[ Connecting a Daisy Chain Configuration ]
This unit uses a SCSI interface. A daisy chain configuration enables
connection of a maximum of 8 SCSI devices.
(1) Set SCSI ID using bit 1 - 3 of jumper terminals ® (see
figure below),
(2) Bit 9 of jumper terminals ® shall be OFF, only when the
unit is the last SCSI device on the daisy chain..
NOTE:
e Make sure the overall length of the SCSI cable does not exceed 6
meters (The SCSI cable 1$ sold separately.)
o Be sure not to duplicate the SCSI ID.
{Setting Jumper Terminals Ф]
@ SCSI ID (bits 1 to 3)
Sets this unit's SCSI ID (see figure below),.
(g) Parity check (bit 4)
Determines whether to perform the SCSI data bus parity check..
Performs parity check when OFF.
© Bits 5, 6 are reserved Shaii be set to OFF,
® Mode swiichirig (ШОЕ, bits 7, 8)-
-
Determines the operation mode after reading the bits following
power-on or SCSI RESET
e MODE 0; Rewritable mode
о MODE 1: WORM mode
e MODE 2: SCSI-2 mode
« MODE 3: Reserved
' Mode can also be selected by an SCSI command
Ф SCSI terminator (bit 9)
Determines whether or not the unit’s SCSI terminator is to be
used

NOTE;
0 All settings are in the OFF at the time of shipment from the factory
When setting to the ON, insert the supplied jumper pin.
0 Use the factory setting (OFF) for bits 4 - 6 except
o Be sure not to lose the jumper pin. When switched OFF, it is conve­
nient to leave one side only connected
0 When setting with an external switch, remove all jumper pins, and
transmit the signals using a 2 54 mm pitch 2-line 18-pin connector
