WSI2 board
pinning
The WSI2 board has only one pinned option. The pinning defines if an
HMPU board or a K2LCN board is used as the node processor. The
interface to these two node processors is somewhat different.
Calender clock
battery
The coprocessor contains a time of day clock circuit which has a battery
backup. The clock circuits are maintained by this battery whenever node
power is removed.
This battery has a very long life (years), but it will eventually have to be
replaced.
Note the location of this battery on the coprocessor daughter board shown
in the diagram below. It is a separately listed item in the parts list.
