3.1 STRAP LOCATIONS AND ORIENTATION  
The Model 1000RC Asynchronous Short Range Modem Rack  
Card is a dual rack card incorporating two short range modems. Both  
units operate full duplex at data rates to 19.2 Kbps over 2 twisted pairs  
and support distances to 17 miles. The Model 1000RC features 13  
easy-to-read front panel LEDs, which monitor the status of data  
transmission. The Model 1000RC also incorporates Silicon Avalanche  
Diodes for protection against the damaging effects of nearby lightning  
strikes and other harmful transients.  
The configuration straps on the Model 1000RC board allow you to  
configure the function of both “Carrier Detect” outputs. Figure 2 shows  
the orientation of these straps. Notice that each strap can either be on  
pegs 1 and 2, or on pegs 2 and 3.  
The Model 1000RC uses the latest surface mount technology to  
attain high quality short range modem performance in a convenient  
rack card. Filling one function card slot on Patton’s Model 1000R16P  
rack chassis, the Model 1000RC is available with RJ-11 or RJ-45 rear  
interface cards. For workgroup and desktop communications, the  
Model 1000RC also fits in Patton’s 2, 4 and 8 slot Cluster Boxes. The  
combination of rack mount, Cluster Box and self-powered units  
provides a completely integrated Model 1000 “networking” solution.

3.2 FRONT CARD CONFIGURATION  
3.3.1 REAR CARD STRAP SETTINGS  
The Model 1000RC contains two sets of configuration straps which  
allow you to set the function of “Carrier Detect” output. Since the Model  
1000RC contains two modems, each unit can be configured separately:  
Jumper 1 (JB1) controls Unit A, while Jumper 2 (JB2) controls Unit B.  
Figure 5 shows the strap locations for the 1Q11 and the 1Q45 rear  
cards. These straps determine various grounding characteristics for  
the RS-232 and twisted pair lines.

Each “Carrier Detect” strap can be set to “Normal” or “Always on”.  
When operating normally, the “CD” LED will blink to indicate the  
presence or absence of the carrier. When set to “Always on”, the “CD”  
LED will always indicate that the carrier is “ON”. Figure 3 (below)  
summarizes the switch settings.

This section describes the functions of the Model 1000R16P rack  
chassis, tells how to install front and rear Model 1000RC cards into the  
chassis and provides diagrams for wiring up the interface connections  
correctly.

Position 1&2 = Line B Shield Connected to Frame Ground  
Position 2&3 = No Shield  
4.1 THE MODEL 1000R16P RACK CHASSIS  
SGND & FRGND (JB5)  
The Model 1000R16P Rack Chassis (Figure 7) has sixteen short  
range modem card slots, plus its own power supply. Measuring only  
3.5” high, the Model 1000R16P is designed to occupy only 2U in a 19”  
rack. Sturdy front handles allow the Model 1000R16P to be extracted  
and transported conveniently.  
In position 1&2, this strap links signal ground and frame ground  
through a 100 Ohm, 1/2 W resistor. In position 2&3, pin 1 is “not  
connected to frame ground.  
JB5  
Position 1&2 = SGND and FRGND Connected  
Position 2&3 = SGND and FRGND Not Connected  
DTE as DSR or RI (JB6 & JB7)  
Because the Model 1000RC uses DSR (but not RI), only position  
1&2 is valid when this rear card is used with the Model 1000RC.  
Position 1&2 causes the terminal (DTE) to see DSR when the Model  
1000RC is powered up properly. Position 2&3 is for Ring Indicate,  
which is non-functional on the Model 1000RC. Furthermore, use of  
position 2&3 will cause DSR to float, which will lead to improper  
operation of the Model 1000RC.

JB6 & JB7  
4.1.1 THE RACK POWER SUPPLY  
Position 1&2 = DSR  
Position 2&3 = (Ring Indicate) Not Valid for Model 1000RC  
The power supply included in the Model 1000R16P 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.  
WARNING! There are no user-serviceable parts in the  
power supply section of the Model 1000RC. Voltage  
setting changes and fuse replacement should only be  
performed by qualified service personnel. Contact Patton  
Electronics Technical support at (301)975-1007 for more  
information.

Switching the Power Supply On and Off  
The Model 1000RC is wired as a DCE (Data Communications  
Equipment). Therefore, it wants to connect to a DTE (Data Termination  
Equipment). If your RS-232 output device is a DTE, you may need to  
use a special cable (such as a DB-25 to modular cable). If your  
RS-232 output device is DCE, you will require a null modem  
connection. Call Patton Technical Support at (301) 975-1007 for  
specific installation instructions.  
The power switch is located on the front panel. When plugged in  
and switched on, a red front panel LED will glow. Since the Model  
1000R16P 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.  
4.4 TWISTED PAIR CONNECTION  
4.2 INSTALLING THE MODEL 1000RC INTO THE CHASSIS  
The Model 1000RC operates full duplex 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  
are satisfactory. Note: The Model 1000RC can only be installed on  
private twisted pair cable. 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.  
The Model 1000RC 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 1000RC into the Model 1000R16P  
rack chassis:  
1. Slide the rear card into the back of the chassis along the metal  
rails.  
2. Secure the rear card using the metal screws provided.  
Notice! Any modular twisted pair cable connected to  
the Model 1000RC must be shielded cable, and the outer  
shield must be properly terminated to a shielded modular  
plug on both ends of the cable.  
3. Slide the front 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.  
4.4.1 POINT-TO-POINT TWISTED PAIR CONNECTION  
5. Secure the front card using the thumb screws.  
The 6-position RJ-11 and 8-position RJ-45 jack options for the  
Model 1000RC–always the upper jack on the rear interface card–are  
prewired for a standard TELCO wiring environment (See Appendix D  
for pin number orientations). Connection of a 4-wire twisted pair circuit  
between two or more Model 1000RCs requires a crossover cable as  
shown in the following charts.  
Note: Since the Model 1000R16P chassis allows “hot swapping”  
of cards, it is not necessary to power down the rack when you  
install or remove a Model 1000RC.  
4.3 RS-232 CONNECTION  
RJ-11 Cable  
The RS-232 ports are always the lower ports on the interface card.  
The 10-pin RJ-45 is pinned according Patton's Modified Modular  
Interface Standard (based on the EIA/TIA-561Standard). For specific  
interface pin-outs, please refer to the diagrams in Appendix D.

• The green “PWR” LED glows when power is being applied to the  
modem card through its mid-plane chassis connection.  
• The “TD” and “RD” indicators blink red and green to show data  
activity. A solid red light indicates an idle state. Solid green is an  
“illegal” condition and typically indicates a problem in the system.  
• If your carrier detect strap is configured as “Always On”, the “CD”  
light will always be green. If the carrier detect strap is set to  
“Normal”, the green LED lights when the receive carrier is detected;  
the red LED lights when the receive carrier is absent.  
5.2 POWER-UP  
There is no power switch on the Model 1000RC: Power is  
automatically applied to the 1000RC when its card-edge connector  
touches the chassis’ mid-plane socket, or when the chassis’ power is  
turned on. Note: The 1000RC is a “hot swappable” card—it will not be  
damaged by plugging it in or removing it while the rack is powered up.
