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.
