This warranty is limited to defects in workmanship or materials, and does not cover customer damage, abuse or unauthorized modification. If this product fails or does 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 this product.

1.1 RADIO AND TV INTERFERENCE
The Model 2025 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. The Model 2025 has been tested and found to comply with the limits for a Class A computing device 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 the Model 2025 does 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).
1.3 SERVICE
All warranty and non-warranty repairs must be returned freight prepaid and insured to Patton Electronics. All returns must have a Return Materials Authorization number on the outside of the shipping container. This number may be obtained from Patton Electronics Technical Support: (301) 975-1007; http://www.patton.com; or,

2.2 DESCRIPTION
The Patton Model 2025 Parallel to Serial Converters
automatically convert RS-232 serial data to parallel data format and vice versa. Incorporating advanced microprocessor technology, the Model 2025 is able to automatically sense and select parallel and serial modes, as well as DTE/DCE modes. The Model 2025 requires no AC power and supports serial data rates from 300 to 38,400 bps.
For easy configuration, the Model 2025 features a convenient set of configuration switches. The 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 2025 measures only 2.62” x 1.26” x .76”. The Patton Model 2025 comes equipped with a DB-25 female connector on the serial side, and a Centronics 36 pin male connector on the parallel side. A six foot integral cable is also included.
The Model 2025 is simple to install and designed for excellent reliability: just set it and forget it. The following instructions will help you set up and install the converters properly. If you have any questions, please call Patton Technical Support at (301) 975-1007.
3.1 CONFIGURATION SWITCHES
The Model 2025 uses 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 2025 uses a
miniature
configuration switch package (see Figure 2). 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.

4.0 INSTALLATION
5.0 OPERATION
The Patton Model 2025 is very simple to install. Once you have configured the DIP switches, just plug it in like a normal cable and you're ready to go. Figure 3 illustrates the proper connections for the standard cables. If you have special-ordered a non-standard connector, your connections may be different.

Figure 3. Installing the Model 2025
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 2025 features an easy-to-read status LED that glows red to indicate the condition of the transmission line. Figure 1 shows the location of the LED. The following chart describes the LED's various functions.
LED Codes
● ● ——— ● ● ——— Computer is sending data
——— ——— ——— Serial device is connected; computer is
not sending data
● ● ——— ● ● ——— Both serial and parallel devices are
connected; computer not sending data
——— ——— Printer not ready, data held in buffer
● ● ● ● ———● ● ● ● Computer ignoring flow control, data lost
The red LED indicator blinks to show data activity. Since there is only one indicator, it uses different LED codes to demonstrate various messages. The following chart describes these codes:
