1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model 2029 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 2029 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 2029 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 2029
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.

2.2 DESCRIPTION
The Patton Model 2029 Parallel to Serial Converter

automatically converts RS-232C serial data to parallel data format and
vice versa. Incorporating advanced microprocessor technology, the
Model 2029 is able to automatically sense and select parallel and serial
modes. Requiring no AC power, the Model 2029 supports serial data
rates to 38.4 Kbps.

For easy configuration, the Model 2029 features a convenient set

of external configuration switches. These accessible configuration
switches allow the user to control baud rate, parity, word length and
flow control. An easy-to-read LED indicator displays status and
operating condition.

Housed in an ultra-miniature ABS plastic case, the Model 2029

measures only 2.68” x 1.25” x .75”. The Patton Model 2029 comes
equipped with a DB-9 female connector on the serial side and a
Centronics 36 pin male connector on the parallel side. A 6-foot integral
cable is also included.

3.0 CONFIGURATION

The Model 2029 is simple to install and designed for excellent
reliability. The following instructions will help you set up and install the
converter properly. If you have any questions, please call Patton
Technical Support at [phone].

3.1 CONFIGURATION SWITCHES

The Model 2029 uses a set of eight external DIP switches (see
Figure 1) that allow configuration to a wide range of applications.
Because all eight switches are in one externally accessible DIP switch
package, there is no need to open the case for configuration. The
configuration switches allow you to select data rates, parity, word length
and flow control selection. The following section describes all switch
locations, positions and functions.

To configure your unit, use a small screwdriver and gently push each
switch to its proper setting. The ON and OFF positions are shown in
Figure 2. Default settings for the DIP switches are shown in the table
on the following page. Detailed settings follow the table.

4.0 INSTALLATION

The Patton Model 2029 is very simple to install. Once you have
configured the DIP switches, just plug it in like a normal cable and
you're ready to go. Figure 3 illustrates the proper connections for the
standard cables. If you have special-ordered a non-standard
connector, your connections may be different.

5.0 OPERATION

Once your interface converter is properly configured and installed,
it should operate transparently—as if it were a standard cable
connection. Operating power is derived from the RS-232 data and
control signals; there is no “ON/OFF” switch.

5.1 LED STATUS MONITORS

The Model 2029 features an easy-to-read status LED that glows
red to indicate the condition of the transmission line. Figure 1 shows
the location of the LED. The following chart describes the LED's
various functions.

The red LED indicator blinks to show data activity. However, since
there is only one indicator, it uses different LED codes to demonstrate
various messages. The following chart describes these codes:
