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 limited to defects in workmanship or materials, and does

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 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 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 reception. The Model 1080A Series has been tested and found

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.

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 Materi-

als Authorization number on the outside of the shipping container. This

number may be obtained from Patton Electronics Technical Services at:

•Tel:+1 (301) 975-1007

2.2 DESCRIPTION

The Model 1080A Series Universal Short Range Modem operates 2-

wire (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 synchronous data.

The Model 1080A Series has several features to enhance overall perfor-

mance: 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.

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 meth-

ods, 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.

Each Model 1080A Series SRM has three sets of eight switches, yielding

24 total DIP switches. The three sets will be referred to as S1, S2 and

S3. As Figure 2 shows, the orientation of all DIP switches is the same

with respect to “ON” and “OFF” positions.

Figure 2. Close-up of DIP switches showing “ON” and “OFF” positions

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.

Switches S1-1 through S1-4: Data Rate Setting

Switches S1-1 through S1-4 are set in combination to determine the

asynchronous and synchronous data rate for the Model 1080A.

Switches S1-5 and S1-6: Clock Source

Switches S1-5 and S1-6 are set in combination to determine the transmit

clock source for the Model 1080A Series.

Switch S1-7: Asynchronous/Synchronous Mode

The setting for switch S1-7 determines whether the Model 1080A Series

is in asynchronous or synchronous operating mode.

Switch S1-8: Carrier Control Method

The setting for switch S1-8 determines whether the carrier is “constantly

on” or “controlled by RTS”. This setting allows for operation in switched

carrier, multipoint and/or hardware handshaking applications.

3.3 CONFIGURATION SWITCH SET “S2”

The DIP switches on S2 set word length, extended signaling rate,

RTS/CTS delay, V.52 and V.54 diagnostic test and 2- and 4-wire opera-

tion.
