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 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 1030 provides seven configuration switches, which  
allow selection of carrier control method, clocking method, RTS/CTS  
delay and data rate. This section describes switch locations and  
explains all possible switch configurations.  
3.1 SWITCH LOCATIONS  
2.1 FEATURES  
For your convenience, all configuration switches are located on a  
SIP (single in-line package) mounted on the PC board. Figure 1 shows  
the location of the SIP with respect to other PC board components. For  
instructions on opening the Model 1030 case, see Section 4.1.2.

2.2 DESCRIPTION  
The Patton Electronics Model 1030 synchronous, multipoint  
short range modem provides exceptional versatility in a compact  
package. Measuring only 2.66” x 2.10” x and 0.73”, the Model 1030 is  
suitable for many applications where connection space is limited. The  
Model 1030 supports up to twelve drops, and requires no AC power or  
batteries for operation.

Operating at switch selectable data rates between 1.2 and 19.2  
Kbps, the Model 1030 can attain distances between 3.5 and 8.5 miles  
over two 24 AWG twisted pair (thicker gauges may yield better  
distances). The Model 1030 operates half duplex or full duplex, and  
accommodates three clocking methods: internal, external and received  
loopback. Transformer isolation guards the Model 1030 against  
ground looping in building-to-building applications. Other features  
include a selectable RTS/CTS delay of 7 mSec or 53 mSec, and  
selectable carrier status of constantly on or RTS controlled.  
Figure 2 shows the orientation of the switches on the SIP, including  
ON/OFF position.

3.2 SWITCH SETTINGS  
Switch 5: RTS/CTS Delay  
All possible settings for the Model 1030’s configuration switches  
are presented in the summary table and descriptions below. If you  
have additional questions regarding configuration, contact Patton  
Technical Support at (301) 975-1007.  
After request to send (RTS) is raised by the host terminal, the  
Model 1030 raises CTS after a slight delay in order to give the remote  
terminal time to receive an incoming signal. Depending on the type of  
environment, either a 7mS or 53mS delay can be selected.

Switch 2 is used to specify how the carrier signal is raised. In most  
point-to-point, full duplex applications, the carrier signal can remain  
constantly “high”. In a multi-point environment, contention for the line is  
“controlled” by RTS.

4.0 INSTALLATION  
When connecting two Model 1030s, it is necessary to use a  
“crossover” cable. The diagram below shows how a crossover cable  
should be constructed for an environment where both Model 1030s use  
a 6-wire RJ-11 connector. Similar logic should be followed when using  
RJ-45 connectors or a combination of the two.  
Once the Model 1030 is properly configured, it is ready to connect  
to your system. This section tells you how to properly connect the  
Model 1030 to the twisted pair and RS-232 interfaces, and how to  
operate the Model 1030.

The Model 1030 supports data-only communication between two  
RS-232 devices at distances to 11 miles and data rates to 19.2 Kbps.  
There are two essential requirements for installing the Model 1030:  
1. These units work in pairs. Therefore, you must have one Model  
1030 at each end of a two twisted pair interface.  
Connection to ground is optional  
2. To function properly, the Model 1030 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.

4.1.1 TWISTED PAIR CONNECTION USING RJ-11 OR RJ-45  
The RJ-11 and RJ-45 connectors on the Model 1030’s twisted pair  
interface are pre-wired for a standard TELCO wiring environment. The  
signal/pin relationships are shown below:  
4.1.2 TWISTED PAIR CONNECTION USING TERMINAL BLOCKS  
If your application requires you to connect two pair of bare wires to  
the Model 1030, you will need to open the case to access the 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.

1. Open the unit by gently inserting a screwdriver between the  
DB-25 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.  
4. Connect one pair of wires to the two XMT (transmit) poles on  
the terminal block. The Model 1030 is not polarity sensitive,  
so either wire may connect to either pole.  
5. Connect the other pair of wires to the two RCV (receive) poles  
on the terminal block. The Model 1030 is not polarity  
sensitive, so either wire may connect to either pole.  
Ultimately, you will want to construct a two pair crossover  
cable that makes a connection with the two Model 1030s as  
shown below:

To Shield (Optional)  
6. If there is a shield around the telephone cable it may be  
connected to “G” on the terminal block. To avoid ground  
loops, we recommend connecting the shield at the computer  
end only. A ground wire is not necessary for proper operation  
of the Model 1030.  
Once the unit has been opened, you will be able to see the  
terminal blocks located at the rear of the PC board.  
7. When you finish connecting the wires to the terminal block, the  
assembly should resemble the diagram below:  
2. Strip the outer insulation from the twisted pairs about one inch  
from the end.  
3. Strip back the insulation on each of the 2 twisted pair wires  
about .25”.

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.  
10. Place the top half of the case as necessary to slide it over the  
strain relief assembly. Do not snap the case together yet.  
11. Insert one captive screw through a saddle washer. Then insert  
the entire piece 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 cable installation.  
4.2 CONNECTION TO THE RS-232 INTERFACE  
9. Insert the strain relief assembly and wire into the slot in the  
bottom half of the modem case and set it into the recess in the  
case.  
Once you have connected the twisted pair wires correctly, simply  
plug the Model 1030 directly into the DB-25 port of the RS-232 device.  
After doing so, remember to insert and tighten the two captive  
connector screws.  
4.2.1 CONNECTION TO A “DTE” DEVICE  
The Model 1030 is wired as a DCE, and therefore wants to plug  
into a DTE such as a terminal, PC or host. Because the Model 1030 is  
interface powered, a direct connection to the RS-232 DTE port is most  
desirable. If you must use a cable to connect the Model 1030 to the  
DTE port, make sure it is a straight through cable of the shortest  
possible length—we recommend 6 feet or less.

4.2.2 CONNECTION TO A “DCE” DEVICE  
PATTON MODEL 1030/1030S SPECIFICATIONS  
Since the Model 1030 is wired as a DCE, you cannot connect it  
directly to another DCE such as a modem, multiplexer or printer. If you  
need to connect the Model 1030 to another DCE device, you must use  
a null modem cable wired according to diagram below. We recommend  
that you use the shortest possible cable, preferably 6 feet or less.

4.3 OPERATING THE MODEL 1030  
Once the Model 1030 is properly configured and 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 signals from the RS-232 interface  
are passed straight through. In addition, one hardware control signal is  
passed in either direction.
