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.
Note: Please refer to Figure A.4 and A.5 for location of JP7
