N drives

Terminating the drive

“N” model drives are terminated with permanently mounted IC

active terminators. If you install one of these drives and it is not

on the end of the SCSI bus, disable the terminators by removing

the jumper “TE” from pins 15 and 16 of connector J2 (see Fig-

ure 8). If you install the drive on the end of the SCSI bus, enable

termination by installing a jumper on pins 15 and 16 of connector

J2.
