1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model 1010A 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 1010A 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 1010A 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
1010A 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).

1.2 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 1010A. Technical Service hours: 8AM to 5PM EST, Monday

through Friday.

2.1 FEATURES

• Transformer coupled for DC isolation between modems

• Immune to ground loops caused by ground potential differences

• Supports asynchronous RS-232 communication over 2 twisted pair

• Supports data rates to 115.2 Kbps, distances to 8.5 miles

• Loops back all handshaking signals on the RS-232 interface

• Externally accessible DCE/DTE switch makes configuration easy

• Very thin case (.75") for closely spaced computer ports

• No AC power or batteries required—draws all necessary operating
power from the RS-232 interface

• Provides surge protection of 600 Watts per wire

RS-232C PIN CONFIGURATIONS

APPENDIX C

2.2 DESCRIPTION

The Patton Model 1010A miniature, high speed, transformer

isolated short range modem lets two asynchronous RS-232 devices

communicate between buildings, over two twisted pair. Supporting
asynchronous data rates to 115.2 Kbps, the Model 1010A derives the
necessary power for operation from the data and control voltages on
the RS-232 interface. DC transformer isolation on the line side gives
the Model 1010A immunity to ground loops that would otherwise
hamper between-building communications.

An external DCE/DTE switch lets you connect to the serial port of

either a computer/terminal (DTE) or a modem (DCE) without using a
crossover cable. The Model 1010A is available with three 4 wire
interface options: RJ-11, RJ-45 or terminal blocks with strain relief.

The Model 1010A also incorporates high speed avalanche diodes

that intercept data line transient surges and shunt them safely to
chassis ground. With surge handling capacity of 600W per wire at
1mS, the 1010A can protect itself and connected equipment from
nearby lightning strikes and other surges of electromagnetic radiation.
