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

 JP224 Terminator Switch I
 -------------------------
 Each drive in Radial connection of cable B and last end of the drives
 in Daisy Chain connection of cable B should be terminated. Since a
 terminator module (TM223) and Terminator Switch I (JP224) are
 provided to all drives as shipped, remove both of them except the
 last drive's ones in case of Daisy Chain connection.

 At the time of shipment, Terminator Module and Terminator Switch I
 are mounted on Terminator socket.

Synchronized Spindle Signal Terminator Switch II JP281
------------------------------------------------------
Synchronized Spindle Signal is terminated via JP281 to terminator
register on the PCB. When the synchronized spindle option is used,
JP281 shall be removed except the last drive's one in Daisy Chain of
Synchronized Spindle Signal.

 At the time of shipment, Drive #1 is selected.

JP213 7-8 Write Protect Jumper
-------------------------------
Write operation of a drive is inhibited by setting a jumper on JP213,
pin 7-8 (Write Protect mode), which condition will generate ATTENTION
status upon receiving of WRITE GATE-N signal.

 JP213 7-8 CLOSED  Write Protect
           OPEN    Write Enable

At the time of shipment, "Write Enable" mode is selected.

 JP282 1-2  Sector Mode Select
 -----------------------------
 JP282 1-2 CLOSED  Hard Sector
           OPEN    Soft Sector

The drive with Hard Sector mode issues clock on J1-pin 16 and J2-pin
2. "SET CONFIGURATION" command takes precedence over this Jumper
setting function.

At the time of shipment, "Hard Sector" mode is selected.

JP282 7-8 Motor Control Jumper
-------------------------------
When the "Start/Stop Spindle Motor" option is to be used, set the
jumper as "Supported" before DC power on.

 JP282 7-8  CLOSED  Not Supported (Factory Setting)
            OPEN    Supported

JP282 3-6 Synchronized Spindle Mode Select Jumper
-------------------------------------------------
Synchronized spindle mode can be selected by using the jumper switch
(JP282, pin 3-6). This Jumper Setting will be aborted by the follow-
ing Set Configuration command. Set tge jumpers, before turning on the
DC power.

 pin 3-4 and 5-6 CLOSED  Off Line (Factory setting)
             5-6 CLOSED  Slave  (3-4 OPEN)
