Use case C - Switch configuration
Use case D –Transparent IO Downstream TARGET

Configuration and DIP-switches

DIP switch bank SW 1 - SWMODE
This DIP should normally be kept in factory default mode. These DIP switches are used to directly control the
PES24NT6G2 Software MODE. Please refer to the PES24NT6G2 data sheet for details. The most useful options
are documented in the table below.

DIP switch bank SW 2 –configuration
This DIP Switch is used to configure transparent and non-transparent modes and manipulate clock
source and reset functionality. Please note that the Transparent Target functionality requires a non-
default setting of DIP SW 1 described on the previous page.
