2.2  DESCRIPTION
The Patton Model 2026 and Model 2027 Parallel to Serial
Converters automatically convert RS-232 serial data to parallel data
format or vice versa.  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, the
Model 2026 and 2027 support serial data rates to 38.4 Kbps.
For easy configuration, the Model 2026 and Model 2027 feature a
convenient set of external configuration switches.  These accessible
configuration switches allow the user to control baud rate, parity, word
length and flow control.  An easy-to-read LED indicator displays status
and operating condition.
Housed in an ultra-miniature ABS plastic case, the Model 2026
comes equipped with a DB-25 female or male connector on the serial
side and a Centronics 36 pin male connector on the parallel side.  The
Model 2027 is housed in the same convenient case and comes
equipped with a DB-25 female connector on the serial side and male 
or
female connector on the parallel side.
