5.4 AUXILIARY RS232 INTERFACE
The auxiliary serial interface is used exclusively for RS232 point-to-point connections.
The parameters relative to the aux interface (baud rate, data bits, etc.) as well as particular
communication modes such as LOCAL ECHO can be defined using the Genius™ utility
program or Genius™ based Host Mode Programming installed from the CD-ROM.
