1.1 RADIO AND TV INTERFERENCE
The Model 2026 and Model 2027 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.

2.2 DESCRIPTION
The Patton Model 2026 and Model 2027 Parallel to Serial
Converters automatically convert RS-232 serial data to parallel data
format or vice versa. Incorporating advanced microprocessor
technology, they are able to automatically sense and select parallel and
serial modes, as well as DCE/DTE modes. Requiring no AC power, the
Model 2026 and 2027 support serial data rates to 38.4 Kbps.
For easy configuration, the Model 2026 and Model 2027 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 2026
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 2027 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.

3.0 CONFIGURATION
The Model 2026 and 2027 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 2026 and 2027 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.
