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

 User Selectable Options
 -----------------------
 The BASF 6180 has 8 switches for the selection of different options:

   +------+
   | O--O |1   Drive Select 1
   | O--O |2   Drive Select 2
   | O--O |3   Drive Select 3
   | O--O |4   Drive Select 4
   | O--O |5   DRSEL
   | O--O |6   PWRON
   | O--O |7   REZERO
   | O--O |8   PERMSELD
   +------+

 Four switches (1 - 4) are used to set the drive address. Drive
 selection is performed when the DR SEL (Drive Select) signal
 corresponding to the switch setting is active.

 Two switches (5 and 6) are used to control the condition for the
 spindle motor start. Depending on the switch setting the Spindle
 Motor is started either with the first active going edge of the
 corresponding DR SEL (Drive Select) signal or when DC power is
 provided to the drive. Only one of two switches may be set.

 Switch 7 is used to enable an automatic Rezero operation after the
 Spindle Motor has reached full speed.

 Switch 8 allows to select a drive permanently and independent of the
 state of the DR SEL (Drive Select) signals.


 Drive Selection
 ---------------
 Each drive is assigned an address by setting the corresponding Drive
 Select switch in the drive. Drive selection is done by activating
 the corresponding DR SEL (Drive Select) signal through the control
 unit. The selected drive responds the to all input signals and
 enables its output drivers.

 Alternatively the drive may be permanently selected through an option
 switch if only one drive is connected to the controller.


 Rezero
 ------
 After Power On the drive's positioning system must be recalibrated
 by performing a seek to Track Zero. This can be done either
 automatically by the drive or by the controller through the interface
 in the following way:

 - select drive

 - deactivate DIR IN (Direction In)

 - provide STEP pulses until TRK 0 (Track 0) becomes active

 The BASF 6180 may be operated only when the Face Place is in a
 vertical plane. The maximum deviation is an angle of 13 degrees. From
 the remaining four possible orientations only three are allowed for
 operation. These are with the Read-Write-Control PCB either on the
 left or right side or on top of the drive. Operation with the Read-
 Write-Control PCB at the bottom of the drive is not allowed.


 Housing
 -------
 The sealed module consists of an aluminium molded chassis and cover.
 A closed loop air filtering system inside constantly cleans the air
 particles which may be generated by head to disk interference. An
 absolute breather filter for pressure equalization with the ambient
 air pressure protects against environmental contamination.


 Physical Interface
 ------------------
 The physical interface between the BASF 6180 and the controller is
 done via three or four connectors. One provides the control and
 status lines through the "A"-cable which may be daisy chained.
 The second one provides the read/write signals to the star connected
 "B"-cable. The other connectors are used to supply DC power and for
 optional frame grounding.


 Interface Connector J1, "A"-cable
 ---------------------------------
 The "A"-cable is connected to the PC-board via a 34 pin card edge
 connector. Recommended mating connector is AMP P/N 88 373-3, or
 equivalent.

 The "A"-cable may be daisy-chained if more than one drive is
 connected to the controller. The cable may be flat ribbon or
 twisted pair with a maximum total length of 6m (20 ft).


 Interface Connector J2, "B"-cable
 ---------------------------------
 The "B"-cable is connected to the PC-board via a 20 pin card edge
 connector. Recommended mating connector is AMP P/N 88 373-6, or
 equivalent.

 The "B"-cable must be radially connected if more than one drive is
 connected to the controller. The cable may be flat ribbon or
 twisted pair with a maximum total length of 6m (20 ft). The cable
 impedance should be around 105 Ohms.


 Power Connector J3
 ------------------
 The DC-power connector is a four pin connector. Recommended mating
 connector is AMP P/N 1-480424-0 with pins 350078-4, or equivalent.

 Pin 1  +12 VDC
 Pin 2  GND 12V
 Pin 3  GND 5V
 Pin 4  + 5 VDC


 Frame Ground Connector J4
 -------------------------
 The frame of the BASF 6180 may be connected to the system ground
 through a separate cable connected to J4. Normally the frame of the
 BASF 6180 is connected to logic ground. If JJ4 is used, then the
 solder jumper wire JJ2 at location 1G of the Read-Write-Control PCB
 should be removed in order to avoid ground loops.

 Recommended mating connector for J4 is AMP P/N 62187-1 or equivalent.

 General Description
 -------------------
 The BASF 6180 is a family of 5.25" Fixed Disk Drives. The three
 models of the family offer capacities of 6.38 MBytes (BASF 6182),
 9.57 MBytes (BASF 6183), and 14.35 MBytes (BASF 6184). The BASF 6180
 stores the information on up to 3 non-removable disks and up to 230
 cylinders.

 The BASF 6180 uses the industry standard interface and dimensions to
 ease system integration. Up to four BASF 6180 may be connected to
 one controller. For systems requiring removable media it is re-
 commended to use the BASF 6180 in combination with BASF Mini Floppy
 Disk Drives, which offer a capacity of up to 1 MByte.
