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.

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.
