 Jumper Setting
 ==============

 There are two switches on the main circuit board of this drive.


 SW1 Termination Switch
 ----------------------
        +-----------+
        |o o o o o o|ON
        |x x x x x x|OFF
        +1-2-3-4-5-6+
         +-+-+-+-+-+------- Termination Switch

 To provide termination for the last unit, al switches of SW1 should
 be set in the ON position. On all other units, all the switches of
 SW1 should be set in the OFF position.


 SW2  Drive Select
 -----------------
        +---------------+
        |x o o o x o o o|ON
        |o x x x o x x x|OFF
        +1-2-3-4-5-6-7-8+
         | | | | | | | +---  Set OFF position
         | | | | | | +-----  Set OFF position
         | | | | | +-------  Set OFF position
         | | | | +---------  RADIAL (R)
         | | | +-----------  Drive Select 1 (DS1)
         | | +-------------  Drive Select 2 (DS2)
         | +---------------  Drive Select 3 (DS3)
         +-----------------  Drive Select 4 (DS4)


 In multiple unit connection it is necessary to configure each drive
 with a unique address.

  *Mark is printed on Printed Circuit Board (PCB).


 The control cable allows for a daisy chain connection of up to four
 drives.

 The switch block has DRIVE SELECT switched off with the "radial"
 option selected. Each drive is shipped with the switch block marked
 "R" switched on, resulting in the daisy chain operation. In this
 case, input and output signals are enabled when the appropriate
 DRIVE SELECT line is activated.

 When the switch block marked "R" is switched off, all inout and out-
 put signals are enabled even if the drive is not selected.

 However, the front panel LED will not be on. DRIVE SELECT must be
 activate to light the LED.
