1.1 RADIO AND TV INTERFERENCE

The Model 1002 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 1002 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 1002
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 nonwarranty 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

2.2 DESCRIPTION

The Model 1002 Asynchronous Short Range Modemextends
RS-232 distances to 2 miles (3.2 km) over coax or a single
unconditioned twisted pair. The small size of this unit enables use
where serial ports are very close together or are not easily accessible.
The Model 1002 incorporates innovative circuitry that lets it operate
without connection to AC power or batteries. The necessary power for
operation is derived from the RS-232 input signals.

An external DCE/DTE switch allows easy connection of the Model
1002 to any device without opening the unit to re-configure. Three
enclosure options allow termination of a single twisted pair via RJ-11,
RJ-45 or terminal blocks. A unique strain relief prevents the twisted
pair from breaking or pulling loose. An additional enclosure option
allows termination of coax cable via female BNC.

The Patton Model 1002 is easy to install and should give you
years of trouble-free service. You must have a PAIR of units to perform
an installation—one at each end of an unconditioned twisted pair or
coax cable. The following instructions explain this procedure.

3.1 SETTING THE DTE/DCE SWITCH

For your convenience, the Model 1002 has an externally
accessible DCE/DTE switch (see diagram below). If the device
connected to the Model 1002 is a modem or multiplexer (or is wired like
one), set the DCE/DTE switch to “DTE”. This means the Model 1002
will behave like Data Terminal Equipment and transmit data on pin 2.

If the device connected to the Model 1002 is a PC, terminal or host
computer (or is wired like one), set the DCE/DTE switch to "DCE". This
setting means the Model 1002 will behave like Data Communications
Equipment and transmit data on pin 3.

3.2 CONNECTING THE LINE SIDE

Depending upon the type of unit, the Model 1002 connects to the
line side via single twisted pair (terminal block, RJ-11, RJ-45) or coax
(BNC). Follow the appropriate instruction set for the type of unit you
have.

3.2.1 Connection Using the Terminal Block

DTE

The Model 1002S is a surge protected version of the Model 1002
that uses the latest in bi-directional, clamping, transient suppressors to
protect itself and connected equipment against harmful transient
discharges. For surge handling capability, the Model 1002S is
compliant with IEC 801.5 level 2, 1kV.

3

Terminal blocks are used to connect a single pair of bare wires to
the Model 1002. The following instructions will tell you how to open the
case, connect the bare wires and fasten the strain relief collar in place.
