4.1 Hardware Configuration
4.1.1 Serial Mode Configuration
The CP346 offers the possibility to configure the operation mode of each channel either with a
per default mounted eight Port DIP switch or with solder jumpers (maybe as replacement in
case of special conformal coating requirements). Because the switches are implemented as
GND switches and the DIP switch and the jumper option are wired OR, it is also thinkable to
use both, where a set switch/jumper has always the higher priority.
Two dedicated switches/jumpers are necessary to configure each channel, where the following
tables show the possible settings:
