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. +--------------------------------+------------+---------------------+ |Configuration | Terminator | Terminator Switch | | | Module | (JP224, pins 1-6) | +--------------------------------+------------+---------------------+ |Single drive on cable B | MOUNTED | 6xxxx+ CLOSED 1-6| |All drive in Radial connection | MOUNTED | +xxxx+ CLOSED 1-6| |The lst drive in Daisy Chain | MOUNTED | +xxxx+ CLOSED 1-6| | | | +----1 | +--------------------------------+------------+---------------------+ |All drives except the last one | REMOVED | 6----+ OPEN 1-6 | |in Daisy Chain | | +----+ | | | | +----+ | | | | +----1 | +--------------------------------+------------+---------------------+ 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.
JP281 CLOSED The last Slave drive
OPEN All drives except the last Slave drive
A drive as shipped is mounted with Terminator Switch II.

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.
