1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model 1015 components to be
free from defects, and will—at our option—repair or replace the prod­uct should it fail within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials,
and does not cover customer damage, abuse or unauthorized modifi­cation. If this product fails or does not perform as warranted, your sole
recourse shall be repair or replacement as described above. Under no
condition shall Patton Electronics be liable for any damages incurred
by the use of this product. These damages include, but are not limited
to, the following: lost profits, lost savings and incidental or consequen­tial damages arising from the use of or inability to use this product.
Patton Electronics specifically disclaims all other warranties,
expressed or implied, and the installation or use of this product shall
be deemed an acceptance of these terms by the user.

1.1 RADIO AND TV INTERFERENCE

The Model 1015 generates and uses radio frequency energy, and
if not installed and used properly—that is, in strict accordance with the
manufacturer’s instructions—may cause interference to radio and tele­vision reception. The Model 1015 has been tested and found to com­ply with the limits for a Class A computing device in accordance with
the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that interfer­ence will not occur in a particular installation. If the Model 1015 does
cause interference to radio or television reception, which can be deter­mined by turning the power off or disconnecting the modem, the user is
encouraged to try to correct the interference by one or more of the fol­lowing measures: moving the computing equipment away from the
receiver, re-orienting the receiving antenna and/or plugging the receiv­ing equipment into a different AC outlet (such that the computing
equipment and receiver are on different branches).

1.2 SERVICE

All warranty and non-warranty repairs must be returned freight
prepaid and insured to Patton Electronics. All returns must have a
Return Materials Authorization number on the outside of the shipping
container. This number may be obtained from Patton Electronics
Technical Service at [phone].

Packages received without an

RMA number will not be accepted.

Patton Electronics’ technical staff is also available to answer any
questions that might arise concerning the installation or use of your
Model 1015. Technical Service hours: 8AM to 5PM EST, Monday

through Friday.

2.2 DESCRIPTION

The Patton Model 1015 Miniature Short Range Modem provides

direct connection to DB-15 equipped RS-232 devices, such as the
Unisys (Sperry) 5000 and the NCR Tower series. Using the latest in
surface mount technology, the Model 1015 combines high quality per­formance and a miniature package. The Model 1015 requires no AC
power or batteries, supports distances to 17 miles and operates at data
rates to 19.2 Kbps. The Model 1015 is compatible with the Model
1000, 1005, 1006, 1009 and other Patton short range modems.

Measuring only 2.6” x 1.3” x .75”, the Model 1015 is housed in a
pop-open ABS plastic case. It is equipped with a male or female DB­15 connector and a choice of interfaces (RJ-11 jack, RJ-45 jack or ter­minal blocks with strain relief). In some models, an externally accessi­ble DCE/DTE switch allows easy connection to multiplexers and other
devices. The surge protected Model 1015S incorporates Silicon
Avalanche Diodes, which provide 600 watts peak per wire of protection
against harmful transient surges.

3.0 CONFIGURATION

The Model 1015 is designed to be easy to use. There are no
internal jumpers or configuration switches to set, so there is no need to
open the case to configure the unit (you may need to open the case for
wire connection—refer to section 4.0). However, in some models, you
may have to set the external DCE/DTE switch.

The figure below shows both versions of the Model 1015. If your
model looks like Figure 1, follow the instructions in Section 3.1. If your
Model 1015 looks like Figure 2, your unit will always operate in DCE
mode. Follow the instructions in Section 4.0.

3.1 SETTING THE DCE/DTE SWITCH

If your Model 1015 looks like Figure 1, it comes equipped with an
external DCE/DTE switch and requires special attention. If the device
connected to the Model 1015 is a modem or multiplexer (or is wired
like one), move the switch to “DTE”. This causes the Model 1015 to
behave like Data Terminal Equipment and transmit data on pin 1.

If the device connected to the Model 1015 is a PC, terminal or
host computer (or is wired like one), move the switch to “DCE”. This
setting causes the Model 1015 to behave like Data Communications
Equipment and transmit data on pin 9.

4.0 INSTALLATION

Once you have properly configured the DCE/DTE switch, you are
ready to connect the Model 1015 to your system. This section tells
you how to properly connect the Model 1015 to the twisted pair and
RS-232 interfaces, and how to operate the Model 1015.

4.1 CONNECTION TO THE TWISTED PAIR INTERFACE

The Model 1015 supports data-only communication between two
RS-232 devices at distances to 17 miles and data rates to 19.2 Kbps.
There are two essential requirements for installing the Model 1015:

1. These units work in pairs. Therefore, you must have one Model
1015 at each end of a two twisted pair interface.

2. To function properly, the Model 1015 needs two twisted pairs of
metallic wire. The pairs must be unconditioned, dry metallic wire,
between 19 and 26 AWG (the higher number gauges may limit
distance). Standard dial-up telephone circuits, or leased circuits
that run through signal equalization equipment are not acceptable.

For your convenience, the Model 1015 is available with three dif-

ferent twisted pair interfaces: RJ-11 jack, RJ-45 jack and terminal
blocks with strain relief.

4.1.1 TWISTED PAIR CONNECTION USING RJ-11 OR RJ-45

The RJ-11 and RJ-45 connectors on the Model 1015’s twisted pair

interface are pre-wired for a standard TELCO wiring environment (see
Figure 3). The table on the following page shows the signal/pin rela­tionships:
