Glossary of Terms and Abbreviations
SCAM
SCSI Configured Automatically or SCSI Configured Automatically
SCAM is the new automatic ID assignment protocol for SCSI. SCAM
frees SCSI users from locating and setting SCSI ID switches and
jumpers. SCAM is the key part of Plug and Play SCSI.
SEL/
Select
Used by an initiator to select a target or by a target to reselect an initiator.
Single-Ended
Configuration
An electrical signal configuration that uses a single line for each signal
referenced to a ground path common to the other signal lines. The
advantage of a single-ended configuration is that it uses half the pins,
chips, and board area that differential/low voltage differential
configurations require. The main disadvantage of single-ended
configurations is that they are vulnerable to common mode noise. Also,
cable lengths are limited.
Synchronous
Transmission
Transmission in which the sending and receiving devices operate
continuously at the same frequency and are held in a desired phase
relationship by correction devices. For buses, synchronous transmission
is a timing protocol that uses a master clock and has a clock period.
Target
An SCSI device that performs an operation requested by an initiator.
Termination
The electrical connection at each end of the SCSI bus, composed of a
set of resistors.
μ
s
Microsecond
One millionth of a second.
