  • Page 8: Introduction

    SERIAL↔PARALLEL CONVERTER V AND V-DB25 2. Introduction 2.1 Description The Serial↔Parallel Converter V and V-DB25 automatically convert RS-232C serial data to parallel-data format and vice versa. Incorporating advanced microprocessor technology, the Converters are able to automatically sense and select parallel and serial modes. Requiring no AC power or batteries, the Serial↔Parallel Converters support serial data rates up to 38.4 Kbps.

  • Page 10: Configuration

    SERIAL↔PARALLEL CONVERTER V AND V-DB25 3. Configuration The Converter is simple to install and designed for excellent reliability: just set it and forget it. 3.1 Configuration Switches The Serial↔Parallel Converter V or V-DB25 uses a set of eight external DIP switches (see Figure 3-1) that allow configuration for a wide range of applications.
  • Page 11 SERIAL↔PARALLEL CONVERTER V AND V-DB25 Configuration Switches Figure 3-1. The location of the configuration switches. The Serial↔Parallel Converter V uses 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 below.

  • Page 14: Installation

    SERIAL↔PARALLEL CONVERTER V AND V-DB25 4. Installation The Converter 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. The figure below illustrates the proper connections for the standard cables.

  • Page 15: Operation

    SERIAL↔PARALLEL CONVERTER V AND V-DB25 5. Operation Once your 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. The Serial↔Parallel Converter features an easy-to- read status LED that glows red to indicate the condition of the transmission line.
