Terminator resistor packs are included on each FINCH Adapter
Board. The terminators consist of a DIP resistor module
which is plugged into a DIP socket. Only the last FINCH in
a daisy-chain configuration requires a terminator resistor
pack for the Command/Data cable; the others must be removed.
A daisy-chain configuration incorporates parallel interfac-
ing of the disk drives on a common Command/Data cable. A
maximum
of four drives may be daisy-chained on the cable.
