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 shallPatton Electronicsbe 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 Electronicsspecifically 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 1040 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 1040 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 1040
does cause interference to radio or television reception, which can be
determined by disconnecting the RS-232 interface, 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).

1.3 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

telephone: [phone],

web address: http://www.patton.com;

email: [e-mail].

NOTE: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 1040. Technical Service hours: 8AM to 5PM EST, Monday

through Friday.

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU). A Certificate of Compliance is available by contacting Patton
Technical Support.

2.2 DESCRIPTION

The Model 1040carrier controlled short range modem supports

synchronous and asynchronous data rates to 38.4 Kbps. Requiring no
AC power or batteries, the Model 1040 supports distances to 12 miles
over unconditioned twisted pair. The Model 1040 features front panel
LEDs, automatic equalization, V.52 compliant BER tests, both internal
and external clocking and V.54 loopback tests. Built-in transformer
isolation and surge protection provide protection against ground
potential differences and AC/DC over-voltages.

The Model 1040 is simple to install and is ruggedly designed for
excellent reliability: just set it and forget it. The following instructions
will help you set up and install the Model 1040 properly. If you have
any questions, don’t hesitate to call Patton Electronics Technical
Support at [phone].

3.1 CONFIGURATION SWITCHES

The Model 1040 uses a unique set of sixteen external DIP
switches that allow configuration to an extremely wide range of
applications. These DIP switches are grouped into two eight-switch
sets and are externally accessible from the underside of the Model
1040 (see Figure 1). There is no need to open the Model 1040’s case
for configuration.

The configuration switches allow you to select data rates, clocking
methods, V.52 & V.54 tests, word lengths, extended signaling rates,
asynchronous or synchronous mode and 2- or 4-wire mode. The
drawings, text and tables on the following pages describe all switch
locations, positions and functions.

SW1

SW2

The Model 1040 is fully compatible with the Patton Model 1080A
and 1080ARC. This compatibility allows you to combine miniature,
standalone and rack mounted modems in a single system. In
synchronous mode, the Model 1040 is also compatible with the Models
1020, 1025 and 1030.

Housed in an ABS plastic case, the Model 1040 comes with either
a male or female DB-25 connector and a choice of interfaces (RJ-11
jack, RJ-45 jack or terminal blocks with strain relief).

3.2 CONFIGURATION SWITCH SETTINGS

SW1-1 through SW1-4: Data Rate Setting

The Model 1040 has two sets of eight switches, yielding 16 total
DIP switches. The two sets will be referred to as SW1 and SW2. As
Figure 2 shows, the orientation of all DIP switches is the same with
respect to “ON” and “OFF” positions.
