2. Introduction The Serial↔Parallel Converter VI converts RS-232 serial to IBM PC (Centronics compatible) parallel or vice ® ® versa—you choose the direction of conversion with a switch. The Converter supports both X-ON/X-OFF and DTR/CTS serial hardware handshaking, and Busy/Acknowledge parallel handshaking. Since the Converter is powered by the connected devices, it needs no external power source.

CHAPTER 2: Introduction NOTE In the applications for which the Converter was designed and tested, it is installed between PCs and printers. The Converter should function normally in such environments. However, the Converter will not work with certain serial devices that do not comply with the RS-232 specifications for voltage.
3. Installation NOTE Make sure the computer and any other connected devices are turned off before you make any connections to the Converter. The Converter plugs directly into a computer’s DB25 male (DTE) serial port, or into a computer’s DB25 female parallel-printer port.

After connecting the hardware, set up the Converter by selecting the appropriate DIP-switch settings for your application (see the chart on the next page).

Bits None/8 Odd/7 Even/7 Self-Test Conversion S→P P→S RTS for Power Enabled Disabled NOTE The Converter reads DIP-switch settings during power-up. When the self-test mode is selected, the Converter will continually check the status (on or off) of this position until the self-test mode is turned off, after which the position will no longer be checked.

CHAPTER 3: Installation The installation is finished now. If your connection is working, you don’t have to do anything else. If you want more information on the self-test mode, read Chapter 4. If you have problems, read Chapters 4 and 5.
4. The Self-Test Mode The Converter’s self-test mode confirms the successful connection and operation of the Converter from the internal processor through the output port. It does not specifically verify the correct connection or operation of the input port, but the serial handshake leads that power the Converter must be working for a consistent self-test to be output to the parallel device when the Converter is connected in serial→parallel mode.
Page 18
CHAPTER 4: The Self-Test Mode When the Converter is to be used in parallel→serial mode, this is how to run the self-test: 1. Connect the Converter’s serial port to the serial device (usually a printer). Use a straight-through- pinned RS-232 cable. 2.

will not be enough to turn the Converter off or to reset it. This is because the Converter will still be drawing power from the PC’s parallel port and will remain on even though power has been removed from the serial output port.
CHAPTER 5: Troubleshooting 5. Troubleshooting 5.1 Calling Black Box If you determine that your Serial↔Parallel Converter VI is malfunctioning, do not attempt to alter or repair the unit. It contains no user-serviceable parts. Contact Black Box at 724-746-5500. Before you do, make a record of the history of the problem.
• Package it carefully. We recommend that you use the original container. • If you are shipping the Serial↔Parallel Converter VI for repair, make sure you include everything that came in the original package. Before you ship, contact Black Box to get a Return Materials Authorization (RMA) number.
