1.0 WARRANTY INFORMATION
Patton Electronics warrants all Model 2036P 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 2036P 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. They have been tested and found to comply with
the limits for Class Acomputing 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). ACertificate of Compliance is available by contacting Technical
Support.

2.2 DESCRIPTION
The Patton Model 2036P Serial to Parallel and Parallel to
Serial Converter automatically converts RS-232 serial data to parallel
data format and vice versa. Incorporating advanced microprocessor
technology, the 2036P automatically senses and selects parallel and
serial modes, as well as DCE/DTE modes. The Model 2036P supports
serial data rates to 115.2 Kbps.
For easy configuration, the Model 2036P features a convenient set
of configuration switches. These internally accessible configuration
switches allow the user to control baud rate, parity, word length and
flow control.
Housed in a miniature ABS plastic case, the Model 2036P comes
equipped with a DB-25 female connector on the serial side and a
Centronics 36 pin male connector on the parallel side. Able to recieve
power directly from the RS-232 interface, the Model 2036P also comes
with a wall-mount power supply for low power applications.

3.0 CONFIGURATION
The Model 2036P is 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 2036P uses a set of eight internal DIP switches (see
Figure 1) that allow configuration to a wide range of applications. You
must open the case to gain access to the internal switches. To open
the case, insert a small screwdriver into one of the slots on the side of
the plastic case. Then twist from side to side until the case opens.
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.

3.2 CONFIGURATION SWITCHES SW1 - SW8
This section provides detailed information about the function of
each DIP switch and lists all possible settings.
Switch 1: Hardware/Software Control/BERT Direction
The setting for Switch 1 determines whether the 2036P uses hardware or software (i.e. XON/XOFF) flow control. Switch 1 is alternatively used to determine the direction of the BERT output message whenever the BERT is activated (See Switch 2, below).
Switch 2: Bit Error Rate Test (BERT)
Use Switch 2 to activate a Bit Error Rate Test (BERT) in the direction of the serial
or
parallel interface. This test can be used to determine whether the 2036P is working properly. When BERT is activated,
the 2036P outputs the following Barber Pole pattern, which represents
every ASCII character on a standard US keyboard:
0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\}^_’abcdefghijklmnopqrstuvwxyz{|}~
NOTE: When you activate the BER Test, the 2036P “memorizes” the setting of
Switches S1, S3,S4, S5, S6, S7, and S8 to perform the test. If you modify any of
these switches, you must de-activate Switch 2 in order for the changes to take effect.

4.0 INSTALLATION
The Patton Model 2036P 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 2036P. If you have special-ordered a non-standard connector, your connections may be different.
4.1 POWER CONNECTION
In many cases, the Model 2036P will run without being connected
to external power. However, additional power may be necessary in
certain applications that use low power RS-232 devices.
The 120VAC U.S. wall transformer version supplies +9V regulated
DC up to 500mA. Connect this wall transformer to the Model 2036P
by means of a cannon jack on the side panel. The Model 2036P is
powered-up as soon as it is plugged into an AC outlet–there is no
power switch.
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.
