CHAPTER 3: Configuration 3. Configuration The Micro-MiniBuffer has one input port and one output port. Each serial port must be configured individually for speed, parity, number of stop bits, data format, and handshaking method. Table 3-1 lists these settings. The unit is also equipped with four switches. Copy\Pause and Reset are located on the front panel. - Page 11 MICRO-MINIBUFFER Table 3-1. Switch Settings.

CHAPTER 4: Operation 4.2.1 H ARDWARE ANDSHAKING When the unit’s buffer is nearly full on the input end, it changes Pin 20 from a high voltage to a low voltage. When the output device (printer) has emptied the unit’s buffer so that more input data can be accepted, the Micro- MiniBuffer raises Pin 20 to a high level signal. -

CHAPTER 5: Troublshooting 5. Troubleshooting Here are some basic steps to follow when troubleshooting the Micro- MiniBuffer. 1. If the Self test won’t output to the printer: For serial output, be sure DTR is high on the output port. 2. If Data garbles to printer after printing a few pages: Check word structure option on serial port to be sure the Micro- MiniBuffer is setup the same way as the equipment connected to it.
