2.6.2 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 iso-
lated digital output channels are selected by jumper JP7. Table 2.10 shows
the configuration of jumper JP7.
