Waking up the scanner
When the scanner is first turned on, it does a self-test and then goes to
sleep. A VME master processor must wake the scanner up by interrupting
it (writing any value to the scanner’s ID area), which moves the scanner
from sleep mode to program mode. Chapter 7 explains how to wake up
the scanner.
Chapter 8 provides additional programming examples.
