Power On Configuration
Default configuration after power on or hardware reset is to set all the
isolated digital output channels to open status (the current of the load
can't be sink) so that users need not worry about damaging external
devices during system startup or reset.
When the system is hot reset, then the status of isolated digital output
channels are selected by jumper JP12. Table 2-8 shows the configura-
tion of jumper JP12.
