1065 is used as  
a master unit, and it is connected to several remote Model 1065s that  
are acting as slaves.

FIRST SLAVE  
SECOND SLAVE  
XMT-----------------------------RCV  
------------------------------------------------------------------RCV  
In a multipoint environment the master Model 1065 transmits con-  
tinually. Initiation of two-way communication is RTS controlled by each  
“slave” Model 1065 unit. To facilitate multipoint communication, the  
master Model 1065 should have its carrier control DIP switch set to  
“constantly ON” (S1-8=OFF). Each slave Model 1065 unit should have  
its carrier control DIP switch set to “controlled by RTS” (S1-8=ON).  
Figure 5 illustrates a typical Model 1065 multipoint application.

4.4 RS-232 CONNECTION  
Connect the synchronous or asynchronous output of your RS-232  
device to the DB-25 interface on the rear panel of the Model 1065.  
Note: The Model 1065 is wired to connect to a DTE. If your RS-232  
output device is DCE, call Patton Technical Support at: (301) 975-  
for specific installation instructions.

5.0 OPERATION  
Once you have configured each Model 1065 Series unit properly  
and connected the twisted pair and RS-232 cables (see Section 4.0),  
you are ready to operate the units. This section describes reading the  
LED status monitors, powering-up and using the built-in V.52 and V.54  
test modes.  
5.1.4 The “Error” Indicators  
The “Error” indicator LED has two functions:  
A. When the 1065 unit is in test mode (green “Test” LED is lit), the  
error LED glows red when bit errors occur.  
5.1 LED STATUS MONITORS  
B. When not in test mode (green “Test” LED is off), the error LED  
is used to indicate an RTS streaming condition. (See Section 5.2) for  
information on the anti-streaming circuitry.  
The Model 1065 Series features seven front panel status LEDs that  
indicate the condition of the modem and communication link. Figure 5  
shows the front panel location of each LED. Following Figure 6 is a  
description of each LED's function.  
5.2 ANTI-STREAMING ERROR INDICATOR  
When not in test mode (green “Test” LED is off), the front panel  
“Error” LED is used to indicate a streaming error. When the Model  
1065s’ anti-streaming circuitry is enabled, the RTS signal from the DTE  
is timer controlled. The timer begins to count when the DTE raises  
RTS. If the time period that RTS remains high exceeds the preset time  
out period, the anti-stream circuit will force RTS low. The “Error” LED  
will light red, indicating a streaming condition (RTS continually on).  
This feature prevents a malfunctioning terminal from tying-up a com-  
puter port in a multi-drop or polling environment. When the DTE drops  
RTS, the anti-streaming timer is automatically reset and the front panel  
“Error” LED turns off. The time out period is DIP switch selectable for  
12.5 or 50 seconds.

5.1.1 The “TD” and “RD” Indicators  
The Power LED glows green to signal power present. The “TD” and  
“RD” indicators blink green with data activity. Off indicates a low RS-  
232 logic level, green indicates a high RS-232 logic level. Note: RS-  
232 devices idle in a low state, so the LED will be off if the connections  
are correct and the RS-232 device is in an idle state.  
5.1.2 The “RTS” and “CD” Indicators  
The “RTS” and “CD” indicators are monocolor and will be off for a  
“low” signal or green for a “high” signal. RTS lights for an incoming  
signal on RS-232 pin 4. CD lights for an incoming signal on the line  
side, and the resulting output signal on RS-232 pin 8.  
5.1.3 The “Test” Indicator  
The yellow“Test” LED indicates that V.52 or V.54 tests are running.

5.3 POWER-UP  
5.4.2 Remote Digital Loopback (RDL)  
Apply AC power to the Model 1065 by plugging the separate AC  
power cable first into the rear panel of the Model 1065 and then into an  
acceptable AC power outlet. The remote/normal/loopback switch  
should be set to “normal”. When the local and remote Model 1065 are  
poweyellow up, and passing data normally, the following LED condi-  
tions will exist:  
The Remote Digital Loopback (RDL) test checks the performance  
of both the local and remote Model 1065s and the communication link  
between them. Any characters sent to the remote 1065 in this test  
mode will be returned back to the originating device. For example,  
characters typed on the keyboard of the local terminal will appear on  
the local terminal screen after having been passed to the remote  
Model 1065 and looped back. To perform an RDL test, follow these  
steps:  
• TD & RD = flashing on and off  
• RTS & DCD = green  
• TEST = off  
A. Activate RDL. This may be done in two ways: By moving the  
front panel toggle switch UP to "Remote" or by raising pin 21 on the  
RS-232 interface (Note: Make sure DIP switch S3-6 is ON; and DIP  
switch S2-6 is OFF).  
5.4 V.54 TEST MODES  
The Model 1065 offers two V.54 test modes to evaluate the condi-  
tion of the modems and the communication link. These tests can be  
activated physically from the front panel, or via the RS-232 interface.  
Note: V.54 test modes are available for point-to-point applications only.  
B. Perform a BER (bit error rate) 511/511E test on the system.  
C. If the BER test equipment indicates a fault, and the Local  
Analog Loopback test was successful for both Model 1065 Series  
units, you may have a problem with the twisted pair line between the  
modems. You should then test the twisted pair line for proper connec-  
tions and continuity.  
5.4.1 Local Analog Loopback (LAL)  
The Local Analog Loopback (LAL) test checks the operation of the  
local Model 1065 Series unit, and is performed separately on each  
unit. Any data sent to the local Model 1065 in this test mode will be  
echoed (returned) back to the user device. For example, characters  
typed on the keyboard of a terminal will appear on the terminal screen.  
To perform a LAL test, follow these steps:  
5.4.3 Using the V.52 BER Test Independently  
The V.52 BER test can be used independently of the V.54 loopback  
tests. This requires two operators: one to initiate and monitor the test  
at the local Model 1065, and one at the remote Model 1065. To use the  
V.52 BER test by itself, both operators should simultaneously follow  
these steps:  
A. Activate LAL. This may be done in one of two ways: By mov-  
ing the front panel toggle switch DOWN to "Local" or by raising pin 18  
on the RS-232 interface (Note: Make sure DIP switch S2-6 is OFF,  
and DIP switch S3-5 is ON). Once LAL is activated, the Model 1065s  
transmit output is connected to its own receiver. The "test" LED should  
be lit.  
1. Locate the “511/511E” toggle switch on the front panel of the unit  
and move it UP. This activates the V.52 BER test mode and trans-  
mits a “511” test pattern to the other unit. If any errors are pres-  
ent, the receiving modem's red “ERROR” LED will blink sporadi-  
cally. Note: For this test to function, the “511” switch on both  
Model 1065 units must be on.  
B. Verify that the data terminal equipment is operating properly and  
can be used for a test. If a fault is indicated, call a technician or  
replace the unit.  
2. If the test indicates no errors are present, move the V.52 toggle  
switch DOWN, activating the “511/E” test with periodic errors pres-  
ent. If the test is working properly, the receiving modem’s yellow  
“ERROR” LED will blink regularly. A successful “511/E” test will  
confirm that the link is in place, and that the Model 1065s’ built-in  
“511” generator and detector are working properly.  
C. Perform a BER (bit error rate) or 511/511E test on each unit. If  
the BER test equipment indicates no faults, but the data terminal indi-  
cates a fault, follow the manufacturer's checkout procedures for the  
data terminal. Also, check the RS-232 interface cable between the ter-  
minal and the Model 1065.

We fully expect that the Short Range Modems will operate on lines  
with specifications different from those tested, but to reduce the potential  
difficulties in the field, one should ensure that the cable being used has  
similar or better characteristics (lower capacitance or lower resistance).

Wire with capacitance of 20pF/ft. or less is suitable for all our Short  
Range Modems however, distances may vary from those published in our  
catalog. Resistance will also affect distance but not functionality. Wire  
should be 26 AWG (.4mm) or larger (smaller AWG#).  
Patton products are designed to withstand normal environmental noise  
and conditions however, other environmental factors too numerous to dis-  
cuss in this format may affect proper operation of the SRM’s.  
Selection of the proper SRM for an application is critical to maintaining  
Customer Satisfaction and should be taken seriously. Certain models are  
better suited for particular applications and environments than others.
