2.2 DESCRIPTION
The Model 1060 Series asynchronous short range modem is
equipped with a virtual wish list of “bells and whistles”: Point-to-point or
multipoint applications are supported. Two separate control signals
may be passed (one each way), each with switch-selectable pin
assignments. Data lines are protected from ground loops and
electrically volatile environments by optical isolation and Silicon
Avalanche Diodes. System integrity can be evaluated using two built-in
test modes: local analog loopback and remote analog loopback. Tri-
state LEDs monitor transmit data, receive data and control signals.
Finally, 4-wire connections may be made using either RJ-11 jack or
terminal blocks—both are included.
3.1 "QUICK SET-UP" INSTRUCTIONS
In the majority of applications, you won't need an in-depth
knowledge of the Model 1060's capabilities to get up and running. The
following "quick set-up" DIP switch configurations cover most Model
1060 operating environments. (Note: DIP switch 8 not used)
3.1.1 POINT-TO-POINT CONFIGURATION
If you are installing these units in a point-to-point application with a
computer, printer or terminal, configure the DIP switches on both Model
1060s as follows:
In addition, the Model 1060 is perfect for low power RS-232
environments. The new Model 1060 is AC powered, and therefore is
the recommended solution for RS-232 environments whose interface
voltages are below RS-232 specifications. The Model 1060 supports
data rates to 115.2 Kbps and extends RS-232 transmission distances
up to 14 miles over two twisted pair.

The Model 1060 is housed in a sturdy metal case and comes with
either 115 or 220V external transformers. This is the top-of-the-line in
asynchronous short range modems.

3.1.2 MULTIPOINT CONFIGURATION
Control Input (Cin):
The Control Input signal is used by the local Model 1060 as an
input signal to activate its transmitter (“Enabled” settings) and allow
data transmission to the remote device. This is required for half-duplex/
switched-carrier environments as well as in hardware flow control
applications. In the “Disabled” settings, the 1060 is always “turned on”
and sends a continuous carrier to the remote 1060.
The Model 1060 supports multipoint operation in either daisy chain
or star configurations. For multipoint configuration and wiring
information, refer to Section 4.2, pages 7.
3.2 DCE/DTE SWITCH SETTINGS
Correct setting of the DCE/DTE switches eliminates the need for
RS-232 crossover cables. If the RS-232 device you are connecting to
the Model 1060 is a PC, terminal or host, or is wired like one, set both
of the DCE/DTE switches to "DCE". If the RS-232 device you are
connecting to the Model 1060 is a modem or multiplexer, or is wired like
one, set both of the DCE/DTE switches to "DTE".
Control Output (Cout):
The Control Output signal is transmitted by the local Model 1060
to its attached DTE device. This signal should be the same logic state
as the Control Input signal on the remote 1060. This signal is required
in half-duplex/switched carrier environments or in hardware flow control
applications.
3.3 SPECIAL CONFIGURATION
+Voltage Output (+Vout):
If your installation requires special configuration of the Model 1060,
use Table 1 (below) as a guide. This table shows all of the possible
Model 1060 switch settings. Following the table are brief descriptions
of the Control Input, Control Output, +Voltage Output and Carrier
Controlled by (Cin) parameters shown in the table below.
The +Voltage Output signal is a constant positive voltage that is
sent from the 1060 to its attached DTE device.

presence of "carrier" and the Control Output signal on the remote 1060.
This setting is required in half-duplex/switched carrier environments or
in hardware flow control applications. When Carrier Control by Control
Input is “Disabled”, the 1060 sends a continuous carrier and is always
“turned on”.

4.0 INSTALLATION
4.1.2 TWISTED PAIR CONNECTION USING RJ-11
The Model 1060 is easy to install. After configuring the DIP
switches and DCE/DTE switches, connect the two twisted pairs using
one of two methods: terminal blocks or RJ-11 jack. Figure 2 (below)
shows the location of the terminal blocks and RJ-11 jack, as well as the
female DB-25, on the rear of the Model 1060.
If your two-pair cable is terminated in an RJ-11 plug, you may use
the RJ-11 jack in the back of the Model 1060 to make the connection.
The RJ-11 jack on a Model 1060 series Short Range Modem is
prewired for a standard TELCO wiring environment. To be sure you
have the right wiring, use the diagram below as a guide.

These short range modems are designed to work in pairs. You will
need one at each end of a 4-wire twisted pair circuit. The pairs must be
"dry" (unconditioned) metallic wire, 19 - 26 AWG. The smaller gauges
limit distance somewhat compared with larger gauges. When you have
completed wiring for your data circuit, the pin connections should be as
shown below:

4.2 WIRING FOR MULTIPOINT CIRCUITS
4.2.2 STAR TOPOLOGY
The Model 1060 supports multi-point applications using either a
star or daisy chain topology. Both topologies require special wiring, as
well as specific DIP switch settings for master and slave units.
Using a star topology, you may connect several Model 1060s
together in a master/slave arrangement. Maximum distance between
the units will vary based upon the number of drops, data rate, wire
gauge, etc. Call Patton Technical Support for specific distance
estimates.
4.2.1 DAISY CHAIN TOPOLOGY
Figure 4 (below) shows how to wire the two-pair cables properly for
a Model 1060 star topology. Note that the ground connection is not
needed.
Using a daisy chain topology, you may connect as many as 10
Model 1060s together in a master/slave arrangement. Maximum
distance between the units will vary based upon the number of drops,
data rate, wire gauge, etc. Call Patton Technical Support for specific
distance estimates.

4.3 RS-232 CONNECTION
To connect the Model 1060 to a piece of data terminal or data
communications hardware, use a straight through RS-232 cable. Plug
the cable directly into the DB-25 port on the rear of the Model 1060.
The DCE/DTE switches eliminate the need for a crossover cable.

5.0 OPERATION
5.2.2 REMOTE ANALOG LOOP
Once you have configured each Model 1060 properly and
connected it, simply plug in the AC power adapter to get it running;
there is no power switch on the Model 1060. You can monitor the
operation of the Model 1060 using the front panel LED indicators and
built-in loopback test modes.
The second test mode is Remote Analog Loop. To enter this
mode, set one of the Model 1060s (local) in test mode by depressing
the "Loopback Test" switch. Any characters sent from the remote 1060
will be returned to it (see Figure 5). If no characters are echoed back,
check the wiring between the two Model 1060s. Be sure to wire the
units according to the instructions in Section 4.0 Installation.
5.1 LED INDICATORS
The Model 1060 incorporates six front panel LEDs that show the
status of the modem:
TX+

3. The tri-state TD and RD indicators blink red and green with data
activity. Solid red indicates a low RS-232 logic level and no color
indicates no activity on the line. Note: RS-232 devices idle in a low
state, so the LED will glow red if the connections are correct and the
RS-232 device is in an idle state.

Select the test modes by depressing the "Loopback Test" switch.
When in loopback mode, the "Loopback Test" LED will glow red. Two
tests are possible using this switch: Local Analog Loop (LAL), and
Remote Analog Loop (RAL).
5.2.1 LOCAL ANALOG LOOP
The first test mode is Local Analog Loop (V.54 Loop 3). Any data
sent to the local Model 1060 in this 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 (see Figure 5
on the following page).
