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.

2.0 GENERAL INFORMATION
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.
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
2.1 FEATURES
• 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 38,400 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
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.

2.2 DESCRIPTION
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.
Figure 1. The location of the configuration switches:
the Model 2026 (left) and the Model 2027 (right)
The Model 2026 and Model 2027 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.

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.

4.0 INSTALLATION
5.0 OPERATION
The Patton Model 2026 and 2027 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 2026 and 2027. 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
Model 2026 or 2027
Your cable
The Model 2026 and the Model 2027 feature easy-to-read status
LEDs that glow red to indicate the condition of the transmission line.
Figure 1 shows the location of these LEDs. The following chart
describes the LED’s various functions.
