2.2 DESCRIPTION
The Patton Model 2039 Parallel to Serial Converter
automatically converts RS-232C serial data to parallel data format and
vice versa. Incorporating advanced microprocessor technology, the
Model 2039 is able to automatically sense and select parallel and serial
modes. The Model 2039 requires no AC power or batteries and
supports serial data rates to 115.2 Kbps.
For easy configuration, the Model 2039 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 2039
measures only 2.68" x 1.25" x .75". The Patton Model 2039 comes
equipped with a DB-9 female connector on the serial side and a
Centronics 36 pin male connector on the parallel side. A six foot
integral cable is also included.

3.0 CONFIGURATION
The Model 2039 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 (301) 975-1007.
3.1 CONFIGURATION SWITCHES
The Model 2039 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.

Figure 1. The location of the configuration switches
The Model 2039 uses a miniature configuration switch package.
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 2039 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 2039 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.
