1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model 1010B 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 1010B 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 1010B 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
1010B 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 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 Technical
Support.

2.0 GENERAL INFORMATION

Thank you for your purchase of this Patton Electronics product.
This product has been thoroughly inspected and tested and is
warranted for One Year parts and labor. If any questions arise during
installation or use of the unit, contact Patton Electronics Technical
Support [phone].

2.1 FEATURES

• Transformer coupled for DC isolation between modems

• Immune to ground loops caused by ground potential differences

• Distances to 9.5 miles over 2 twisted pair (19 AWG@ 1200 bps)

• Supports data rates from 300 bps to 115.2 kbps

• 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

2.2 DESCRIPTION

The Patton Model 1010B 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 1010B 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 1010B 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 1010B is available with three 4 wire
interface options: RJ-11, RJ-45 or terminal blocks with strain relief.

3.0 CONFIGURATION

The Model 1010B 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 1010B can protect itself and connected equipment from
nearby lightning strikes and other surges of electromagnetic radiation.

The Model 1010B is configured using an external DCE/DTE switch
and two internal jumpers (the factory jumper settings are appropriate for
most applications). This section describes the configuration switch and
jumpers and shows factory defaults. Figure 1 below shows the location
of the switch/jumpers on the Model 1010B’s internal PC board.

3.1 SETTING THE DTE/DCE SWITCH

For your convenience, the Model 1010B has an externally
accessible DCE/DTE switch (see Figure 2, below). If the device
connected to the Model 1010B is a modem or multiplexer (or is wired
like one), set the switch to "DTE." This setting causes the Model 1010B
to behave like Data Terminal Equipment and transmit data on pin 2.

If the device connected to the Model 1010B is a PC, terminal or
host computer (or is wired like one), set the switch to "DCE." This
setting causes the Model 1010B to behave like Data Communications
Equipment and transmit data on pin 3.
