Drive model "WC" plugs directly into a bulkhead or PCB
mounted connector. Systems using these drives have made
provisions for terminators and selecting most options, so only
"Write Protect" and "Parity Disable" options (on J2) must be
considered for possible setting by a person installing a replace-
ment drive (usually no change is needed). Most systems using
"WC" model drives use drives that have unique drive internal
control firmware, so "off the distributor shelf" drives probably
will not work in these installations. Firmware cannot be changed
on these drives. If you are upgrading by installing an additional
drive, consult the system documentation or system purchase
source for help in setting up drive ID, options and getting termi-
nation correct.
I/O line terminators
The SCSI I/O lines must be "terminated" at the drive connected
to the end of the cable. If your new drive is a model "N" or "W"
and is to be connected at the end of the cable, a jumper plug
should be installed on J2 (one of the smaller plugs) at the loca-
tion shown in Figure 3d where it says "Terminator Enable."
On J2, the "Terminator Power" (TP) jumper should be left in the
"Term. Power From Drive" position, unless otherwise directed
by your computer documentation.
