Terminating Resistor Setting
----------------------------
SCSI interface needs the terminating resistor only set both ends of
the interface cable. The terminating resistor of the disk drive can
be installed to the socket on Single In Line. If the disk drive is
used with connecting the both ends of the interface cable, install
the terminating resistor. The recommended terminating resistor for
this disk drive is as below:
Terminating Resistor: BECKMAN INDUSTRIAL MII-5-221/33IJS
OR EQUIVALENT RESISTOR
