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

 J9 and J10  Terminators
 -----------------------
 All single-drive systems have terminators J9 and J10 installed. For
 multi-drive systems, terminators J9 and J10 may only installed in the
 last drive of a daisychain configuration. All drives are shipped with
 the terminators installed.


 J18  Grounding Connector
 ------------------------
 The frame grounding connector (J18) is a Faston AMP P/N 61761-2 tap
 connector. The recommended mating connector is AMP P/N 62187-1 or
 equivalent. The hole in the Faston tap accomodates a wire size of
 18 AWG.

 Use of frame ground connection is recommended in order to reduce
 ground loops which may result in electrical noise problems.

 The address of each MegaFile Series Drive is set by installing the
 address jumper on J2 on the device electronics board. Each drive must
 have a unique address. The sequence of addressing is optional. All
 drives are shipped with address 0 preset.
