Power On Configuration
Default configuration after power on or hardware reset is to set all the iso-
lated 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 configuration
of jumper JP12.
