CHAPTER 1: Specifications Size — 3.4"H x 1.3"W x 0.8"D (8.7 x 3.3 x 2 cm) Weight — 2 oz.
SERIAL↔PARALLEL CONVERTERS 2. Introduction 2.1 Description The Serial↔Parallel Converters automatically convert RS-232 serial data to parallel data format and vice versa, in one direction at a time. 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, these Converters support serial data rates to 38.4 kbps.
CHAPTER 2: Introduction 2.2 Features • Converts parallel data to serial data and vice versa. • Automatically selects parallel-to-serial and 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.
SERIAL↔PARALLEL CONVERTERS 3. Configuration and Installation The Converter is simple to install and extremely reliable. The following instructions will help you set up and install your converter properly. If you have any questions, please call Black Box Technical Support at 724-746-5500. 3.1 Configuration Switches The Converters each use a set of eight external DIP switches (see Figure 3-1) that allow configuration to a wide range of applications.

SERIAL↔PARALLEL CONVERTERS The Converters 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 3-2. Default settings (noted with an asterisk) for the DIP switches are shown in the table on the following page. Set up the Converter by selecting the appropriate DIP-switch settings for your application.

SERIAL↔PARALLEL CONVERTERS 3.2 Installation The Converter is very simple to install. Once you have configured the DIP switches, just plug your Converter into a standard cable and you’re ready to go. Figure 3-3 shows the proper connections. Figure 3-3. Typical installation.
CHAPTER 4: Reading the LED 4. Reading the LED 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 Converter indicates data activity by blinking. When the Converter has another message to report, the LED blinks according to the codes in Table 4-1 below. Table 4-1.
SERIAL↔PARALLEL CONVERTERS 5. Troubleshooting If your Serial↔Parallel Converter seems to be malfunctioning, do not attempt to alter or repair the unit. Contact Black Box Technical Support at 724-746-5500. Before you do so, make a record of the history of the problem. We will be able to provide more efficient and accurate assistance if you have a complete description, including: • The nature and duration of the problem. • When the problem occurs. • The components involved in the problem.
