1.1 RADIO AND TV INTERFERENCE
The Model 1065RC generates and uses radio frequency energy,
and if not installed and used properly—that is, in strict accordance with
the manufacturer’s instructions—may cause interference to radio and
television reception. The Model 1065RC has been tested and found to
comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that interference will not occur in a particular installation. If the Model 1065RC
does cause interference to radio or television reception, which can be
determined by turning the power off or removing the card, the user is
encouraged to try to correct the interference by one or more of the following measures: moving the computing equipment away from the
receiver, re-orienting the receiving antenna and/or plugging the receiving equipment into a different AC outlet (such that the computing
equipment and receiver are on different branches).

2.2 DESCRIPTION
The Model 1065RC Series Universal Short Range Modem oper-
ates 2-wire (half duplex) or 4-wire (full or half duplex), in synchronous
or asynchronous modes at an extended range of 12 miles. It operates
at data rates to 64.0 kbps. The Model 1065RC
always
operates in
sync. mode between the local and remote modems; when connected to
an async. RS-232 device, the Model 1065RC converts the async. data
to sync. data
The Model 1065RC has several features to enhance overall performance: equalization, antistreaming timer, transformer isolation and
Silicon Avalanche Diode surge protection. The Model 1065RC features
V.52 compliant bit error rate patter n tests and two V.54 test modes.
The Model 1065RC is designed to mount in Patton’s 2U high 19”
rack chassis. This 14-card chassis has a switchable 120VAC/240VAC
power supply and mounts cards in a mid-plane architecture.The front
card can be plugged into different rear cards. This means that the
Model 1065RC card can have several interface options and can be
switched with other Patton short haul cards.
NOTE: Packages received without an RMA number will
not be accepted.
3.2 CONFIGURATION SWITCH SET “S1”
The DIP switches on S1 set data rate, clock source, async./sync.
mode and carrier control method. The default settings are summarized
in Figure 4.
S1-1 through S1-4: Data Rate Setting
Switches S1-1 through S1-4 and S3-3 are set in combination to

3.0 CONFIGURATION
This section describes the location and orientation of the Model
1065RC’s configuration switches and provides detailed instructions on
setting each of the switches.
The Model 1065RC uses 24 DIP switches that allow configuration
to an extremely wide range of applications. These 24 DIP switches are
accessible when the card is slid out of the rack chassis. Once configured, the Model 1065RC is designed to operate transparently, without
need for frequent re-configuration: just set it and forget it!
3.1 SWITCH LOCATIONS AND ORIENTATION
The Model 1065RC has three sets of eight switches—S1, S2, and
S3—which are mounted on the PC board (Figure 1). These 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, antistream control and input impedance.
As Figure 2 shows, the orientation of all DIP switches is the same with
respect to “ON” and “OFF” positions.

3.5 REAR CARD CONFIGURATION
The Model 1065RC has two interface card options: DB-25/RJ-11
and DB-25/RJ-45. Each of these options supports one RS-232 connection and one 4-wire connection. Figure 8 illustrates the two different interface options for the Model 1065RC.
Prior to installation, you will need to examine the rear card you
have selected and make sure it is properly configured for your application. Each rear card is configured by setting straps located on the PC
board. Section 3.5.1 describes the strap locations and possible settings for each rear card.
3.5.1 REAR CARD STRAP SETTINGS
Figure 9 shows strap locations for the Model 1000RMC12511
(DB-25/RJ-11) and the Model 1000RMC12545 (DB-25/RJ-45) rear
cards. These straps determine various grounding characteristics for
the RS-232 and twisted pair lines.
Figure 10 shows the orientation of the rear interface card straps.
The strap can either be on pegs 1 and 2, or on pegs 2 and 3.
Figure 11 below provides an overview of interface strap functions
for the rear interface cards. Following this overview is a detailed
description of each strap’s function.

4.0 INSTALLATION
This section describes the functions of the Model 1001R14P rack
chassis, tells how to install front and rear Model 1065RC cards into the
chassis, and provides diagrams for wiring the interface connections
correctly.
4.1 THE MODEL 1001R14P RACK CHASSIS
The Model 1001R14P Rack Chassis (Figure 12) has sixteen short
range modem card slots, plus its own power supply. Measuring only
3.5” high, the Model 1001R14P is designed to occupy only 2U in a 19”
rack. Sturdy front handles allow the Model 1001R14P to be extracted
and transported conveniently.
4.1.1 THE RACK POWER SUPPLY
The power supply included in the Model 1001R14P rack uses the
same mid-plane architecture as the modem cards. The front card of
the power supply slides in from the front, and the rear card slides in
from the rear. They plug into one another in the middle of the rack.
The front card is then secured by thumb screws and the rear card by
conventional metal screws.
Switching the Power Supply On and Off
The power supply on/off switch is located on the front panel.
When plugged in and switched on, a red front panel LED will glow.
Since the Model 1001R14P is a “hot swappable” rack,
it is not neces-
sary for any cards to be installed before switching on the power supply
.
The power supply may be switched off at any time without harming the
installed cards. Be sure power is off before power module card is
removed.
Figure 12. Model 1001R14P Rack Chassis with power supply
17 18
Replacing the Power Supply Fuse
The rack chassis power supply uses a 1.5A, 250V fuse.The fuse
compartment is located just below the AC socket on the rear card.to
replace the fuse, follow these three steps:
1. Using a small screw driver, pop the compartment open.It will
slide open like a drawer. Depending upon the exact part used,
the drawer may slide completely out of the fuse holder or it
may stop partway out.
2. There are two fuses in the drawer.The front fuse is the spare
and the rear fuse is the “active” fuse.
3. If the active fuse appears to be blown, remove it from the clips
and replace it with the spare, which is located in the front
compartment. Note the size and rating of the blown fuse
before discarding.
4. Using the part number found in Appendix C, order a new
replacement fuse* from Patton Electronics.You may also
choose to buy a replacement fuse from a nearby electronics
store.
4.2 INSTALLING THE MODEL 1065RC INTO THE CHASSIS
The Model 1065RC is comprised of a front card and a rear card.
The two cards meet inside the rack chassis and plug into each other by
way of mating 50 pin card edge connectors. Use the following steps as
a guideline for installing each Model 1065RC into the rack chassis:
1. Slide the rear card into the back of the chassis along the
metal rails provided.
2. Secure the rear card using the metal screws provided.
3. Slide the card into the front of the chassis. It should meet the
rear card when it’s almost all the way into the chassis.
4. Push the front card
gently
into the card-edge receptacle of the
rear card. It should “click” into place.
5. Secure the front card using the thumb screws.
4.3 WIRING THE MODEL 1065RC
Each of the rear interface cards compatible with the Model
1065RC has one RS-232 port and one 4-wire (twisted pair) port.
These cards provide a female DB-25 for RS-232 connection.
4.3.1 RS-232 CONNECTION
The Model 1065RC uses a DB-25 female to connect the RS-232
interface to your computing hardware. It is pinned according to the
RS-232C/V.24 interface standard. For specific interface pin-outs,
please refer to the diagrams in Appendix D of this manual.
The Model 1065RC is wired to connect to a DTE. If your RS-232
output device is a DTE, use a
straight though cable
to connect to the
Model 1065RC. If your RS-232 output device is DCE, call Technical
Support at (301) 975-1007 for specific installation instructions.
NOTE: Since the Model 1001R14P chassis allows “hot swap-
ping” of cards, it is
NOT NECESSARY TO POWER DOWN
the
rack when you install or remove a Model 1065RC.
*WARNING: For continued protection agaisnt the risk of
fire, replace only with the same type and rating of fuse.
19 20
4.3.2 TWISTED PAIR CONNECTION
The Model 1065RC operates over one or two twisted pair. In
all
applications, the twisted pair wire must be 26 AWG or thicker, unconditioned, dry, metallic wire. Both shielded and unshielded wire yield
favorable results. Note: The Model 1065RC communicates in a
closed data circuit with another Model 1065RC or other compatible
modem. Dial-up analog circuits, such as those used with a standard
Hayes-type modem, are
not acceptable.
For further information about
acceptable wire grades, please refer to the diagrams in Appendix B.
Point-to-Point Twisted Pair Connection
The 6-position RJ-11 and 8-position RJ-45 jack options for the
Model 1065RC are prewired for a standard TELCO wiring environment.
Connection of a 4-wire twisted pair circuit between two or more Model
1065RCs requires a
crossover cable

5.0 OPERATION
Once you have configured each Model 1065RC 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 LED STATUS MONITORS
The Model 1065RC features six front panel status LEDs that indicate the condition of the modem and communication link. Figure 15
shows the front panel location of each LED. Following Figure 15 is a
description of each LED's function.
5.1.1 The “TD” and “RD” Indicators
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 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 green “Test” LED indicates that V.52 or V.54 tests are running.
5.1.4 The “Error” Indicators
The “Error” indicator LED has two functions:
A. When the 1065RC is in test mode (green “Test” LED is lit), the
error LED glows red when bit errors occur.
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 antistreaming circuitry.
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
1065RC’s antistreaming 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
timeout period, the antistream 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
computer port in a multidrop or polling environment. When the DTE
drops RTS, the antistreaming timer is automatically reset and the front
panel “Error” LED turns off. The timeout period is DIP switch selectable
for 12.5 or 50 seconds.
5.3 POWER-UP
There is no power switch on the Model 1065RC: Power is automatically applied to the Model 1065RC when its card-edge connector
makes contact with the chassis’ mid-plane socket, or when the chassis’
power supply is turned on.
Note:The Model 1065RC is a “hot swappable” card—it will not be damaged by plugging it in or removing it
while the rack is powered up.
When the local and remote Model 1065RCs are
both
powered up
and are passing data
normally
, the following LED conditions will exist:
• PWR = green
• TD & RD = flashing off and on (green)
• RTS & CD = green
• TEST = off
5.4 TEST MODES
The Model 1065RC offers two V.54 test modes and two V.52 test
modes to evaluate the condition of the modems and the communication link. Both sets of tests can be activated physically from the front
panel.The V.54 test can also be activated from the RS-232 interface.
Note:V.54 and V.52 test modes on the Model 1065RC are available for
point-to-point applications only.
5.4.1 LOCAL ANALOG LOOPBACK (LAL)
The Local Analog Loopback (LAL) test checks the operation of the
local Model 1065RC, and is
performed separately on each unit.
Any
DTE data sent to the local Model 1065RC 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:
1. Activate LAL. This may be done in one of two ways:by moving the upper front panel toggle switch RIGHT to “Analog”or
by raising pin 18 on the RS-232 interface (note:be sure DIP
switch S3-5 is enabled). Once LAL is activated, the Model
1065RC transmit output is connected to its own receiver. The
“Test” LED should be lit.
2. Verify that the data terminal equipment is operating properly
and can be used for a test.
3. Locate the lower of the two toggle switches on the front panel
of the Model 1065RC and move it to the right. This will activate the V.52 BER test mode and inject a “511” test pattern
into the local loop. If any errors are present in the loop, the
red “Error” LED will blink sporadically.
4. If the BER test indicates
no errors
are present, move the V.52
toggle switch to the left, thus activating the “511/E” test with
periodic errors. If the test is working properly, the red “Error”
LED will blink
regularly
. A successful “511/E” test will confirm
that the loop is in place, and that the Model 1065RC’s built-in
“511” generator and detector are working properly.
5. If the BER test indicates that errors
are
present, check to see
that the RS-232 cable connecting the DTE to the Model
1065RC is wired straight through, and is plugged in properly.
Also, ensure that the Model 1065RC is configured properly.
Then re-check your DTE equipment. If you still have errors,
call Patton Technical Support at (301) 975-1007.
25 26
5.4.2 REMOTE DIGITAL LOOPBACK (RDL)
The Remote Digital Loopback (RDL) test checks the performance
of both the local and remote Model 1065RCs,
and
the communication
link between them. Any characters sent to the remote 1065RC 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 1065RC and looped back. To perform an RDL test, follow these
steps:
1. Activate RDL. This may be done in two ways:by moving the
upper front panel toggle switch LEFT to “Remote”or by raising
pin 21 on the RS-232 interface.
2. Verify that the DTE equipment on the local end is operating
properly and can be used for a test.
3. Locate the lower of the two toggle switches on the front panel
of the 1065RC and move it to the right. This will activate the
V.52 BER test mode and inject a “511” test patter n into the
remote loop. If any errors are present in the loop, the red
“Error” LED will blink sporadically.
4. If the BER test indicates
no errors
are present, move the
V.52 toggle switch to the left, thus activating the “511/E” test
with periodic errors. If the test is working properly, the red
“Error” LED will blink
regularly
. A successful “511/E” test will
confirm that the loop is in place, and that the Model 1065RC’s
built-in “511” generator and detector are working proper ly.
5. If the remote BER test indicates that errors
are
present, and
the local analog loopback/BER tests showed that both Model
1065RCs were functioning properly, this suggests a problem
with the twisted pair communication line connecting the two
modems. A common problem is improper crossing of the
pairs. Also, verify that the modular connections are pinned
properly, and the twisted pair line has continuity. If you still
have errors, call Technical Suppor t at (301) 975-1007.
5.4.3 USING THE V.52 BER TEST INDEPENDENTLY
The Model 1065RC's V.52 BER test can be used independent of
the V.54 loopback tests. This requires two operators: one to initiate and
monitor the test at both the local and the remote Model 1065RC. To
use the V.52 BER test by itself, both operators should simultaneously
follow these steps:
1. Locate the lower of the two toggle switches on the front panel
of the Model 1065RC and move it to the right. This will activate the V.52 BER test mode and transmit a “511” test pattern
to the other unit. If any errors are present, the receiving
modem’s red “Error”LED will blink sporadically. Note: For this
independent test to function, the “511” switch on
both
Model
1065RCs must be turned on.
2. If the test indicates no errors are present, move the V.52 toggle switch to the left, thus activating the “511/E” test with periodic errors present. If the test is working properly, the receiving modem’s red “Error”LED will blink
regularly
. A successful
“511/E” test will confirm that the link is in place, and that the
Model 1065RC’s built-in “511” generator and detector are
working properly.

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 or larger (smaller AWG#).
Patton products are designed to withstand normal environmental
noise and conditions however, other environmental factors too numerous to discuss 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. Cer tain
models are better suited for particular applications and environments
than others.
