1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model 1080A Series 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 the shipment.

This warranty is l im ite d to defe cts in workmanship or materials, a nd doe s
not cover customer damage, abuse or unauthorized modification. If this
product fails or does not performs as warranted, your sole recourse shall
be repair or replacement as described above. Under no condition shall
Patton Electronics be liable for an y damage s incurr ed by the use of thi s
product. The se dama ges i nclud e, b ut are n ot lim ited to, t he fol lowing: lost
profits, lost savings and incidental or consequential damages arising
from the use of or inability to use this product. Patton Electronics spe

­cifically 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.

Note Conformity documents of all Patton products can be viewed

online at www.patton.com under the appropriate product page.

1.1 RADIO AND TV INTERFERENCE

The Model 1080A Series 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 recept ion . The Mode l 1080A Seri es has be en teste d and foun d
to comply with the limits for a Class A computing device in accordance
with specifications in Subpart B 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 1080A Series does
cause interference to radio or television reception, which can be deter

­mined 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 dif

­ferent AC outlet (such that the computing equipment and receiver are on
different branches).

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 European Union (EU). A Cer
tificate of Compliance is available by contacting Technical Support.

2.2 DESCRIPTION

The Model 1080A Series Universal Short Range Modem operates 2­wire (half duplex) or 4-wire (full or half duplex), in synchronous or asyn

­chronous modes, over unconditioned telephone lines. The Model 1080A
supports bit rates up to 57.6 kbps. The 1080A operates in synchronous
mode between the local and remote modems; when connected to an
asynchronous RS-232 device, the Model 1080A Series SRM converts
the asynchronous data to synchro nous data.

The Model 1080A Series has several features to enhance overall perfor­mance: automatic equalization, automatic gain control, anti-streaming
timer, transformer isolation to guard against data loss due to ground
potential differences, and Silicon Avalanche Diode surge protection to
guard against data line transients.

6

The Model 1080A Series features V.52 compliant bit error rate pattern
tests and two V.54 test modes: local analog loopback and remote digital
loopback. The operator at the local end may test both local and remote
modems, plus the line, in the digital loopback mode. Both RDL and LAL
modes can be controlled by a manual switch or via the V.24/RS-232
interface.

3.0 CONFIGURATION OVERVIEW

The Model 1080A Series is fairly 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 1080A properly.

3.1 CONFIGURATION SWITCHES

The Model 1080A Series uses a unique set of 24 external mini DIP
switches that allow configuration to an extremely wide range of applica

­tions. These 24 DIP switches are grouped into three eight-switch sets,
and are externally accessible from the underside of the unit (see
Figure 1). Since all configuration DIP switches are externally accessible,
there is no need to open the case for configuration.

The configuration switches allow you to select data rates, clocking meth­ods, V.52 & V.54 tests, word lengths, extended signaling rates, async. or
sync. mode, 2- or 4-wire operation, anti-stream control and input imped
ance. The drawings, text and tables on the following pages describe all
switch locations, positions and functions.

3.2 CONFIGURATION SWITCH SET “S1”

The DIP switches on S1 set data rate, clock source, async./sync. mode
and carrier control method. The default settings are summarized in
Table 1.
