Figure A-1. External Terminator Installation
Figure A-1 shows two different types of external SCSI connectors.
1.Configuration"A" shows an extended external SCSI connector and bail locks for
holding the terminator in place. This configuration is used on almost all of Alpha
Micro’s currently available product. The terminator is installed by sliding it over the
connector and then latching the bail locks into the notches in the terminator.
2.Configuration"B" shows a flush mounted external SCSI connector. This is the
configuration used on AM-1000 and AM-1200 computers, as well as AM-1001
subsystems. In this configuration, the terminator inserts into a cutout in the sheet
metal and over the SCSI connector. The terminator is held in place with two
#4screws and washers.
A.1.1Termination Procedure (Without External Terminator)
1.For all AM-1000 and AM-1200 AMOS based computers, the last SCSI device
attached to the connector farthest down the cable away from the CPU board must
have its terminators installed. If only one SCSI device is installed, that device must
be terminated.
