Notes:
Drive Addressing and Interface Termination



RN1 Interface Terminator
  The Interface Terminator factory installed at RN1 will provide proper
  termination for the interface lines. When daisy-chaining multiple drives,
  leave the terminator installed only in the last physical drive on
  the daisy chain; remove the terminator from each of the other drives. In
  most PC/AT installations, the C: drive is actually at the end of the cable
  and should retain the terminator.

DA1, DA2, DA3 Drive Address Jumpers
  The drive address jumpers are identified as DA1, DA2 and DA3.
  Address selection is binary, as shown in the table below.
  The ESDI controller's documentation will specify the drive address to use.


Drive
Address
Select Jumpers
DA3 DA2 DA1
1 out out in
2 out in out
3 out in in
4 in out out
5 in out in
6 in in out
7 in in in

  "Drive address 0" (no jumper at DA1, DA2, or DA3) is a "deselect"
  (i.e., no drive selected). Drives are factory configured as Drive
  Address 1. For many multiple drive installations, each drive must
  have a unique address. An exception is that for every drive in
  a PC/AT installation, verify that only Drive Address is at DA2;
  move  the jumper if necessary(the special twisted interface cable
  that is generally used takes care  of assigning a unique address
  to each drive). PC/AT controller can typically support a maximum
  of two drives.

W5 Selects the Spindle Control Option.
  W5 selects the spindle a control option. If W5 is installed, the
  drive waits for a Start Spindle command (after power is  applied)
  to start the spindle motor. If W5 is not installed (the factory
  default configuration), the drive automatically starts the spindle
  motor at power-on. W5 is not installed for PC/AT applications.

W1 Selects the Sectoring Mode.
  If W1 is installed, the drive operates in the soft-sectored mode.
  If W1 is not installed (the factory default configuration), the
  drive operates in the hard-sector mode. W1 is not installed for
  most PC/AT in applications.

W2, W3, W4 Sector Size Option
  The number of bytes per sector may be specified using the Set
  Bytes Per Sector command or by selecting a default sector
  configuration with jumpers W2, W3, and W4 as follows:


Jumpers Sectors Bytes/Sector
W4 W3 W2 Per Track Formatted Unformatted
out out out 35 512 595
*out out in 36 512 578
out in out 19 1024 1096
out in in 9 2048 2314
in out out 5 4096 4166
in out in 32 512 651
in in out 64 256 325
in in in 1 20,832 20,832

  * This is the default (factory installed) configuration and is
   recommended for PC/AT applications
