3.0 CONFIGURATION  
To change the DTE/DCE setting, do the following:  
By default, the Model 1012B is configured to be a DCE with the  
transmitter set for controlled carrier. If the 1012B is in controlled carrier  
mode for multi-point operation, the transmitter is controlled by RTS (pin 4)  
when it is a DCE, and controlled by CD (pin 8) when configured as a DTE.  
1. Using a small screwdriver, insert the tip into one of the slots in  
the side of the Model 1012B (see Figure 2).  
The DTE/DCE slide switch (SW1 in Figure 1) is used to configure  
DTE or DCE orientation. The RTS/CD control jumper (J2 in Figure 1) is  
used to configure constant/controlled carrier mode.  
Section 3.1 describes how to configure the DTE/DCE switch.  
Section 3.2 provides information on configuring the transmitter to be  
constant or controlled.  
3.1 SETTING THE MODEL 1012B AS DCE OR DTE  
Note: Remember that when the DTE/DCE switch is set for DCE,  
the 1012B functions as a DCE device. Otherwise, when the switch is in  
the DTE position, the short range modem operates as a DTE device..  
SW1 (located inside the Model 1012B) controls the DTE/DCE  
configuration of the Model 1012B. Figure 1 shows the location of the  
DTE/DCE switch on the 1012B circuit board.

DTE

3. If the device connected to the Model 1012B is a PC, terminal  
or host computer (or is wired like one), set switch SW1 to “DCE” (see  
Figure 3). This causes the Model 1012B to behave like data  
communications equipment.  
4. If the device connected to the Model 1012B is a modem or  
multiplexer (or is wired like one), set the switch to “DTE.” This setting  
causes the Model 1012B to behave like data terminal equipment.  
5. After you finish configuring the DTE/DCE switch, snap the  
case halves back together, then go to section 4.0, “Installation.”

3.2 SETTING THE RTS/CD CARRIER CONTROL JUMPER  
4.0 INSTALLATION  
The RTS/CD jumper (see Figure 1) is identified as J2 inside the  
1012B (see Figure 1). To access this strap, do the following:  
Once you have properly configured the Model 1012B, you are  
ready to connect it to your system. This section tells you how to  
connect the Model 1012B to the twisted pair and RS-232 interfaces,  
and how to operate the Model 1012B.  
1. Using a small screwdriver, insert the tip into one of the slots in  
the side of the Model 1012B (see Figure 2).  
2. Rotate the screwdriver as shown in Figure 2 to open the case.  
4.1 HOW TO CONNECT TO THE TWISTED PAIR INTERFACE  
The Model 1012B passes data and handshaking signals between  
two RS-232 devices at distances to 6 miles (9.7 km) and data rates to  
38.4 kbps. There are two requirements for installing the Model 1012B.

1. These units work in pairs. Therefore, you must have one Model  
1012B at each end of a two twisted pair interfaces.

Table 1. Interaction of DTE/DCE switch and RTS/CD strap  
2. To function properly, the Model 1012B needs two twisted pair of  
metallic wire. They must be unconditioned, dry metallic wire,  
unloaded, between AWG 19 and 26 (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.  
3. The RTS/CD carrier control jumper setting on the 1012B  
determines whether the transmitter is constantly on or is controlled by an  
RS-232 control signal. When this jumper is removed from the pegs, the  
1012B transmitter is constantly on. When the jumper is in place on the  
pegs, the transmitter is controlled by either RTS or CD. When the control  
signal is a positive voltage, the transmitter is turned on, if negative  
voltage, the transmitter is off. See Table 1 for the correspondence  
between DTE/DCE and RTS/CD parameters.  
For your convenience, the Model 1012B is available with the  
following twisted pair interfaces: RJ-11 jack, RJ-45 jack, and terminal  
blocks.

Carrier Detect Function  
Carrier detect is output  
on pin 8 (CD)  
Carrier detect is output  
on pin 4 (RTS)  
If your application requires you to connect one or two pair of bare  
wires to the Model 1012B, you will need to access the external terminal  
blocks. The following instructions will tell you how to connect the bare  
wires to the terminal blocks.  
Table 2. Interaction of DTE/DCE switch and RTS/CD jumper  
4. The RTS/CD carrier control jumper also controls which signal  
will function as the Carrier Detect (CD) signal. If the DTE/DCE switch is  
set to “DCE,” the carrier detect is output on Pin 8. If the DTE/DCE  
switch is set to “DTE,” the carrier detect is output on Pin 4. Table 2  
shows which control signal provides the carrier detect function, per the  
DTE/DCE setting.  
1. Strip the outer insulation from the twisted pairs about one inch  
from the end.  
2. Strip the insulation on each of the twisted pair wires about  
0.25 inch.  
Note: For multi-point applications, it is necessary to have a jumper  
in place on the pegs on the slave modems.  
5. After you finish configuring the DTE/DCE switch, snap the  
case halves back together and continue the installation process.

Signal/Pin Assignments  
The 6-wire RJ-11 and 8-wire RJ-45 jack options for the Model  
1012B are prewired for a standard TELCO wiring environment. Use the  
guide below when ordering or constructing twisted pair cables.

3. Connect one pair of wires to XMT+ and XMT- (transmit positive  
and negative) on the terminal block, making careful note of  
which color is positive, and which color is negative.

4.1.2 MODULAR TWISTED PAIR CONNECTION  
The Model 1012B offers two interface options for twisted pair  
connection: RJ-11 (6-wire) jack and RJ-45 (8-wire) jack. Pages 9 and  
10 show signal/pin assignments for the jacks, as well as pin-outs for the  
appropriate twisted pair cable topologies.

Using a daisy chain topology, you may connect several Model  
1012Bs together in a master/slave arrangement. Maximum distance  
between the units will vary based upon the number of drops, data rate,  
wire gauge, etc. Contact Patton Technical Support at (301) 975-1007;

The Model 1012B supports multi-point applications using either a  
star or a daisy chain topology. Both topologies require special wiring.  
Note: Refer to Section 3.2 for multi-point settings.

Model 1012B’s daisy chain topology. Note that the ground connection is  
not needed.  
4.2.1 STAR TOPOLOGY  
Using a star topology, you may connect several Model 1012Bs  
together in a master/slave arrangement. Maximum distance between  
the units will vary based upon the number of drops, data rate, wire  
gauge, etc. Contact Patton Technical Support (301) 975-1007;  
distance estimates.  
Optional Connection: Dual Modular Jacks  
To facilitate daisy chaining, the Model 1012B is available in a  
"DRJ11" (dual RJ-11) or "DRJ45" (dual RJ-45) version. These units have  
two specially wired modular jacks for twisted pair connection. With the  
dual modular units, you do not need to build cumbersome "Y" cables for  
your daisy chain application. Simply use a crossover cable to go between  
the host and the first slave (see Section 4.1.2 for crossover cable wiring  
instructions), and straight through cables between the slaves.  
Table 3 shows how to wire the two-pair cables properly for a Model  
1012B star topology. Note that the ground connection is not needed.

4.3 CONNECTION TO THE RS-232 INTERFACE  
Once you have properly configured the Model 1012B and  
connected the twisted pair wires correctly, plug the Model 1012B  
directly into the DB-25 port of the RS-232 device. After doing so,  
remember to insert and tighten the two captive connector screws.

Note: If you must use a cable to connect the Model 1012B to the

the shortest possible length—we recommend 6 feet (1.8  
meters) or less.

4.4 OPERATING THE MODEL 1012B  
Once the Model 1012B is properly 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. Additionally, one control signal is passed in each direction.
