SERIAL↔PARALLEL CONVERTER (38.4 kbps) 2. Introduction 2.1 Description The Serial↔Parallel Converter (38.4 kbps) converts RS-232C serial data to parallel data and vice versa. Incorporating advanced microprocessor technology, the Converter automatically senses and selects parallel and serial modes, as well as DTE/DCE modes. The Converter requires no AC power and supports serial data rates from 300 to 38,400 bps.

CHAPTER 2: Introduction • Automatic DCE/DTE sensing and selection. • Built-in 1-kbit buffer prevents data loss. • Serial data rates up to 38,400 bps. • No AC power required. • Supports both software and hardware flow control. • Ultra-miniature size. •...
SERIAL↔PARALLEL CONVERTER (38.4 kbps) 3. Configuration 3.1 Configuration Switches The Serial↔Parallel Converter (38.4 kbps) uses a set of eight external DIP switches (see Figure 3-1) that allow configuration to a wide range of applications. Because all eight switches are in one externally accessible DIP- switch package, you don’t have to open the case for configuration.
Page 14
CHAPTER 3: Configuration The Converter uses a miniature 8-position DIP switch package (see Figure 3-2). To configure the 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.

SERIAL↔PARALLEL CONVERTER (38.4 kbps) 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 Converter features an easy-to-read status LED that glows red to indicate the condition of the transmission line.
