2.0 GENERAL INFORMATION  
3.0 CONFIGURATION  
Thank you for your purchase of this Patton Electronics product.  
This product has been thoroughly inspected and tested and is  
warranted for One Year parts and labor. If any questions arise during  
installation or use of the unit, contact Patton Electronics Technical  
Support: (301) 975-1007.  
This section describes the location and orientation of the Model  
1018RC’s configuration switches and jumpers, and provides detailed  
instructions for all possible settings.  
The Model 1018RC uses a combination of DIP switches and  
jumpers that allow configuration to an extremely wide range of  
applications. Designed around a mid-plane architecture, the Model  
1018RC incorporates both front and rear cards. Configuration of both  
may be necessary. The switches/jumpers are accessible when the  
cards are slid out of the rack chassis. Once configured, the Model  
1018RC is designed to operate transparently, without need for frequent  
re-configuration: just set it and forget it!  
2.1 FEATURES  
• Switch-selectable carrier control  
• Asynchronous operation  
• Selectable data rates from 1200 to 57,600 bps  
• Distances to 2.4 miles  
• Point-to-point operation  
V.54 loopback tests and V.52 compliant BER tests  
• Six easy-to-read LED indicators  
• Transformer isolation  
3.1 FUNCTION CARD CONFIGURATION  
The Model 1018RC front card has two sets of eight switches (S1 &  
S2), which are mounted on the PC board (Figure 1, below). These  
configuration switches allow you to configure the Model 1018RC for a  
wide range of applications. The ON/OFF orientation of the DIP  
switches is shown in figure 2 (below). Jumpers JP1 through JP4 are  
primarily used for factory configuration, and should be left in their  
default positions.  
• Silicon Avalanche Diode surge protection  
• Switchable 120V or 240V power supply  
• Mounts in Patton’s 16-card rack chassis  
2.2 DESCRIPTION  
The Patton Model 1018RC short range modem rack card passes  
two “session” control signals (DTR/DCD), as well as two channel-  
independent flow control signals (RTS/CTS). This capability makes the  
Model 1018 suitable for SLIP (Serial Line Internet Protocol) and PPP  
(Point-to-Point Protocol) applications, as well as other serial  
applications requiring extra controls.

The Model 1018RC supports asynchronous data rates from 1.2 to  
57.6 Kbps, and distances to 2.4 miles. The Model 1018RC  
incorporates two V.54 test modes (local analog loop and remote digital  
loop), which can be activated from the front panel via the RS-232  
interface. Additionally, a built-in V.52 BER test generator can output  
511 and 511E bit patterns. Five easy-to-read LED indicators monitor  
power, transmit data, carrier detect, test mode and test pattern. For  
protection against ground loops and transient surges, the Model  
1018RC incorporates both isolation transformers and Silicon Avalanche  
Diode surge suppressors.

The Model 1018RC is designed to mount in Patton’s 2U high 19”  
rack chassis. This 16-card chassis has a switchable 120/240 VAC  
power supply (optional 48 VDC) and mounts cards in a mid-plane  
architecture: The front card can be plugged into different rear cards.  
This means that the Model 1018RC card can have several interface  
options and can be switched with other Patton short haul cards.

The eight DIP switches on pack S1 set Remote Test Activation and  
RTS/CTS Delay. Descriptions of all possible S1 switch settings,  
including the Patton factory default settings, are found on on pages 4  
and 5.  
The combined settings for switches S1-7 and S1-8 determine the  
amount of delay between the time the Model 1018RC “sees” RTS and  
when it sends CTS. Currently, the Model 1018RC does not have  
optional delay settings. “No Delay” is defined as between 500 nsec and  
1 msec. The switches should remain in the “OFF” position.

Line Shield & FRGND (JB2)  
This jumper affects the line interface. In the connected (closed)  
position, it links RJ-11 pins 1 & 6, or RJ-45 pins 2 & 7 to frame ground.  
These pins can be used as connections for the twisted pair cable shield.  
In the open (disconnected) position, pins 1 & 6 (or 2 & 7) remain  
connected to each other, but are “lifted” from the frame ground.  
Figure 6 (below) shows jumper locations for the four rear card  
options. These jumpers determine various grounding characteristics for  
the RS-232 and twisted pair lines.

4.0 INSTALLATION  
Switching the Power Supply On and Off  
This section describes the functions of the Model 1000R16 rack  
chassis, tells how to install front and rear Model 1018RC cards into the  
chassis, and provides diagrams for wiring the interface connections  
correctly.  
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 1000R16 is a “hot swappable” rack, it is not necessary 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.  
4.1 THE MODEL 1000R16 RACK CHASSIS  
The Model 1000R16 Rack Chassis (Figure 9) has sixteen short  
range modem card slots, plus its own power supply. Measuring only  
3.5” high, the Model 1000R16 is designed to occupy only 2U in a 19”  
rack. Sturdy front handles allow the Model 1000R16 to be extracted  
and transported conveniently.  
4.2 INSTALLING THE MODEL 1018RC INTO THE CHASSIS  
The Model 1018RC 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 1018RC 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.  
Figure 9. Model 1000R16 Rack Chassis with power supply  
4.1.1 THE RACK POWER SUPPLY  
5. Secure the front card using the thumb screws.  
The power supply included in the Model 1000R16 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.  
Note: Since the Model 1018RC16P chassis allows “hot swapping”  
of cards, it is not necessary to power down the rack when  
you install or remove a Model 1018RC.  
4.3 WIRING THE MODEL 1018RC  
Each of the rear interface cards compatible with the Model 1018RC  
has one terminal interface port and one 4-wire (twisted pair) port.  
These cards provide a female DB-25 for the terminal interface  
connection.  
WARNING! There are no user-serviceable parts in the power  
supply section of the Model 1018RC. Voltage setting changes and  
fuse replacement should only be performed by qualified service  
personnel. Contact Patton Electronics Technical support at  
more information.

4.3.1 TERMINAL INTERFACE CONNECTION  
Point-to-Point Twisted Pair Connection  
The RS-232 versions of the Model 1018RC use a DB-25 female to  
connect the terminal interface to your computing hardware. It is pinned  
according to the RS-232C/V.24 and EIA-530 interface standards. For  
specific interface pin-outs, please refer to the diagram in Appendix D of  
this manual.  
The 6-position RJ-11 and 8-position RJ-45 jack options for the  
Model 1018RC are prewired for a standard TELCO wiring environment.  
Connection of a 2-wire or 4-wire twisted pair circuit between two or  
more Model 1018RCs requires a crossover cable as shown in the  
following diagrams.  
RJ-11 Cable  
The EIA-561 versions of the Model 1018RC use a 10 pin RJ-45 to  
connect the terminal interface to your computing hardware. It is pinned  
according to the EIA-561 DCE interface standard. For specific interface  
pin-outs, please refer to the diagram in Appendix D of this manual.

4.3.2 TWISTED PAIR CONNECTION  
RJ-45 Cable  
The Model 1018RC operates over 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 1018RC can only  
communicate in a closed data circuit, and is compatible with the  
following Patton short hauls: Model 1018RC, Model 1018, Model  
1080A, Model 1080ARC. 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.

5.0 OPERATION  
4. If the BER test indicates no errors are present, move the V.52  
toggle switch to the right, thus activating the “511/E” test with  
periodic errors. If the test is working properly, the red “Error”  
LED will glow. A successful “511/E” test will confirm that the  
loop is in place, and that the Model 1018RC’s built-in “511”  
generator and detector are working properly.  
Once you have configured each Model 1018RC and connected the  
cables, you are ready to operate the units. Section 5.0 describes the  
power-up procedure and the built-in V.54 and V.52 test modes.  
5.1 POWER-UP  
5. If the BER test indicates that errors are present, check to see  
that the RS-232 cable connecting the DTE to the Model  
1018RC is wired straight through, and is plugged in properly.  
Also, ensure that the Model 1018RC is configured properly.  
Then re-check your DTE equipment. If you still have errors,  
call Patton Technical Support at (301) 975-1007.  
There is no power switch on the Model 1018RC: Power is  
automatically applied to the Model 1018RC 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 1018RC is a  
“hot swappable” card—it will not be damaged by plugging it in or  
removing it while the rack is powered up.  
5.2.2 REMOTE DIGITAL LOOPBACK (RDL)  
5.2 TEST MODES  
The Remote Digital Loopback (RDL) test checks the performance of  
both the local and remote Model 1018RCs, and the communication link  
between them. Any characters sent to the remote 1018RC 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  
1018RC and looped back. To perform an RDL test, follow these steps:  
The Model 1018RC 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.  
5.2.1 LOCAL ANALOG LOOPBACK (LAL)  
The Local Analog Loopback (LAL) test checks the operation of the  
local Model 1018RC, and is performed separately on each unit. Any  
data sent to the local Model 1018RC 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 RDL. This may be done in two ways: First, by  
moving the upper front panel toggle switch LEFT to “Remote”.  
Second, 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.  
1. Activate LAL. This may be done in one of two ways: First, by  
moving the upper front panel toggle switch RIGHT to “Analog”.  
Second, by raising pin 18 on the RS-232 interface (note: be  
sure DIP switch SW1-6 is enabled). Once LAL is activated,  
the Model 1018RC transmit output is connected to its own  
receiver. The Test” LED should be lit.  
3. Locate the lower of the two toggle switches on the front panel  
of the 1018RC and move it to the left. This will activate the  
V.52 BER test mode and inject a “511” test pattern 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 right, thus activating the “511/E” test  
with periodic errors. If the test is working properly, the red  
“Error” LED will glow. A successful “511/E” test will confirm  
that the loop is in place, and that the Model 1018RC’s built-in  
“511” generator and detector are working properly.  
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 1018RC and move it to the left. 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.

APPENDIX A  
5. If the remote BER test indicates that errors are present, and  
the local analog loopback/BER tests showed that both Model  
1018RCs 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 Support at (301) 975-1007.
