2.0 GENERAL INFORMATION
3.0 CONFIGURATION
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 or problems
arise during installation or use of this product, please do not hesitate to
contact Patton Electronics Technical Support at (301) 975-1007.
The Model 2036 and 2037 are simple to install and designed for
excellent reliability. The following instructions will help you set up and
install your converter properly. If you have any questions, please call
Patton Technical Support at (301) 975-1007.
3.1 CONFIGURATION SWITCHES
2.1 FEATURES
The Model 2036 and 2037 each use 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.
• Converts parallel data to serial data or vice versa
• Automatically selects parallel-to-serial or serial-to-parallel operation
• Automatically selects DCE/DTE modes
• Serial data rates to 115,200 bps
• No AC power required
• Supports both software and hardware flow control
• A five-state LED monitors status and diagnostics
• External configuration switches
• Ultra-miniature size
• Made in the USA

2.2 DESCRIPTION
Configuration
Switches
The Patton Model 2036 and 2037 Parallel to Serial Converter
automatically convert RS-232 serial data to parallel data format or vice
versa. Incorporating advanced microprocessor technology, the Model
2036 and 2037 automatically sense and select parallel and serial
modes, as well as DCE/DTE modes. Requiring no AC power, the
Model 2036 and 2037 support serial data rates to 115,200 kbps.
For easy configuration, the Model 2036 and 2037 feature 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.
Figure 1. The location of the configuration switches:
the Model 2036 (left) and the Model 2037 (right)
The Model 2036 and 2037 each use 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.
Housed in an ultra-miniature ABS plastic case, the Model 2036
comes equipped with a DB-25 female or male connector on the serial
side and a Centronics™ 36 pin male connector on the parallel side.
The Model 2037 is housed in the same convenient case and comes
equipped with a DB-25 female connector on the serial side and male or
female connector on the parallel side.

4.0 INSTALLATION
5.0 OPERATION
The Patton Model 2036 and 2037 are very simple to install. Once
you have configured the DIP switches, just plug your converter in to a
standard cable and you’re ready to go. Figure 3 illustrates the proper
connections for the Model 2036 and 2037. If you have special-ordered
a non-standard connector, your connections may be different.
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 2036 and 2037 feature an easy-to-read LED that shows
the operating status of the Model 2036. Figure 1 (page 4) shows the
location of these LEDs. The following chart describes the LED’s status
codes.
