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. Tri­state 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.
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.

3.0 CONFIGURATION
The Model 1060 features externally accessible configuration switches, located on the underside of the unit; there is no need to open the case to configure the Model 1060. Figure 1 (below) shows the location of the DIP switch set, as well as the two DCE/DTE switches.
Figure 1. Switch locations underneath Model 1060
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:

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.
Control Output (C
out
):
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.
+Voltage Output (+V
out
):
The +Voltage Output signal is a constant positive voltage that is sent from the 1060 to its attached DTE device.
Carrier Controlled by (C
in
):
When Carrier Controlled by Control Input is “Enabled”, the Model 1060’s transmitter is activated by the corresponding C
in
Signal from the
DTE. In effect, the Control Input signal on the local 1060 "controls" the 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”.

3.1.2 MULTIPOINT CONFIGURATION
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".
3.3 SPECIAL CONFIGURATION
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.
*Multiple input pins are "or-tied"—if any input goes low, carrier is dropped
**Multiple output pins generate the same signal simultaneously

4.1 TWISTED PAIR WIRING OVERVIEW
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:
4.1.1 TWISTED PAIR CONNECTION USING TERMINAL BLOCKS
If your two twisted pair line terminates in bare wires, strip the ends and connect the individual leads to each Model 1060's terminal block. Be sure the end-to-end connections follow the diagram above.
4.1.2 TWISTED PAIR CONNECTION USING RJ-11
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.

4.2 WIRING FOR MULTIPOINT CIRCUITS
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.
4.2.1 DAISY CHAIN TOPOLOGY
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.
Figure 3 (below) shows how to wire the two-pair cables properly for a Model 1060 daisy chain topology. Note that the ground connection is not needed.
In a multipoint topology, you must configure the master Model 1060's DIP switches differently than those of the slave Model 1060(s). Here are the proper DIP switch settings for a daisy chain topology:
Switch
Number 1 2 3 4 5 6 7 Master Positions ON ON ON OFF OFF OFF OFF Slave Positions ON ON ON OFF OFF OFF ON
4.2.2 STAR TOPOLOGY
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.
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.
In a multipoint topology, you must configure the master Model 1060's DIP switches differently than those of the slave Model 1060(s). Here are the proper DIP switch settings for a star topology:
Switch
Number 1 2 3 4 5 6 7 Master Positions ON ON ON OFF OFF OFF OFF Slave Positions ON ON ON OFF OFF OFF ON
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.

5.2.2 REMOTE ANALOG LOOP
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.

5.0 OPERATION
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.
5.1 LED INDICATORS
The Model 1060 incorporates six front panel LEDs that show the status of the modem:
1. The power LED glows when AC power is applied to the modem.
2. The loopback test LED glows when the loopback test switch
has been depressed and is in a test mode.
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.
4. The control in and control out indicators glow red for a "low" signal and green for a "high" signal. The specific pin number associated with these indicators will vary according to the switch settings you have selected (see Section 3.0 Configuration).
5.2 LOOPBACK TEST MODES
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).

APPENDIX B
PATTON MODEL 1060 CABLE RECOMMENDATIONS
The Patton Model 1060 is designed and tested to communicate
over twisted-pair cable with the following characteristics:
Wire Gauge Capacitance Resistance
19 AWG 83nF/mi or 15.72 pF/ft. .0163/ft. 22 AWG 83nF/mi or 15.72 pF/ft. .0326/ft. 24 AWG 83nF/mi or 15.72 pF/ft. .05165/ft.
Using the above characteristics as a baseline, we estimate the
distance limitations for the Model 1060 to be as follows.
To reduce the potential of difficulties in the field, we recommend that the cable used to connect the Model 1060s have a capacitance of no greater than 20pF/ft., and that the wire be no thinner than 26 AWG. The Model 1060 is designed to withstand normal environmental noise and conditions. However, other environmental factors too numerous to discuss may affect proper operation.
The distance table above should
be used as a general guideline only.
