1.0 WARRANTY INFORMATION
Patton Electronics warrants all Model 2036 and 2037
components to be free from defects, and will—at our option—repair or
replace the products should they 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 these products fail or do 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 these products. 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 2036 and Model 2037 generate and use 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. They have been tested
and found to comply with the limits for Class A computing devices 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
they do 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.

3.0 CONFIGURATION
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
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.
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.
2.0 GENERAL INFORMATION

2.2 DESCRIPTION
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.
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.

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 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.
Please refer to the following key to interpret the above status
codes:
4.0 INSTALLATION
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.
