 J1 Drive ID
 -----------
 Connector J1 on the drive module is used to select drive configura-
 tion options. The connector has eight jumper pin pairs numbered 0
 through 7. Each selection is made by placing a jumper across opposing
 pins.

 Your drive unit is shipped with all the jumpers in place. This means
 that the device address is present to 0. To alter the device address,
 use jumpers 0 through 2 according to the table below.

 Remote Device Address Selection by SCSI Connector
 -------------------------------------------------
 When all three jumpers (0-2) are left in place for ID=0, the drive
 will use any acitve encoded SCSI ID number on the vendor-specific
 conncetor at the rear of the drive. If there is not an active ID
 address on pins A5-A7, the drive will assume the ID is 0.

 1 = TTL high
 0 = TTL low


 Activity LED Signal
 -------------------
 There is not a Light Emitting Diode (LED) located on the drive.
 However, the Activity LED signal on pin A8 of the vendor-specific
 portion of the SCSI connector may be used to drive an external LED.
 When the LED is on, it indicates the drive is processing SCSI
 commands from the host.


 SCSI Terminators
 ----------------
 The DSP2022S drive does not have SCSI bus termination on it. Bus
 termination is must be accomplished externally. If you leave jumper
 7 in place, the drive will supply power for bus termination through
 the SCSI cable pin 24. Remove this jumper if you do not need this
 cable termination power from the drive. Termination is needed only at
 the ENDS of the SCSI bus.

 Notes On Installation
 =====================

 SCSI Connector Location
 -----------------------
 The interface connector is located on the electronic module side of
 the drive. It consists of two rows of 25 pins on 2 mm centers.


 SCSI Interface Cable
 --------------------
 A standard 0.1 inch SCSI flat ribbon cable may be attached to the
 drive through an adapter made by 2.5 inch disk drive vendors.

 A 1 mm flat ribbon cable may also be used with a suitable 2 x 25, 2
 mm IDC connector (e.g. Molex 87259-5016). Use the 1 mm cable with the
 following caution.

 CAUTION
 It is recommended that only one disk drive be powered from a given
 segment of 1 mm cable.
