DRIVE ADDRESS AND OPTION PATCHING
The
drive
address
and
option
patching
is
determined
by the
programmable shunt, located at U19
on
the logic circuit board.
The
DSO through TIS3 Jumpers determine the drive address.
The MX jumper is
used
only in single drive systems.
Drive address and option patching
jumpers are located in Figure 3-3.
The
program
shunt is AMP Part Number 435704-7.
The shunt positions
can
be
cut using
AMP's
tool, Part Number 435705.
The shunt is in-
stalled
in a DIP socket.
At the user's option,
it can
be
removed and
replaced by a DIP switch.
OSO Through OS3 Jumpers
When
daisy
chaining
two
or
more drives to a controller, the Drive
Select
(DS)
jumpers
patch
the drive select control signal to enable
the logic
of the proper drive.
Normally, all the shunt jumpers would
be
cut, except for the DS jumper that addresses each individual drive
in
the
daisy
chain.
The
terminator
pack, 2F, located
on the
logic circuit
board
should
be
installed
in
the last drive of the
daisy chain.
